The correct option is The Delimitation Commission appointed by the President.
Explanation
Delimitation is the process of fixing limits or boundaries of territorial constituencies in a country to represent changes in the population. In India, this task is entrusted to a statutory body known as the Delimitation Commission, which is constituted by the Central Government under an Act of Parliament.
Detailed Analysis:
- Mandate of the Delimitation Commission: Under Article 82 of the Constitution, the Parliament enacts a Delimitation Act following each Census. The President then appoints a Delimitation Commission. Its primary function is to redraw the boundaries of Lok Sabha and State Assembly constituencies to ensure equitable representation.
- Reservation of Constituencies: The Commission is specifically responsible for determining the number of seats to be reserved for Scheduled Castes (SCs) and Scheduled Tribes (STs) in the House of the People and Legislative Assemblies. It identifies the specific constituencies to be reserved based on the concentration of the SC/ST population in those areas.
- Legal Standing: The orders of the Delimitation Commission have the force of law and cannot be called in question before any court. While the Election Commission of India provides data and assistance (and the Chief Election Commissioner is an ex-officio member), the specific authority to identify and declare reserved seats lies with the Delimitation Commission.
Key Takeaway:
The Delimitation Commission is the independent body empowered to redraw constituency boundaries and identify specific seats for SC and ST reservation based on the latest census data.
