Judgment_paragraph 45 · Abdelkader Dellas and Others v Premier ministre and Ministre des Affaires sociales, du Travail et de la Solidarité (C-14/04)

45The Court concluded that the Member States cannot unilaterally determine the scope of those concepts and of the other provisions of Directive 93/104 by imposing any condition or restriction on the right granted to workers by that directive to have working periods and corresponding rest periods duly taken into account. Any other interpretation would frustrate the effectiveness of the directive and disregard its objective of guaranteeing effective protection of the safety and health of workers by means of minimum requirements (see Jaeger, paragraphs 59, 70 and 82, and Pfeiffer and Others, paragraph 99).
