"Justice" is the third episode of science fiction sitcom Red Dwarf Series IV and the twenty-first episode in the series run. It was first broadcast on the British television channel BBC2 on 28 February 1991; although it was planned to be broadcast as the second episode, it was moved back in the schedule by the BBC. Written by Rob Grant and Doug Naylor, and directed by Ed Bye, the episode features the crew's visit to a high-tech prison where Rimmer is charged with the death of the Red Dwarf crew.
