Egypt’s Supreme Constitutional Court has rejected a draft election law, a move that could delay parliamentary polls.

Elections were planned to be announced in February and held in April.

The draft law has been sent back to the parliament’s upper house for amendments, with the Supreme Court rejecting a number of articles, including plans on how electoral districts would be designated.

The constitutional court has been at loggerheads with President Mohamed Mursi since he took power last June. The rift eventually resulted in Mursi issuing a decree that gave him powers not subject to a judicial review.

Mursi continues to face protests against his rule, with demonstrators angered by the new president’s autocratic rule and failed attempts to revive Egypt’s economy. Demonstrations are still continuing at Port Said near the Suez Canal forcing businesses to temporarily close down.
