Tenancy Rights vs Ownership Claims: DARAB Jurisdiction in Agrarian Land Disputes

The Supreme Court recently settled a long-running land dispute in Mercado v. Heirs of De Guzman (G.R. No. 225427, January 26, 2026), clarifying the boundaries between the quasi-judicial powers of the Department of Agrarian Reform Adjudication Board (DARAB) and the administrative authority of the DAR Secretary. The ruling is significant for landowners, tenant-beneficiaries, and practitioners because it defines when a controversy over agricultural land qualifies as an "agrarian dispute" — and when it does not.

The Facts of the Case

Carmelita Mercado claimed ownership of an 8,212-square meter portion of a 43,354-square meter property covered by an Emancipation Patent (TCT EP 73307) issued to the Heirs of Serafin De Guzman. Mercado alleged the portion was erroneously included in the patent and sought its cancellation and reallocation in her favor.

The Heirs of De Guzman countered that one of them, Rogelio, had merely lent the portion to Mercado to finance his daughter's hospitalization. They later executed a waiver of rights in her favor due to inability to pay the debt, but they eventually paid the property's amortization to the Land Bank of the Philippines, including the portion Mercado possessed.

A 1994 decision by the Provincial Agrarian Reform Adjudicator (PARAD) ordered the issuance of an emancipation patent to Mercado. However, a 2001 decision by the Regional Agrarian Reform Adjudicator (RARAD) dismissed her complaint, ruling the earlier decision was void for violating the heirs' right to due process. The DARAB then set aside both decisions, holding that reallocation is an administrative matter exclusively within the DAR Secretary's jurisdiction.

The Issue

The sole issue was whether the reinstatement of the 2001 RARAD decision was proper — specifically, whether the DARAB had jurisdiction over the cancellation of the emancipation patent and the reallocation of the disputed portion.

The Court's Ruling

The Supreme Court denied Mercado's petition and reinstated the DARAB's 2012 decision, which had vacated both the 1994 and 2001 rulings.

No agrarian dispute existed. The Court emphasized that a case involving agricultural land does not automatically qualify as an agrarian dispute. For DARAB jurisdiction to attach, there must be a tenurial arrangement between the parties — leasehold, tenancy, or stewardship. Citing Sutton v. Lim, the Court enumerated the requisites of tenancy: (1) the parties are landowner and tenant; (2) the subject is agricultural land; (3) there is consent; (4) the purpose is agricultural production; (5) there is personal cultivation; and (6) harvest is shared.

Here, Mercado and Rogelio had no such arrangement. Rogelio simply lent the land to Mercado to finance his daughter's hospitalization. There was no agreement on cultivation or profit-sharing. Thus, no agrarian dispute existed that the DARAB could adjudicate.

Reallocation is an administrative matter. While the 1994 DARAB Rules of Procedure grant the DARAB jurisdiction over the issuance, correction, and cancellation of emancipation patents, this jurisdiction is confined to agrarian disputes. The identification and selection of CARP beneficiaries — including reallocation — are matters strictly involving the administrative implementation of the agrarian reform program, exclusively cognizable by the DAR Secretary under Section 50 of Republic Act No. 6657 (the Comprehensive Agrarian Reform Law).

Void judgments can be attacked anytime. The Court reaffirmed the immutability of judgments doctrine but recognized its exception for void judgments. A judgment rendered without jurisdiction produces no legal effect and can never attain finality, even after the appeal period lapses. Both the 1994 PARAD decision and the 2001 RARAD decision were void for encroaching on the DAR Secretary's exclusive jurisdiction over reallocation.

Practical Takeaways

• Not every land dispute is an agrarian dispute. DARAB jurisdiction requires a genuine tenurial relationship — tenancy, leasehold, or stewardship — between the parties. A mere loan or lending arrangement over agricultural land does not create one.
• Reallocation and beneficiary qualification are administrative matters. These fall under the DAR Secretary's exclusive jurisdiction, not the DARAB's. Parties seeking reallocation must first obtain an order from the regional director or DAR Secretary.
• Void judgments are never final. A decision rendered without jurisdiction can be challenged at any time, regardless of its apparent finality. This is a critical exception to the immutability of judgments doctrine.
• Check the basis of possession. Parties claiming rights over agricultural land should carefully examine whether their possession rests on a valid tenurial arrangement or merely on a personal transaction like a loan, which carries different legal consequences.
• Follow the proper administrative process. Beneficiaries seeking reallocation or correction of emancipation patents should pursue the administrative remedy before the DAR, not directly before the DARAB.
