CAIRO (AP) — A Cairo court has postponed to July 30 a key ruling that will determine the legality of an Islamist-dominated panel tasked to write Egypt’s new constitution.

Thursday’s postponement came after lawyers of the country’s most influential Islamic political group, the Muslim Brotherhood, challenged judges of the High Administrative court hearing the case and demanded they be replaced.

The 100-member constitutional panel formed in June by Egypt’s now-dissolved parliament had an Islamist majority, and its voting rules allow that majority to override objections by liberals, secularists, and others.

The panel was dissolved in April after liberals filed appeals in front of the same court.
