Counterterrorist sanctions against individuals are a prime example of pluralism. Multiple claims of constitutional authority (in resolutions of the UN Security Council, under European Union law, and national law) assume to govern the same legal situation. Choosing between these different authorities has great implications for the legal situation of individuals. This paper analyses the legal position of individuals facing this plurality of claims of constitutional authority and how their rights are largely dependent on the choices of domestic courts. Attention will be given not only to procedural and judicial rights but also to the broader implications of individual sanctions as an example of pluralism. What does it mean for popular sovereignty? Do patterns or guidelines emerge of how courts should address multiple claims of authority? The paper takes into account the latest amendments of the UN sanctioning procedure (Resolutions 1988 and 1989 (2011)).
