One of the most pressing tasks for the new government of Pakistan after the Bangladesh Liberation War was to draft a new constitution. When martial law was finally lifted, the Assembly was summoned in April 1972 on the basis of the 1970 election result in the former west Pakistan region. A committee was set up from a cross-section of politicians from different parties. There were disagreements within the committee to whether the new constitution should bring in parliamentary rule or a presidential system of government. There were also differing views over the question of provincial autonomy. It took the constitutional committee eight months before it submitted its report on 10th April 1973.
