Republic Act No. 6657, or the Comprehensive Agrarian Reform Law, was signed into law by then President Corazon Aquino, placing her family-owned Hacienda Luisita in Tarlac province under land reform. The program was supposed to end in 1999 after 10 years of implementation, but it failed to meet its target. The latest extension was named Comprehensive Agrarian Reform Program Extension with Reforms, which was passed in 2008.
