Addressing a "sanctity of vote" seminar in Islamabad, the thrice prime minister said that only the people had right to entrust a person with the leadership of the country, adding that the history of Pakistan wasn't very pleasing.
Sharif called for an end to muzzling media and individuals.
"PEMRA has also been directed by the LHC to strictly monitor TV channels with regard to airing any anti-judiciary speeches/remarks and submit a report after 15 days", a court official told PTI.
Counsel for one of the petitioners, Azhar Siddiqui informed the court that Pemra did not take any action over petitions filed with it regarding alleged anti-judiciary speeches by PML-N leaders.
Representing the regulator, Advocate Salman Akram Raja argued that the petitioners were raising unnecessary objections against the regulatory body's authority, which was taking steps to decide all the complaints on the matter. It made sense for a lawyer or an expert in legal matters to comment on judicial verdicts, the judge added.
Multiple petitions have been filed in different courts against them over alleged contempt of court.
The ousted premier said Pakistan belonged to everyone equally and every citizen had the same rights.
The chief justice observed that the high court passed such orders in compliance with Article 19 (Freedom of speech) and 68 (Restriction on discussion) of the Constitution.
The larger bench, headed by Justice Mazahir Ali Akbar Naqvi, gave this verdict on petitions seeking initiation of contempt cases against former premier Nawaz Sharif, Maryam Nawaz and other PML-N leaders for criticizing the judiciary.
