Chief Justice Saqib Nisar on Friday took a suo motu notice of "anti-judiciary" speeches made by PML-N leader Daniyal Aziz.
Aziz has been asked to appear before the court on February 7 when the contempt of court proceedings against the PML-N leader will be taken up.
A day earlier, the SC had found Senator Nehal Hashmi guilty of committing contempt of court. The court sentenced him to one-month imprisonment, barred him from holding public office for the next five years, and imposed a fine of Rs50,000.
In May 2017, as a Supreme Court-mandated joint investigation team was probing the Sharif family's business dealings in the Panama Papers case, Hashmi had warned that those conducting the investigation would be "taken to task" for grilling the premier's family. The video of Hashmi's remarks had gone viral on social media and was also aired on news channels.Also on Thursday, the chief justice had taken suo motu notice of "contemptuous speeches" made by PML-N leader and state minister Talal Chaudhry.
During his speech at PML-N's rally in Jarranwala last week, Chaudhry had said: "There was an era when the Kaabah was full of idols. Today, the judiciary, which is the country's highest institution, is also full of PCO [Provisional Constitution Order] idols."
"Mian Nawaz Sharif, throw them out, throw him out of the court. They will not give justice but will continue their injustices."
The Lahore High Court (LHC) has already served notices to Nawaz Sharif, Maryam Nawaz and Rana Sanaullah in a contempt of court petition regarding the same gathering.
