paragraph_text: 1973 and 1987 Constitutions
  
  A new Constitution ratified on January 17, 1973, under the rule of Ferdinand Marcos introduced a parliamentary-style government. Marcos instituted himself as prime minister while serving as president in 1978. Marcos later appointed César Virata as prime minister in 1981, although, he was only a figurehead as the government control was still with Marcos.
  
  The 1973 Constitution was in effect until the People Power Revolution of 1986 toppled Marcos's 21-year authoritarian regime and replaced him with Corazon C. Aquino. On March 25, 1986, Aquino issued Proclamation No. 3, s. 1986 or the "freedom constitution" that initially replaced the 1973 Constitution. This provisional constitution was done as Aquino was installed as president through revolutionary means. Proclamation No. 3 abrogated many of the provisions of the then 1973 Constitution, including the provisions associated with the Marcos regime, which gave the president legislative powers, as well as the unicameral legislature called the Batasang Pambansa (literally National Legislature in Filipino). The proclamation retained only parts of the 1973 Constitution that were essential for a return to democratic rule, such as the bill of rights. This constitution was superseded on February 2, 1987, by the present constitution.
