Provisional Constitutional Order

Soon after the martial law went into immediate effect in 1977, the constitution of Pakistan was suspended. The first PCO was declared on 24 March 1981 by then-President and chief of army staff General Zia-ul-Haq.[3] It was the first PCO having declared by the President General Muhammad Zia-ul-Haq in the history of the country.[3]

Under this new order, the senior justices of the Supreme Court of Pakistan were asked to take an oath of office under the provisions set by the PCO.[3] On March 1981, President Zia terminated 19 senior justices of the supreme court when they refused to take the oath.[4] Chief Justice Dorab Patel and Senior justice Fakhrauddin Ebrahim declined to take the oath; thus opting for retirement.[4] Senior justice Anwarul Haq also resigned after refusing to take the oath whilst the Senior justice Mushtaq Hussain who was willing to take the oath was not asked to do so.[4]

Senior justices Hussain and Haq had previously approved Bhutto's hanging were reportedly restrained to take an oath under the secretive directives issued by President Zia.[4] All of these Senior justices were asked to tender their resignation, which they did.[4]

Political tensions arising after the border incidents with India that nearly pushed the two countries at the brink of the war, Chairman Joint Chiefs of Staff Committee and chief of army staff General Pervez Musharraf immediately imposed the martial law against government of Prime minister Nawaz Sharif on 12 October 1999.

General Musharraf effectively imposed the state of emergency and suspended the constitution after introducing the provisional order. Nearly, all Senior justices were forcefully required to take an oath of office under this new order, and concerns were raised that this would "erode the independence of the judiciary".[5]

In 2007, another Provisional Constitutional Order was issued by General Pervez Musharraf. The PCO was issued on November 3, 2007 and later amended on November 15, 2007. It was lifted on December 16, 2007.
