Koon Wing Yee v Insider Dealing Tribunal

Where proceedings, though labelled civil, are in substance criminal because they expose a person to a punitive sanction for seriously dishonest conduct, the criminal-charge protections of Article 11 of the Hong Kong Bill of Rights apply, including the presumption of innocence and proof beyond reasonable doubt; the Insider Dealing Tribunal's punitive fining power, applied on a civil standard, was therefore unconstitutional.
