Which one of the following in Indian polity is an essential feature that indicates that it is federal in character?

Answer: A. INDEPENDENCE OF THE JUDICIARY is the feature that signals federal character in the Indian polity. A FEDERAL CONSTITUTION distributes powers between a central authority and constituent units (states), and requires institutional safeguards to maintain that distribution. Key federal features include: (i) WRITTEN CONSTITUTION; (ii) DUAL POLITY; (iii) DIVISION OF POWERS (Seventh Schedule lists); (iv) RIGIDITY of the constitution; and (v) SUPREMACY OF THE CONSTITUTION enforced by AN INDEPENDENT JUDICIARY THAT CAN ARBITRATE between Centre and States. (A) CORRECT. INDEPENDENCE OF THE JUDICIARY is a NECESSARY federal feature. In any federation, disputes between Union and states arise over jurisdiction. Only an INDEPENDENT JUDICIARY can impartially adjudicate such disputes (Article 131 — Supreme Court's original jurisdiction in Centre-state and inter-state disputes). Without an independent judiciary, the centre would in practice dominate the states. Independence of judiciary is therefore not just a feature of constitutionalism in general but the SPECIFIC institutional guarantor of federal balance. Why other options are WRONG: (B) An elected Union Legislature with representatives from constituent units describes a federal Upper House (Rajya Sabha) but ALSO exists in unitary states with regional representation. By itself it does NOT prove a federal character. (C) Inclusion of regional party representatives in the Union Cabinet is a feature of COALITION POLITICS, not federalism. A unitary state can also have regional members in its cabinet. (D) Fundamental Rights are a feature of CONSTITUTIONAL DEMOCRACY (limiting state power), not federalism specifically. Unitary states (e.g., UK with Human Rights Act 1998) have rights protection too. Source: NCERT Class 11 Indian Constitution at Work / D.D.
