Premier Yousaf Raza Gilani's legal team is finalising an appeal to be filed in Pakistan's Supreme Court seeking suspension of its order summoning him on February 13 for framing of contempt charges over his failure to reopen graft cases against the president.
The intra-court appeal is expected to be filed after a few days, media reports said.
The premier has already announced that he will appear in the apex court and respect any orders passed by it.
"We are in the process of preparing the appeal which may take a couple of days more and (it) will be filed instantly afterwards," an unnamed associate of Aitzaz Ahsan, Gilani's lawyer, told the Dawn newspaper.
Another member of Ahsan's team told The News daily that the appeal could be filed by Wednesday or Thursday.
A seven-judge apex court bench last week summoned Gilani to appear before it on February 13 for framing of contempt charges for failing to act on its order to reopen graft cases against President Asif Ali Zardari.
Gilani had personally appeared before the bench headed by Justice Nasir-ul-Mulk when it first took up the contempt case on January 19.
Since December 2009, the Supreme Court has been pressuring Gilani's government to reopen cases of alleged money laundering against Zardari in Switzerland after striking down the National Reconciliation Ordinance, a graft amnesty passed by former President Pervez Musharraf.
Zardari and his late wife, former Prime Minister Benazir Bhutto, have been accused of laundering about USD 12 million in Swiss banks after they allegedly accepted bribes from firms seeking customs inspection contracts in Pakistan in 1990s.
