The 1997 Rules of Civil Procedure

Section 1

Where an answer fails to tender an issue, or otherwise admits the material allegations of the adverse party’s pleading, the court may, on motion of that party, direct judgment on such pleading. However, in actions for declaration of nullity or annulment of marriage or for legal separation, the material facts alleged in the complaint shall always be proved. (1)

Section 2

The court may motu proprio or on motion render judgment on the pleadings if it is apparent that the answer fails to tender an issue, or otherwise admits the material allegations of the adverse party’s pleadings. Otherwise, the motion shall be subject to the provisions of Rule 15 of these Rules. Any action of the court on a motion for judgment on the pleadings shall not be subject of an appeal or petition for certiorari, prohibition or mandamus. (n)
