He regularly acts in litigation and arbitration for financial institutions, multinationals, and listed companies.  He has particular expertise in complex corporate, contractual, professional negligence, insurance and employment matters.

Kieran has recently acted in one of Hong Kong’s largest professional negligence litigations, a major shareholders’ claim in respect of a listed company, an international arbitration arising from a failed investment in a Chinese company, and a multi-million dollar dispute involving corporate espionage.  He also assists parties and regulators on contentious regulatory investigations.  This includes acting as counsel for a Hong Kong regulator to investigate and prosecute cases of non-compliance.
