Days after J Jayalalithaa took oath as chief minister of Tamil Nadu the opposition DMK on Monday said it has decided to file an appeal against her acquittal in a wealth case by the Karnataka High Court.

The original complainant in the case, BJP leader Subramanian Swamy, had also said he would move the apex court against Jayalalithaa's acquittal.

DMK has been pressing the Karnataka Government to file an appeal against the May 11 verdict of the high court acquitting Jayalalithaa and three others in the disproportionate wealth case, which paved the way for her return as chief minister.  However, since there is no indication yet from Bengaluru about the intention of the Karnataka government the DMK has been forced to approach supreme court with a special leave petition.

"With supreme court having said twice that DMK has the right to participate in this case, I firmly say that the party also will file an appeal in the disproportionate assets case against Jayalalithaa," DMK president M Karunanidhi said in a statement after a meeting of DMK's district secretaries.

Special public prosecutor B V Acharya and Karnataka Advocate General Ravi Varma Kumar had recommended to the Karnataka government to file an appeal against the acquittal.

"We firmly believe that Karnataka government will accept their recommendations and file the appeal," he said.

It was on DMK's prayer in the supreme court that the case was transferred to Bengaluru in 2003 Since then, DMK general secretary K Anbazhagan had impleaded himself in the case. In the latest instance, Anbazhagan had successfully challenged before the apex court the appointment of G Bhavani Singh as SPP in the case by the TN government.

The Supreme Court had on April 27 held as bad in law the appointment of Singh as SPP, following which Karnataka government appointed Acharya in his place.
