CAIRO (AFP) - The trial of ousted Egyptian president Hosni Mubarak which was due to resume on Sunday has been postponed following demands for the appointment of a new judge, state-run news agency MENA reported. A new hearing has been set for December 28, MENA said. "The Cairo criminal court, chaired by Judge Ahmed Refaat, decided to adjourn the trial of former president Hosni Mubarak, his sons Alaa and Gamal, businessman Hussain Salem, former interior minister Habib al-Adly and six of his assistants to December 28," MENA said. Lawyers for alleged victims of Mubarak in his murder trial have petitioned the court demanding that judge Refaat be replaced. "The court has lost its jurisdiction by not administering the sessions in a manner conforming with the course of justice," one of the victims' lawyers, Abdel Moneim Abdel Maqsud, said on September 24. MENA said the trial will resume once a decision has been taken on call to replace Refaat, who has defended the court's integrity in previous sessions while lashing out at critics. An appeals court is due to give a verdict on December 26.
