This paper investigates whether the withdrawal of the United Kingdom from the European Union changed EU law. Brexit necessarily animated the law related to and produced by Article 50 TEU. Did it also imprint on fundamental premises of EU law that will continue to shape relations between the Member States and the Union, and between the Union and the wider world? These questions are examined through the examples of the legal force of political decision-making and the legal nature of relationships with third States. At one level, it will be seen that Brexit restored the centrality of Union institutions and processes in the EU law-making that responds to exceptional situations. At the same time, however, it has distorted and/or displaced some of the vital checks and balances that would normally apply. A course correction exploiting a rounded understanding of the effectiveness of EU law and provoking coherent articulation of the legal coordinates of Union membership is urged in response.

英国脱欧是否改变了欧盟法律？

本文调查英国退出欧盟是否改变了欧盟法律。英国脱欧必然会推动与第 50 条 TEU 相关并由其产生的法律。它是否也影响了欧盟法律的基本前提，将继续塑造成员国与欧盟之间以及欧盟与更广阔世界之间的关系？这些问题通过政治决策的法律效力和与第三国关系的法律性质的例子进行审查。在一个层面上，可以看出英国退欧恢复了欧盟机构和流程在欧盟立法中的中心地位，以应对特殊情况。然而，与此同时，它扭曲和/或取代了一些通常适用的重要制衡。
