Following a reference from a German court, the European Court of Justice (ECJ) gave a ruling in late 2007 (in C-337/06), that a public broadcasting body could be regarded as being "financed by the state" and therefore under the scope of the public procurement rules, if it receives more than 50 per cent of its revenue from fees levied on citizens pursuant to state measures. The issue arose following a challenge before the national courts concerning a tender procedure for a contract for cleaning services for a broadcasting company that had not been formally advertised and allegedly did not comply with the procurement rules. One of the issues raised before the national court in determining whether broadcasting companies fall within the definition of "a body governed by public law", was whether financing through broadcasting fees amounted to financing through state resources. The ECJ held that it did, since fees are imposed through law upon owners of a broadcasting receiver and not as a result of a contractual arrangement between customers and the broadcaster for services.
