Monica Feria-Tinta

Call: 2014

Languages: Spanish (fluent); French (fluent); German (intermediate)

Monica is a specialist in public international law. Her practice covers the full spectrum of public international law including statehood, treaty interpretation, state responsibility, immunities, law of the sea, boundary delimitation, transboundary environmental damage, environmental law, investment law, UN law, self-determination, human rights, use of force, international humanitarian law and international dispute settlement.

Her practice also covers private international law, international arbitration and public law, with an emphasis on human rights.

Monica acts as counsel in cases before English courts, international courts and arbitral tribunals under a variety of rules and applicable laws. She has appeared or advised before the International Court of Justice (ICJ), Permanent Court of Arbitration (PCA), International Tribunal for the Law of the Sea, UN Human Rights Committee, Inter-American Commission on Human Rights, Inter-American Court of Human Rights, ICSID and SIAC tribunals, International Criminal Tribunal for ex-Yugoslavia (ICTY), UN Special Rapporteurships and diplomatic fora. Monica is admitted to practice before the ICC. She is currently sitting as Arbitrator (Chair) in an investment arbitration with a seat in The Hague.

She brings a wealth of international law experience to her practice, and thorough knowledge of procedural and substantive law of international tribunals, having worked for the ICJ and the ICTY (Chamber Trial I) prior to the Bar. Her experience working with international law institutions includes assisting members of the International Law Commission (ILC) drafting comments to the ILC Draft Articles on State Responsibility, acting as Amicus (with the ILC Special Rapporteur on Diplomatic Protection); drafting responses relating to UN Special Procedures; acting as expert to the Final Report of the Independent Expert on the right to reparation for victims of gross violations of human rights and humanitarian law; assisting drafting UN General Assembly Resolutions (in an advisory capacity); and serving as legal adviser to a State Delegation to the Diplomatic Conference that negotiated the Rome Statute and established the ICC. She has also served as Assistant Legal Adviser to the Foreign and Commonwealth Office.

Monica’s recent practice in international law includes advising on cases arising from Kosovo (peace-building operation), Syria, Iraq, Somalia and Iran. She is currently advising on complex aspects of sovereign state immunity in England and Wales. In arbitration, she has recently advised on state attribution in the context of construction contracts in an ICSID claim. She is also acting in inter-state litigation raising novel aspects of international law, in the area of the law of the sea. Monica’s expertise in this area of law is reflected in her recent appointment to the IUCN World Commission on Environmental Law (Oceans, Coasts, and Coral Reefs Specialist Group).

She has published extensively in the area of public international law and her work has been cited in ICJ proceedings and by Lord Carnwath of the UK Supreme Court. She is the author of the forthcoming book Foreign State Immunity and Enforcement of Arbitral Awards in English Courts to be published by Oxford University Press. Monica has lectured worldwide on public international law including as guest lecturer at Oxford University; Kurt Bosch-University of Fribourg, Switzerland; Guangxi Normal University, Faculty of Law, China; Georgetown University Law Centre; and Universidad Autónoma de Mexico. She has held academic positions at the Lauterpacht Centre for International Law (University of Cambridge) and at the LSE (as Teaching Assistant to HE Christopher Greenwood, former ICJ Judge).

Monica has taken part in expert missions to Guatemala (2015), Myanmar (2016), and has trained advocates in South Africa on international law, Colombian lawyers on judicial processes in the context of transitional justice, and members of the Bar in Honduras on international arbitration.

She accepts appointments as arbitrator in ICSID, PCA, ICC and LCIA cases. She has been appointed to the Equality and Human Rights Commission’s Panel of Preferred Counsel (B-Panel) who are generally instructed where “substantial knowledge and experience is required” in cases of great public importance concerning Equality Act 2010 and human rights breaches in litigation before domestic and European Courts.
