President Diosdado Macapagal signed the Agricultural Land Reform Code, the first comprehensive agrarian reform law in the Philippines. It abolished share tenancy and established leasehold as the tenurial system for rice and corn lands.

President Marcos issued PD 27 decreeing the emancipation of tenant-farmers from the bondage of the soil. It covered all tenanted rice and corn lands, transferring ownership to farmer-beneficiaries regardless of tenurial arrangement.

President Aquino issued EO 229 providing the mechanism for implementing the CARP mandate under the 1987 Constitution. It expanded coverage beyond rice and corn to all agricultural lands including private and public lands.

Congress enacted the Comprehensive Agrarian Reform Law (CARL) institutionalizing the redistribution of all agricultural lands to landless farmers and farmworkers. The law covers all public and private agricultural lands regardless of tenurial arrangement and commodity produced.

The Supreme Court upheld the constitutionality of RA 6657, rejecting challenges that it violated the right to property. The Court held that agrarian reform is a legitimate exercise of police power and the State's power of eminent domain.

The Supreme Court ruled that just compensation must be determined based on the value of the land at the time of taking, not at the time of payment. The Court emphasized that timely payment is part of the constitutional requirement of just compensation.

The Supreme Court held that agricultural lands converted to non-agricultural use before June 15, 1988 (CARP effectivity) are exempt from CARP coverage. This ruling clarified the cut-off date for land conversion exemptions.

The Supreme Court ruled that the five-year prohibition on transfer of awarded lands under Section 27 of RA 6657 applies to all kinds of transfers, including mortgage and execution sales, to prevent frustration of agrarian reform objectives.

Congress extended the land acquisition and distribution component of CARP for another five years and strengthened several provisions. The law closed loopholes on land retention and conversion while increasing funding for support services.

The Supreme Court held that the factors enumerated in Section 17 of RA 6657 for determining just compensation must be mandatory, not merely guides. The DAR and Land Bank must consider all factors in land valuation.

The Supreme Court ordered the distribution of Hacienda Luisita lands to farmer-beneficiaries, invalidating the stock distribution option scheme. The Court held that the SDO failed to transfer ownership of land to farmers and merely gave them shares in the company.

The Supreme Court ruled that while CARP land acquisition and distribution formally ended in 2014, the government's duty to process pending claims and pay just compensation continues until completed.

Congress enacted a law ensuring the continued implementation of agrarian reform by institutionalizing support services to farmer-beneficiaries. The law focuses on productivity, sustainability, and protection of farmer-beneficiaries' rights even after land distribution.
