In the European Union businesses, consumers and workers all enjoy the benefits of the Single Market. The Single Market rules ensure that there are no internal frontiers for people to work, live, study and do business within the EU. However businesses and citizens also often run into trouble because of the incorrect application of EU Single Market rules by public authorities of the EU Member States. For that purpose, the Commission launched an informal network named SOLVIT in 2002. Despite being almost old enough to buy a drink in a pub, not everyone is aware of SOLVIT’s existence, nor of what it does. A lack of (effective) promotion is most likely the cause of this problem. Therefore, this post is meant to offer some clearance on how SOLVIT functions in practice, while also dwelling upon some success stories.
