Alan Peter Cayetano’s grip on the Senate presidency ended after one month and six days, a span brief enough to place him among the most fleeting tenures the chamber has ever recorded. The Taguig senator now ranks as the second shortest-serving Senate president in Philippine history.
His removal came Wednesday, June 17, during a special session convened on the order of President Ferdinand Marcos Jr. The vote that sealed his exit was made possible when Joel Villanueva crossed over to the rival camp, supplying the 13th senator the bloc had been missing.
That single defection settled a standoff that had dragged on for weeks. The Constitution sets the threshold for the Senate presidency at 13 votes, and once Villanueva joined the opposing side, the majority had the arithmetic it needed. Sherwin Gatchalian was elected to the post shortly after gaveling the session to order. According to Rappler, Cayetano had already surrendered his claim about an hour before proceedings began, after Villanueva personally informed him of his decision to back Gatchalian.
Cayetano had occupied the top post since May 11, when he toppled Vicente Sotto III. His own ascent had hinged on assembling 13 votes — among them the support of Ronald dela Rosa, who surfaced after roughly half a year out of public view. Philstar reported that dela Rosa remains in hiding as he confronts an International Criminal Court arrest warrant tied to crimes against humanity charges.
The benchmark Cayetano now sits behind belongs to Camilo Osias, an educator from La Union who led the chamber for only 13 days in 1952, from April 17 to April 30. That stretch stands as the briefest single term ever held by a Philippine Senate president. Osias would later return for a second short turn the following year before being replaced again.
