G.R. No. L-17590 and L-17627; November 29, 1962
PATRICIO MAGTIBAY, petitioner, vs. HON. FEDERICO C. ALIKPALA, ET AL., respondents. TEODORA O. JULIANO, petitioner, vs. THE COURT OF AGRARIAN RELATIONS, ET AL., respondents.

FACTS

Patricio Magtibay, a share tenant on rice land owned by Teodora O. Juliano, invoked his right under Section 14 of Republic Act No. 1199 (Agricultural Tenancy Act) by notifying Juliano on May 5, 1960, of his election to convert their share tenancy to a leasehold. Juliano refused, questioning the constitutionality of that provision. On May 25, 1960, Juliano filed a petition for declaratory relief in the Court of First Instance (CFI) of Laguna (Civil Case No. B-252) seeking to declare Section 14 unconstitutional. Subsequently, on June 6, 1960, Magtibay filed a petition with the Court of Agrarian Relations (CAR Case No. 383) to compel the conversion and fix the lease rental.
Magtibay moved to dismiss the CFI declaratory relief case, arguing the CFI lacked jurisdiction because a breach had already occurred and the constitutional issue was merely incidental to the tenancy dispute pending before the CAR, which had exclusive jurisdiction. The CFI denied his motion. Meanwhile, in the CAR case, Juliano moved to suspend proceedings pending the CFI’s resolution of the constitutional question. The CAR denied her motion. Both parties elevated their cases via certiorari to the Supreme Court.

ISSUE

The primary issue is whether the Court of First Instance has jurisdiction over the declaratory relief action challenging the constitutionality of a tenancy law provision when a concrete tenancy dispute involving the same parties and the same legal provision is already pending before the Court of Agrarian Relations.

RULING

The Supreme Court granted Magtibay’s petition (G.R. No. L-17590) and denied Juliano’s petition (G.R. No. L-17627). The Court held that the CFI acted without jurisdiction in taking cognizance of the declaratory relief action. Jurisdiction over tenancy disputes, including the determination of rights under the Tenancy Act, is vested exclusively in the Court of Agrarian Relations by Republic Act No. 1267 . The constitutional question raised by the landowner is incidental to the enforcement of Magtibay’s statutory right to convert the tenancy relationship. Since a concrete controversy existed—Magtibay’s exercise of his right and Juliano’s refusal—the case fell within the CAR’s exclusive domain.
The Court emphasized that the CAR is fully competent to rule on the constitutionality of Section 14 as a preliminary matter in deciding the tenancy case. If the CAR finds the provision constitutional, it can proceed to adjudicate the factual issues (e.g., effective date of conversion, rental rate). If the provision is held unconstitutional, the landowner can elevate that issue to the Supreme Court for final determination. This procedure avoids delay and aligns with the statutory mandate for the CAR to settle tenancy disputes expeditiously. The CFI’s assumption of jurisdiction would undermine the CAR’s exclusive authority and create an untenable situation where two courts could render conflicting decisions on the same core dispute. The preliminary injunctions were made permanent in G.R. No. L-17590 and dissolved in G.R. No. L-17627.
