Mohamed ElBaradei criticized on Sunday president Mohamed Mursi's decision to reinstate the parliament and allow it to reconvene and continue its tasks.
In a tweet in English, ElBaradei wrote, "The executive decision to overrule the Constitutional Court is turning Egypt from a government of law into a government of men."
"The executive decision of reinstating the parliament is a waste of judicial authority, takes Egypt into a coma and means a struggle amongst authorities. May God help you, Egypt," ElBaradei, former director of the International Atomic Energy Agency and founder of the Constitution Party, wrote in a tweet in Arabic.
The Supreme Constitutional Court, the highest judicial authority in Egypt, ruled on June 14 that the parliamentary elections law is unconstitutional because it does not give equal chances to individual and partisan candidates to compete for individual seats which led to the parliament's dissolution.
