Tenancy Disputes and Jurisdiction: Courts vs. Agrarian Reform Boards

The Supreme Court recently clarified the dividing line between the jurisdiction of the Department of Agrarian Reform Adjudication Board (DARAB) and that of the DAR Secretary over agrarian matters. In Mercado v. Heirs of De Guzman (G.R. No. 225427, January 26, 2026), the Court ruled that not every case involving agricultural land or an emancipation patent is an agrarian dispute. The case underscores that the existence of a tenancy relationship is the key to determining which forum has authority.

The Facts of the Case

Carmelita Mercado sought the annulment of an Emancipation Patent covering an 8,212-square meter portion of land registered in the name of the Heirs of Serafin De Guzman. Mercado claimed the portion was erroneously included in the title. She relied on a 1994 decision of the Provincial Agrarian Reform Adjudicator (PARAD) ordering the issuance of an emancipation patent in her favor.

The Heirs of De Guzman countered that one of their family members had merely lent the land to Mercado to finance a hospitalization. They argued that no tenancy relationship existed and that Mercado was not a qualified agrarian reform beneficiary.

The Regional Agrarian Reform Adjudicator (RARAD) later ruled against Mercado, holding that the 1994 decision was void for violating the heirs' right to due process. The DARAB, on appeal, set aside both the 1994 and 2001 decisions, ruling that the issue of reallocation was an administrative matter exclusively within the DAR Secretary's jurisdiction. The Court of Appeals reversed, reinstating the 2001 RARAD decision.

The Issue: Who Has Jurisdiction?

The Supreme Court framed the core question as whether the DARAB had jurisdiction over the cancellation of the emancipation patent and the reallocation of the disputed land.

The Court explained that the CARL and the 1994 DARAB Rules distinguish between two concepts:

• Agrarian reform matters — the administrative implementation of the agrarian reform program, which falls under the exclusive jurisdiction of the DAR Secretary.
• Agrarian disputes — controversies relating to tenurial arrangements over agricultural land, which fall under the DARAB's primary and exclusive jurisdiction.

The Ruling: No Tenancy, No DARAB Jurisdiction

The Supreme Court denied Mercado's petition and reinstated the DARAB's September 13, 2012 decision. The Court held that the DARAB had no jurisdiction over the case because no agrarian dispute existed.

To qualify as an agrarian dispute, the following elements of tenancy must concur:

1. The parties are the landowner and the tenant or agricultural lessee;
2. The subject matter is agricultural land;
3. There is consent between the parties to the relationship;
4. The purpose is agricultural production;
5. There is personal cultivation by the tenant; and
6. The harvest is shared between landowner and tenant.

In this case, the parties had no tenurial arrangement. The land was merely lent to finance a hospitalization. There was no agreement on cultivation or sharing of harvests. Consequently, the DARAB had no jurisdiction.

The Court also ruled that the cancellation of an emancipation patent does not automatically fall under DARAB jurisdiction. What matters is whether an agrarian dispute exists. Here, the reallocation of the property and Mercado's qualification as a beneficiary were administrative matters exclusively for the DAR Secretary.

Void Judgments and the Immutability Doctrine

The Court also addressed the doctrine of immutability of judgments. While final judgments are generally unalterable, one recognized exception is a void judgment. A judgment rendered without jurisdiction is void and produces no legal effect. It can never attain finality and may be challenged at any time.

Both the 1994 PARAD decision and the 2001 RARAD decision were void because they resolved the reallocation issue without authority. The DARAB had no jurisdiction to determine Mercado's qualification as a reallocatee or to order the issuance of an emancipation patent without an order of reallocation from the regional director or DAR Secretary.

Practical Takeaways

• Not every case involving agricultural land is an agrarian dispute. The presence of a tenancy relationship is the decisive factor for DARAB jurisdiction.
• Know the proper forum. Cases involving the administrative implementation of agrarian reform — such as beneficiary qualification and reallocation — belong to the DAR Secretary, not the DARAB.
• A void judgment is never final. A decision rendered without jurisdiction can be attacked at any time, regardless of the lapse of the appeal period.
• Document the tenurial arrangement. Parties claiming DARAB jurisdiction should be prepared to prove the elements of tenancy, including consent, cultivation, and sharing of harvests.
• Seek early jurisdictional assessment. Determining the correct forum at the outset can save time, costs, and the risk of a void judgment.
