Case Summary (G.R. No. 157866)

Applicable Constitutional and Legal Provisions

Reviewed under the 1987 Constitution. Batas Pambansa Blg. 129, Sections 17 and 18, govern the territorial authority of RTC branches. Rule 63 of the Rules of Court exclusively defines declaratory relief. The law of the case doctrine and rules on certiorari, prohibition, and writs of execution are also applied.

Background Facts

On January 31, 1997, Banaag filed an ejectment suit before the Metropolitan Trial Court (MeTC) Branch 49, Caloocan City, alleging that petitioners built and occupied houses without his consent. Petitioners counterclaimed occupancy rights since 1978 under a Certificate of Occupancy issued by Pinagkamaligan Indo-Agro Development Corporation (PIADECO).

Procedural History

Petitioners moved (July 1997) to suspend proceedings, relying on a preliminary injunction issued by RTC, Quezon City (November 10, 1997), but the MeTC (August 7, 1997) held it territorially inapplicable. The MeTC rendered judgment for Banaag (October 5, 1999). The RTC (November 16, 2000) and the Court of Appeals (April 25, 2002) affirmed. Execution pending appeal was granted (RTC order, September 12, 2001), and a writ of execution issued (September 27, 2001). Petitioners’ motion to suspend execution was denied (February 5, 2002; February 14, 2003). Execution was implemented March 5, 2003.

Issue of Territorial Enforceability of Injunction

Petitioners asserted the Quezon City RTC injunction should bind the Caloocan RTC. Under B.P. 129, Sec. 17 grants regional jurisdiction but Sec. 18 limits enforceability to the branch’s defined territorial area. The Court of Appeals and the RTC correctly held that an injunction does not extend beyond the issuing court’s territorial jurisdiction.

Application of the Law of the Case Doctrine

The binding effect of the Quezon City injunction was finally determined by the Court of Appeals decision (CA-G.R. SP No. 65076), which became final and executory on April 25, 2002. Under the law of the case doctrine, that ruling remains conclusive between the same parties on unchanged facts, precluding petitioners from relitigating the issue.

Issuance of Writ of Execution

Once a judgment is final and executory, the presiding judge must issue a writ of execution unless subsequent events
