Jose Cojuangco died on 21 August 1976 , five years from the day of the Plaza Miranda bombing . On 7 May 1980 , the government filed a case against Tarlac Development Corporation , or TADECO ( a Cojuangco company ) before the Manila Regional Trial Court ( RTC ) . The case ( Republic of the Philippines vs. TADECO , Civil Case No. 131654 , Manila Regional Trial Court , Branch XLIII ) sought the surrender of the hacienda to the Ministry of Agrarian Reform in order to properly distribute the land to the qualified farm workers . The Cojuangcos responded to the case saying that there were no such tenants or farm workers qualified to receive such land . This was during the same time that Ninoy Aquino and his family were to leave for exile in the United States . At the time , the anti-Marcos block portrayed this lawsuit as an attack on the Aquino family by the Marcoses , while the farmers viewed it as the government taking action to help them
