Correct Option
The correct option isWhen they are appointed as a Minister in the state government
Explanation
The Indian Constitution establishes a Parliamentary form of government at both the Centre and the State levels. A defining feature of this system is the fusion of the legislative and executive organs. Members of the Executive (Council of Ministers) are drawn from the Legislature, creating a scenario where specific individuals hold roles in both domains.
Option Analysis
- When they represent more than one constituency is Incorrect: Under the Representation of the People Act, 1951, a person may contest elections from a maximum of two constituencies. However, if elected from both, they must vacate one seat within a prescribed time limit. Therefore, an MLA never represents more than one constituency simultaneously.
- When they are appointed as a Minister in the state government is Correct: An MLA is primarily a member of the Legislative Assembly, responsible for law-making and representing their constituency. When appointed as a Minister, they assume an additional role within the State Executive. This creates a "dual responsibility":
- As an MLA: They participate in legislative debates, ask questions, and represent the interests of their constituency.
- As a Minister: They head a government department, frame policies, and are accountable for the administration of that portfolio.
- When they serve in both the State Assembly and the Parliament is Incorrect: The Constitution prohibits simultaneous membership in both the Parliament and a State Legislature. If a person is elected to both, they must resign from one seat; otherwise, their seat in the Parliament or State Legislature becomes vacant as per specific rules.
- When they are members of a coalition committee is Incorrect: A coalition committee is an informal political mechanism used for coordination between allied parties. Membership in such a committee does not confer a constitutional or official administrative "dual responsibility" in the context of state governance.
Key Takeaway: In a Parliamentary system, a Minister holds a dual role: as a legislator (participating in the law-making process) and as an executive (implementing laws and running the administration).
