ISLAMABAD: The 26th Amendment has been challenged by former parliamentarians and an ex-president of the Sindh High Court Bar Association (SHCBA) in two separate petitions, seeking nullification of the judiciary-centric constitutional tweaks.The coalition government had passed the contentious constitutional package in both houses of parliament on night between October 20-21 after month-long political deliberations between treasury and opposition lawmakers. The latest petitions raised the total number of challenges to eight against the 26th Amendment containing a set of laws related to the country’s judiciary, including fixing three-year term of the Chief Justice of Pakistan (CJP) as well as the formation of constitutional benches. In one of the petitions filed in the apex court on Friday, the petitioners include Balochistan National Party—Mengal (BNP-M) President Akhtar Mengal, former National Assembly speaker Fahmida Mirza, National Democratic Movement (NDM) Chairman and ex-lawmaker Mohsin Dawar, and former (PPP) senator Mustafa Nawaz Khokhar.
