CAIRO (AP) — Egypt’s highest court has ordered the country’s Islamist-dominated parliament dissolved, saying its election about six months ago was unconstitutional.

The Supreme Constitutional Court ruled Thursday that a third of the legislature was elected illegally. As a result, it says in its explanation of the ruling, “the makeup of the entire chamber is illegal and, consequently, it does not legally stand.”

The explanation was carried by Egypt’s official news agency and confirmed to The Associated Press by one of the court’s judges, Maher Sami Youssef. The ruling means that new elections for the entire parliament will have to be held.
