Is democracy here for sale?"Notably, the National Assembly on Thursday kicked off a debate on the proposed constitutional amendments on a motion moved by Pakistan People's Party (PPP) lawmaker Naveed Qamar.Naveed said, "It is better to open the floor for a debate so that proposals be made part of the consensus document."Notably, the constitutional changes aims to include the extension of judges' retirement age and formation of a constitutional court. The moves have been staunchly opposed by former Prime Minister Imran Khan and his party, as reported by Geo News.Earlier, Pakistan's Supreme Court dismissed a plea challenging the proposed 26th Constitutional Amendment after the petitioner's lawyer requested its withdrawal, Geo News reported.The petition was filed by former president of the Supreme Court Bar Association and current member of the Pakistan Bar Council, Abid S Zubairi against the proposed constitutional amendments.Headed by Chief Justice Qazi Faez Isa, the three-member bench also comprised of Justice Naeem Akhtar Afghan and Justice Shahid Bilal Hassan.The petition objecting over the proposed constitutional amendment was dismissed by the apex court bench after Advocate Hamid Khan requested for taking back the plea. During the hearing, lawyer Hamid Khan requested the bench to withdraw the petitions. At this, the CJP questioned whether the petitioners had only hired Hamid, a leader of the PTI, to withdraw their pleas, Geo News reported."Abid Zubairi could have withdrawn the petition himself [...] Six lawyers had filed the petition; they could have appeared before the court themselves to withdraw it," the CJP said.Zubairi had filed the petition in the Supreme Court on September 16.
