Oberlandesgericht Celle

Parties to the main proceedings

Applicant: Rechtsanwalt Dr Dirk Rüffert, as the liquidator of the assets of Objekt und Bauregie GmbH & Co KG

Defendant: Land Niedersachsen

Question referred

Does it amount to an unjustified restriction on the freedom to provide services under the EC Treaty if a public contracting authority is required by statute to award contracts for building services only to undertakings which, when lodging a tender, undertake in writing to pay their employees, when performing those services, at least the remuneration prescribed by the collective agreement in force at the place where those services are performed?
