Philippines
On January 1942, the Philippine Executive Commission or PEC was established as the temporary care-taker government of the Greater Manila area and eventually of the whole Philippines during the Japanese occupation of the country during World War II. The constitution existed until the Liberation of Manila in 1945.
In 1986, President Corazon Aquino dissolved the 1973 Constitution and called for its revision. From February 1986 to February 1987, the Philippines was run under a Provisionary Constitution called "Freedom Constitution" drafted by her executive secretary Joker Arroyo. On September 1986, the Constitutional Commission of 1986 was set up with all members appointed by Aquino. The revised Philippine Constitution was placed into a plebiscite with 76% affirmative votes and was approved.
An unrelated concept is a constitutional commission as stated in the 1987 constitution are governmental bodies that are independent of the three main branches of government. These are the Civil Service Commission, Commission on Audit, and the Commission on Elections. The 1987 constitution does not place upon a constitutional commission the task of amending the constitution: these fall under the Constitutional Convention, the Constituent Assembly and the People's Initiative.
