TMC MP Derek O'Brien has filed an application in the Supreme Court alleging procedural irregularities and arbitrariness in West Bengal's Special Intensive Revision (SIR) of electoral rolls. The petition claims the Election Commission of India (ECI) used informal channels like WhatsApp for instructions, rather than formal written orders, leading to potential disenfranchisement. O'Brien seeks an extension of the January 15 deadline for claims and objections, citing the alleged deletion of millions of names without proper notice and "logical discrepancies" against over a crore voters.
