Egypt's top court has ruled its decision to dissolve the new parliament is “final” and binding, setting the stage for a showdown with President Mohamed Morsi.

The ruling comes the day after Mr. Morsi ordered the lawmakers to start meeting again and hours after speaker Saad el-Katatni called for parliament to meet Tuesday.

The Supreme Constitutional Court ordered the parliament dissolved last month after finding fault with the election process. The then-ruling military generals implemented the decision and gave themselves legislative powers.

The new president has also issued an order for parliamentary elections to be held within 60 days of the adoption of Egypt's new constitution, which is expected later this year.
