Philippines Senate ends June 2026 quorum crisis after chaotic walkouts

On June 3‑4, 2026 the Philippine Senate experienced a dramatic quorum dispute that led to a two‑day stalemate. Senators led by Alan Peter Cayetano staged walkouts, used armed escorts and staged hearings in a bid to prevent a quorum, while a minority of twelve senators remained in session. The dispute hinged on the interpretation of the 1949 Supreme Court ruling in Avelino v. Cuenco, which affirmed that a quorum of twelve members is sufficient to conduct ordinary business.

The June 3 session, attended by twelve senators, was deemed lawful and proceeded to reorganise the chamber. Sherwin Gatchalian was named Acting Senate President‑Pro‑Tempore, Erwin Tulfo took over the Blue Ribbon Committee, and other committees were reshuffled. Subsequent attempts by Cayetano’s allies to reconvene the Senate on June 4 were ruled a performance without legal effect. The episode highlighted tensions between political maneuvering and constitutional procedures within the Philippine legislature.
