This article discusses the judgments handed down by the Court of Justice in reply to Hungary and Poland's request to annul Directive 2018/957 which had introduced a number of amendments to the Posting of Workers Directive 96/71. Through these amendments, the European legislator had extended the scope of the employment protection of posted workers and these two Member States were of the opinion that this measure was in conflict with the Treaty provisions on the free movement of services. First, this article will briefly examine the amendments to the Posting of Workers Directive. Then, it will analyse the Court's responses to Hungary and Poland's arguments. At the end, a brief evaluation follows.
