EuGH: Obligation to comply with the collective agreement inadmissible!
With its decision of 3 April 2008 (Case C-346/06) the ECJ rejects the regulation on compliance with collective agreements of the Federal States which pledges companies in writing to pay their employees at least the pay rate agreed upon at the place of performance when awarding the contract. Contrary to the judgement of the Constitutional Court of 11 July 2006, the ECJ considers the requirement of such a local obligation to comply with collective agreements a restriction of a free exchange of services which aggravetes the provision of services in another Member State because of the additional economic burden. It is also inadmissible to impose working conditions on companies domiciled in other Member States in the transnational provision of services, working conditions that exceed the mandatory regulations of a minimum level of protection (minimum wage). Therefore, the Bavarian Works Contracts Procurement Act (BayBauVG)that currently can not refer to a generally applicable collective agreement will presumably be overruled.
