Not accurate. Sen Cayetano is no longer SP. With 12 senators present, a quorum was declared out of the base number of 22 since Sens de la Rosa and Estrada are outside the “coercive power” of the Senate (Avelino v Cuenco. GR No 2821).
Hence, we voted to declare all positions vacant, although we could not yet elect a new SP because we lacked the 13 votes required under the Constitution.
