Following the common law system introduced into Hong Kong when it became a Crown colony, Hong Kong's criminal procedural law and the underlying principles are very similar to the one in the UK. Like other common law jurisdictions, Hong Kong follows the principle of presumption of innocence. This principle penetrates the whole system of Hong Kong's criminal procedure and criminal law. Viscount Sankey once described this principle as a 'golden thread'. Therefore, knowing this principle is vital for understanding the criminal procedures practised in Hong Kong.
