The Constitution of 1963 is the fundamental legal document that established the framework for governance in Pakistan. It was enacted on March 1, 1963, and aimed to provide a democratic structure, ensuring the separation of powers among the executive, legislative, and judicial branches. This constitution replaced the previous Constitution of 1956 and introduced a presidential system of government. The 1963 Constitution emphasized the importance of fundamental rights and freedoms for citizens, including freedom of speech, religion, and assembly. It also outlined the roles and responsibilities of various government institutions, promoting accountability and transparency in governance. However, it was later abrogated in 1969, leading to significant political changes in the country.
