Abstract Avoiding lis pendens within the EU has always been considered a guarantee for effective judicial cooperation. However, since arbitration is excluded from the scope of European procedural law, questions have been raised as to how parallel arbitral and state court procedures will be regulated. This article aims to illustrate the mechanisms that have been proposed to resolve this issue outside the European Regulations’ scheme with a focus on parallel arbitrations. Under this scope, the author attempts to discuss the potential solutions that have been introduced in respect to “lis pendens” between an arbitral tribunal and a state court as well as their effectiveness. Taken the tie from this analysis, the last part of this article focuses on the issue of parallel arbitral procedures and whether conflicts of jurisdiction can be resolved by using the same mechanisms as adopted in the case of parallel the arbitral and state court proceedings.
