Egyptian President Mohammed Mursi’s order to reconvene parliament has been rejected by the highest court, which says its ruling that led to the assembly’s dissolution is binding.
The speaker of the dissolved house has already responded to Mursi’s decree, calling on MPs to meet on Tuesday.
Army units outside parliament have left and some MPs have gone in.
The decision by Mursi, whose Muslim Brotherhood has most seats, sets up a potential showdown with the military.
However the situation is unclear as Egyptians elected Mursi without a constitution and without his powers being defined.
Because parliament has been dissolved, he was sworn in before the constitutional court rather than before MPs. (BBC)
