Answer to Legal GK Question Answer: B) Justice Mohammad Hidayatullah Explanation: Justice Mohammad Hidayatullah, who served as the 11th Chief Justice of India (1968-1970), was also the acting President of India in 1969 after the sudden demise of President Zakir Hussain. During this time, he gave assent to the Bank Nationalisation Act, 1969. When the law was later challenged in Rustom Cavasjee Cooper v. Union of India (1970), Justice Hidayatullah recused himself from the 11-judge bench hearing the case to maintain judicial impartiality. The Supreme Court ultimately ruled that the nationalization of banks violated fundamental rights, particularly Article 19(1)(g) (right to practice any profession or business), marking a significant constitutional and economic ruling in Indian history.
