Hail the Judge (1994)

Pao Lung-Sing (Stephen Chow), a decendant of the famous Judge Pao Ching Tient, is a 9th degree corrupt judge (lowest degree) who changes his tune when he tries to champion a woman Chi Siu-Lin (Cheung Man), who was framed for killing her husband. As a result, Pao is forced to flee and through a series of events (often hilarious) becomes a 1st degree judge and comes back to wreak havoc and justice on the guilty.
