Thousands of Egyptians have gathered in Cairo's Tahrir Square to protest attempts by the Constitutional Court to revoke a decree by freshly inaugurated President Muhammad Morsi.
The decree orders lawmakers to reconvene the Islamist-dominated parliament, which had been dissolved by military leaders in the powerful Supreme Council of the Armed Forces.
On July 10, lawmakers briefly reconvened in Cairo and voted to seek judicial advice on a Constitutional Court ruling that invalidated the election of one-third of the deputies.
The Constitutional Court has rejected Morsi's decree, saying its rulings are not subject to appeal.
Morsi, the Constitutional Court, and the military's Supreme Council remain deadlocked over the issue.
After the parliament was ordered to disband, the Supreme Council issued a decree assigning all legislative authority to itself.
But Morsi says the parliament must reconvene until new elections are held.
