"Karnataka has taken the right step. It is a welcome one," party spokesperson T K S Elangovan told reporters here.
Dravida Munnetra Kazhagam (DMK) President M Karunanidhi, besides other leaders, had been urging Karnataka government to appeal against Jayalalithaa's acquittal.
Tamil Nadu Congress Committee chief E V K S Elangovan lauded his party-led government in Karnataka for "quickly deciding" on approaching the apex court with an appeal before the 90-day deadline.
In his reaction, Pattali Makkal Katchi (PMK) founder S Ramadoss, who had written to Karnataka Chief Minister Siddaramaiah asking his government to appeal against Jayalalithaa's acquittal, said: "albeit a little delayed decision, it is a welcome one."

He said he had been insisting that the verdict had "loopholes".
Ramadoss said if Karnataka government had immediately heeded to his demand, "at least Jayalalithaa becoming Chief Minister could have been avoided" by trying to secure a stay against the High Court verdict.
B V Acharya, who was Special Public Prosecutor (SPP) in the case, should continue in the apex court also since he was aware of the nuances of the case, Ramadoss said.
BJP state unit President Tamizhisai Soundararajan said that since two different verdicts were given in this case-- conviction by lower court and acquittal by High court-, the appeal will give "clarity" to the people of the state.
The Karnataka government, earlier in the day, decided to file an appeal in the Supreme Court against acquittal of Jayalalithaa and three others in the disproportionate assets case.
