Veto on Constitutional Grounds

Other constitutions only permit the Head of State to veto a bill due to concerns on its constitutionality. He/She either refers the bill straight to the pertinent organ for judicial review or requests the parliament to reconsider the bill first. If parliament does not meet his/her concerns on the constitutionality of the bill, he/she might refer it to the pertinent court for judicial review. In such a scenario, it is to a lesser extent the executive that limits parliamentary powers but the judiciary through its authority of judicial review. The Head of State might only initiate that process.
