SPOUSES SOLLER vs. HON. ROGELIO SINGSON G.R. NO. 215547 | FEBRUARY 3, 2020 REYES, J. JR., J. ISSUE: Whether or not the RTC has jurisdiction over the subject matter of the case. RULING: Yes. The SC cited Section 3 of R.A. No. 8975 which vested jurisdiction to the Supreme Court to issue any injunction against the government in order to restrain, prohibit or compel a certain act. In the case of Philco Aero vs. Sec. Tugade, the Court ruled that the prohibition covers only temporary or preliminary restraining orders or writs but it does not include decisions on the merits granting permanent injunctions. A complaint for injunction is within the jurisdiction of the RTC. This is because the RTC has jurisdiction over all civil cases in which the subject matter of the litigation is incapable of pecuniary estimation, pursuant to Section 19 of B.P. 129, and as provided by jurisprudence, a complaint for injunction is one which is incapable of pecuniary estimation. The allegations and the prayer of the petitioners in this case was to prevent or prohibit the elevation project, thus, such is an action for injunction and therefore within the jurisdiction of the RTC. A provisional or ancillary remedy of preliminary injunction is different from the principal action for injunction because the provisional or ancillary remedy of preliminary injunction cannot exist only as part or an incident of an independent action or proceeding. In this case, the complaint is for injunction with a prayer for the issuance of a Temporary Restraining Order. What is controlling in determining whether the RTC has jurisdiction or not is the principal action and not the ancillary remedy which is merely incidental to the principal action.
