Angeline has a broad ranging practice. While primarily known for her international arbitration practice (as counsel and arbitrator), she also has substantial experience in handling commercial disputes and cases involving issues of public law, constitutional law, human rights law and increasingly European Union law.

Angeline is widely regarded as one of the leading practitioners in her generation of arbitration lawyers. In 2018, Angeline was listed as the fifth most highly regarded arbitration practitioner at the UK bar by Who’s Who Legal UK Bar’s guide. In 2017, she was named as a ‘Star at the Bar’ by Legal Week, recognised for her “excellent judgement and leadership qualities” and not being frightened to tackle novel and difficult areas of law, or “to deal head-on with the more complicated aspects of a case”.

Prior to joining Matrix, Angeline was Counsel and Solicitor Advocate in the International Arbitration Group at Allen and Overy LLP, spending time in the London and Hong Kong offices and on secondment to the LCIA. She has worked with counsel in a wide range of jurisdictions including India, Myanmar, Indonesia, Belize, Hong Kong, Turks & Caicos Islands, Singapore, United States, Kazakhstan, Rwanda and various European states.

Angeline has five core areas to her practice:

Commercial litigation and arbitration: Angeline has acted as counsel in a range of complex arbitrations under a range of arbitral rules and has been instructed (unled) in commercial court cases. Her practice includes commercial arbitration across a range of sectors (including construction, energy, financial and telecoms disputes). She has particular expertise in emerging market jurisdictions and in handling commercial disputes against states.

Investment treaty arbitration: Angeline has acted as counsel in investment treaty claims and regularly advises on the structuring of investments in order to gain investment treaty protection. She led the team advising on three investment treaty claims against the Government of Belize arising out of the nationalisation of Belize Telemedia Limited which successfully settled.

Public law and constitutional claims: Angeline advises on a wide range of public law issues. She has acted on judicial review and constitutional challenges before the English courts as well as courts elsewhere in the Commonwealth, including the UK Supreme Court, the Privy Council and the Caribbean Court of Justice.

Court applications related to arbitration: Angeline has particular expertise in this area. She has advised on a range of court applications related to arbitration, including anti-suit injunctions, interim relief in support of arbitration and enforcement of arbitral awards. She acted on two of the leading arbitration cases in recent years; AES Ust- Kamenogorsk v UST-Kamenogorsk JSC [2013] UKSC 35 (a leading case on anti-suit injunctions in support of an arbitration) and Jivraj v Hashwani [2011] UKSC 40 (concerning whether an arbitration agreement which specified that arbitrators must be of a particular religious faith was contrary to discrimination legislation and therefore unlawful, a case which had broader implications for the validity of arbitration clauses which commonly include nationality requirements).

Arbitrator: Angeline sits as an arbitrator, having been appointed as sole arbitrator in LCIA, ICC, BVI IAC and ad hoc arbitrations and as presiding arbitrator in an LCIA case. She is appointed to the HKIAC list of arbitrators and the BVI IAC panel of arbitrators.

Angeline is regulated by the Bar Standards Board and accepts instructions under Standard Contractual Terms, details of which can be found here.
