Karnataka Chief Minister Siddaramaiah today said the state government is yet to decide on filing an appeal in the Supreme Court against acquittal of Jayalalithaa who is set to stage a comeback as Tamil Nadu chief minister after her acquittal in the disproportionate assets case.

"We have not yet taken any decision; ...law department is examining, they are studying the judgement, we will take a decision after getting inputs from them," Siddaramaiah said.

"We will consider the opinion of Special Public Prosecutor B V Acharya and also the opinion from Law department and the Advocate General and then take a decision," he told reporters in New Delhi. Responding to a question, he said he had not contacted the party (Congress) high command on the issue.

The Karnataka high court gave a clean chit to the AIADMK chief and three others, clearing them of "all charges" in the 19-year-old case on May 11, paving the way for return of Jayalalithaa, who was chosen as legislature party leader by her party in Chennai today, as CM.
