This document discusses past attempts at charter change in the Philippines and reasons they failed. It notes that almost every administration since martial law has proposed charter change. Past efforts failed because they were seen as ways for presidents to extend their terms rather than due to a lack of merit in the proposed amendments. Specific failed attempts discussed include those under President Erap, Gloria Arroyo, and a PDP-Laban proposal. Skepticism of charter change comes from the misuse of constitutional amendments under Marcos.
