European Union – Air Transport. The Court of Justice of the European Union made a preliminary ruling, deciding that the Convention for the Unification of Certain Rules for International Carriage by Air, in particular arts 19, 22 and 29 thereof, should be interpreted as meaning that an air carrier which had concluded a contract of international carriage with an employer of persons carried as passengers, such as the employer at issue in the main proceedings, was liable to that employer for damage occasioned by a delay in flights on which its employees had been passengers pursuant to that contract, on account of which the employer had incurred additional expenditure.
