Monica has a keen interest in conflict of laws and extra-territorial torts. In particular, in cases raising issues of corporate liability for extra-territorial torts and cases alleging corporate complicity in human rights violations and/or environmental harm. Her public international law background enables her to effectively deal with act of state doctrine arguments in the context of extra-territorial violations. Her developing expertise in this area of law is reflected in her speaking engagements which includes being a panellist on “Parent Company Liability in English law” at the 2018 UN Forum Business & Human Rights at the UN Headquarters in Geneva.

Her dual training in the common law and civil law systems allows her to be comfortable handling cases arising from common law and civil law jurisdictions. Originally trained as an advocate in Latin America, and with over 15 years’ international experience in the region, Monica has particular interest in representing cases arising from Latin American jurisdictions. Her ability to handle evidence in the technical, legal, native language, has come as an advantage in her practice, especially in the representation of cases where the applicable law may be foreign law.

Example cases:

• Bravo and others v Amerisur Resources plc [2020] EWHC 203 (QB),(for defendant) (Colombia/UK) acted in this claim for economic and non-economic damage allegedly caused by environmental contamination and pollution of land and waterways by oil spill (oil & gas).

Monica made a substantial contribution to the private international law arguments which secured Actavis winning its case on private international law, as the Court of Appeal concluded that the conditions for negative declaratory relief are procedural and governed by the lex fori under Rome II in its judgment, the lead judgment on this aspect of the new Rome II Regulation.

She is a member of the Chartered Institute of Arbitrators and has recently been listed on the panel of arbitrators of SCC, ICC, and CRECIG (Comisión de Resolución de Conflictos de la Cámara de Industria de Guatemala).

Monica started her arbitration practice as assistant in commercial and investment arbitrations to renown Arbitrator Julian Lew KC.   Monica is a member of the Chartered Institute of Arbitrators and has been a guest lecturer at the LCIL Executive Course on Investment Law and Arbitration, University of Cambridge.

Monica is currently in the UK-Korea FTA and UK-Japan CEPA dispute resolution lists of arbitrators (proposed by the UK) and was appointed by the government of Malaysia to the Advisory Council of the Asian International Arbitration Centre (AIAC).   Monica’s experience as arbitrator includes:

• SCC Arbitration (2018-2021) – President of a three-member tribunal in a €1.2 billion+ claim investment arbitration with a seat in The Hague in the renewables sector
• LCIA Arbitration – Arbitrator (three-member tribunal), appointed by the LCIA, in an USD $70 million+ commercial dispute under several agreements for the supply of oil (several arbitrations consolidated in one single arbitration proceedings), under English Law, with a seat in London.

Monica brings to the Bar over 20 years of award-winning international litigation experience in human rights cases.

Her human rights practice is international. She acts before the European Court of Human Rights, the Inter-American System and more recently, the African system, as well as before UN Human Rights Treaty-based-bodies (Committee Against Torture), UN Human Rights Committee, CESCR, CEDAW, CRC) and Charter-based bodies under Special Procedures). She is also increasingly being instructed to act/advise on cases before foreign courts (East African Court of Justice, Hong Kong Court of Appeal, Constitutional Court of Ecuador, Supreme Administrative Court Colombia, Supreme Court of Mexico).

Her human rights litigation work covers the full spectrum of human rights: from security of person, the right to privacy, non-discrimination and due process (on civil, administrative and criminal cases) to the rights of the child, gender justice, prisoners’ rights and the protection of the right to life and freedom from torture in the context of mass atrocities. Whereas some of the issues she has dealt with have arisen from societies in times of peace, she has wide experience litigating human rights violations taking place in the context of armed conflicts and states of emergency. Monica is very experienced in the investigation of violations of the right to life in the context of counterinsurgency operations, police operations, death under custody and crowd control, and expertise in dealing with cases of mass violations of the right to life of civilians based on alleged direct participation in hostilities. She has experience working with complex forensic evidence requiring specialised knowledge on a wide range of weapons, ammunition and gases (i.e. white phosphorous cases) and their impact on human targets both in closed and open environments.

She has extensive experience dealing with large-scale cases of torture and its investigation under international standards. Her mastering of fair trial standards permitted her to advice the Foreign & Commonwealth Office said standards, and guidance to consular posts around the world.

In her litigation practice, Monica has proven, tested experience in successfully running novel points of law and obtaining ground-breaking decisions. She has used her strong academic foundation in all core areas of Public International Law and her previous practical experience working in large, complex cases before international tribunals (ICTY and ICJ), to successfully represent human rights claims. She has particular experience in dealing with the interface of different areas of public international law (such as immunities/human rights; international human rights law/international humanitarian law; human rights/international refugee law; human rights /ius ad bellum/ius in bellum, environmental law/human rights) in human rights litigation.

As a world expert in the Inter-American system, Monica has particular interest in duty to investigate cases (e.g. such as in the context of inquests and enquiries), before English courts, including cases raising extra-territorial issues, concerning massacres or violations taking place abroad. The Inter-American system has produced most of the jurisprudence on the duty to investigate often relied on by the European Court of Human Rights and the UK Supreme Court in deciding cases raising Article 2 of the European Convention. Monica is interested both in extra-territorial cases raising temporal issues under the right to investigate, as well as territorial issues, namely the scope of extraterritorial jurisdiction and the duty to investigate.

Monica also welcomes instructions raising complex jurisdictional public international law matters (such as those raised by extraordinary rendition cases), acts of state doctrine, non-justiciability, and universal jurisdiction.

Monica has also a keen interest in the interface of human rights and environmental law. She acted as counsel in the first world case on climate change  (before the UN Human Rights Committee) securing a landmark on climate change justice. She is recognised as a leading barrister in the Legal 500 noting that “She astutely combines vast knowledge of human rights and international environmental law with great advocacy skills.” In 2007 she was awarded the Justice Gruber Prize for her international litigation and in 2006, the Inge Genekfe award for her ground-breaking work on torture.
