        Abstract


This article surveys selected decisions of international criminal courts and tribunals,
and related literature, examining custom from a general standpoint. This article con-
siders the place and nature of custom, with a particular focus on challenges levelled
against custom's suitability in international criminal law. This article also analyses cus-
tom's 'structure, and, more specifically, the application of the 'two-element approach'
by international criminal courts and tribunals. This articles then discusses claims
that international criminal courts and tribunals engage in sui generis customary law-
making, and revisits the distinction between custom inforo and in pays, examining
that distinction's pertinence to assessing such claims. Having emphasised the influ-
ence of general international law on international criminal law, this article lastly re-
verses its focus, and addresses custom's wider functions as source for rules on custom's
identification and, more generally, other sources' recognition, showing how some deci-
sions of international criminal courts and tribunals elucidate those wider functions.
