Abstract

The general assessment of the problem of the use of previous decisions in international adjudication usually starts from the many statements to the effect that ‘there is no rule of precedent in international law’. Reliance is mainly placed on specific statutory rules, starting from Article 38(1)(d) of the Statute of the International Court of Justice (ICJ), which is understood to authoritatively reflect the sources of international law and states that the Court ‘shall apply... judicial decisions’ as ‘subsidiary means for the determination of rules of law’ subject to the operation of Article 59, which appears to rule out any endorsement of a rigid rule (or practice) of stare decisis. These approaches have a common thread: they address the question of the use and authority of previous decisions in international adjudication as one regulated by rules. Yet, they are never found to provide a satisfactory answer to the problem. This chapter offers an alternative to the traditional outlook, challenging the oft-repeated truism that ‘there is no rule of precedent in international adjudication’ by arguing that it is desirable to shift the analysis from an almost mythological rule of precedent—or an equally esoteric belief of a lack thereof—to more tangible rules on precedent. These may include—and do include—rules in which a specific understanding of the question is endorsed by the statutory provisions of a specific international adjudicator, but are not exhausted by them, as other rules of different nature and origin (including, but not limited to, organisational directives, rules on submissions, on evidence and on law- ascertainment, as well as those concerning systems of challenge, appeal, and control) also have an impact—with various degree of directness—on the role, possible uses, and authority of the past. This study is based on the identification of such rules and their treatment. Its overall purpose is to show how, in the absence of one rule of precedent, the many rules on precedent can contribute to shape the use of the past by international adjudicators, and their mindset in doing so. The approach taken in this study is based on the examination of existing or purported rules, and thus is both rule-based and aimed at rule- synthesis. It is not, however, merely descriptive: rather, it also considers the implications, which could found use for the creation of new adjudication mechanisms and provides insights on potential avenues of reform.
