A Supreme Court under the Philippine Commission and the organic acts of the United States.
Mistake of Fact
Held that an honest mistake of fact, if it was not due to negligence or bad faith, removes criminal liability where the act would have been lawful had the facts been as the accused believed them. Ah Chong, who fatally stabbed his roommate in the dark believing him to be a robber, was acquitted.
Liberal Construction of Rules — Substitution of the Real Party in Interest on Appeal
Although the priest who sued was not the real party in interest, the Supreme Court itself amended the pleadings and decision on appeal to substitute the Roman Catholic Church as plaintiff and affirmed the judgment, holding that procedural rules are means to facilitate justice and that no litigant has vested rights in technicalities where substantial rights are not prejudiced.
Test of Negligence (Reasonable Foresight of the Prudent Man); Last Clear Chance
Laid down the classic test of negligence: whether the defendant used the care and caution that an ordinarily prudent person would have used in the same situation, judged by whether a prudent man in the defendant's position would have foreseen harm as sufficiently probable to guard against it. Also applied the last clear chance rule: the party who had the last fair chance to avoid the harm and failed to do so is liable despite the other party's earlier negligence.
An attempt must be an attempt at a specific crime. Overt acts that do not clearly show which felony was intended cannot be punished as an attempt at the graver one
The classic case on overt acts under Article 6. A man caught at dawn prying boards off a store wall with an iron bar was convicted of attempted robbery below. The Supreme Court held that nothing showed he meant to rob rather than do something else once inside. His acts proved only an intent to enter by force, so he was guilty of attempted trespass to dwelling. Acts open to two readings cannot ground an attempt at the more serious crime.
The 1935 Constitution takes effect, through the war and the Japanese occupation.
Separation of powers and judicial review; the Electoral Commission, as sole judge of legislative election contests, has the implied power to fix the period for filing protests
Laurel's ponencia laid down the Philippine theory of judicial review: when constitutional organs clash over their powers, the judiciary, with the Supreme Court as final arbiter, allocates constitutional boundaries. This is not judicial supremacy, and it is confined to actual cases and the lis mota. On the merits, the Court held that the Electoral Commission, as sole judge of contests involving members of the National Assembly, has the implied power to fix the period for filing election protests. The Assembly's confirmation of unprotested members could not cut off that period.
Mistake of fact excuses only when committed without fault or carelessness; excess in the performance of duty is only an incomplete justifying circumstance
Two officers who shot and killed a sleeping man they took to be an escaped convict, without first making any inquiry, were held guilty of murder qualified by treachery, not homicide through reckless imprudence. An intentional killing cannot be reckless imprudence, and a mistake of fact excuses only when it is made without fault or carelessness. The officers acted in the performance of duty, but the killing was not its necessary consequence, so the incomplete justifying circumstance of Article 11(5) lowered the penalty under Article 69.
Independence, still under the 1935 Constitution.
Regalian doctrine: land not acquired from the State belongs to the public domain unless possessed since time immemorial; an alien cannot obtain registration under the Public Land Act
Denied registration to an alien whose predecessors had possessed a residential lot since 1880. Lands not acquired from the Government by purchase or grant belong to the public domain. The only exception is possession since time immemorial, which justifies a presumption that the land was never public (Cariño v. Insular Government), and possession since 1880 did not qualify. Because the predecessors never applied for confirmation, they had no vested right to transmit. Their possession could be used only by a qualified applicant, not by an alien disqualified under Sections 48 and 49 of C.A. No. 141.
Conflict of interest: a lawyer consulted by one party may not later represent the adverse party in the same case
A lawyer-client relationship arose when Mrs. Hilado's papers were reviewed by Atty. Francisco's firm and he sent her a written opinion, even though he declined the case. That relationship alone disqualified him from later appearing for her opponents in the same case, without any inquiry into what confidential information he received. The Court adopted 'the bare relationship of attorney and client as the yardstick for testing incompatibility of interests'.
Contra Proferentem Rule
The Court applied the rule that doubtful or obscure terms in an insurance policy's exception clause are construed strictly against the insurer and liberally in favor of the insured (Article 1377, Civil Code). A watchman shot while accompanying a policeman to a house being robbed died by accident, and his death did not fall within the exclusions for making an arrest as an officer of the law or for assault or murder.
Regulatory Purpose
Taxation may be used as an implement of police power to stabilize or protect industries. The Sugar Adjustment Act, which levied a tax to fund stabilization of the sugar industry, was upheld as a valid exercise of both the taxing and police powers.
Proximate Cause
Defined proximate cause as the cause which, in a natural and continuous sequence unbroken by any efficient intervening cause, produces the injury and without which the injury would not have occurred. The carrier's negligence was the proximate cause despite a subsequent act.
Last Clear Chance (Checks)
Ruled that even if a depositor is negligent in signing blank checks, the bank is liable for the resulting loss if it had the last clear chance to detect the forgery by exercising the ordinary care of a bank in verifying signatures before paying out.
Public Purpose
Public funds may be appropriated only for a public purpose. An appropriation for roads on land that was private property when the law was passed and approved serves a private purpose and is void, and a later donation of the land to the government does not cure it. The Court also recognized a taxpayer's standing to challenge an illegal expenditure of public funds.
Immovable Property by Destination
Movable machinery becomes immovable by destination under Art. 415(5) only if it is an essential and principal element of an industry or works carried on in a building or on a piece of land. A bus company's repair-shop tools were merely incidental to its transportation business, which is not carried on in a building or on land, so they remained movable and could not be assessed realty tax.
Intestate Shares / Surviving Spouse and Child
Held that when a person dies intestate leaving a surviving spouse and only one legitimate child, the spouse and the child share the estate equally under Art. 996 of the Civil Code, the plural "children" including the singular. Art. 892, which gives the spouse a legitime of one-fourth when there is one child, governs testamentary succession and cannot be used to reduce the spouse's intestate share.
Preterition / Total Omission of Compulsory Heir
The total omission from a will of compulsory heirs in the direct line (here, the testatrix's parents), who are neither instituted nor expressly disinherited, is preterition. Under Art. 854 it annuls the institution of heir, while devises and legacies stand insofar as they are not inofficious. Because the will contained nothing but the institution of a universal heir, the whole will was void and the estate passed by intestacy. The Court also distinguished preterition from ineffective disinheritance.
Nationality Principle in Succession
The national law of the decedent governs the order of succession, the amount of successional rights, the intrinsic validity of testamentary provisions and the capacity to succeed (Arts. 16, par. 2 and 1039, Civil Code). Art. 17, par. 3 does not override Art. 16, so where the decedent's national law (here, Texas law) has no forced heirs, his heirs cannot claim legitimes under Philippine law, even over property in the Philippines.
Jurisdiction by Estoppel (Laches)
A party that, over some fifteen years, invoked the court's jurisdiction to seek affirmative relief and submitted its case for adjudication on the merits was held barred by laches from raising the trial court's lack of subject-matter jurisdiction for the first time after an adverse appellate decision. The Court acknowledged the general rule that lack of jurisdiction over the subject matter may be raised at any stage, but refused to annul proceedings on the peculiar facts of the case.
Limits of a lawyer's criticism of the courts; disciplinary proceedings are sui generis
Recognized that lawyers may criticize courts, and even consider it a duty to do so, 'in properly respectful terms and through legitimate channels'. The Court held that 'Intemperate and unfair criticism is a gross violation of the duty of respect to courts' and warrants discipline even after the case has ended. It also described disciplinary proceedings as sui generis investigations into a lawyer's fitness, and suspended Atty. Almacen indefinitely.
Option Contracts / Lack of Separate Consideration
An option to sell that is not supported by a consideration distinct from the price does not bind the offeror as an option: she may withdraw it before acceptance by communicating the withdrawal. Until it is withdrawn, however, it is an offer to sell, and acceptance before withdrawal produces a perfected contract of sale. Harmonizing Arts. 1324 and 1479, the Court reiterated Atkins, Kroll & Co. v. Cua Hian Tek and abandoned the contrary view in Southwestern Sugar & Molasses Co. v. Atlantic Gulf & Pacific Co.
Proclamation 1081, the 1973 Constitution, EDSA and the Freedom Constitution.
Partial Validity of Wills
The invalidity of some provisions of a will does not void the whole will where the valid parts can be separated (Art. 792, Civil Code). Although a probate court may pass on intrinsic validity first when a will appears void on its face, testacy is preferred to intestacy, and the court must try to give effect to the testator's wishes. Here the surviving husband's renunciation and conformity validated the testatrix's partition of the conjugal estate.
