Polling is scheduled for by-elections in Madurantakam and Dharapuram in Tamil Nadu on October 6, according to NDTV.
NDTV also reports that polling is not announced for several other seats—Tiruchi East, Ambasamudram, Viralimalai, Perundurai, and Karur—because election-related cases concerning the returned candidates remain pending. This indicates that the election programme is being staggered based on the status of legal proceedings tied to candidates.
In the reporting, the key difference is not the contest details but the timetable: the seats with bypolls proceed as scheduled for October 6, while others wait for the pending cases to be resolved, affecting when voters in those constituencies will cast ballots.
