The Order inter alia provided that the new High Court of West Pakistan would have such Original, Appellate and other jurisdiction and such powers and authority in respect of the territories included in the Province of West Pakistan as the High Court of Judicature at Lahore had immediately before the commencement of that Order.
As previously provided in the Government of India Act 1935, the new Constitution declared the two Provincial High Courts to be Courts of Record and provided for the appointment of permanent and acting judges by the President of Pakistan (instead of the Governor-General), for their holding of the office during good behaviour and for their retirement at the age of 60.
The bifurcation previously created between barristers and pleaders was removed and both were grouped into one compartment for eligibility, namely, advocates or defendants having at least ten years' standing in both or either of High Courts.
The qualifying period of five years service previously laid down for persons holding judicial officers in British India not inferior to that of a subordinated Judge, or judge of a Small Cause Court, was raised to ten, but the enumeration describing the two particular types of judicial offices to be held was removed.
The two High Courts were given power, throughout the territories in which they exercised jurisdiction, to issue to any person or authority (including the government directions, orders or writs (including writs in the nature of habeas corpus, mandamus, prohibition, quo warranto and certiorari) for the enforcement of all or any of the Fundamental Rights contained in Part II of the Constitution and for any other purpose generally.
