messages.role: assistant
messages.content: Ben Emmerson QC is a British barrister and human rights lawyer who has worked extensively in the field of international law. He served as the United Nations (UN) Special Rapporteur on the promotion and protection of human rights and fundamental freedoms while countering terrorism from 2014 to 2018.
  
  In his role as Special Rapporteur, Emmerson did not directly lead the UN Working Group on Arbitrary Detention (WGAD), but he did engage with the WGAD's work in various ways. The WGAD is an independent body of five human rights experts that investigates allegations of arbitrary detention around the world.
  
  Emmerson's work intersected with the WGAD's mandate, particularly in relation to counter-terrorism measures and their impact on human rights. He often referred to the WGAD's opinions in his reports to the UN Human Rights Council, emphasizing the importance of the WGAD's work in ensuring that detention is carried out in accordance with international law.
  
  For example, in his 2015 report on the human rights impacts of drone strikes, Emmerson cited the WGAD's opinion on the arbitrary detention of individuals who were killed in drone strikes, stating that such killings could constitute a violation of the right to life and the prohibition against arbitrary detention.
  
  In addition, Emmerson has also served as a member of the WGAD in the past. According to the WGAD's website, Emmerson was a member of the Working Group from 2001 to 2004. During his tenure, he contributed to the WGAD's work on numerous cases of alleged arbitrary detention, including cases involving individuals detained in Guantanamo Bay, Iraq, and other countries.
  
  Overall, while Ben Emmerson did not directly lead the UN Working Group on Arbitrary Detention, he has had a significant relationship with the WGAD through his work as a Special Rapporteur and a former member of the Working Group. His work has often intersected with the WGAD's mandate, and he has emphasized the importance of the WGAD's work in ensuring that detention is carried out in accordance with international law.
