K.R. Periakaruppan, a former Minister from the Dravida Munnetra Kazhagam (DMK), has filed a writ petition in the Madras High Court, alleging that the existence of two constituencies named 'Tirupattur' in Tamil Nadu led to his loss in the 2026 elections by just one vote. He contends that a postal vote cast in his favor was mistakenly sent to the Tirupattur constituency in Tirupattur district instead of the one in Sivaganga district, where he was contesting. This misdirection resulted in him losing to R. Seenivasa Sethupathy of the Tamilaga Vettri Kazhagam (TVK). The court was informed that if the postal vote had been correctly redirected, it would have resulted in a tie, which would have necessitated a draw to determine the winner. The TVK's legal representatives argued that Periakaruppan should have pursued an election petition rather than a writ petition, claiming the Returning Officer could not be compelled to act post-result declaration. The court has adjourned the case for further submissions from the Election Commission of India.
