A senatorial election was held on November 8, 1971 in the Philippines . The opposition Liberal Party won five seats in the Philippine Senate while three seats were won by the Nacionalista Party , the administration party; this was seen as a consequence of the Plaza Miranda bombing on August 21, 1971, which wounded all of the Liberal Party's candidates and almost took the lives of John Henry Osmeña and Jovito Salonga . Their terms as senators were cut short as a result of the declaration of martial law by President Ferdinand Marcos on September 23, 1972.
Due to the ratification of a new constitution in 1973, the Senate was abolished and the unicameral parliamentary Batasang Pambansa was instituted. In 1987, a new constitution was approved that reverted to the presidential and bicameral legislative system. This means that this would be the last election for the Senate until the 1987 election .
