Afghanistan's president swore in the chief justice and five other judges of the country's new Supreme Court during a ceremony at the presidential palace, a statement said on Sunday. President Hamid Karzai presided over the ceremony, days after the country's fledgling parliament approved his nominees amid calls for wide-ranging reforms to stamp out corruption and political interference in the judiciary. The parliamentary approval came as a relief for US-backed Karzai, who has already had one nominee for the Supreme Court's top job rejected. US-educated Abdul Salam Hazami, once deputy head of the commission that drew up Afghanistan's new constitution, became chief justice.
