This book examines how the EU and international law frameworks impact the EUs ability to act normatively in its external action in the area of fisheries. The EU, a major fishing power, portrays itself as a normative actor and a champion of sustainable fishing. The volume reconceptualises the Normative Power Europe narrative by identifying three interrelated elements universality, use of instruments, and legitimacy as the key criteria against which to evaluate the normativity of the EUs conduct. The universality element examines the level of international acceptance of the stated aims of EU action; the use of instruments element examines the EUs participation limitations in relevant international institutions and the means (persuasion as opposed to coercion) through which it acts; and the legitimacy element examines the substance of the EUs action in terms of legality, protection of common or self-interests, and coherence and consistency. The book draws upon extensive research into both the international and EU legal frameworks relating to fisheries and the EUs practice in its external fisheries relations. It consecutively discusses four sets of challenges: (i) to the EUs normativity posed by lack of membership in global institutions; (ii) created notwithstanding membership in other global or regional bodies; (iii) connected to multileveled coercive action and (iv) to accessing foreign fishing resources. It claims that, while the EUs normativity depends greatly on its internal and external powers, it is the EUs inability to freely wield these powers that damages its normativity. To act normatively, the EU primarily needs the full Member States support, as its present constitution prevents it from acting completely independently from them. The volume is aimed at academics and practitioners alike working in the area of fisheries globally but also on the EUs external action more generally.
