Magistrates' courts in Hong Kong have criminal jurisdiction over a wide range of offenses, and in general these offenses must only constitute two years' imprisonment or a fine of HK$100,000; in certain circumstances, sentences of three years may be imposed.

[1] All judges and magistrates must have qualified as legal practitioners either in Hong Kong or in another common law jurisdiction and have had substantial professional experience.

Their sentencing power is limited to a maximum fine of HK$50,000 or as specified in their warrants of appointment.

A deputy magistrate or deputy special magistrate is assigned by the Chief Justice for such period and on such terms as the chief justice thinks fit.

This makes additional manpower available to the magistrates' courts while also giving eligible persons experience on the bench, before the magistrate commits to a full-time posting or returns to private practice.
