The cases deal with the imposition of sanctions on individuals and groups associated with Al-Quaeda, Usama bin Laden and the Taliban by the Community as a consequence of United Nations Security Council resolutions calling for the freezing of funds controlled by those individuals or groups. In particular, the Council adopted Regulation 881/2002 to give effect to those resolutions. The Commission updated it regularly by reviewing the list of persons to which it applied on the basis of updating by the UN Sanctions Committee.
A number of individuals concerned by the measures brought an action to annul the Council and Commission implementation of the Security Council resolutions on the grounds that their human rights had been infringed in various ways, most notably because they had no right to be heard before the measures were taken.
The judgments of the Court are long but richly reasoned. They deal neatly with the relationship between EC law and the international obligations of the member States. The Court finds that it has no jurisdiction to review the legality of the Security Council resolutions in principle but that it does have the power to scrutinize the lawfulness of the EC regulation challenged and indirectly the Security Council resolutions implemented by that regulation in the light of the higher rules of international law falling in the scope of jus cogens understood as peremptory norm of public international law from which neither the member States of the EC nor the different bodies of the UN can derogate. Jus cogens includes the mandatory provisions intended to secure universal protection of fundamental human rights.
The Court also finds that the fundamental rights of the plaintiffs protected by jus cogens were not in fact breached : Neither their right to property, nor their rights of defense (right to be heard) nor their right to effective judicial review.
The judgments are worth reading in their entirety. That will keep you out of mischief for a while.
