FEDERAL BANK LTD. vs SAGAR THOMAS .

The Supreme Court held that the Federal Bank, being a banking institution performing public duties, qualifies as an 'other authority' under Article 12 of the Constitution of India, making it amenable to writ jurisdiction. The Court affirmed the High Court's decision that the writ petition challenging the dismissal of Sagar Thomas, a Branch Manager, was maintainable despite the bank being a private entity. The judgment emphasized the public interest role of banks and their regulatory oversight by the Reserve Bank of India, thus upholding the maintainability of the writ petition under Article 226.
