'Ada Must Be Proven as a Fact; No Dismissal Without Pre-Trial and Trial in Shari'a Courts

Why it matters

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.

Digest

Facts

Sultan Cawal P. Mangondaya sued Naga Ampaso in the Shari'a District Court (SDC) of Marawi City to recover land in Calanogas, Lanao del Sur, inherited, he said, from his mother. He alleged that Ampaso had cultivated the land since 1989 under the 'ada (customary law) of Calanogas, which lets a person cultivate uncultivated land without the owner's consent but not buy it from a non-owner or sell it. Ampaso sold the land over his objection and, in 2008, refused to return it, even after a local sultanate body ruled for Mangondaya. Ampaso raised lack of jurisdiction and lack of barangay conciliation. He claimed he bought the land in 1987 from its true owner under a deed in Arabic writing and occupied it in good faith; he also invoked laches and called the sultanate ruling a forgery. The SDC treated the answer as a motion to dismiss and, without trial, dismissed the complaint, citing Ampaso's 20-year possession in good faith, prescription and laches, and the 'ada being contrary to law. After receiving conflicting affidavits, it reinstated the complaint, then reversed itself and dismissed the case again in 2012. No pre-trial was ever held. Mangondaya filed a Rule 45 petition.

Issues
  1. 1Whether the Supreme Court, on a Rule 45 petition, may resolve ownership, prescription, laches, and the existence and applicability of the 'ada.
  2. 2Whether the SDC erred in dismissing the complaint without conducting pre-trial and trial.
Ruling

The Court partly granted the petition. On the first issue, no. A Rule 45 petition covers only questions of law, and the issues raised were questions of fact. Ownership requires the reception and evaluation of evidence. Prescription requires factual findings such as when the period began to run. "Laches is evidentiary in nature which could not be established by mere allegations in the pleadings." Whether the 'ada exists and applies is likewise a question of fact. Under Art. 5 of P.D. No. 1083, "Muslim law and 'äda not embodied in this Code shall be proven in evidence as a fact," and no 'ada contrary to the Constitution, the Code, Muslim law, public order, public policy or public interest has legal effect. The parties had submitted conflicting affidavits, and it is not the Supreme Court's function to weigh them. On the second issue, yes. Secs. 6 and 7 of the Special Rules require a pre-trial to define the issues and the submission of witness statements and evidence. When the plaintiff has evidence and the defendant offers a defense, a trial on the merits is necessary. The SDC never held pre-trial despite several settings. Its later orders only summarized the parties' arguments and were "bereft of any discussion on the factual and legal basis for the dismissal." It was error for the SDC to conclude from the pleadings and attachments alone that the petitioner failed to prove his claim, that prescription and laches had set in, and that the 'ada was contrary to law. The assailed orders were set aside, and the case was remanded to the SDC for trial on the merits with utmost dispatch.
