Step 1: Understanding the Question:
The question asks to identify the correct statement(s) regarding the legal principles and limitations of delegated legislation under constitutional and administrative law.
Step 2: Key Legal Principles and Approach:
Delegated legislation (subordinate legislation) occurs when the legislature delegates rule-making power to executive authorities.
This power is subject to the constitutional doctrine of separation of powers and the maxim delegatus non potest delegare.
Step 3: Detailed Explanation:
• Analyzing Statement (A) "A delegate cannot further delegate": This reflects the fundamental legal maxim delegatus non potest delegare.
• When the legislature delegates power to a specific executive authority, that authority cannot sub-delegate that power to another body unless the parent statute explicitly authorizes sub-delegation.
• Hence, statement (A) is true.
• Analyzing Statement (B) "Essential legislative functions cannot be delegated": This is the key constitutional limitation established by the Supreme Court of India in the landmark In Re Delhi Laws Act Case (1951).
• The legislature cannot abdicate its power.
• The essential legislative function consists of determining the legislative policy and formalizing it into a rule of conduct.
• Hence, statement (B) is true.
• Analyzing Statement (C) "Ancillary and incidental legislative functions can be delegated": Once the legislature defines the policy and standard in the parent Act, it can delegate the power to fill in the details (ancillary, incidental, and procedural matters) to the executive.
• Hence, statement (C) is true.
• Since statements (A), (B), and (C) are all true, the correct option is (D), "All of the above."
Step 4: Final Answer:
The rules of non-subdelegation, preservation of essential legislative functions, and permissibility of delegating ancillary matters are all true, making Option (D) the correct answer.