Double Taxation
Congress may validly delegate taxing power to municipalities, and double taxation in general is not forbidden by the Constitution. It becomes objectionable only when the same taxpayer is taxed twice by the same jurisdiction for the same purpose, not when one tax is imposed by the State and another by a municipality. The Court upheld Section 2 of the Local Autonomy Act and Tanauan's per-gallon production tax on soft drinks, which was neither a percentage tax nor a specific tax.
Binding deposit receipt is merely conditional; concealment in life insurance
Held that a binding deposit receipt conditioned on the insurer being satisfied that the applicant is insurable on standard rates is merely an acknowledgment of the premium and application, not an insurance contract; once the insurer disapproved the application, no contract was perfected and the premium had to be refunded. It also held that an applicant who withheld his child's congenital condition (Down syndrome; the decision's term is 'mongoloid child') was guilty of concealment, which entitles the insurer to rescind whether intentional or not.
Foreign Divorce / Alien Spouse
Held that a divorce validly obtained abroad, binding on the alien spouse under his national law, is recognized in the Philippines as against him: the American ex-husband was no longer the Filipino wife's husband and could not claim rights over alleged conjugal property here, having also represented to the divorce court that there was no community property.
BP 22 punishes the making and issuing of a worthless check, not the failure to pay a debt. It is a valid police-power measure and does not violate the ban on imprisonment for debt
The decision that upheld the Bouncing Checks Law. The gravamen of BP 22 is putting a worthless check into circulation, an offense against public order and not against property. The law is malum prohibitum and deliberately cut loose from estafa. Estafa had never reached checks issued for pre-existing debts. Later BP 22 cases build on this reading of the offense.
Publication of Laws / Due Process
Held that publication is indispensable to the effectivity of all laws, including presidential decrees, executive orders and administrative rules that enforce or implement law. Under Article 2 of the Civil Code as it then stood, the publication had to be in full and in the Official Gazette. Interpretative regulations and purely internal rules were exempted.
The charter the Bar examines — and the one almost every case here reads.
Docket Fees as Jurisdictional
A court acquires jurisdiction over a case only upon payment of the prescribed docket fee; an amendment of the complaint cannot vest jurisdiction where the correct fee was not paid on the original. Henceforth all pleadings must state the amount of damages prayed for in both the body and the prayer, and a pleading that does not shall not be accepted or admitted, or shall be expunged.
Once an Information Is Filed, Its Disposition Rests in the Sound Discretion of the Court
The prosecutor controls a criminal prosecution, but once a complaint or information is filed in court, any disposition of the case, whether dismissal, conviction or acquittal, rests in the sound discretion of the court. A motion to dismiss filed by the fiscal, even on the instruction of the Secretary of Justice, may be granted or denied by the court, which is not bound by the prosecution's opinion.
Uncounselled custodial confessions and forced re-enactments are inadmissible
Held that extrajudicial confessions taken without counsel of the suspects' own choosing are inadmissible. A re-enactment of the crime that suspects in police custody are made to perform is covered by the ban against self-incrimination, unlike mechanical acts such as a physical examination or footprinting. With the confessions and the re-enactment excluded, two appellants were acquitted, and the third was convicted only of homicide, on the strength of his own admission of the killing.
The death must be the direct, natural and logical consequence of the wound. An efficient intervening cause, here a later tetanus infection, breaks the chain of causation and bars a homicide conviction
The leading criminal case on proximate cause and the efficient intervening cause under Article 4. The victim died of severe tetanus 22 days after a bolo wound to his palm. Medical evidence on incubation made it likely that the wound was infected well after the hacking. That doubt defeated the homicide conviction. The Court added that criminal acquittal does not necessarily end civil liability.
Lifeblood doctrine, but taxes must be collected according to law; reasonable pay for services actually rendered is deductible
Source of the lifeblood doctrine, which the Court balanced with the rule that taxes must be collected in accordance with law. It upheld Algue's deduction of P75,000 in promotional fees as reasonable pay for services actually rendered, and held that a protest that is not pro forma suspends the period to appeal to the CTA.
Reciprocal Obligations / Suspension of Performance
In a sale of a house and lot, the seller must deliver the house in a condition fit for its intended use. Where the GSIS delivered an uninhabitable shell, the buyer could suspend paying amortizations, and the GSIS could not cancel the award, because in reciprocal obligations neither party incurs delay if the other does not comply (Art. 1169). Using its equity jurisdiction, the Court did not order the house completed. It reformed the price to the value of the land and the unfinished house as of the date the contract was perfected.
Without proof of a prior agreement, each participant answers only for his own act. One who commits a felony answers for its graver result even if he intended less (Art. 4)
Taught for three points. First, there is no conspiracy where the accused met by chance and shared no criminal purpose, so liability is individual. Second, pouring gasoline on a person, knowing what it is, while one's companions are fooling around is reckless imprudence. Third, setting the victim alight as a prank is homicide under Article 4, because even burning his clothes would be a felony. Treachery requires a deliberate choice of means and was absent.
Docket Fees — Payment Within a Reasonable Time; Lien on Judgment
Tempered Manchester: although it is the payment of the prescribed docket fee that vests the trial court with jurisdiction, the court may allow payment within a reasonable time but not beyond the prescriptive or reglementary period. Where a judgment awards a claim not specified in the pleading, or left for determination by the court, the additional filing fee constitutes a lien on the judgment.
Carrier-passenger relationship continues for a reasonable time after disembarkation; extraordinary diligence toward passengers
The carrier-passenger relationship does not end on landing but continues until the passenger has had a reasonable time to leave the carrier's premises, including a reasonable time to claim his baggage, judged by all the circumstances. A ship passenger struck by a stevedore's crane while retrieving his cargo an hour after docking was still a passenger, so the carrier's failure to exercise extraordinary diligence (Arts. 1733, 1755 and 1756, Civil Code) made it liable despite his contributory negligence.
Neglect and abandonment of a client's cause; misappropriation of client money
A lawyer who bragged of closeness to a judge, asked for money to 'buy' a restraining order, pocketed a supposed P10,000 court deposit, and withdrew without finding a replacement, so that his client was evicted, was suspended indefinitely. He was also ordered to return P11,000. The Court stressed that a lawyer who takes a client's cause 'covenants that he will exert all effort for its prosecution until its final conclusion.'
Trademark infringement and unfair competition: the casual purchaser test; side-by-side comparison is not the final test
Held that side-by-side comparison is not the final test of similarity; the question is whether the general impression on the eye of a casual purchaser who is unsuspicious and off his guard is likely to cause confusion, taking into account the cost of the goods (catsup being a low-priced, everyday item). It also held that registration in the Supplemental Register gives no basis for an infringement action, but using a competitor's embossed bottles to pass off one's goods is unfair competition.
Fiduciary Duty of Banks
Because banking is a business affected with public interest, a bank must treat its depositors' accounts with meticulous care, mindful of the fiduciary nature of the relationship. A bank's unexplained failure to credit a deposit, which caused checks to be dishonored, and its slowness in correcting the error justified moral damages to a corporate depositor whose reputation was impaired and exemplary damages for wanton conduct.
There is no frustrated rape. Rape is consummated by any penetration of the female organ, however slight, and is only attempted if there is none
Settled that the frustrated stage does not apply to rape. From the moment of carnal knowledge the offender has performed every act and the felony is complete. Without penetration, not all acts of execution were performed, so the crime is only attempted. The Court called People v. Eriña (1927), which had found frustrated rape, a “stray” decision. It called the Code's reference to frustrated rape with homicide a “dead provision.” Later refined in People v. Campuhan on what counts as penetration.
Good-faith belief of ownership negates criminal intent in theft; courts must weigh customary ownership claims carefully
An illiterate Bontoc tribeswoman convicted of stealing sugarcane and bananas from part of a communal tayan was acquitted. The prosecution failed to pin down where the plants were taken from and so failed to prove who owned them, and the Court found that she took them believing them to be her own and so had no criminal intent. The Court described the case as a clash between ownership founded on custom and tradition and a documented claim resting on the same customs, and it left the ownership questions to a civil action.
