SYDNEY (AFP) - Papua New Guinea's Supreme Court on Friday ordered the arrest of the deputy prime minister and attorney general on contempt charges after they suspended the chief justice. Deputy Prime Minister Belden Namah and Attorney General Allan Marat were ordered to be brought before the court after they suspended Sir Salamo Injia on Thursday, the Australian Broadcasting Corporation reported from Port Moresby. The move came less than a month before Injia was to deliver a verdict on the constitutional legitimacy of Prime Minister Peter O'Neill's election in August to lead the poverty-stricken but resource-rich Pacific country. O'Neill took power from ailing long-time leader Sir Michael Somare when he was elevated to the top job by a majority vote of lawmakers after they ruled the prime ministership vacant due to Somare's absence because of illness. Namah and Marat said Injia was suspended pending an investigation into multiple charges, including mismanagement of court funds. "The Registrar of the Supreme Court shall file and serve charges on two alleged contemnors the Hon Belden Namah and the Hon Dr Allan Marat within seven days," the court order said Friday. The order also prevents the government from going through with Injia's suspension. O'Neill was out of the country at the APEC summit in Hawaii.
