Multiple assassination attempts have failed to remove President Pervez Musharraf from power, yet unrest caused by his suspension of the Supreme Court’s chief justice threatens his authority. Protesters say that Iftikhar Chaudhry, handpicked by Musharraf, was removed over concern he would question the president’s hold on the army chief post in fall 2007 presidential elections. The chief justice has refused to go quietly. Highlighting tensions, a court official was murdered in his home (Australian) hours before a pivotal Supreme Court hearing on the matter. A BBC backgrounder examines the judicial crisis.
