Belgica, et.al. vs Ochoa, et.al.; G.R. Nos. 208566/208493/209251; 19 Nov 2013; 710 SCRA 1
Petitioner sought that the annual pork barrel system be declared unconstitutional and null and void for being acts constituting grave abuse of discretion.
Whether or not the 2013 PDAF article and all other Congressional Pork Barrel laws are unconstitutional for violating the constitutional provisions on separation of powers, non-delegability of legislative power and checks and balances.
The post enactment measures including project identification, fund release, and fund realignment are not related to functions of congressional oversight and does not allow legislature to intervene and/or assume duties that properly belong to the sphere of budget execution which belongs to the executive department.