Practice of law, broadly defined, as a constitutional qualification for COMELEC Chairman
Upheld Christian Monsod's appointment as COMELEC Chairman, adopting a broad definition of practice of law: 'any activity, in or out of court, which requires the application of law, legal procedure, knowledge, training and experience.' Monsod's work as a lawyer-economist, manager, negotiator and legislator was held to satisfy the ten-year requirement. The Court was sharply divided: by Justice Gutierrez's count, five of the fourteen members found that Monsod had practiced law, four found he had not, and two voted in the result only because no grave abuse of discretion was shown.
Checks issued only to cover a "warranty deposit" in a lease arrangement, which the drawer never received or used, are not issued "to apply on account or for value," and their dishonor does not make out a violation of BP 22
A leading acquittal under the Bouncing Checks Law. The lower courts had convicted on the reasoning that BP 22 is malum prohibitum, so the only question is whether the law was violated. The Supreme Court looked instead at why the checks were drawn. They collateralized an accommodation for a warranty deposit that stayed with the financing company and was never used by the drawer, who was only renting the equipment and had openly said he had no funds. The Court described the law's purpose as protecting the banking system and legitimate check users, not a tool for schemes that skim business clients. It is cited on the “account or for value” element, but it turned on unusual facts and is best read as fact-bound rather than as a general defense.
Accident insurance: meaning of 'accident'; negligence of the insured is not willful exposure to needless peril
The Court held that the death of an insured who, believing his handgun unloaded after removing the magazine, pointed it at his temple and it fired, was an accident covered by a personal accident policy. He did not willfully expose himself to needless peril because he did not know of the danger, and his negligence did not bar recovery since no policy exception covered it. The insurer's good-faith resistance on a question of first impression did not, however, warrant moral and exemplary damages or attorney's fees.
Kidnapping does not require confinement in an enclosure, because any deprivation of liberty suffices. A ransom note delivered after the kidnapping was consummated is not an impossible crime
Cited on three points. Illegal detention is committed by any restraint of liberty, even while moving the victim from vehicle to vehicle in public. A co-accused who only wrote the ransom note cannot invoke the impossible-crime clause, because the kidnapping was already consummated. Conspiracy may be inferred from complementary acts aimed at a common goal. The Court also applied People v. Marti: evidence gathered by a private person is not covered by the Bill of Rights.
Legal-clinic services as practice of law; prohibition on advertising legal services
Held that The Legal Clinic, Inc.'s advertised 'legal support services' amounted to practice of law, which only Bar members in good standing may engage in; employing paralegals did not change this. The Court also held that its advertisements (including a quoted fee) fell outside the narrow allowed exceptions (reputable law lists, simple professional cards, announcements). It enjoined the advertisements and reprimanded Atty. Nogales. Noting that a corporation cannot be organized for or engage in the practice of law, it referred the legality of the respondent's corporate purpose to the Solicitor General for possible quo warranto proceedings.
Intergenerational Responsibility / Legal Standing
Held that minors, suing through their parents in a class suit, may sue for themselves, their generation and generations yet unborn to enforce the right to a balanced and healthful ecology, based on the concept of intergenerational responsibility. It also ruled that the complaint stated a cause of action anchored on Section 16, Article II of the Constitution, and set aside its dismissal.
Limits of management prerogative — employees must be heard on, or at least informed of, disciplinary rules affecting their tenure
Held that management prerogatives are limited by law, the CBA and general principles of fair play and justice. A code of discipline that affects security of tenure is not a purely business decision, so management must at least properly inform employees of it, and a CBA management-rights clause does not waive the employees' right to take part in discussing matters that affect their rights. The Court upheld the NLRC order that PAL discuss its new Code of Discipline with the union.
Death of the accused pending appeal of his conviction extinguishes his criminal liability and the civil liability based solely on the offense (ex delicto). Civil liability that also rests on another source of obligation survives, but only through a separate civil action
The controlling rule on Article 89(1) of the Revised Penal Code. The en banc Court abandoned People v. Sendaydiego (1977) and the cases that followed it, which had kept the appeal alive to decide the deceased accused's civil liability ex delicto. The Court reverted to the older rule of People v. Castillo: once the accused dies before final judgment, there is no defendant and no crime to ground civil liability ex delicto. Its four-point summary states the rules. Civil liability that can also rest on law, contract, quasi-contract or quasi-delict survives, but must be pursued in a separate civil action. Where the civil action was instituted with the criminal case, prescription is interrupted while that case was pending.
Psychological Incapacity — Gravity, Juridical Antecedence, Incurability
The Court's first extended interpretation of Article 36. It confined psychological incapacity to "the most serious cases of personality disorders" showing an utter insensitivity or inability to give meaning and significance to the marriage, described it as a mental (not physical) incapacity, and adopted the three characteristics of gravity, juridical antecedence and incurability. Gravity and juridical antecedence survive. Tan-Andal v. Andal (2021) rejected the view that psychological incapacity is a mental incapacity or personality disorder that must be proven by expert opinion, abandoned the second Molina guideline, and read incurability in the legal rather than the medical sense.
Evidence Taken by One Spouse in Violation of the Other's Privacy of Communication Is Inadmissible
Documents a wife forcibly took from her husband's clinic to prove his infidelity are inadmissible "for any purpose in any proceeding." The constitutional inviolability of the privacy of communication and correspondence applies even between spouses, and marriage does not strip a person of the right to privacy.
Piercing the corporate veil: the control-fraud-proximate cause (instrumentality) test
Applied the instrumentality or alter ego test (control, use of that control to commit fraud or wrong, and proximate causation of injury; absence of any one element prevents piercing), together with probative factors such as common stock ownership and identical directors and officers, to treat a sister corporation that emerged to evade a labor judgment as the judgment debtor's business conduit. Whether a corporation is a mere alter ego is purely a question of fact.
Right of First Refusal
A lease clause giving the lessee the first chance to buy if the lessor decides to sell is a right of first refusal, not an option, and needs no consideration separate from the lease. A sale to a third person who knew of that right is rescissible, and the grantee may be allowed to buy the property at the price the third person paid. On this remedy the Court modified, or at least amplified, Ang Yu Asuncion, which had confined the remedy to damages.
Psychological Incapacity (Art. 36)
Held that the senseless and prolonged refusal of one spouse to consummate the marriage, without any medical or physical cause, is equivalent to psychological incapacity under Article 36 of the Family Code and is a ground for declaration of nullity.
The Molina Guidelines (Art. 36)
Laid down the eight guidelines that governed Article 36 for twenty-four years. In Tan-Andal v. Andal (2021) the Court expressly abandoned the second guideline, which required the root cause to be medically or clinically identified and proven by experts, holding that psychological incapacity is a legal and not a medical concept. It also restated the incurability requirement in a legal rather than medical sense. The other guidelines are still cited, as read through Tan-Andal.
Exclusive Use of Title "Attorney"
A Shari'a Bar member working as a Shari'a court clerk was reprimanded for calling himself 'attorney' and for insulting language in private letters. The Court held that the title 'attorney' belongs only to those who passed the Bar Examinations, were admitted to the Integrated Bar of the Philippines and remain members in good standing. Shari'a Bar members may be called 'counsellors' but may practice only before Shari'a courts.
One who helps conceal what he believes is a corpse, when the victim is in fact alive and then drowns, commits a felony and is liable for the graver result under Article 4(1). Abuse of superior strength requires a deliberate use of force out of proportion to the victim's means of defense
The textbook illustration of praeter intentionem under Article 4(1). Concealing the body of a crime is itself a felony, as an accessory's act, so a person who throws a still-living victim into a well is answerable as a principal for the resulting death. The co-accused was nonetheless acquitted, and the reasons are just as often taught. He could not be convicted of homicide by drowning under an information charging murder by stabbing. And as the principal's brother-in-law, he was exempt from liability as an accessory under Article 20. The case is also cited for the rule that abuse of superior strength must be deliberately sought, not inferred from the outcome of a fight.
Hierarchy of Courts (Rule 65 vs. NLRC)
Established that petitions for certiorari (Rule 65) assailing NLRC decisions must be filed first with the Court of Appeals — not directly with the Supreme Court — in accordance with the doctrine of hierarchy of courts.
Custodial Investigation Rights
Outlined the definitive 10-point checklist that law enforcement officers must strictly follow during custodial investigations to safeguard the accused's Miranda rights — from the right to remain silent to the right to competent and independent counsel.
