As investment and trade develop, disputes will be more diverse. Looking back at history, the International Center for Settlement of Investment Disputes (ICSID) only registered 28 ISDS cases during the first two decades after its establishment. In contrast, there have been 38 cases registered at the ICSID in the year 2014 alone. The substantive issues of disputes have become more diverse, and therefore a wider range of expertise is needed to solve the disputes.
One cannot perceive how future disputes will look like and what expertise will be required. At the same time, the quality of ISDS outcome needs to be ensured. The current practice has served this purpose by allowing parties to the dispute and/or arbitration institutes to appoint arbitrators from a broad range of expertise, as opposed to a pre-determined list.
Let’s look at some of the cases. In Glamis Gold v. USA, the tribunal had to decide whether a requirement to conduct a certain mining technique had constituted an indirect expropriation. This case required expertise to assess the value of the mining project, including evaluation of mineral price. In fact, the tribunal contributed 100-page analysis only on this issue.
In another case, Methanex v. USA, the tribunal was faced with lengthy submissions from parties on whether or not a certain chemical for fuel production was dangerous for the environment. In addition, there have been other complicated disputes on, among other things, electricity pricing and gas pricing. The above cases are only small part in the big pool of ISDS cases which requires specific expertise.
The current system of arbitrator’s appointment has made international arbitration able to adapt with the present needs of dispute resolution. Most importantly, it can keep up with the trade development. It is therefore unwise to replace this important feature with a pre-determined list of arbitrators.
