Isaac’s practice focuses on commercial and financial disputes, financial regulatory proceedings, banking disputes, trust and property disputes.  He is often instructed for cases with complex elements involving a multi-disciplinary angle.  

In addition to his advocacy work in the courts, Isaac regularly acts both for and against regulators in professional disciplinary and regulatory proceedings, including those in specialist tribunals such as the Market Misconduct Tribunal and the Competition Tribunal.  Isaac also advises regularly on matters in relation to inquiries by the Listing Division or proceedings before the Listing Committee and the Listing Review Committee of the Hong Kong Stock Exchange.

Besides his civil practice, Isaac is also experienced in white-collar criminal defence work, having been involved in the high-profile trials of the former Chief Secretary of Hong Kong for corruption and of the former chairman of the Hong Kong General Chambers of Commerce for conspiracy to defraud.

Prior to joining the Bar, Isaac obtained his LLB (Government & Laws) and PCLL from the University of Hong Kong, and his LLM from the London School of Economics.  He further obtained a Postgraduate Diploma in EU Competition Law from King’s College London.
