Over whom does a High Court's supervisory power apply?

Correct answer: Over subordinate courts in its state

Correct answer: A, the subordinate courts in its state. A High Court is the highest court at the state level, and its supervisory jurisdiction helps it oversee the functioning of courts below it. This power can concern the proper administration of justice and the observance of legal procedure; it does not mean that the High Court controls every institution in the state. Option A is correct because subordinate courts are the courts over which the High Court has supervisory authority. Option B is wrong because Parliament is a Union legislative institution, not a subordinate court under a High Court. Option C is wrong because Rashtrapati Bhavan is the official residence and office of the President, not a court. Option D is wrong because party manifestos are political documents and are not subordinate courts. Memory cue: High Court supervises courts below it, not Parliament or political parties.
