Mumbai: Janata Party president Subramanian Swamy on Sunday termed as "wrong" the trial court judgement dismissing his petition against Home Minister P Chidambaram in the 2G spectrum case and said he would soon prove it in the Supreme Court.

"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 and share dilution of companies," Swamy told a gathering here.

He was speaking on the topic '2G scam and its implications' at the second anniversary of Moneylife Foundation.

"Act of criminality will not come at trial stage. If (former Telecom Minister and key accused) A Raja is criminally liable, why Chidambaram's role cannot be probed? Conviction proceedings cannot be brought at trial stage. The judge acted on wrong basis. I will move the Supreme Court soon," Swamy said.

He said he would move the apex court soon against Chidambaram.

Swamy recalled that he started collecting evidence about the then Finance Minister's role in the scam after Prime Minister Manmohan Singh said on TV that Finance and Telecom Ministers had been authorised to decide on spectrum pricing as was the practice during the NDA regime.

"The government lost revenue because the prices were fixed at low level. In 2001, there were four million mobile sets while in 2008, the number was 700 million. The market had become huge," he said.

Speaking about anti-corruption movement in the country, Swamy said there was a need for him to join Anna Hazare and Ramdev.

"I and Ramdev addressed a huge rally on Saturday. Team Anna should give up its aversion to politicians. In a democracy, you cannot do without politicians and political parties," he said.
