Stephanie Regalia

Stephanie Regalia studied English law and French law at King’s College London and Université Paris 1 Panthéon-Sorbonne. She completed a dual master’s degree in Energy & Environment at Sciences Po and Columbia University School of International and Public Affairs, where she was the project manager of the 2017-2018 Business & Human Rights Clinic. Prior to joining the IDP Business and Human Rights, Stephanie worked at the Business and Human Rights Centre and trained as a lawyer in France.

Stephanie is conducting her doctoral research project under a cotutelle agreement with Université Paris 1 Panthéon-Sorbonne. Her research analyses the nature of corporate human rights due diligence obligations, as they appear in national legislations, including the French Duty of Vigilance Law, the German LkSG and the EU CSDDD. By identifying the existence of ‘effectiveness requirements’, i.e., the obligation for companies to assess and prove the effectiveness of their due diligence measures, this research project questions the traditional understanding of the business obligation under these laws as focusing on process alone, as opposed to the result. The project includes a comparative analysis of effectiveness requirements as they appear in international human rights law and national anticorruption compliance regimes, and proposes a classification of corporate human rights due diligence obligations along a conduct-result spectrum of obligations.
