Called: 2018
Qualified to accept Public Access instructions

Miriam is a Barrister practising in international crime, human rights law, public international law, environmental law, and international arbitrations. She advises individuals, governments, NGOs, and international law firms.


Miriam is currently employed by ClientEarth to assist with litigations in courts in the UK and abroad. During this time, she is unable to be instructed through Chambers.


Current work

In criminal matters, Miriam acts for the defence and the prosecution.


At the Kosovo Specialist Chambers in The Hague, Miriam is instructed to defend Nasim Haradinaj, a former Kosovo Liberation Army fighter and vice president of the KLA War Veterans’ Association, accused of distributing allegedly confidential documents pertaining to war crimes investigations, thereby obstructing the course of justice. Miriam is also advising a suspect under investigation by the Specialist Prosecutor’s Office in proceedings challenging his continued investigation. Miriam’s responsibilities have ranged from drafting legal submissions (including appeals), to setting out cross-examination roadmaps for trial, and interviewing witnesses in Kosovo.


At the People’s Tribunal for the Murder of Journalists, Miriam is assisting the Lead Prosecutor, Almudena Bernabeu and her advisor Sir Howard Morrison KCMG CBE QC. She works closely with the NGO Free Press Unlimited. The People’s Tribunal, a process initiated by non-governmental organisations, seeks to establish whether the Mexican, Sri Lankan and Syrian authorities committed breaches of international law by failing to investigate three journalists’ killings.


Miriam is also part of a team of Guernica 37 barristers advising the government of the Netherlands on bringing a case before the International Court of Justice against Syria for violations of the United Nations Convention against Torture. Miriam has also advised another government on specific requirements and hurdles for bringing a case under the Genocide Convention.


Independently, Miriam has been instructed to advise a leading Dutch international arbitration firm on matters of English law.


Previous experience

Prior to coming to the Bar, Miriam was a Judicial Assistant at the International Court of Justice and a lawyer in the International Arbitration Group of WilmerHale LLP for three years. 


At the International Court of Justice, Miriam worked with Judge Sir Christopher Greenwood GBE CMG QC, Judge Kirill Gevorgian and his predecessor Judge Leonid Skotnikov. Miriam assisted the British and Russian judges with legal research and drafting in relation to inter-state cases brought under the Genocide Convention, as well as regional and bilateral treaties. After the ICJ, Miriam worked at the United Nations Office of Legal Affairs in New York as part of the Mercator Fellowship on International Affairs.


At WilmerHale LLP, Miriam worked on international investment arbitrations at the International Centre for Settlement of Investment Disputes (ICSID) and international commercial arbitrations under various rules (UNCITRAL, LCIA, DIS and NIA), including enforcement proceedings in the Dutch Supreme Court. Miriam also advised on public international law, international sanctions, international trade law, including disputes before the World Trade Organization, and EU law. 


Miriam also gained experience acting pro bono for a Defence team at the International Criminal Court and as an Employment Law Volunteer for the Free Representation Unit. 

During her legal studies, she held legal research positions at the British Embassy The Hague and in academia (at the universities of Cambridge and The Hague). She worked on law journals (as a Managing Editor of the UK Supreme Court Yearbook and an Editor of the Cambridge Journal of International and Comparative Law) and interned at international courts and tribunals (ICC, ICJ and ICTY).
