The Act of Free Choice (Indonesian: Penentuan Pendapat Rakyat, PEPERA, Determination of the People’s Opinion) was an election held on August 2, 1969 in which 1,025 men and women selected by the Indonesian military in Western New Guinea voted unanimously in favor of Indonesian control.
Sure, but an audit with high transparency was ordered right after. /rimshot
