Most international organizations have a spokesperson or press office of some sort. That office is responsible for the official messaging of the organization and for communicating to the world what the organization is doing. Readers can often gather official policy statements and other announcements from such an office. For organizations committed to transparency, these offices sometimes go beyond standard statements and facilitate engagement with the organization and public access for the benefit of multiple constituencies. The World Trade Organization (WTO) is one of the international organizations with such an office, and by most assessments, the office is both busy and effective in communicating about the diverse, multifaceted work of the WTO.

But most organizations would likewise benefit from having a Gabrielle Marceau among their ranks. Gabrielle has served an incredible role in her many years at the WTO: that of being both attuned to the external conversations as well as appropriately thoughtful about internal conversations concerning the WTO’s work. This is not to say that Gabrielle spoke out of turn or superseded the press office in any respect. Quite the opposite. Gabrielle always knew and respected the limits of her work at the WTO. What has been unique about her dual capacities as academic and practitioner at the WTO has been her thoughtful ability to engage across both communities.

For this reason, Gabrielle’s voice and participation in the international economic law and policy space are unparalleled. Her work has provided a bridge to help academics and outsiders understand this complex organization and body of law and to help practitioners engage with academic substance. Her capacity to manage those relationships and to communicate effectively among the groups is laudable. That is why more organizations need a Gabrielle. If more international organizations could benefit from having someone on their staff who could seamlessly conduct academic research while also serving the institution, the international law scholarly and practitioner communities would be far better off. Institutions profit when their people are out and about engaging and likewise the academic community is enriched by their engagement.

But the fact of the matter is that there is no one quite like Gabrielle. As a professional matter, with a career spanning over three decades, Gabrielle is impossible to replace. No one rivals her depth of experience alongside her academic contributions in international economic law and policy. Her work is also responsive to the moment. She has expertise in institutional, procedural, and substantive dimensions. Whether writing about the people,<fnref n="1" /> the changing legal landscape,<fnref n="2" /> or thinking about the future of the international economic order,<fnref n="3" /> among many other topic areas, Gabrielle has thoughtfully contributed in so many respects to the body of international trade law in particular, and increasingly beyond.

The same could be said about Gabrielle personally. It is hard to recall when I first met Gabrielle because she is everywhere all the time. She also carries a warmth and projects a familiarity that makes you always feel like you have known her for years. With all her interlocutors, she appears to value every interaction—whether you are a student, junior colleague, or senior colleague. Her treatment of all as equal is notable and deeply appreciated in a field of hierarchy.

I have especially valued Gabrielle’s engagements at multiple conferences and in her capacity as a member of the Journal of International Economic Law Editorial Board, a publication for which I have served as co-Editor-in-Chief since 2021. My co-Editors and I have greatly appreciated Gabrielle’s many roles with respect to the Board, whether as a reviewer, commentator, or other contributor to Board governance.

Finally, I want to thank Gabrielle for her thoughtfulness. She has been so generous to open her home in Geneva to host international law events. She has supported students and junior colleagues along so many dimensions. We should all be especially grateful to Gabrielle for all that she has done in big ways and in small. I wish her a wonderful retirement, and I look forward to continuing our many conversations on trade and non-trade topics in the coming years.
