Egypt's Supreme Constitutional Court adjourned on Sunday its session to consider legal challenges to two Islamist-led bodies due to a protest demanding its dissolution.
A few thousand protesters gathered by the supreme court in Maadi on Sunday, chanting against it and demanding its dissolution.
The court did not say when its next session on the legality of the constitution-writing body and the Shura Council (parliamentary upper house) will take place.
Egypt's highest court is expected to issue a statement of its stance on the unfolding events shortly, reported the state's news agency.
Judges sitting on the case were unable to enter the court due to the protest even though the Interior Ministry said on Sunday morning that measures to secure the court were underway.
Head of the Muslim Brotherhood's Freedom and Justice Party Mohamed al-Katatni asked the protesters to refrain from disturbing the court's operations, insisting on the party's rejection of violence.
Meanwhile, opposition leader Mohamed ElBaradei remarked on Twitter, "Constitutional court intimidated and under siege by pro Mursi protesters. Judiciary almost entirely crippled. Where are we heading?"
