Since these proceedings are, for the parties to the main proceedings, a step in the action pending before the national court, the decision on costs is a matter for that court. Costs incurred in submitting observations to the Court, other than the costs of those parties, are not recoverable.
On those grounds, the Court (Grand Chamber) hereby rules:
Articles 3, 5 and 6 of Directive 2003/88/EC of the European Parliament and of the Council of 4 November 2003 concerning certain aspects of the organisation of working time, read in the light of Article 31(2) of the Charter of Fundamental Rights of the European Union, and Article 4(1), Article 11(3) and Article 16(3) of Council Directive 89/391/EEC of 12 June 1989 on the introduction of measures to encourage improvements in the safety and health of workers at work, must be interpreted as precluding a law of a Member State that, according to the interpretation given to it in national case-law, does not require employers to set up a system enabling the duration of time worked each day by each worker to be measured.
