The Supreme Court has a permanent seat in Islamabad. It also has a number of Branch Registries in 4-5 major cities where cases are heard. It has a number of de jure powers which are outlined in the Constitution. Through several periods of military rule and constitutional suspensions, the court has also established itself as a de facto check on military power.
In addition, it has also been active as a 'watchdog' in checking political corruption and abuse of power in recent times.
