Judgment_paragraph 81 · Vereniging voor Energie, Milieu en Water and Others v Directeur van de Dienst uitvoering en toezicht energie (C-17/03)

81As the Court has already ruled, an individual cannot place reliance on there being no legislative amendment whatever, but can only call into question the arrangements for the implementation of such an amendment (see, with regard to a legislative amendment removing the right to deduct value added tax in respect of certain costs connected with lettings of immovable property, Joined Cases C-487/01 and C-7/02 Gemeente Leusden and Holin Groep [2004] ECR I-5368, paragraph 81). In like manner, the principle of legal certainty does not require that there be no legislative amendment, requiring as it does, rather, that the legislature take account of the particular situations of traders and provide, where appropriate, adaptations to the application of the new legal rules.
