Former minister Aitzaz Ahsan, who will appear as the Prime Minister's lawyer when Yousuf Raza Gilani faces an apex court bench tomorrow over a contempt notice, also said that the premier is not guilty of contempt of court but should bow to pressure and ask Switzerland to reopen graft cases.
Ahsan said the President's immunity had been notified and was guaranteed under the Constitution.
He further said that since the President enjoys constitutional immunity? therefore? the contempt notice against the Prime Minister is not valid.
The President's immunity in criminal cases had been endorsed by accountability or anti-corruption courts, Ahsan said while interacting with reporters in Islamabad.
Similarly? cases cannot be initiated against the President in Switzerland as he enjoys immunity in that country under the Vienna Conventions, he said.
Under the Vienna Conventions, Zardari enjoys immunity as long as he holds the office of President, he said.
Since 2009, the Supreme Court has been pressuring the government to reopen cases of alleged money laundering in Switzerland against Zardari after striking down the National Reconciliation Ordinance, a graft amnesty that was issued by former military ruler Pervez Musharraf.
The government has refused to act on the court's orders, saying the President enjoys immunity under the Constitution.
On Monday, the Supreme Court issued a notice for contempt of court to Gilani for failing to revive the corruption cases and summoned him to appear in person tomorrow.
