Lawyers for Egypt’s ousted President and his co-defendants walked out of court on Sunday to protest the soundproof glass cage in which defendants are held during proceedings, state TV reported.

It said judge Shaaban el-Shamy ordered a recess after the lawyers left the hearing, the first in a case in which Mohamed Morsy and 35 others are facing charges of conspiring with foreign groups and undermining national security.

Judge el-Shamy, who later ordered the trial adjourned until February 23, 2014 was quoted by the private CBC TV network as telling the lawyers that the trial would proceed without them. It also reported that Mr. Morsy shouted at the start of the trial that he could not hear the proceedings.

Judge el-Shamy sent technicians to inspect the cage to verify Mr. Morsy’s claim, CBC said. The judge then ordered the volume raised to allow Mr. Morsy to better hear. The defence lawyers remained unsatisfied and walked out.

The cage was introduced after Mr. Morsy and his co-defendants interrupted the proceedings of other court cases by talking over the judge and chanting slogans. The cage is fitted to give the judge sole control over whether the defendants can be heard or not when speaking.

Mr. Morsy was ousted by the military following millions-strong protests demanding his step down after just one year in power. He, together with leaders of his Muslim Brotherhood, now face a multitude of trials on a range of charges, some of which carry the death penalty.
