Despite the growing recognition of representation as a fundamental principle in global governance, the ICJ Bar continues to exhibit pronounced gender imbalances. This study adopts an empirical frame of reference to scrutinise the gender and professional composition of legal teams appearing before the ICJ over the last decade. It involves a systematic examination of oral proceedings in contentious cases before the Court between 2013 and 2023, breaking down the gender and professional role of counsel for each party in every case. The manifest invisibility of women in international courtrooms challenges the perceived neutrality of the international legal system and raises the question; is international law gendered? This article posits that the predominance of male and academic perspectives delimits the interpretation and application of international law as issues and viewpoints that could strengthen the adjudicatory process are at risk of being overlooked. Thus, the findings herein seek to contribute to a nuanced and holistic discourse that not only informs academic scholarship, but also empowers practitioners to navigate the complexities of the ever-evolving international legal order. The integration of representative voices and heterogeneous perspectives in representations to the Court is a cornerstone of a legitimate, equitable, and effective international system. This article calls for a concerted effort by the international community to diversify the faces of ICJ advocacy.
