While the tradition of British law culture continues to remain an integral part of the judiciary, the modern existence of the Supreme Court of Pakistan came when the first set of the Constitution of Pakistan was promulgated on 23 March 1956. The ratification of the Constitution of Pakistan reestablished the Supreme Court in 1956, replacing the name "Federal Court" to "Supreme Court", initially had its seat in Karachi where the Sindh High Court exists now. In successive years, the Supreme Court was moved to Lahore High Court until the Supreme Court was permanently moved into its new building constructed in Islamabad in 1964.
