This article explores how the concept of jus cogens is understood and practiced in the field of international law. While the concept has gained mass acceptance and recognition, the actual legal significance and application is still very much unclear. In Article 53 of the Vienna Convention on the Law of Treaties, peremptory norms are defined as those which are ‘non-derogable’ but nevertheless require the ‘acceptance and recognition’ from the international community as a whole. This process of acceptance and recognition had to be developed through state practice and judgments from international courts and tribunals. Accordingly, this article examines how jus cogens has been interpreted by those actors, without ignoring the contributions from academic scholarship and reports of the International Law Commission. Through analysing these sources, it becomes clear that the task of clarifying the content and legal meaning of the concept is continuously being deferred amongst the relevant actors. After demonstrating this tendency, the remaining sections of the article discuss why this is happening, whether it is forth fixing and if so how that change could come about.

打破延缓辩护的周期：国际法实践中的强制法

本文探讨如何在国际法领域中理解和实践强制法的概念。尽管该概念已经得到了大众的认可和认可，但实际的法律意义和应用仍然非常不清楚。《维也纳条约法公约》第53条将强制性规范定义为“不可克减”但仍然需要整个国际社会“接受和承认”的规范。这种接受和承认的过程必须通过国家实践和国际法院和法庭的判决来发展。因此，本文探讨了这些行为者如何解释强制法，而没有忽略学术奖学金和国际法委员会报告的贡献。通过分析这些来源，显然，在相关行为体中，不断澄清概念的内容和法律含义的任务。在展示了这种趋势之后，本文的其余部分讨论了这种情况的发生原因，是否正在解决以及如果发生这种变化如何发生。
