Can’t Fight the Moonlight? Actually, You Can: ICJ Judges to Stop Acting as Arbitrators in Investor-State Disputes

The earthquake started in earnest in November 2017. At its epicentre was a report, published in November 2017 by two researchers at the International Institute for Sustainable Development (“IISD“).

In the report, titled “Is ‘Moonlighting’ a Problem? The role of ICJ Judges in ISDS”, researchers Nathalie Bernasconi-Osterwalder and Martin Dietrich Brauch analysed the contents of several public databases of ISDS cases, and found that at least seven judges at the International Court of Justice (“ICJ” or the “Court“) at the time of publishing (and 13 former judges) had worked (or were working at the time of the report) as arbitrators in treaty-based investor state dispute settlement cases during their terms at the ICJ.

Crunching the numbers further, the two IISD researchers looked at the amount of treaty-based cases in which ICJ judges had served as arbitrators. They compared the number against the 817 treaty-based ISDS cases known as of July 2017. The results were surprising: ICJ judges had sat as arbitrators in roughly 10% of all known investment treaty cases during their tenure.

This raises three types of concerns.

First, it seems to contravene the prohibition for ICJ judges to “engage in any other occupation of a professional nature” contained in the Statute of the International Court of Justice (the “ICJ Statute“).

Second, arbitrators are usually paid according to the time (calculated in days or hours) spent working on a case. This means that any ICJ judge who is also appointed as an arbitrator would have an economic incentive to spend more time on the investment treaty case, to the potential detriment of the judge’s Court-related work.

Third, cumulating the roles of ICJ judge and arbitrator (or, as the report called it, “moonlighting”) could potentially impact, or be perceived to impact, the judge’s independence and impartiality. Read the rest of this entry…
