President Asif Ali Zardari signed the amended Contempt of Court Bill 2012 into law on Thursday.
After go-ahead by the president, the bill became part of the constitution in an apparent move vis-à-vis Supreme Court (SC) to save disqualification of Prime Minister Raja Pervez Ashraf in the footsteps of former prime minister Yousaf Raza Gilani, who was sent home over contempt charge.
Earlier on Wednesday, the Upper House of the Parliament adopted the bill amid a strong protest by Pakistan Muslim League-Nawaz (PML-N).
The bill, which exempts prime minister, governors, chief ministers, federal ministers and state ministers from contempt proceedings over right criticism, had already been passed by the National Assembly on Monday.
