Certification against forum shopping

 Section 5, Rule7 of the Rules of Court provides:

Section 5. Certification against forum shopping. — The plaintiff or principal party shall certify under oath in the complaint or other initiatory pleading asserting a claim for relief, or in a sworn certification annexed thereto and simultaneously filed therewith: (a) that he has not theretofore commenced any action or filed any claim involving the same issues in any court, tribunal or quasi-judicial agency and, to the best of his knowledge, no such other action or claim is pending therein; (b) if there is such other pending action or claim, a complete statement of the present status thereof; and (c) if he should thereafter learn that the same or similar action or claim has been filed or is pending, he shall report that fact within five (5) days therefrom to the court wherein his aforesaid complaint or initiatory pleading has been filed.

Failure to comply with the foregoing requirements shall not be curable by mere amendment of the complaint or other initiatory pleading but shall be cause for the dismissal of the case without prejudice, unless otherwise provided, upon motion and after hearing. The submission of a false certification or non- compliance with any of the undertakings therein shall constitute indirect contempt of court, without prejudice to the corresponding administrative and criminal actions. If the acts of the party or his counsel clearly constitute willful and deliberate forum shopping, the same shall be ground for summary dismissal with prejudice and shall constitute direct contempt, as well as a cause for administrative sanctions.
