  • Arbitration M

    Hilary Heilbron’s primary focus is now sitting as an international arbitrator in a variety of jurisdictions.

    She has accepted in excess of 125 appointments as party nominated arbitrator, institution appointed and sole arbitrator as well as an emergency arbitrator. She has also chaired many tribunals of leading international arbitrators. Her appointments have been under ICC, LCIA, SCC, SIAC, HKIAC and ICDR as well as ad hoc appointments. Many of these relate to substantial claims including in excess of US$1 billion. She also has experience of arbitrations in many foreign laws: both civil and common law and many industrial sectors in a variety of types of claim including, but not limited to, energy, solar power, telecommunications and media, joint ventures and share sale agreements. 

    She has recently been a member of several international arbitration task forces, namely the ICCA-ASIL Task Force on Damages; the ICCA/IBA Joint Task Force on Data Protection in International Arbitration Proceedings; and remains a member of the ICDR Working Group on Arbitration of Technology and Life Sciences Disputes. She is a former member of the LCIA Court and of the ICC UK Arbitration and ADR Committee.

    She speaks regularly to international audiences and writes on the subject. Past prestigious lectures include the keynote lecture at Fordham University School of Law, New York, the annual Clayton Utz lecture in Sydney, Australia, and the Annual Unidroit/University of Roma lecture.

    She is the author of a book on international arbitration in London.

    She has been described recently as having a “stellar reputation” and being an “amazing arbitrator”.

    The range of claims in which she sits as arbitrator is wide and includes:

    • share purchase and subscription agreements
    • joint ventures;
    • power, water and energy issues including pricing issues and oil exploration;
    • distributorship agreements;
    • telecommunications issues;
    • pharmaceutical issues;
    • banking issues;
    • solar;
    • hotel management;
    • guarantees;
    • securities issues;
    • international sale of goods cases;
    • cargo issues;
    • geophysical services; and
    • a host of various other contractual issues.

    Notable cases relating to arbitration  where she has appeared as counsel include: Dallah Real Estate Tourism Holding Co v Government of Pakistan [2010] UKSC 46; La Societe pour la Recherche, la Production, le Transport, la Transformation et la Commercialisation des Hydrocarbures SpA (Sonatrach) v Statoil Natural Gas LLC (Statoil) [2014] EWHC 875 (Comm), SulAmerica Cia Nacional de Seguros & 5 others v (1) Enesa Engenharia S.A - Enesa (2) Energia Sustentavel do Brasil - ESBR (3) Construcoes e Comerica Camargo Correa [2012] EWHC 42 (Comm).

  • Commercial M

    Before focusing more on international arbitration as arbitrator and counsel in arbitrations and arbitral related court work, Hilary Heilbron established an excellent reputation as counsel principally in commercial litigation and the English courts including the Supreme Court, House of Lords and Privy Council.

    She has acquired very considerable knowledge of international conflicts, jurisdictional and similar issues, about which she has spoken and written on many occasions and experience of a vast range of industry and financial sectors. She has acted for international conglomerates, utility companies, key financial regulators, FTSE 100 companies, governments as well as many foreign and national public and private companies. She has appeared as counsel in professional disciplinary hearings and appeals. She also has the relatively rare experience of having been a Department of Trade and Industry Inspector in a DTI inquiry into a major public company. She has advised and represented international celebrities and other well-known people in defamation cases.

    Her skill as an advocate remains and she has been described recently as being recognised for her “excellent counsel work in international arbitration”.