The Serrano Doctrine — Full Backwages for Termination Without the Required Notice
Held that terminating an employee for a just or authorized cause without the required notice does not violate the constitutional due process clause and does not void the termination. It only makes the termination 'ineffectual', so the employer must pay full backwages. In this redundancy case the employee received separation pay plus full backwages until the decision became final; for just-cause dismissals, backwages run until it is determined that the dismissal was for just cause. Agabon v. NLRC (2004) expressly abandoned the Serrano doctrine in favor of a stiffer Wenphil-type indemnity (nominal damages), and JAKA Food Processing Corp. v. Pacot (2005) applied nominal damages to authorized-cause terminations.
Consummated rape requires proof that the penis touched the labia or slid into the female organ. Merely grazing the surface or touching the mons pubis is at most attempted rape
The en banc clarification of Orita's “any penetration, however slight” rule. “Touching” means touching the labia as part of penile penetration, not mere contact with the external surface. Without such proof the crime is attempted rape, not consummated rape. Here that difference turned a death sentence into an indeterminate term. It is the usual citation for where attempted rape ends and consummated rape begins.
Constitutionality of IPRA (Tie Vote)
The Court split 7-7 on the constitutionality of the Indigenous Peoples' Rights Act (R.A. 8371). The votes stayed tied on redeliberation, so the petition was dismissed under Rule 56, Section 7, and the IPRA remained in force. The dismissal does not declare the IPRA constitutional. The native-title reasoning (that ancestral domains held under native title were never public land and do not offend the Regalian doctrine) appears only in the separate opinions of Justices Puno and Kapunan, and seven Justices disagreed.
A President's resignation may be inferred from the totality of his prior, contemporaneous and posterior acts; a non-sitting President has no immunity from criminal suit; prejudicial publicity requires proof of actual prejudice
The Court held that EDSA II, unlike EDSA I, was an exercise of free speech and assembly within the 1987 Constitution, so Arroyo's succession was open to judicial review. Applying a totality test to Estrada's acts before, during and after January 20, 2001, it found that he had resigned. It treated his claim of temporary inability as a political question already settled by Congress's recognition of Arroyo. It held that presidential immunity lasts only during tenure, so the Ombudsman could investigate him for plunder, bribery and graft, and it rejected his prejudicial-publicity claim for lack of proof of actual prejudice.
Best Interest of the Child Over Religious Interpretation
The welfare of the children is the controlling consideration in custody disputes. A mother who converted to Islam before marrying a Muslim and later reverted to Catholicism is judged by the Family Code standard, not by Islamic moral standards alone, in determining her fitness for custody. Because the father failed to prove her unfit under either Muslim law or the Family Code, the Court awarded her custody and gave the father visitation rights.
Creation of Attorney-Client Relationship
A lawyer-client relationship arises once a person consults a lawyer for professional advice or help and the lawyer voluntarily permits or acquiesces in the consultation. No retainer, payment or prior engagement is needed, and a close personal relationship does not prevent it. A lawyer who used a client's filing-fee deposit as legal fees and did not file the complaint violated Rules 16.01 and 18.03 of the Code of Professional Responsibility and was suspended for one year.
Where the primary and ultimate purpose of seizing a victim is to kill him, the deprivation of liberty is only incidental and is absorbed in the killing. The crime is murder or homicide, not kidnapping
The en banc statement of the rule that specific intent, not the mere fact of abduction, separates kidnapping from murder. Following People v. Puno and the older Ancheta line, a victim taken from his home and later found dead is a homicide victim, not a kidnap victim, when the information shows that the aim was to kill. The decision is also cited on four other points. Intent to kill can be shown from the weapons used and the nature, number and location of wounds. Motive is not specific intent and need not be proved. A lookout who stays behind is a co-conspirator and principal even though absent from the killing. Treachery and abuse of superior strength cannot be presumed when no one saw how the victim was killed.
Robbery with homicide is a single, indivisible special complex crime. Treachery does not qualify it, but it is a generic aggravating circumstance when the homicide victim is killed treacherously, and it must be alleged in the information
The en banc ruling on treachery in robbery with homicide, a question on which earlier decisions had conflicted (Bariquit, Cando). It adopted Spanish Supreme Court precedent. Treachery attaches to the constituent homicide and aggravates the penalty, though the crime stays a crime against property. The decision also restates the core rules of the special complex crime. The intent to rob must precede the killing. The killing may occur before, during or after the robbery. All principals in the robbery are liable unless they tried to prevent the killing.
Battered Woman Syndrome — elements for self-defense; BWS as mitigating circumstance
Treating battered woman syndrome (BWS) as "a novel concept in our jurisprudence", the Court held that BWS can support self-defense only if the cycle of violence, the woman's actual fear of imminent harm, and probable grave harm at the time of the killing are all proved. Genosa failed to prove these and had no unlawful aggression to repel, so her parricide conviction stood. The BWS-related psychological paralysis and passion and obfuscation were credited as mitigating circumstances, cutting her sentence from death to an indeterminate term.
Nullity of the Second Marriage under Art. 36 Is No Defense to Bigamy
A later judicial declaration that the second marriage is void for psychological incapacity (Art. 36, Family Code) does not extinguish criminal liability for bigamy. The crime is consummated once a second marriage is contracted while a valid first marriage subsists, and a void marriage may still produce legal effects, including criminal liability. The Court also held that a certified copy of a marriage contract outweighs certifications that no record of the marriage exists.
DNA Evidence Is Admissible; Compelled DNA Sampling Does Not Violate the Right Against Self-Incrimination
The Court applied the Daubert relevance-and-reliability standard to DNA evidence obtained through PCR amplification and STR analysis, listed the factors for weighing it (collection, handling, possibility of contamination, procedure, standards and the analyst's qualifications), and held that the privilege against self-incrimination covers only testimonial compulsion, not blood or DNA samples.
Independent Contractor / Control Test
Held that a radio and television program host engaged for his unique skills, talent and celebrity status, paid huge negotiated talent fees, and not controlled in how he performed his work was an independent contractor, not an employee. The control test (control over the means and methods, not merely the result) is the most important element. Because his claims rested on his contract, they were for breach of contract and belonged in the regular courts, not before the Labor Arbiter.
Monthly-Paid Employees / No Work, No Pay; Sec. 2, Rule IV, Book III IRR Void
Held that monthly-paid employees cannot claim pay for every day of the year under Sec. 2, Rule IV, Book III of the Omnibus Rules Implementing the Labor Code, which Insular Bank of Asia and America Employees' Union (IBAAEU) v. Inciong had declared void. Under the "no work, no pay" rule, the right to pay for unworked days is generally limited to the regular holidays. A divisor below 365 is not automatically underpayment; for a Monday-to-half-Saturday schedule the minimum allowable divisor is 287, so the employer's 304 divisor was lawful. The Court also upheld the CA's outright dismissal of a certiorari petition that failed to specify how the NLRC gravely abused its discretion.
Non-Competing Goods / Trademark
Applying the Trademark Law (RA 166) and the Paris Convention rather than the IP Code, the Court held that use of the identical GALLO mark on cigarettes did not infringe the GALLO wine mark: protection reaches only identical, similar or related goods where confusion is likely, and wines and cigarettes are unrelated goods sold through different channels of trade. Alcohol and tobacco are related only in special circumstances, and without passing off there was no unfair competition.
Dismissal for Just Cause Without Statutory Due Process; Nominal Damages (Agabon Doctrine)
Held that when a dismissal is for a just cause but the employer does not comply with the statutory notice requirements, the dismissal stands but the employer must pay nominal damages (P30,000 to each employee here) for violating the employee's right to statutory due process. The Court expressly abandoned the Serrano v. NLRC rule (full backwages until a judicial finding of just cause) and returned to Wenphil with a stiffer sanction. It also distinguished statutory due process under the Labor Code from constitutional due process.
Independence principle in standby letters of credit; beneficiary may invoke it; fraud exception
Held that a standby letter of credit is separate from the underlying contract, so the issuing banks had no duty to verify the beneficiary's certification of default, and that the beneficiary itself may invoke the independence principle; requiring disputes to be settled first would turn the credit into a mere guarantee. Fraud is an exception, but an injunction requires clear proof of fraud, fraudulent abuse of the credit's independent purpose, and irreparable injury.
