While sources in the State Election Commission said they are likely to file an appeal against the order of the single judge who cancelled the local body elections yesterday, DMK filed the caveat on the matter.
As a consequence of the caveat, if and when the appeal is filed against yesterday's high court order that cancelled the polls, DMK is to be given notice before any direction or order is passed on the appeal.
It had directed the SEC to issue a fresh notification for holding local body elections and complete the poll process before December 31 on a writ plea filed by DMK leader and Rajya Sabha member R S Barathy.
In its petition, DMK had sought adequate reservation to the Scheduled Tribes, and necessary rotation of seats in all the posts as mandated in the Constitution.
