Might contain traces of Lotus: The limits of exclusive flag state jurisdiction in the Norstar and the Enrica Lexie cases

The article scrutinizes some of the surprising commonalities in the reasonings of two recent decisions by two separate judicial forums: the ITLOS’s judgment in the M/V Norstar case and the award of an ad hoc arbitral tribunal in the Enrica Lexie case. One key connection between the two decisions is their heavy reliance on the Lotus judgment of the PCIJ. Another similarity between the two disputes is that both of them revolve around the concept of exclusive flag state jurisdiction under UNCLOS Article 92(1) and adjacent questions of jurisdiction on the high seas. The article is going to subject both decisions to criticism and argue that some of the more problematic positions adopted by the tribunals in both cases amount to no more than obiter dicta – thus establishing an additional parallel with Lotus, which also received heavy criticism for its controversial obiter dictum. The two tribunals’ new-found interest in Lotus also provides an opportunity to discuss the utility and legal weight of Lotus as a precedent in the face of a century of developments in treaty law and judicial practice. In this sense, this article builds on and attempts to continue the recent trend in scholarship advocating for a renewed appreciation of the Lotus case against the backdrop of decades of criticism against it. Accordingly, the article aims to facilitate a better understanding of all three disputes, the principles they applied, and the dynamics of international adjudication and international law in general.
