ISLAMABAD: A larger bench of the Supreme Court began hearing of contempt of court case against Prime Minister Syed Yousuf Raza Gilani Wednesday, Geo News reported.

The seven-member larger bench is headed by Justice Nasir ul Mulk.

During proceedings, Justice Nasir remarked that there is no need for contempt proceedings if the immunity is proved, adding that the PM said the decision not to write the letter to Swiss authorities was his own.

PM Gilani's counsel barrister Aitzaz Ahsan argued that the premier could not read detailed verdict of the court he has to act on advice of aides. 'Law Minister and Secretary advised the prime minister.'

He said President of Pakistan has immunity both in and outside the country. ‘My opinion was there is no issue in writing letter,’ Aitzaz said.

Didn't PM violate orders by refusing to write letter, Justice Khosa asked. 'He acts on advice of aides, not on orders of court.' Is this the sincerity that your client doesn't write letter, he observed.

Aitzaz argued that for implementation, the case should have gone to the High Court.

On January 19, giving his point of view before the seven-member bench, Prime Minister Gilani said the president enjoys complete immunity, not only in Pakistan but also in the world as enunciated by the Constitution.
