Khan joined
non-cooperation movement led by
Gandhi when he was a student. Later he joined the
Indian National Congress and subsequently joined
khilafat movement in 1921 and was arrested and sent to Faridpur jail and later was shifted to Central jail in Dhaka. At that time, he was an ardent follower of
Chittaranjan Das. Khan was elected vice-chairman of Faridpur Municipality. In 1926, he got elected to the Bengal Legislative Assembly from Faridpur. Khan created history when the Constituent Assembly was dismissed by Governor General
Ghulam Mohammad in 1954. Khan challenged the dismissal in the court and the case was filed in the morning of 7 November 1954, by Advocate Manzar-e-Alam. Although the High Court agreed and overturned it, the Federal Court under
Justice Muhammad Munir upheld the dismissal. He had been president of the
Basic Principles Committee set up in 1949. "Justice
A. R. Cornelius was the sole dissenting judge in the landmark judgment handed down by the Supreme Court in the Maulvi Tamizuddin case. That judgment altered the course of politics in Pakistan forever and sealed the fate of democracy. The law had guided him as he had interpreted it and his conscience." The decision to uphold the dismissal of the constituent assembly was to mark the beginning of the overt role of Pakistan's military and civil establishment in Pakistani politics. ==Personal life==
