MANILA — The Supreme Court has rejected a petition challenging the legitimacy of a June 3 Senate session that led to the ouster of then-Senate President Alan Peter Cayetano, according to an en banc resolution dated August 26.

The high court's dismissal of the petition, which was filed by lawyers Valeriano Loon and Zigfred Lim, has been welcomed by a majority of senators. The decision effectively upholds the legality of the contentious session.

The June 3 gathering proved pivotal in Philippine Senate operations, as it resulted in Cayetano's removal from his position as the chamber's presiding officer. The session had been subject to legal scrutiny regarding its procedural validity.

With the Supreme Court's ruling now final, the Senate can proceed without further legal impediments stemming from the contested session. The decision underscores the judiciary's position on the Senate's authority to conduct its internal proceedings and govern its leadership structure.
