The 2014 judgment of the International Court of Justice, regarding Whaling in the Antarctic, brought into focus scientific fact-finding in disputes before the Court. This article examines the Court's practice with respect to first, the mode of appointment and method of examining experts assisting the Court in fact-finding; and second, the standard of review employed in analysing a scientific fact to arrive at a judicial decision. In doing so, the article also refers to jurisprudence of the World Trade Organization to draw parallels and best practices therefrom. This analysis is aimed at structuring a coherent and predictable approach for scientific fact-finding before the International Court of Justice.

My answer is in the negative. First, it is not for the expert to weigh the probative value of the facts, but to elucidate them and to clarify the scientific validity of the methods used to establish certain facts or to collect data. Secondly, the elucidation of facts by the experts is always subject to the assessment of such expertise and the determination of the facts underlying it by the Court. Thirdly, the Court need not entrust the clarification of all the facts submitted to it to experts in a wholesale manner. Rather, it should, in the first instance, identify the areas in which further fact-finding or elucidation of facts is necessary before resorting to the assistance of experts.’
