The case, Reuters reported , is to take place on September 19, and was filed by a university law professor, Sayyed Ateeq."I raised a case against Dr. ElBaradei. He was appointed in his capacity as a representative of the NSF and the majority of the people who signed the Tamarod declaration," Mr Ateeq told Reuters, in a reference to the coalition that led the anti-Mursi protests."Dr. ElBaradei was entrusted with this position and he had a duty to go back to those who entrusted him and ask to resign."ElBaradei, who left Egypt earlier this week for Europe, could face a three year jail sentence, Mr Ateeq told Reuters, although a judicial source said that if found guilty, a fine would be imposed over a jail sentence.The former head of the U.N. nuclear agency quit his post as Egypt's Vice-President in protest at the violent crackdown against the Muslim Brotherhood.News of his trial comes in the wake of a wave of arrests of Muslim Brotherhood leaders. Khaled Dawoud, a former aide to ElBaradei, told Reuters that any decision to try the Nobel peace prize winner would mark a significant political step. "If this case against ElBaradei is true then it is a major escalation showing that things are getting very polarized. You're either on this side or on that side," he said.