Text messages as ephemeral electronic communications — proven by testimony of a party or person with personal knowledge
Held that text messages are 'ephemeral electronic communications' under the Rules on Electronic Evidence, which may be proven by the testimony of a person who was a party to them or who has personal knowledge of them. On that evidence, among others, the Court dismissed a Court of Appeals employee for grave misconduct after she solicited P1,000,000 in exchange for a favorable decision.
Hierarchy of Courts; Estoppel From Assailing Jurisdiction; Deficient Docket Fees Paid in Good Faith
A petition for certiorari filed directly with the Supreme Court without special and important reasons violates the hierarchy of courts and may be dismissed on that ground alone. Applying Sun Insurance, the Court held that deficient docket fees paid within the prescriptive period and without intent to defraud do not oust the court of jurisdiction, that fees for unspecified damages are a lien on the judgment, and that a party who participated for years and sought affirmative relief is estopped from raising non-payment of fees.
Delegation of Legislative Power
Upheld R.A. 9337's standby authority for the President to raise VAT to 12% upon specified fiscal conditions. The Court restated the completeness and sufficient-standard tests for valid delegation, and characterized the provision as contingent legislation: a delegation of the ascertainment of facts, not of legislative power, since the President 'shall' impose the rate once either condition is met. It also upheld the Bicameral Conference Committee's changes under the enrolled bill doctrine and the germaneness rule.
The "Fresh Period Rule": 15 Days to Appeal From Denial of a Motion for New Trial or Reconsideration
To standardize appeal periods, the Court allowed a fresh period of 15 days to file a notice of appeal in the RTC, counted from receipt of the order denying a motion for new trial or reconsideration, instead of only the balance of the original period. It extended the same rule to appeals under Rules 40, 42, 43 and 45.
Pressing a chemical-soaked cloth on a woman's face while lying on top of her, without any act of undressing or touching her private parts, is not an overt act of rape. It is at most unjust vexation, punished as light coercion
The modern application of Lamahang's overt-act test to attempted rape. An overt act must be one that, if carried to completion, would logically and necessarily ripen into the particular crime. An act whose objective is ambiguous is an attempt at an indeterminate offense, which the Code does not punish. The Court acquitted a medical student identified by circumstantial evidence as the intruder, because nothing he did pointed necessarily to carnal knowledge. Reading rape into the act would have been speculation. The decision also shows that an information for attempted rape can support a conviction for unjust vexation where it alleges the acts that constitute it.
No-spouse employment policy — valid only on proof of a reasonable business necessity (BFOQ)
Struck down a company rule requiring one of two co-employees who marry each other to resign. Such a no-spouse policy is valid only if the employer proves a reasonable business necessity, the local standard that parallels a bona fide occupational qualification. Star Paper showed none, so the policy was an invalid exercise of management prerogative and the employees' separations were illegal.
Calling-out power vs. emergency powers: the President may declare a state of national emergency, but cannot take over private businesses without a law from Congress
Upheld PP 1017 as a valid exercise of the President's calling-out power, but struck down its provisions letting the President issue decrees and use the AFP to enforce all laws and decrees. Held that declaring a state of national emergency does not by itself let the President take over private businesses affected with public interest; that needs prior legislation. Also declared unconstitutional the warrantless arrests of David and Llamas, the dispersal of the KMU rallies, the prior restraint on media, and the warrantless search of the Daily Tribune offices.
Dismissal of the Complaint for the Plaintiff's Fault Does Not Carry the Counterclaim With It
Under Section 3, Rule 17 of the 1997 Rules, the dismissal of a complaint due to the plaintiff's fault is without prejudice to the defendant's right to prosecute any pending counterclaim, compulsory or permissive, in the same or a separate action. The Court expressly abandoned BA Finance Corp. v. Co and all inconsistent rulings.
Substituted Service of Summons Requires Strict Compliance, Shown in Detail in the Sheriff's Return
Laid down the requirements for valid substituted service: impossibility of prompt personal service (several attempts, meaning at least three tries, preferably on at least two different dates, within about one month), specific details of those efforts in the Return, and service on a person of suitable age and discretion residing in the defendant's dwelling, or on a competent person in charge of the defendant's office. A Return couched in general terms does not enjoy the presumption of regularity, and the substituted service is void.
Two-Tiered Test for Employment Status
Adopted a two-tiered test of employment for cases where the control test alone gives an incomplete picture, as when the worker held several positions: (1) the putative employer's power to control the means and methods of the work, and (2) the underlying economic realities of the relationship, with the worker's economic dependence on the employer as the benchmark. Also held that a diminution in pay amounts to constructive dismissal.
Carrier liable for cargo lost on a vessel it does not own; voyage charter is a contract of carriage
Held that a carrier which contracted under a voyage charter to transport a shipper's cargo, chose the vessel, and represented itself as a common carrier is liable for the loss of the cargo even though it did not own the vessel that sank; non-ownership does not negate its character and duties as a common carrier. The charter party, not the bill of lading issued by the vessel owner, was the contract of carriage, and a stipulation that cargo insurance is for the charterer's account does not exempt the carrier.
Pre-1997 assessments need not state their legal and factual bases; an assessment not protested within 30 days becomes final and unappealable
Before RA 8424, former Section 270 of the NIRC required the CIR only to notify the taxpayer of his findings. The requirement that an assessment state the law and facts on which it is based, on pain of being void, was a new rule added in 1997 by Section 228. It did not merely restate what the old law already required. Because BPI's 1988 assessments were valid under the old law and were not protested on time, they became final and unappealable.
There is no frustrated theft. Theft is consummated once the offender gains possession of the thing with intent to gain, even without any opportunity to dispose of it
The en banc ruling that theft has only two stages, attempted and consummated. It rejected the Court of Appeals' “free disposition” theory in People v. Diño and People v. Flores, long taught as the textbook examples of frustrated theft. It also disregarded Empelis v. IAC. Being caught at the supermarket exit or checkpoint with the goods does not make the theft frustrated. The taking itself produces the felony.
Employer Liability / Diligence of a Good Father
Employers are directly and primarily liable for the negligent acts of their employees. To escape liability, the employer must prove they exercised the diligence of a good father of a family in both the selection and supervision of the employee — a heavy burden.
An Ordinary Facsimile Transmission Is Not an Electronic Document or Electronic Evidence
Construing the Electronic Commerce Act in light of its legislative history, the Court held that "electronic data message" and "electronic document" do not include ordinary facsimile transmissions, which are paper-based. A fax, and a fortiori a photocopy of a fax, is not the functional equivalent of an original under the Best Evidence Rule, and its admissibility is governed by the ordinary rules on secondary evidence.
Freedom of Expression / Prior Restraint
Held that content-based prior restraints on speech, whether in print or broadcast media, carry a heavy presumption of invalidity and must pass the clear and present danger rule, while content-neutral regulations get intermediate review. It nullified the DOJ Secretary's and the NTC's official warnings against airing the "Garci" wiretap tapes as unconstitutional prior restraint, even though the warnings were never put into formal orders.
Chain of custody: the prosecution must account for every link from seizure to presentation in court, and the presumption of regularity cannot overcome the presumption of innocence
The foundational statement of the chain-of-custody rule for dangerous drugs. The drug is the corpus delicti. Because it is fungible and easily substituted, its identity must be proved by testimony about every hand that held it. The accused was acquitted because the officer who marked the sachets and the person who received them at the laboratory never testified. Search irregularities and a disregard of Section 21 of the IRR made it worse. It is the usual starting point for chain-of-custody arguments in RA 9165 appeals.
The Right to Security of Person as Freedom From Threat and as a Guarantee of Government Protection Under the Writ of Amparo
The first decision applying the Rule on the Writ of Amparo. It explained the writ's origin and summary nature (claims are proven by substantial evidence), and defined the right to security of person in three senses: freedom from fear, understood in the amparo context as freedom from threat; bodily and psychological integrity; and a guarantee of protection by the government, including effective investigation. The right exists even without an actual deprivation of liberty, and an amparo production order is not a search warrant.
Failure to meet continuing weight standards — analogous just cause (Art. 282(e)) and BFOQ
Held that an airline's weight standards for cabin crew are a continuing qualification of the job, so that failing to meet them is an analogous just cause for dismissal under Art. 282(e) (now Art. 297(e)) of the Labor Code, even without willfulness. The dismissal could also rest on the bona fide occupational qualification (BFOQ) defense, since the standards were reasonably connected to flight safety. The Court nonetheless awarded the steward separation pay as a measure of social justice.
