Judgment_paragraph 54 · Cristiano Marrosu and Gianluca Sardino v Azienda Ospedaliera Ospedale San Martino di Genova e Cliniche Universitarie Convenzionate (C-53/04)

54It is not for the Court to rule on the interpretation of national law, that being exclusively for the national court which must, in the present case, determine whether the requirements set out in the preceding three paragraphs are met by the provisions of the relevant national legislation. However, the Court, when giving a preliminary ruling, may, where appropriate, provide clarification designed to give the national court guidance in its interpretation (see Case C-255/02 Halifax and Others [2006] ECR I-1609, paragraphs 76 and 77).
