CAIRO – Egypt's Supreme Judicial Council has agreed to supervise a referendum on a draft constitution, a legal adviser to President Mohamed Morsi said Monday, although some judges have called for a boycott. Judicial dissent has complicated the Islamist leader's plan to end a crisis over Egypt's troubled political transition by driving through a new constitution in a snap vote on Dec. 15. The judiciary oversees voting in Egypt by law. The influential but unofficial Judges Club urged colleagues Sunday to shun the referendum which Morsi hopes will douse anger over a decree he issued on Nov. 22, greatly expanding his powers and temporarily putting himself above the law. Such a boycott, even if not all judges joined it, could undermine the credibility of the plebiscite and worsen disputes that have plagued Egypt's path to political change since a popular revolt overthrew Hosni Mubarak nearly 22 months ago. The judiciary, like Egyptian society at large, is split over the vote on the constitution, the way in which it was drafted and Morsi's decree, seen by his opponents as a power grab and by his supporters as necessary to keep the transition on track. “The Supreme Judicial Council has met and agreed to delegate judges to oversee the constitutional referendum," Mohamed Gadallah, the legal adviser to Morsi, said. He said about 10,000 members of the judiciary are needed to monitor the vote. These do not all have to be judges and could include officials in prosecutors' offices for example. There was no immediate comment from the judicial council, the body which formally oversees judicial affairs. “It is still unclear how many judges will be boycotting," said Elijah Zarwan, a fellow with The European Council on Foreign Relations, adding that even a partial boycott could hurt the credibility of the referendum. Many judges voiced outrage at Morsi's Nov. 22 decree, which caused unrest in which three people were killed and hundreds wounded. Even his justice minister and vice president – brothers who were formerly respected judges who advocated judicial independence in Mubarak's time – have expressed misgivings. The constitution, which if approved would override the decree, is itself contested by opposition groups who say the Muslim Brotherhood hijacked the drafting of a document they say has no legitimacy in a deeply polarized society. “Settling this matter using the ballot box is an illegitimate trick representing false democracy," liberal opposition leader Mohamed ElBaradei said on his Twitter feed. The opposition has called for another mass protest Tuesday in Cairo's Tahrir Square, the cradle of the anti-Mubarak revolt. Morsi's opponents have camped out there since Nov. 23. The Judges' Club boycott call carries echoes of Mubarak's days, when independent-minded sections of the judiciary refused to oversee elections unless he enacted judicial reform. One leading figure in that campaign for judicial independence, former Judges' Club head Zakaria Abdel Aziz, said the judges had a “national duty" to oversee this referendum. “A lot of judges called me and they are heading in the direction of supervising the referendum," he said. – Reuters
