A main proposal of Castillo is to elect a Constituent Assembly to replace the constitution inherited from Alberto Fujimori's regime, with Castillo saying "it serves to defend corruption at macro scale."[1][83][84] Castillo has said that, in his efforts to rewrite the Peruvian constitution, he would respect the rule of law by utilizing existing constitutional processes and call for a constitutional referendum to determine whether a constituent assembly should be formed or not; to hold a referendum, Castillo would require a majority vote from congress, which is unlikely and limits his chances of changing the constitution.[85][5][6] All proposed reforms would also have to be approved by congress.[77]
