Egypt's highest court has overruled President Mohamed Morsi's decision to recall the Islamist-led parliament that was dissolved by the nation's military leaders last month.

A judicial source said the ruling came hours after Egypt's Islamist-led lower house of parliament reconvened briefly Tuesday in defiance of orders by the country's military and Supreme Court.

President Morsi Sunday issued a decree that reinstated the body until a new legislature is elected.

Egypt's supreme military council dissolved the parliament last month after the Supreme Constitutional Court found fault with the process by which lawmakers were elected. The court said Monday its decision was final and binding.

The speaker of the lower house said lawmakers were meeting to find a way to implement the court ruling.

U.S. Secretary of State Hillary Clinton has urged Egyptian officials to work together to avoid derailing the country's transition.

Meanwhile, German Foreign Minister Guido Westerwelle held talks with Mr. Morsi in Cairo. Afterward, Westerwelle said he feels confident the country can resolve its political struggle.
