Constitutional Features: Indian Judiciary

The question asks to identify a feature of the Indian Constitution that relates specifically to the 'Indian Judiciary'. Let's analyze the options:

• Option 1: Supremacy of judiciary - While the Indian judiciary has significant powers (like judicial review), its 'supremacy' isn't explicitly stated as a standalone feature in the same way as other principles. It's more a consequence of its constitutional role.
• Option 2: Judicial independence - This is a fundamental principle ensuring the judiciary can function impartially, without influence from the executive or legislature. The Indian Constitution includes various provisions (like security of tenure, fixed service conditions for judges) to protect this independence. This is a core feature directly related to the functioning of the Indian Judiciary.
• Option 3: Each state has its own high court - This describes the structure of the high courts within the Indian judicial system. While related to the judiciary, it's an organizational aspect rather than a fundamental principle of how the judiciary operates.
• Option 4: Judges of high courts are elected - This statement is factually incorrect for the Indian judicial system. Judges of the High Courts and the Supreme Court are appointed, not elected.

Key Rationale

Judicial independence is crucial for the Indian Judiciary to perform its role effectively, uphold the rule of law, and protect citizens' fundamental rights. The Constitution ensures this independence through specific provisions, making it a key constitutional feature directly related to the judiciary.

Therefore, 'Judicial independence' is the most accurate answer.
