In this article, I will make a comparative analysis of the constitutions of Pakistan promulgated at different times.


Since independence, Pakistan has witnessed three constitutions including the 1973 constitution which still is in action as law of the land. The first constitution was promulgated in 1956, the second in 1962, whereas the third and current constitution in 1973.  As per the date of their promulgation, they are called the 1956 constitution, the 1962 constitution, and the 1973 Constitution respectively.

The 1956 Constitution lasted only for two years as then-president Iskandar Mirza abrogated it by imposing the first Martial Law in the country. After four years of his rule, Field Marshal Ayub Khan introduced the 1962 Constitution which remained enforced as long as Ayub was in power. 

When Bhutto came to power in 1971, his government promulgated the 1973 constitution with the complete consent of the opposition parties in the parliament. Despite military coups and a number of amendments by military rulers, the 1973 constitution stills act as the constitution of Pakistan.
