The Supreme Court of India, in a recent judgment, has elaborated on the scope and limits of the Election Commission of India's (ECI) powers in relation to the Special Intensive Revision (SIR) of electoral rolls. With reference to the SIR and the statutory framework governing electoral roll preparation in India, consider the following statements:

1. Section 21(3) of the Representation of the People Act, 1950 provides for a 'special revision' of electoral rolls — distinct from the summary or intensive revision under Section 21(2) — and is meant to be carried out in a constituency or part of a constituency, rather than across an entire state.
2. The Supreme Court's May 2026 judgment on the SIR held that the ECI has the authority to determine which documents are required to prove citizenship for electoral roll inclusion, without any need for coordination with the Union Ministry of Home Affairs, which administers the Citizenship Act.
3. Rule 25 of the Registration of Electors Rules, 1960 permits an intensive revision of electoral rolls — which involves house-to-house enumeration — to be conducted just before a general election to a State Legislative Assembly, as it is the most thorough method of ensuring roll accuracy.

Which of the statements given above is/are correct?
