Megan Hirst practices in international criminal law, and international human rights law. She has over 15 years of experience in international institutions and courts, with a particular focus on victims’ representation and the post-conflict protection of human rights.

Although Megan has significant experience in various aspects of international criminal proceedings, she has a particular interest in victims’ representation before international criminal tribunals. From 2019 until 2022 she was International Lead Co-Lawyer for victims participating as civil parties in Case 002/02 at the Extraordinary Chambers in the Courts of Cambodia. At the International Criminal Court (ICC), she is representing victims in pre-trial proceedings concerning crimes against the Rohingya in Myanmar, and the opening of an ICC investigation on Afghanistan. She has also previously represented victims in the ICC case against Dominic Ongwen, a former LRA commander in the conflict in Northern Uganda. Previously Megan worked in-house for both the ICC and the Special Tribunal for Lebanon on victims’ participation issues, in which capacity she undertook litigation and played a key role in the development of polices and legal frameworks.

Outside of victims’ representation Megan’s international criminal work has included post-conviction litigation before the United Nations Mechanism for International Criminal Tribunals and advising the Registry of the Special Tribunal for Lebanon on a range of issues including immunities and international administrative law.

Megan also has experience advising on questions of public international law and international human rights law, in relation to litigation before both international bodies (such as the UN Special Procedures and Treaty Bodies) and domestic courts.

Megan’s domestic practice has focused on children’s rights. Together with Caoilfhionn Gallagher QC, she represented more than 45 complainant core participants before the Nottinghamshire Councils strand of the Independent Inquiry into Child Sexual Abuse. She has also represented child claimants in community care and age assessment cases.

In addition to her work as counsel, Megan regularly leads international projects relating to human rights and rule of law development. She has particularly extensive experience in policy development and capacity building work in the East Timor, where she has worked since 2005. Her work there focuses on responses to historical mass atrocities and the strengthening of the justice sector. She also works regularly with local organisations focused on strengthening judicial responses to domestic and sexual violence in East Timor.

Megan is widely published on issues relating to international criminal justice and human rights. She co-edited the leading book on the law of victims’ participation in international criminal tribunals, published in 2017.