Notice Requirement (FAN)
Under Section 228 of the NIRC and RR No. 12-99, the formal letter of demand and assessment notice must state in writing the law and the facts on which the assessment is based, or the assessment is void. Pre-assessment advice, a preliminary five-day letter, and audit working papers are not substitutes, because due process requires that the taxpayer be told the bases.
Police power and substantive due process: a legitimate aim does not save an ordinance whose means are unduly oppressive when less intrusive means are available
Struck down Manila Ordinance No. 7774, which barred hotels, motels, inns, lodging houses and similar establishments from offering short-time admission, 'wash-up' rates, or renting a room more than twice a day. The Court held it an arbitrary and unduly oppressive use of police power that violated substantive due process and the liberty of the establishments and their patrons, because less intrusive means were available. It also recognized the establishments' third-party standing to raise their patrons' rights.
OFW Rights / Unconstitutional 3-Month Cap
Declared unconstitutional the clause "or for three months for every year of the unexpired term, whichever is less" in the 5th paragraph of Sec. 10, R.A. 8042. The Court applied strict scrutiny and found that the clause violated equal protection and substantive due process. An illegally dismissed OFW is entitled to salaries for the entire unexpired portion of the contract, computed on the basic salary; overtime and leave pay are excluded unless the work was actually performed.
Taking a check that turns out to be unfunded, with intent to gain, is an impossible crime and not qualified theft, because the thing taken was worthless (factual impossibility)
The modern application of Intod v. Court of Appeals to a crime against property. A collector who kept a customer's postdated check had done everything needed for qualified theft. The crime was not produced only because the check bounced, an extraneous fact she did not know, so the crime was factually impossible. Her later receipt of marked cash was not a continuation of the theft, because theft is not a continuing offense. A separate scheme not alleged in the information could not be punished.
Labor-Only Contracting
Applied Art. 106 and D.O. 18-02 to the two agencies that supplied P&G's merchandisers, with different results. SAPS, with a paid-in capital of only P31,250 and workers doing merchandising directly related to P&G's business, was a labor-only contractor, so its workers were P&G's employees. Promm-Gem, which had substantial capital and its own facilities and treated the workers as its regular employees, was a legitimate contractor and the employer of its workers. The Court also affirmed that farming out work, whether core or peripheral, is a management prerogative if the work goes to a legitimate independent contractor.
Bail Pending Appeal Is Discretionary Even Absent the Bail-Negating Circumstances of Rule 114, Section 5
Where the RTC imposes imprisonment exceeding six years, the appellate court may still deny bail pending appeal even though none of the bail-negating circumstances in the third paragraph of Section 5, Rule 114 is present. If none is present, the court exercises sound discretion over all relevant circumstances; if one is present, bail must be denied or revoked. Bail pending appeal is allowed "with grave caution and only for strong reasons."
Reckless imprudence under Article 365 is a single quasi-offense, and its consequences only fix the penalty. A conviction or acquittal for one consequence bars prosecution for the others, and Article 48 does not apply to quasi-offenses
The controlling rule on charging quasi-offenses and on double jeopardy. Following Quizon and the Diaz–Buan line, the Court held that Article 365 penalizes the careless act, not its results. A driver already convicted of reckless imprudence resulting in slight physical injuries cannot be tried again for the homicide and damage to property caused by the same act. Going forward, every consequence must be alleged in one information and penalized separately, with no splitting of charges.
Valid Talaq as Defense Against Bigamy
Where both spouses are Muslims married under Islamic rites, P.D. No. 1083 governs the marriage and its dissolution, and a later civil ceremony is merely ceremonial. Because the accused's first marriage had been validly dissolved by talaq, which entitled her to remarry, the RTC could not try her for bigamy and the Information was quashed. At the very least, the criminal court should have suspended proceedings until the validity and dissolution of the prior Muslim marriage were litigated before the Shari'a court.
Bigamy; Muslim Conversion No Defense Where Marriages Not Solemnized Under P.D. 1083
Held that a man who claims to have converted to Islam cannot escape liability for bigamy where neither of his marriages was solemnized in accordance with the Code of Muslim Personal Laws. Under Art. 13(2) of P.D. 1083, a marriage between a Muslim and a non-Muslim not solemnized under Muslim law is governed by the Family Code, so the Revised Penal Code on bigamy applies regardless of his professed religion. The accused also cannot attack the validity of his second marriage to escape criminal liability.
The 120+30-day periods for input VAT refund claims are mandatory and jurisdictional; the only exception covers premature judicial claims filed while BIR Ruling No. DA-489-03 was in force (10 Dec 2003 to 6 Oct 2010)
A taxpayer must file the administrative claim for an input VAT refund within two years after the close of the taxable quarter under Section 112(A). It must then wait for the CIR's decision or for the 120-day period to lapse, and appeal to the CTA within 30 days after that. The 30-day appeal need not fall within the two-year period. Section 229's two-year rule does not govern 'excess' input VAT. Taxpayers who filed prematurely in reliance on BIR Ruling No. DA-489-03, a general interpretative rule, are protected by equitable estoppel under Section 246, from its issuance on 10 December 2003 until Aichi on 6 October 2010.
Solidary Liability in Labor-Only Contracting
The principal and a labor-only contractor are solidarily liable to the workers. Because the liability is solidary, the releases and quitclaims the workers executed in favor of the contractor also benefited the principal under Article 1217 of the Civil Code, and extinguished their claims against it.
Legislators may not take part in budget execution after the budget is enacted; the PDAF and similar pork barrel laws are unconstitutional
Declared the 2013 PDAF Article and all similar Congressional Pork Barrel provisions and informal practices unconstitutional. Post-enactment roles for legislators in identifying projects, releasing funds and realigning them violate separation of powers. Personal lump-sum allocations let individual legislators appropriate, violating non-delegability. The system also defeated the President's item veto, diluted congressional oversight and subverted local autonomy. The Court also struck down, as undue delegations, the phrases letting the President use the Malampaya Funds 'for such other purposes as may be hereafter directed by the President' and the Presidential Social Fund 'to finance the priority infrastructure development projects'. The ruling is prospective.
Rule 108 May Correct Substantial Entries Through an Adversary Proceeding; Cancelling a Forged Marriage Record Is Not a Declaration of Nullity
Even substantial errors in the civil registry may be corrected under Rule 108 if its requirements are followed and the proceeding is adversarial. A woman whose identity was used in a marriage she never contracted may have the wife entries of the marriage certificate cancelled under Rule 108. This does not circumvent Fujiki v. Marinay, because there was no marriage to declare void.
Cybercrime Prevention Act — Online Libel, Real-Time Traffic Data and Takedown
Upheld online libel under Section 4(c)(4) of R.A. 10175 only as to the original author of a post, not as to those who merely receive and react to it. Struck down Section 12 (real-time collection of traffic data 'with due cause'), which the Court likened to a general search warrant, and Section 19 (DOJ blocking of computer data without judicial intervention). It also held that prosecuting the same online libel under both the Revised Penal Code and R.A. 10175 violates double jeopardy.
Res ipsa loquitur does not apply where a rare bad outcome is all that is shown; medical negligence, even in a criminal case, generally requires expert proof of the standard of care and causation
Acquitted an anesthesiologist of reckless imprudence resulting in serious physical injuries. Res ipsa loquitur did not apply because a rare bad outcome during surgery does not by itself show negligence. With no expert testimony on the standard of care, and with the prosecution's own witness admitting that other factors could have caused the hypoxia, guilt was not proved beyond reasonable doubt, and no civil liability could be imposed on speculation. The Court also held void the lower courts' award of joint and several liability against Ospital ng Maynila, which was never charged or made a party.
Shari'a District Court Jurisdiction over Real Actions Requires That All Parties Be Muslims
Held that under Art. 143(2)(b) of the Code of Muslim Personal Laws, the Shari'a District Court's jurisdiction over real actions, concurrent with the regular courts, exists only when all the parties are Muslims. An action by a Muslim to recover land from a non-Muslim must be filed in the regular courts, and a judgment rendered without that jurisdiction is void even if the Shari'a court applied the Civil Code, the defendant was served summons, and the objection was raised only after judgment.
