A group led by Senator Alan Peter Cayetano files a petition with the Supreme Court seeking to nullify the Senate session held on June 3. The session resulted in the election of Senator Sherwin Gatchalian as Senate President Pro-Tempore, following changes in Senate leadership. According to reports, Cayetano and eight other senators ask the Court to reverse the “revamp” of Senate leadership, arguing that the June 3 session should be declared “null and void.” The petition directs the Supreme Court to treat the proceedings of that date as legally invalid, based on the senators’ challenge to how the leadership election and the subsequent reconfiguration of roles were carried out. The request also frames the issue as a dispute over the legitimacy of the leadership changes adopted during that session. The outlets report that the senators submit the petition as part of their broader effort to have the outcome of the June 3 leadership election overturned through judicial review.
