Egypt's highest court on Sunday invalidated the country's Islamist-dominated Senate and a panel that drafted the country's constitution, state media reported.
The Supreme Constitutional Court (SCC) said the law governing the elections of the Shura Council was unconstitutional, as were the rules for the selection of the members of a committee that drafted the constitution.
Presiding Judge Maher al-Beheiry said that the Shura Council should remain in place until the election of a new parliament, but it had no authority to legislate, judicial sources said.
The case against the Shura Council is based on several challenges by lawyers of the law that governed the election of its members.
Both the upper and lower houses were elected under the same electoral law, which the SCC last year deemed invalid, prompting the dissolution of parliament.
