He is frequently instructed as sole counsel or as part of a larger counsel team in international arbitrations (under all major institutional rules) and in disputes before the English courts.

Mark’s cases frequently involve applications for interim relief from courts and arbitral tribunals. He has experience obtaining freezing injunctions, relief from emergency arbitrators, anti-suit injunctions and stays of domestic court proceedings on the basis of jurisdiction and arbitration agreements. Mark has also represented clients in proceedings to enforce arbitral awards under the New York Convention.

Before joining the English Bar in 2016, he practised as a barrister in New Zealand at a leading commercial set. Mark also worked as a law clerk for two leading international arbitrators, where he gained exposure to many commercial and investment treaty arbitrations. He is currently writing a textbook, with co-authors, on the arbitration of joint venture disputes.

Mark holds degrees in both Law and Accounting from the University of Auckland, where he wrote his dissertation thesis on damages in international investment arbitration. Mark also holds a Bachelor of Civil Law degree from the University of Oxford where he obtained a Distinction and the prize for the highest examination mark in the International Law of the Sea course.
