Gilani's lawyer Aitzaz Ahsan is likely to file an appeal in a few days against the apex court's order summoning the premier on February 13 for the framing of contempt of court charges for failing to act on orders to reopen graft cases against President Asif Ali Zardari.
The government's stand in the matter has been influenced by its desire to ensure that nothing affects the holding of polls to the Senate or upper house of parliament scheduled for next month, The Express Tribune quoted its sources as saying.
The PPP's top leaders have advised cadres "not to resort to public rhetorical attacks against the assertive judiciary", the report said.
The PPP will fight its case in court "with all its might", arguing that Zardari enjoys immunity under the Constitution from prosecution in all criminal proceedings inside and outside the country.
Most PPP leaders were tight-lipped when asked to comment on yesterday's proceedings in the apex court.
However, a majority of them said during informal interactions that the government was being "squeezed" by the judiciary.
"We have a right to go for a review, as has been mentioned by the counsel of the PM," an unnamed PPP leader said.
"One should not forget that after the 18th Amendment that right of a fair trial has been recognised as a basic right of every citizen under clause 10A of the Constitution."
