Fighting for Authority: Strategic Actions of National High Courts in the European Union

Abstract

National high courts in the European Union (EU) are constantly challenged: the European Court of Justice (ECJ) claims the authority to declare national standing interpretations invalid should it find them incompatible with its views on EU law. This principle noticeably impairs the formerly undisputed sovereignty of national high courts. In addition, preliminary references empower lower courts to question interpretations established by their national ‘superiors’. Assuming that courts want to protect their own interests, the article presumes that national high courts develop strategies to elude the breach of their standing interpretations. Building on principal-agent theory, the article proposes that national high courts can use the level of (im-) precision in the wording of the ECJ’s judgements to continue applying their own interpretations. The article develops theoretical strategies for national high courts in their struggle for authority.
