The top court also said the poll panel can go ahead with its scheduled hearing today itself.
A bench headed by Chief Justice Dipak Misra disposed off the petition filed by TTV Dhinakaran, the deputy general secretary of a faction of the AIADMK party, challenging a Madras High Court order asking the poll panel to decide the election symbol row by October 31.
Mr Dhinakaran had sought at least four months more on some grounds, including that the rival factions have filed affidavits running into 10,000 pages and he needed time to respond to them.
Senior advocate Mukul Rohatgi, appearing for the rival AIADMK faction, claimed Mr Dhinakaran had very few MPs and MLAs in his support and wanted to prolong the proceedings.
The apex court disposed off the petition, saying the poll panel was a high constitutional body which was competent to deal with the question as per the provisions of the law.
