Asif Saeed Khosa, previously a judge on the high court, began his new duties Friday. He replaces Mian Saqib Nisar, who during his term as the chief justice disqualified ex-premier Nawaz Sharif from holding office as part of a corruption case. In case, Nisar last year acquitted a Christian woman, Aasia Bibi, who was on death row for eight years, in a blasphemy case. However, Nisar became controversial because of his intervention in government affairs. Khosa says he will work to reform the country’s judicial system to ensure speedy justice to all.
