Concept:The Constitution divides legislative subjects between Parliament and State Legislatures. Only Parliament can make laws on matters that are exclusively Union subjects or require constitutional amendments.
Explanation:Parliamentary privileges are special rights for MPs, defined under Article 105 of the Constitution. These fall under the Union domain, so only Parliament can legislate on them. State Legislatures have no authority to define or alter Parliamentary privileges.
The other options can involve State Legislatures in some form:
- A Bill for GST rate change is recommended by the GST Council and then passed by both Parliament and State Legislatures.
- A Bill amending State List entries actually requires a constitutional amendment under Article 368, which is done only by Parliament. However, the question asks which Bill cannot be introduced in a State Legislature – and a Bill to amend the State List is a constitutional amendment bill that only Parliament can introduce. But note: the existing solution states that Bill defining Parliamentary privileges is the correct answer because it cannot be introduced in a State Legislature at all. The other options are either introduced in State Legislature (GST rate change) or are also not introducible? Wait, need to verify: The existing solution says Bill defining Parliamentary privileges is the answer. It also says Bill amending State List entries requires constitutional amendment by Parliament, so also cannot be introduced in State Legislature. But the existing solution specifically chooses B. So we follow that. The explanation given: "Bill defining Parliamentary privileges cannot be introduced in a State Legislature as Parliamentary privileges are enshrined in the Constitution... any further legislation on this falls exclusively under the domain of Parliament." So we stick with that. For clarity, just state that only Parliament can define its privileges. So answer is B.
Answer:Option B – Bill defining Parliamentary privileges.
