A.M. No. MTJ-99-1217 - Radomes vs. Jakosalem

The case involves Almario Bejar (deceased), represented by his heirs, filing a complaint for illegal detainer and damages against Maricel Caluag.
The property in dispute is a residential house constructed of light materials (wood and galvanized iron roof) located on government-owned land at 777 Coral Street, Tondo, Manila.
Historical transactions include:

On December 21, 1981, Almario Bejar sold one-half (1/2) portion of the residential house (measuring twenty-two feet by fifteen feet) to Fernando Mijares for ₱11,000.00.
Subsequently, Almario Bejar became the owner in fee simple of the entire lot, evidenced by Transfer Certificate of Title No. 156220, registered on August 30, 1983.

On September 2, 1991, Fernando Mijares sold his acquired interest in the residential property to Maricel Caluag, who used it as a warehouse for her business.
Almario Bejar later needed the specific portion of his land occupied by the defendant (Caluag) to build a residential house for his family.

On April 9, 2002, Almario Bejar, through counsel, sent a demand letter to Caluag, ordering her to vacate the portion of the property within ten (10) days.
Despite the demand (notably on April 19, 2002), Caluag failed and continues to refuse vacating the property.
Consequently, Almario Bejar filed the complaint for illegal detainer and damages with the Metropolitan Trial Court (MeTC), Branch 12, Manila, docketed as Civil Case No. 173262-CV.

On October 15, 2002, respondent Caluag filed a motion to dismiss, arguing that the MeTC lacked jurisdiction because the case involves issues of ownership.
On February 10, 2003, Caluag supplemented her motion by alleging that the contractual document (aKasulatan ng Bilihan ng Bahay) indicated Almario Bejar had sold both his house and the entire lot, thus implicating issues of title.
On June 16, 2003, the MeTC dismissed Civil Case No. 173262-CV for want of jurisdiction, holding that the matter centers on the enforceability of the subsequent sale rather than illegal detainer.
The Regional Trial Court (RTC), Branch 47, Manila, reversed the MeTC’s dismissal on January 5, 2004, ruling that the main issue was who had the better right to possession and directing the MeTC to hear the case on the merits.
Caluag filed a motion for reconsideration with the RTC which was denied, and she subsequently elevated the issue by filing a petition for review with the Court of Appeals (CA), docketed as CA-G.R. SP No. 85430.
On May 23, 2005, the CA reversed the RTC decision, reinstating the MeTC dismissal order by holding that the allegations did not constitute a case for illegal detainer or forcible entry.
Petitioners then filed a motion for reconsideration before the CA, which was eventually denied, leading to the present petition for review on certiorari under Rule 45 of the 1997 Rules of Civil Procedure.

The central legal question is whether the MeTC has jurisdiction over the complaint filed for illegal detainer.
The dispute involves differentiated remedies for deprivation of property possession: unlawful detainer, suit for forcible entry, accion publiciana, and accion reinvidicatoria.

Does the Metropolitan Trial Court (MeTC), Branch 12, Manila, have jurisdiction over Civil Case No. 173262-CV, given that the complaint is framed as one for illegal detainer?
Is the proper remedy, based on the allegations of the complaint, that of unlawful detainer rather than an issue of title or ownership dispute?

Do the allegations contained in the complaint establish the requisite elements for an illegal detainer action, specifically:

Prior physical possession by the plaintiff?
Deprivation of possession by the defendant through refusal or other wrongful means?

Was the complaint duly filed within the period mandated for unlawful detainer cases—i.e., within one year from the date of the last demand for vacating the premises?
