Jurisdiction and admissibility in investment arbitration:The practice and the theory

Abstract This is the first half of a two-part essay on jurisdiction and admissibility in investment arbitration. It focuses on the arbitration practice, whilst the second part sets these concepts in the wider framework of public international law litigation. This essay maps the objections to the tribunal’s jurisdiction (by ratio: materiae, temporis, loci and personae) and the claim’s admissibility. It offers some preliminary conclusions: in certain areas there still is no consensus; tribunals are inclined to characterise objections as jurisdictional, and rarely resort to admissibility; findings of inadmissibility draw a judgment on the claimant or the claim’s propriety (whilst jurisdictional decisions typically eschew value-judgment); tribunals failed to distinguish jurisdiction from admissibility. These findings are further explored, within a wider theoretical context, in the second part of the essay.</jats:p

Jurisdiction and admissibility in investment arbitration:A view from the bridge at the practice

The jurisdiction of international courts and tribunals and the admissibility of inter-State claims under international law are central to international adjudication, operating as a gateway to the litigation on the merits – the end goal of the proceedings. Still, these concepts remain inherently under-defined, and can be shaped in multiple ways to formulate preliminary objections in international litigation in general. International investor-State arbitration adds specific aspects and complexities to the issue. This introductory contribution accounts for the theoretical deficiencies underpinning the notions of jurisdiction and admissibility, with a special focus on international investment arbitration, and introduces the selected case-studies which form the subject-matter of the articles in this Special Issue. The recent Urbaser award is also used as an example of the unexplored potential of novel – and critical – legal argumentation relating to the jurisdiction of investment tribunals
