Another voice in the increasingly chaotic debate over Egypt's transition: Saad al-Katatni, the parliament speaker, held a press conference earlier today in Cairo, and said the current constitutional declaration - issued last year by the ruling Supreme Council of the Armed Forces - does not give anyone the authority to dissolve parliament.

His comments came days before the supreme court is due to rule on whether parliament is constitutional or not. A lower court found that some aspects of the electoral process - allowing political parties to compete against individual candidates for certain seats - were unconstitutional.

If the supreme court agrees, conventional wisdom is that parliament would be dissolved. But Katatni, a member of the Muslim Brotherhood's Freedom and Justice Party, disagrees. "The constitutional court has the full right to make its decision, but it does not have the right to implement it," he said.
