A Cairo court has postponed a key decision on overturning the ruling military council's order to disband the Islamist-dominated parliament.

Cairo's Administrative Court on Tuesday set July 7 as the date for ruling on the legality of dissolving the 498-member parliament, a case brought by a number of lawmakers.

The same court postponed to Sept. 1 an appeal that sought to disband a 100-member panel appointed by parliament to draft a new constitution.

The ruling military council has used court decrees and constitutional declarations to stop Islamists from controlling all the executive and legislative branches after last year's uprising that ousted Hosni Mubarak's authoritarian regime.

On Sunday, Islamist Mohammed Morsi of the fundamentalist Muslim Brotherhood was declared Egypt's first freely elected president in modern history.
