It is no secret that the European Union law can be characterized by different degrees of integration, all depending on the policy area involved. EU competition law is one of the most integrated areas, with very well established jurisprudence. Time to time, the European Commission, the executive authority in this field of law, issues non-binding legal acts, notices & recommendations, with the pursuit of explaining the law. The role of these acts is an advisory one and the interpretation of law expressed by these Commission documents is, of course, built on the jurisprudence of the EU Courts. The Commission, by publishing and distributing its view of the law, in the form of non-binding legal acts, it creates certain expectations and therefore it is obliged to act accordingly to them. It may create the expectation that a certain type of behaviour is not anti-competitive by its object, or that an undertaking within certain thresholds will not be subject to any allegation concerning an infringement of a specific provision.
In a recent Opinion to a pending case, Expedia Inc, the AG Kokott has maintained that the national authorities and Courts are also obliged to respect the Commission's view of the law, expressed by its Recommendations and Notices., because a different conclusion will lead to an infringement of the general principles of law, foremost:
* the principle of equal treatment
* the principle of duty of sincere cooperation
* the principle of legal certainty
* the principle of level playing field
* the principle of uniform and effective application of EU law.
See points 36-38 in the Opinion attached hereby.
The result can be that a non-binding act becomes 'binding' due to the fundamental pursuit of preserving the respect for general principles of EU law. The national authorities and court are though allowed to adopt a divergent view, if they can justify it and this justification can be judicially reviewed.
This equation could be translated into:
Soft law + Union exclusive competence + Preservation of general principles of EU law = Binding law
