Today Constitution has acquired an essential role in regulating societies. It is the fundamental law of the state. Its ambit has enlarged to cover all spheres of life and society, encompassing all of its functions – legislative, executive, judicial, etc. This paper discusses Pakistan’s search for a viable constitution, and essential features of the constitution of 1973, including: • Functional Distribution of Powers, Rights and Responsibilities among the Parliament, Executive and Judiciary. • Territorial Classification of the Legislative Powers between the Centre and the Provinces.(The council of common interests, The national finance commission) • Civil-military equation. • Fundamental rights and principles of policy. • Islamic provision of the constitution. Finally, there is the most important question of the sacredness of the Constitution and its very survival. Pakistan’s political system has broken down time and again with the result that the Constitution itself has fallen victim to the ambitions of the extra-political forces. It is this society on which the future of democracy and the supremacy of the Constitution depends. Today, the civil society may not appear to be strong enough to fulfill this difficult task. But one hopes that it will not take too long to rise to the occasion.