Transfer of Appropriations and Savings — Section 25(5), Article VI (DAP)
Declared unconstitutional specific acts and practices under the Disbursement Acceleration Program: declaring unobligated allotments and unreleased appropriations as savings before year-end, cross-border transfers of Executive savings to other branches and constitutional bodies, and funding projects with no appropriation in the GAA (this third declaration was deleted on reconsideration on February 3, 2015). The Court held the DAP itself was an executive policy, not an appropriation, and applied the operative fact doctrine to DAP-funded projects.
Habeas Data Is Not Limited to Killings and Disappearances; a Reasonable Expectation of Privacy on Facebook Requires Use of Privacy Tools
The writ of habeas data is an independent remedy to protect informational privacy, not confined to extralegal killings and enforced disappearances, and it may issue against anyone who gathers, collects or stores data even if not in that business. But a social media user has a protected expectation of privacy only in posts whose visibility the user has limited through privacy tools; a "Friends" setting alone does not make a post private, and the claimant must prove the restriction.
Successive Fixed-Term Contracts / Regular Employment
Held that the employer bears the burden of proving that a person it pays is an independent contractor. A news correspondent/producer whose work was necessary and desirable to the network, and whose one-year contracts were renewed each year, was a regular employee even though she had a fixed-term contract. Non-renewal of her contract after she disclosed her lung cancer was an illegal dismissal: disease is a ground for termination under Art. 284 [now Art. 299] only if, among other things, a competent public health authority certifies that it cannot be cured within six months even with proper medical treatment.
Actual owner-employer not exempt from quasi-delict liability because another is the registered owner
Held that a bus company that actually owned and operated the bus and employed the negligent driver cannot escape liability under Articles 2176 and 2180 of the Civil Code by pointing to the registered owner; the registered owner rule protects the public and is not a shield for the actual owner. Both the owner of record and the actual operator may be held jointly and severally liable with the driver, the registered owner having a right to be indemnified by the actual owner.
Bail May Be Granted on Humanitarian Grounds, Independently of the Merits of the Charge, Where Continued Detention Is Clearly Shown to Endanger the Health or Life of the Accused
The divided en banc ruling (8–4) that released a senator over 90 years old and charged with plunder without any hearing on whether the evidence of his guilt was strong. The Court left open whether his age and voluntary surrender could lower the imposable penalty and so make bail a matter of right. It held that that question was factual and for the Sandiganbayan. It granted bail instead because the primary purpose of bail is to secure the appearance of the accused, he was not a flight risk, and his fragile health made continued detention dangerous, following Dela Rama v. People's Court. Leonen, J., joined by the Chief Justice and two others, dissented sharply. The People's motion for reconsideration was denied on July 12, 2016. Read it as an exceptional ruling rather than the ordinary rule on bail in reclusion perpetua cases, which still requires a hearing on the strength of the evidence (Rule 114, Sections 7 and 8).
NCIP jurisdiction under IPRA Sec. 66 covers only disputes between members of the same ICC/IP; the regular courts otherwise have jurisdiction, subject to exceptions under Secs. 52, 54 and 62
Held that under IPRA Sec. 66 the NCIP has jurisdiction over claims and disputes involving rights of ICCs/IPs only when they arise between parties belonging to the same ICC/IP. Where the parties belong to different ICCs/IPs, or one party is not an IP, the proper courts have jurisdiction, except in cases under Secs. 52 and 62 (delineation conflicts) and Sec. 54 (fraudulent claims). The Court also struck down NCIP rules that expanded its jurisdiction beyond the statute.
Limits of NCIP's Administrative Jurisdiction
Held that Section 66 of the IPRA gives the NCIP jurisdiction only over claims and disputes involving rights of ICCs/IPs where both parties are ICCs/IPs and have exhausted customary-law remedies. Disputes with non-IPs remain within the general jurisdiction of the regular courts. The Court declared void Section 1 of NCIP Administrative Circular No. 1, series of 2014, which classified the Regional Hearing Officer's jurisdiction as original and exclusive, because an agency cannot expand by rule the jurisdiction the law confers.
Defective waivers of the statute of limitations held valid by exception where both parties were at fault and the taxpayer was estopped
As a rule, a waiver that does not comply with RMO 20-90 and RDAO 05-01 does not extend the three-year period to assess. In this case the Court nonetheless upheld five defective waivers as an exception, for several reasons. Both parties were in pari delicto, and public policy favors tax collection. The taxpayer did not come with clean hands. It was estopped after benefiting from the waivers it had itself executed, and the BIR's gross negligence could be addressed through administrative sanctions.
Ancillary Jurisdiction of Shari'a Circuit Court over Custody in Divorce Cases; Due Process in Custody Awards
Held that although Art. 143(1)(a) of P.D. 1083 gives the Shari'a District Court exclusive original jurisdiction over custody cases, the Shari'a Circuit Court has ancillary jurisdiction to decide custody as an incident of a divorce (talaq) case within its jurisdiction under Art. 155. A case in which custody is the main cause of action still belongs to the District Court. The Court voided the custody award because it was granted on a motion without notice of hearing and without stating its factual and legal basis, and it held that disqualification for apostasy under the Muslim Code concerns inheritance, not custody.
COMELEC cannot decide a candidate's qualifications in a COC-cancellation case; foundlings are presumed natural-born; residence may be counted from actual return
The Court annulled the COMELEC resolutions cancelling Grace Poe's certificate of candidacy for President and declared her qualified to run in 2016. The ponencia held that foundlings are, as a class, natural-born citizens, relying on the 1935 framers' intent, a presumption of Filipino parentage backed by statistics, and generally accepted principles of international law. It also held that her residence could be counted from her return on 24 May 2005. The vote on the judgment was 9-6, and the dissents point out that fewer than a majority joined the ruling on natural-born status.
NCIP jurisdiction is concurrent with regular courts, but the body that first takes cognizance excludes the others
Reaffirmed Lim v. Gamosa: the NCIP does not have original and exclusive jurisdiction over disputes involving ICCs/IPs, and its limited jurisdiction is concurrent with that of the regular courts. Because the petitioner first brought the ancestral land dispute to the NCIP Regional Hearing Office, that office acquired jurisdiction to the exclusion of the MCTC. His later forcible entry suit was barred by estoppel and by forum shopping.
No Letter of Authority, void assessment; a Letter Notice is not a substitute
An assessment issued without a Letter of Authority is void, because Section 6 of the NIRC requires authority from the Commissioner or a duly authorized representative before any examination of a taxpayer. A Letter Notice issued under the RELIEF system is no substitute. The Court also held that the 80% of an HMO's membership fees earmarked for its members' medical utilization is not part of its gross receipts for VAT purposes.
Voluntary Appearance Cures Lack of Summons; Heirs' Liability Limited to Inheritance
Defendants who admitted receiving summons, filed an answer, presented one of themselves as a defense witness and appealed all the way to the Supreme Court cannot later attack the judgment for lack of jurisdiction over their persons; active participation is tantamount to invoking the court's jurisdiction. The Court nonetheless relaxed the immutability of a final judgment to limit the heirs' liability for the monetary awards to the value of their inheritance.
'Ada Must Be Proven as a Fact; No Dismissal Without Pre-Trial and Trial in Shari'a Courts
The existence and applicability of customary law ('ada), like prescription and laches, are questions of fact that must be proven in evidence (Art. 5, P.D. No. 1083) and cannot be resolved by the Supreme Court under Rule 45. A Shari'a District Court that dismissed a land-recovery suit on the pleadings, without pre-trial or trial under the Special Rules of Procedure in Shari'a Courts, committed error, and the case was remanded for trial on the merits.
Foreign Divorce Initiated by the Filipino Spouse (Art. 26(2), Family Code)
Held that Art. 26(2) of the Family Code applies even when the Filipino spouse, not the alien spouse, filed for the divorce abroad: the provision requires only a divorce validly obtained abroad that capacitates the alien spouse to remarry. The divorce decree and the foreign law allowing it must still be proven as facts, so the case was remanded to receive evidence of Japanese divorce law.
The LGUs' just share under Art. X, Sec. 6 is computed on all national taxes, not only national internal revenue taxes
Declared the phrase 'internal revenue' in Section 284 of the Local Government Code (and in Sections 285, 287 and 290) unconstitutional. Section 6, Article X gives LGUs a just share in 'the national taxes', so the base must include all national tax collections, including customs duties and the VAT, excise and documentary stamp taxes collected by the BOC. Only exclusions the Constitution authorizes, such as special-purpose funds and shares from national wealth, may be left out. The ruling is prospective, and the just share must be released automatically without need of annual appropriation.
