Step 1: Understanding the Question:
The question asks for the specific constitutional provision that empowers Parliament to establish Administrative Tribunals to resolve disputes regarding public service conditions.
Step 2: Key Concepts and Approach:
We need to look at Part XIV-A of the Constitution, which was added by the 42nd Amendment Act in 1976.
We must differentiate between the scope of Article 323A and Article 323B.
Step 3: Detailed Explanation:
• Part XIV-A (Tribunals): This part was introduced to reduce the burden on civil courts and expedite disputes concerning public services and other matters.
• Article 323A: This article deals exclusively with Administrative Tribunals (for resolving disputes regarding the recruitment and conditions of service of persons appointed to public services under the Union or States). Thus, Option B is correct.
• Article 323B: This article deals with tribunals for other matters, such as taxation, foreign exchange, land reforms, labor disputes, and foodstuff.
• Exclusivity of 323A: While Article 323B allows both Parliament and State Legislatures to set up tribunals, Article 323A empowers *only* Parliament to set up administrative tribunals.
Step 4: Final Answer:
The provision that specifically deals with setting up Administrative Tribunals is Article 323A. Therefore, Option B is correct.
