Mexico Country Visit of the Working Group in September 2023

Spotlight regularly features a significant individual or team from the Human Rights Community to answer questions put by students and colleagues from the University of Essex. This time we feature Dr. Matthew Gillett.

Dr. Gillett was appointed as a United Nations Special Mandate Holder in 2022. Specifically, he is the Expert Member from the Western Europe and Others Group in the Human Rights Council’s Working Group on Arbitrary Detention. In 2023, he was elected Vice-Chair for Communications of the Working Group. In this role, he cooperates with other Special Mandate Holders (typically the Special Rapporteurs on Torture, on Extra-judicial Killings, and on Counterterrorism, plus the Working Groups on Forced Disappearance and on the Elimination of Discrimination against Women and Girls); to issue communications to Governments and other entities (such as corporations) regarding potential human rights violations. As a member of the Working Group on Arbitrary Detention, he deliberates around 80-90 judgments (called opinions) a year and also conducts country visits to scrutinize detention practices around the World.

Previously, Dr. Gillett has around 15 years of experience working in international organisations in The Hague (particularly as a prosecution attorney at the International Criminal Court (“ICC”) and the International Criminal Tribunal for the former Yugoslavia (“ICTY”)). He has conducted investigations in various conflict zones, including for six months as a Human Rights Officer with the United Nations Assistance Mission in Afghanistan (“UNAMA”). 

Academically, his work encompasses: International Criminal Law; Human Rights; Terrorism and Counterterrorism; Procedure and Evidence; Open-Source investigations; the Environment; International Humanitarian Law; Mediation (as a qualified mediator); Speech Crimes; and Aggression. His publications have been cited before international and hybrid courts, including in filings and Decisions of the Colombia Special Jurisdiction for Peace (“Pre-Report on Charging Environmental Damage before the Jurisdicción Especial para la Paz”); the International Criminal Court (e.g. “Collective dislocation; crimes of displacement, property depravation and discrimination under international criminal law”, Routledge; “The Call of Justice: Obligations under the Genocide Convention to Cooperate with the International Criminal Court”, CLF) and the Special Tribunal for Lebanon (e.g. “Fast-Track Justice”, JICJ; “The Special Tribunal for Lebanon Swiftly Adopts Its Rules of Procedure and Evidence”, JICJ).

Students’ and colleagues’ questions answered

We are honoured that Dr. Gillett agreed to answer questions put by the human rights students and community at Essex.

Q: What initially drew you towards human rights?

A: Working at the High Court of New Zealand exposed me to various human rights cases, from freedom of expression claims to complaints of ill-treatment in detention. Learning about the substance of human rights, and the effect of international conventions on the application of domestic law was fascinating. 

Q: How do you believe the efforts of the Working Group on Arbitrary Detention can help address criticisms of the UN’s human rights work?

A: The Working Group on Arbitrary Detention strives for fair conclusions and innovative ways to enhance human rights compliance. One of the important ways we can reduce criticism is through robust fact-finding. We have five expert members, with a range of experiences and backgrounds. Our individual cases are subjected to rigorous review, while also ensuring that we address a high volume each year. We also travel to countries to assess their detention systems and meet with detainees, officials, and NGO representatives, all of which helps us to reach well-grounded findings. 

Q: What advice would you offer aspiring human rights workers?

A: Gain field experience early, explore alternative avenues for redress, and follow up on cases to understand their outcomes comprehensively. In more detail: (i) Get field experience at an early stage – it will open your eyes to the situation on the ground and whether you are well suited to that type of work. (ii) Think about your options in any situation, such as new avenues or fora to redress a human rights violation, and don’t simply accept binary choices that are presented to you. (iii) Follow-up on situations you have been involved in – if you assisted a victim with a human rights claim, then get back in contact periodically afterwards to find out how it panned out. 

Q: How can we assess the effectiveness of human rights measures such as issuing communications?

A: Tracking responses and subsequent actions by governments is essential. Effective engagement with international bodies like the UN can amplify pressure for change. An obvious case is if the Government or entity in question explicitly changes their conduct as a result of the communication. However, in many cases that won’t happen, at least not instantly. So the first step is keeping a track of communications and responses, the second is assessing to what extent the response engaged with the issues, and the third is considering follow-up measures such as public statements or bringing pressure through international fora like the United Nations Human Rights Council or General Assembly. 

Q: Considering the allegations against the US and UK regarding torture in Iraq and Afghanistan, and their reluctance to allow ICC investigation or hold themselves accountable, what message do the actions of powerful states convey regarding accountability for human rights violations?

A: Reluctance to engage with international institutions sends a discouraging message globally, undermining the universality of human rights principles. Just like international human rights law, international criminal law is designed to apply universally. The lack of commitment to institutions like the International Criminal Court by powerful States including Russia, China and the USA sends a dispiriting message to the people of the world – especially given that the crimes listed in the Rome Statute, such as aggression, genocide, crimes against humanity and war crimes are lowest common denominators, which all States should agree to prohibit.

Q: What are your concerns regarding the existing framework of the working group, and how can it be improved?

A: Balancing increasing caseloads with broader advocacy efforts poses challenges. For the future, it would be ideal to have increased resources for the OHCHR team which supports the expert members of the Working Group. 

Q: In your role as Vice-Chair for Communications of the Working Group, what strategies do you employ to foster collaboration among Special Mandate Holders and issue effective communications to address potential human rights violations? 

A: Collaborating with other Special Mandate Holders is a highlight of the work, but of course can present its own challenges in terms of coordination. Typically, a strategy is to have a lead mandate in charge of a particular communication, and then others to review and sign onto it. We have also started having more regular meetings and exchanges on particular hot-spots which raise issues for multiple mandates, so that we are communicating with each other and exchanging information and views in order to enhance our understanding of the situation.

Q: Having worked as a prosecution attorney at the ICC and the ICTY, how do you draw on your experiences in conflict zones to contribute to the Working Group on Arbitrary Detention? 

A: As a former prosecutor, I am used to looking through statements, documents and other sources to reach factual conclusions. Having worked in multiple situations of armed conflict, I am aware of security requirements but also know the importance of seeing situations and speaking to people first-hand to establish events. Additionally, there is considerable overlap between arbitrary detention and the crimes I prosecuted, which helps for legal assessments. 

Q: Can you share insights from your academic work and its relevance to human rights advocacy?

A: My research has recently focused on fact-finding. This has spurred me to look at the procedures employed at various human rights bodies, and what types of materials they base their findings on. Legally, the context of armed conflict or terrorism type scenarios helps to understand when there may be different considerations to bear in mind when assessing the application of international human rights law.

Q: Given that your work exposes you to stressful and harrowing experiences and stories, how do you cope with these challenges? 

A: When I am interviewing a victim or visiting a crime scene, my focus is usually on forensic details and ensuring an accurate record, as well as the safety of everyone involved. However, I realised after many years of working long hours that you have to look out for your own well-being as well. Now I exercise reasonably often and enjoy catching up with friends and colleagues from around the world when the opportunity arises. I also have two young children to keep me on my toes.
