Hundreds of Muslim Brotherhood supporters gathered outside of the High Court in Cairo on Friday to protest against the judiciary. They chanted, “the people want the purging of the judiciary,” and held signs asking for the “retribution of the martyrs.”

On a wall outside the High Court hung a banner outlining protesters’ demands: immediate change of the current judicial law, removal of the justice minister, prosecution of both the head of the Judge’s Club and the former chief prosecutor, and the holding of revolutionary tribunals.

The protest comes in light of South Cairo Criminal Court’s ruling earlier in the week acquitting deposed president Hosni Mubarak of charges of killing protesters during the revolution, although a retrial is scheduled for May 11. He remains in jail on corruption charges. The decision, as well as Mubarak’s visibly improved health and cheerful spirits on Monday, frustrated many Egyptians with the continued delay of justice against the previous regime.

In a jibe at the legal system, one protester Friday held a sign portraying a man symbolizing the judiciary holding a gun to the back of an angel-winged martyr that sarcastically read: “Urgent: martyrs now being arrested on false proclamations and without reason.”
