Member of Parliament Bassel Adel, from Al-Masryeen Al-Ahrrar, asked for the runoff round of the presidential election to be halted until a decision is reached on the constitutionality of the political exclusion law.
Egypt's elected-parliament had proposed the law to disqualify Shafiq and former Mubarak ex-spy chief Omar Suleiman from the race.
While Suleiman was disqualified for failing to meet the requirements, Shafiq appealed the law which was then referred to the Constitutional Court to approve its validity. The fate of the law remains unknown and Shafiq remains in the race.
Shafiq, who served as Mubarak's last premier, is competing in the second round of the election, scheduled for June 16 - 17, against the Muslim Brotherhood's Mohamed Mursi.
Adel explained that the presidential election will be stripped of its legitimacy if the court was to declare the law constitutional. He criticized the Presidential Elections Committee's failure to apply justice.
He added that the parliament's proposal of the law is in agreement with their legitimate duties stated in the Constitutional Declaration - and was agreed upon by the executive authority, represented in the ruling military council.
Adel urged the parliament to issue a law that prevents the second round from proceeding before the court declares its stance on the law.
