European Union – Rules on competition. The Court of Justice of the European Union ruled that art 101 of the Treaty on the Functioning of the European Union, read in conjunction with art 4(3) of the Treaty on the European Union, had to be interpreted as precluding national legislation, pursuant to which the price of haulage services for hire and reward might not be lower than minimum operating costs, which were fixed by a body composed mainly of representatives of the economic operators concerned.
