Eco Swiss leaves a very mixed impression. On the one hand, the factual implications of this case for arbitration might, after all, appear not so dramatic in practice. The ECJ has firmly demonstrated that it follows its precedents associated with a more self-restrained approach towards national procedural autonomy, at least as far as procedural restrictions in arbitration-related areas are concerned. Furthermore, the Court did not travel the more precarious path between the two suggested by the Advocate General. At present, one can only speculate about the repercussions for arbitration which the judgement would have inflicted, had the Court engaged in analysing the arbitrators' duties and powers to apply EC law or the extent of the supervisory functions of national courts in arbitration matters.