Primacy of State Criminal Law Over Tribal Resolutions
Held that the IPRA does not take away the courts' jurisdiction over criminal cases involving indigenous peoples. Customary justice systems under Sections 15 and 65 of the IPRA operate only within the community and only as far as they are compatible with the national legal system. A tribal court's resolution clearing an accused of rape therefore neither bars prosecution nor creates a right enforceable by mandamus.
Sale proceeds of Metro Manila camp lands under Section 8, RA 7227 (as amended) are exempt from all taxes, including creditable withholding tax
Section 8 of RA 7227, as amended by RA 7917, appropriates the proceeds from BCDA's sale of the listed Metro Manila military camp lands to specific purposes. It provides that those proceeds 'shall not be diminished and, therefore, exempt from all forms of taxes and fees.' The proceeds are public funds, not BCDA income. Section 27(C) of the NIRC, a general law, did not impliedly repeal this special provision, so the creditable withholding tax on the sale had to be refunded.
Trademark resemblance: Holistic Test abandoned, Dominancy Test governs; Nice classification abandoned as a relatedness factor
The Court en banc declared that the Holistic Test for resemblance of marks has been abandoned, because Section 155.1 of the IP Code and its legislative deliberations adopted the Dominancy Test, and it abandoned the use of product or service classification as a factor in determining relatedness of goods. Applying a multifactor test, it rejected Kolin Philippines' application for a stylized 'kolin' mark for televisions and DVD players and held that the 2015 Taiwan Kolin decision was neither res judicata nor controlling precedent.
Psychological Incapacity as Legal Concept
Restated the Molina guidelines and held that psychological incapacity under Art. 36 is a legal, not a medical, concept. The Court abandoned the second Molina guideline: the incapacity need not be a mental illness or personality disorder proven by expert opinion, and ordinary witnesses and the totality of the evidence may establish it. Incurability is understood in a legal rather than a medical sense, and the petitioner must prove the incapacity by clear and convincing evidence.
Dismissal at Plaintiff's Instance Is Without Prejudice; No Res Judicata or Litis Pendentia
A dismissal granted on motion of the plaintiff's counsel after the plaintiff's death, without substitution of heirs, is not void where the heirs themselves did not assail it and even ratified counsel's act; being final, it leaves no pending action for litis pendentia. Not being a dismissal for failure to prosecute under Section 3, Rule 17, and containing no contrary declaration, it is without prejudice and does not bar refiling under res judicata.
Doctrine of corporate opportunity: guidelines for a Section 34 (now Section 33, RCC) claim
The En Banc adopted, from Guth v. Loft as synthesized in Broz, four guidelines a claimant must show for damages under Section 34 of the Corporation Code (now Section 33 of the RCC): the corporation is financially able to exploit the opportunity; the opportunity is within its line of business (the corporations must be shown to be in competition); the corporation has an interest or expectancy in it; and taking it places the fiduciary in a position inimical to his duties. The controlling family's knowledge or tolerance of a director's competing companies is not the two-thirds stockholder ratification that Section 34 requires.
Situs of income: satellite air time fees paid to a nonresident foreign corporation are Philippine-sourced
Satellite air time fees paid to a nonresident foreign corporation were held to be income from Philippine sources, subject to 35% final withholding tax. The service is completed, and the fees accrue, only when the Philippine gateway receives the call routed by the satellite. The Court also applied the TRAIN Law so that deficiency and delinquency interest run together only until December 31, 2017.
No assessment is required to prosecute a tax offense, or to award civil liability for unpaid taxes in the same criminal action before the CTA
The Court affirmed the conviction under Section 255 of the NIRC for willful failure to file a return and to supply correct and accurate information. It held that under Section 7(b)(1) of RA 9282, the civil action for unpaid taxes is deemed filed with the criminal action. This impliedly repealed Section 205's requirement of a final CIR decision, so a formal assessment is no longer a condition for imposing civil liability for taxes in the criminal case. The government must still prove that liability by competent evidence. The Court also clarified how CTA and regular-court jurisdiction interact after RA 11576.
Postponement of Elections and the Right of Suffrage (R.A. 11935)
Declared R.A. 11935, which postponed the December 2022 Barangay and SK elections to October 2023, unconstitutional. The law was mainly meant to realign COMELEC's election budget, an impermissible transfer of appropriations, so it violated substantive due process and the right of suffrage and was enacted with grave abuse of discretion. The Court recognized that Congress has power to postpone barangay elections and laid down guidelines for future postponements. Applying the operative fact doctrine, it let the October 2023 BSKE proceed and allowed incumbents to hold over.
Red-Tagging / Writ of Amparo
The Court declared that red-tagging, vilification, labelling and guilt by association are threats to a person's right to life, liberty or security under Section 1 of the Rule on the Writ of Amparo, which may justify issuing the writ. It reversed the RTC's outright dismissal of an activist's petition and issued the writ, requiring a return and a summary hearing. Whether the privilege of the writ should finally be granted was left to the RTC.
Lawyer's abusive, discriminatory on-air statements; penalty for a previously disbarred lawyer (CPRA Canon VI, Sec. 42)
Applying the CPRA retroactively, the Court found Atty. Gadon guilty of violating Canon II (Propriety) for cursing the late President Aquino on radio, celebrating his death, and falsely claiming he had HIV, which fueled stigma against persons living with HIV. Because Gadon had already been disbarred in A.C. No. 13521, the disbarment could not be imposed again. Under Section 42, Canon VI of the CPRA it was recorded in his personal file, and a PHP 150,000 fine was imposed. The Court also held that complainants need not be real parties-in-interest and that lawyers may be disciplined for conduct in their private life.
GCTA after final conviction covers persons convicted of heinous crimes, recidivists, habitual delinquents and escapees
The Court nullified the 2019 IRR provisions of RA 10592 that barred recidivists, habitual delinquents, escapees and persons convicted of heinous crimes from earning good conduct time allowance (GCTA) while serving sentence after final conviction. Amended Article 97 of the RPC grants GCTA to 'any convicted prisoner' in a penal institution or jail, and the IRR could not narrow that. The statutory exclusion in amended Article 29 still applies to preventive imprisonment: recidivists, habitual delinquents, escapees and persons charged with heinous crimes cannot earn GCTA while detained before final conviction.
Marital Infidelity as VAWC
The Court en banc declared marital infidelity a form of psychological violence punishable under Section 5(i) of RA 9262 where it causes the wife mental or emotional anguish, and limited the intent requirement of Acharon v. People to cases of denied financial support. Reconsideration was denied with finality on 19 August 2025.
COMELEC, not HRET, Jurisdiction to Cancel Party-List Registration
Held that cancelling a party-list group's registration falls within COMELEC's jurisdiction under Article IX-C, Section 2(5) and Section 6 of R.A. 7941, even when the group has a sitting nominee in the House. The HRET's jurisdiction covers only contests over the election, returns and qualifications of Members, and the party-list is not the Member. The Court also held that the action to cancel does not prescribe, and that the four-year COMELEC delay did not violate the right to speedy disposition in this administrative case.
Exact Confiscated Firearm Must Be Presented and Its Integrity Preserved
In prosecutions under R.A. No. 10591, the prosecution must present in court the exact same firearm confiscated from the accused and show its integrity was preserved; a certification that the accused is not a licensed firearm holder is not, by itself, proof beyond reasonable doubt. The Court laid down guidelines on when the firearm must be presented and required that confiscated firearms be marked, photographed, authenticated and preserved.
Boundary disputes between highly urbanized cities must first be jointly referred to their sanggunians (LGC Secs. 118-119); declaratory relief is improper
Held that competing claims by Caloocan and Malabon over portions of Barangays 160 and 161 are a boundary dispute. Under Section 118(d) of the Local Government Code it must first be jointly referred to the two cities' sanggunians, and only afterward brought to the RTC under Section 119. The Court therefore found a direct petition for declaratory relief attacking R.A. 9019 premature and improper, and declined to rule on the law's constitutionality because it was not the lis mota.
Perfection of Employment Contract; Start Date as Suspensive Period, Not Condition
Held that when a job offer is accepted and the agreed start date is a period (a day certain) rather than a condition, the employer-employee relationship already exists and only the demandability of the obligations is deferred. The employer's withdrawal of the accepted offer before the start date for alleged redundancy was treated as a dismissal, and because the redundancy was not proved, the dismissal was illegal.
