"The issue is in the domain of the Karnataka government. The Karnataka Cabinet is meeting today or tomorrow to take a decision," Chidambaram said, refusing to comment further on the matter.
The former Union Minister, who hails from Tamil Nadu and is a senior Supreme Court advocate, was asked at the AICC briefing about his view in the matter.
The legal cell of the ruling Congress in Karnataka earlier in the day advised the state government not to file an appeal against the acquittal of Jayalalithaa.
The Karnataka High Court gave a clean chit to Jayalalithaa and three others on May 11, clearing them of "all charges" in the 19-year-old case, helping her to return as Chief Minister of Tamil Nadu.
Advocate General Ravivarma Kumar and Special Public Prosecutor in the case B V Acharya have made public their advice to the state government, as the sole prosecutor, to file an appeal in the apex court.
