Nobel laureate Mohamed ElBaradei, who recently quit as Egypt's interim vice president and left the country in the face of deadly crackdown on the Muslim Brotherhood supporters by military-led government, will face charges for "breaching national trust".

The case against ElBaradei, filed by an Egyptian law professor will be taken up by the Nasr City misdemeanour court on Sept 19.

Judicial officials said on Tuesday, that ElBaradei, will be sued in court for a "betrayal of trust" over his decision to quit the army-backed government in protest at its bloody crackdown on the Muslim Brotherhood. The charge could carry a $1,430 fine if he is convicted.

Sayed Ateeq, head of the Criminal Law Department at Helwan University's Faculty of Law, had filed the charges against the 71-year old Nobel laureate.

In his charge, Ateeq alleges that ElBaradei's resigned instead of presenting to the government any other alternatives to dispersing the sit-ins by Muslim Brotherhood who were protesting the ouster of Islamist president Mohammed Morsi and in disregard to their "terrorist crimes."

Ateeq charged that ElBaradei's resignation, created an impression among the international community that the Egyptian government used excessive force in dispersing the sit-ins by Brotherhood supporters.

Khaled Dawoud, a former aide to ElBaradei who joined him in quitting the interim National Salvation Front government following the military crackdown, said any decision to try the Nobel laureate would be a political escalation against critics of the military crackdown.

"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 is reported to have told Reuters.

ElBaradei, a former chief of International Atomic Energy Agency, who is currently in Austria with his family after leaving Egypt last week following the military crackdown, was involved in the coup d'état that toppled president Mohamed Morsi amid mass protests.

He was one of the opposition figures who met with Defence Minister Abdul Fatah al-Sisi in the days before the coup, as the "designated negotiator" for the political opposition. ElBaradei gave support to the military's plan to oust Morsi and begin implementing a "political road map" for Egypt.

However, ElBaradei, resigned as the country's interim vice president on Aug 14, after the security forces violently broke up protest camps set up by supporters of the deposed president, Mohamed Morsi. He felt that the beneficiaries of the crackdown would be those who call for violence, terrorism and the most extreme groups.

The military's intervention against Morsi has polarized public opinion in Egypt and around 900 people have died in violence across the country over the past week.
