Isidoro Yboleon v. Pedro Ma. Sison

Summary

This certiorari case involves a challenge to a trial judge's authority to set aside a compromise judgment. Spouses Isidoro and Graciana Yboleon, along with an insurance company, entered into a judicial compromise settling disputes over fire insurance proceeds and property ownership. After the court approved the compromise and rendered judgment, the wife sought to modify the agreement claiming misunderstanding of legal terms. The trial judge set aside part of the judgment without proper legal grounds. The Supreme Court granted certiorari, holding that judges cannot unilaterally modify or set aside compromise judgments without consent of all parties or evidence of vitiating factors under Civil Code Article 1817. The decision establishes important precedent on the finality and sanctity of judicial compromise agreements, emphasizing that courts lack jurisdiction to alter such judgments based merely on alleged misunderstanding of terms.
