Egypt's constitutional court rejected five articles of a draft election law on Monday and sent the text back to the country's temporary legislature for redrafting in a ruling that may delay a parliamentary poll due in April.
"The court has returned the draft parliamentary electoral law to the Shura Council after making five observations on five articles which it found unconstitutional," a court statement said.
It did not immediately disclose which parts of the law had been censured, but the court said it would issue a fuller statement later in the day.
A source in President Mohamed Mursi's office said before the decision that if the court found fault with the law, it could delay passage of the law, and hence the election, by a couple of weeks, but probably not months.
Mursi had been expected to promulgate the electoral law by February 25 and set a date two months later for voting, probably in more than one stage for different regions because of a shortage of judicial poll supervisors.
