Ernest has a focused practice on civil, public law and regulatory matters. He has appeared in all levels of Courts in Hong Kong and in administrative tribunals including the Inland Revenue Board of Review and the Market Misconduct Tribunal. He has been recognised as one of the leading juniors by Legal500 in both areas of commercial disputes, and administrative and public law.

He has experience in advising and appearing in cases concerning commercial and company disputes, land disputes and in particular on asset recovery litigations as a result of fraud or others misconducts.

He also has particular experience advising and appearing, on both sides, in public law matters involving constitutional questions, human rights, town planning, environment, taxation, regulatory and disciplinary matters. He also advises on public international law matters.

Prior to joining the Bar, Ernest read social sciences and law at the University Hong Kong with emphasis on international relations and public international law. He received his Master of Laws (International Law) with Class I Honours from the University of Cambridge under the supervision of Prof. James Crawford S.C. on the strength of his study in international constitutional law. He also worked as an intern at the International Criminal Tribunal for the Former Yugoslavia in The Hague with HH Judge Liu and assisted in several landmark decisions during that period.
