Mumbai, Feb 6 (IANS): Terming a Delhi court's dismissal of his petition against Home Minister P. Chidambaram in the 2G case as "wrong", Janata Party chief Subramanian Swamy Sunday said he would soon prove the decision wrong in the Supreme Court.

He also claimed Pakistan's Inter-Services Intelligence (ISI) had dossiers on black money stashed away by Indian ministers in foreign banks.

"Prima facie, I established a case against Chidambaram and even the court agreed. I wanted the court to summon him to establish his criminality and cross-examine him as to why he agreed to the 2001 pricing (for airwaves) and share dilution of companies," Swamy said while speaking at the second anniversary lecture of Moneylife Foundation, a not for profit organisation.

Swamy said that he will soon move the Supreme Court against Chidambaram.

He questioned as to why Chidambaram's role was not being probed in the case. "If A. Raja is criminally liable, why can't Chidambaram's role be probed," he asked.

"Conviction proceedings cannot be brought at trial stage. The judge acted on a wrong basis," he alleged.

Swamy also slammed several ministers including Communications Minister Kapil Sibal, as also Prime Minister Manmohan Singh and Congress president Sonia Gandhi.

Taking a dig at the prime minister, Swamy said that Manmohan Singh was weak. He also compared Gandhi to a ringmaster with a whiplash and Manmohan Singh to a lion.

"In Hindi, Singh means a lion," he said, in a lighter vein.

He said that Pakistan's ISI had dossiers on black money stashed away by Indian ministers abroad. "The ISI knows which minister has how much money in which account in a foreign bank," he said.
