An appeal to cancel a law, decree or ordinance may be submitted to the Court by the Council of Ministers, by the Government of a Community or Region of Belgium, by the Presidents of the Chamber of Representatives, Senate and the Community and Regional Parliaments, at the request of two-thirds of its members, and by any person who can demonstrate an interest in the cancellation. In other words, the law, decree or ordinance must be harmful to the party submitting the appeal.
