This document summarizes the process by which the 1987 Philippine Constitution was drafted and ratified after the 1986 People Power Revolution. It describes how President Corazon Aquino issued a temporary constitution called the "Freedom Constitution" and then established a constitutional commission to draft a new constitution. The commission finished its work in October 1986 and the draft was submitted to and ratified by a public referendum in February 1987, with over 76% of voters approving. The new constitution enshrined key principles like sovereignty residing in the people, civilian authority over the military, and separation of powers among the three branches of government.
