<h1>Election Commission SIR of electoral rolls is legislative, prescribing principles and documentary requirements for voter registration.</h1> The Election Commission's SIR order is legislative in character, prescribing nationwide principles and 11 specified documents (including Aadhaar) required only where linkage to earlier electoral entries up to June 2025 cannot be established. Enumeration forms and pre-filled house-to-house procedures by Booth Level Officers confer probative value, and the EC may determine citizenship solely for registration purposes under its constitutional role, constrained by Articles 324-326 and Section 62 of the Representation of the People Act.
