The final draft of the 1973 (Marcos) Constitution was ratified by Citizens' Assemblies and declared legal by Marcos's Supreme Court. August, Ninoy Aquino was brought to trial before a military tribunal for violating the antisubversion law. Aquino refused to participate in the proceedings.
Ika-31 ng Marso 1975 nang ipagpatuloy ng military tribunal ang paglilitis kay Ninoy. Bilang protesta sa kalagayan niya at ng bansa, nag-hunger strike ang dating Senador, na hindi agad pinansin ni Marcos. Tuloy ang paglilitis; araw-araw ay sa-pilitang dinadala si Ninoy sa korte.
