This document compares Pakistan's 1956 and 1962 constitutions. The 1956 constitution introduced a parliamentary form of government, direct elections, and executive power was held by the prime minister. It had three lists of subjects. The 1962 constitution replaced this with a presidential system, allowed indirect elections, gave the president greater power, and introduced Islamic institutions and a referendum system. It provided only two lists of subjects and established a Supreme Judicial Council. Overall, the two constitutions differed significantly in their forms of government and allocation of executive powers.
