Pakistan Supreme Court has rejected a government petition seeking review of its Aug 18 ruling clipping the powers of the prime minister to move any legislation, finance or fiscal bill or approving any budgetary or discretionary expenditure without consulting the cabinet. A three-judge bench, headed by Jus'tice Mian Saqib Nisar, yesterday dismissed the petition, saying no grounds had been made requiring intervention of the court. In its review petition, the Finance Ministry had expressed apprehension of a potential constitutional crisis in the wake of the judgement, and said that the principle of collective responsibility had two main aspects, political and legal. <br/><br/>Supreme Court had held that the Prime Minister could not take decisions by himself, or by supplanting or ignoring the cabinet, because the power to take decisions was vested with the federal government, i.e. the cabinet, and unilateral decisions taken by the prime minister would be usurpation of power.
