The first Essential Truths Booklet released by the Human Rights Violations Memorial Commission (HRVVMC) focuses on the validity of Marcos’ Declaration of Martial Law. It deconstructs and critiques the official justifications given by the administration through Proclamation 1081, and argues that the actual intention for the proclamation was to perpetuate Marcos Sr.’s stay in power. Information prepared for the book is noted to have been a collaborative effort from various academic universities and organizations such as the Bangsamoro Museum, the Presidential Commission on Good Government, and the Bantayog ng mga Bayani Foundation.
