CAIRO - Egypt's new president ordered the dissolved Islamist-led parliament on Sunday to reconvene until a new one was elected, challenging the authority of the military generals who had dismissed the assembly based on a court ruling.President Mohamed Mursi was handed power on June 30 by the generals who had been in charge since Hosni Mubarak was ousted last year. But, shortly before handing over, the army curbed some presidential powers and gave itself a legislative role.Mursi's decision removes those legislative powers from the army and returns them to a parliament dominated by the party of Mursi's Muslim Brotherhood and its allies, analysts said.The state news agency MENA said the military council had held an emergency session to discuss the decree. A member of the council, who declined to be identified, told Reuters the generals had not been given prior warning of Mursi's decision.Mursi also called for an early vote once a new constitution was drawn up. That suggested a possible compromise by indicating that the assembly, criticized by some for a poor initial performance, would not serve a full four-year term."President Mohamed Mursi ordered the reconvening of the elected parliament to hold sessions," according to a presidential statement read out by Mursi's aide Yasser Ali.An early parliamentary election will be held within 60 days of a new constitution being approved by the nation, Ali said.Meetings of a body to draw up a new constitution are still in their early stages, delayed by rows between liberals, Islamists and others over who should write the new document.The Supreme Constitutional Court ordered the lower house of parliament dissolved on June 14 after finding fault with the election process. The generals implemented the decision two days later and then issued a decree outlining presidential powers on June 17, even before presidential election votes were counted.The Brotherhood has filed a legal suit in another court challenging the ruling to dissolve parliament, arguing such a decision should only be taken with popular consent.
