In British law, perversion of the course of justice is a criminal offence in which someone acts in a manner that in some way prevents justice being served on themselves or other parties. Perverting the course of justice is an offence at common law. It carries a theoretical maximum sentence of life imprisonment, although no sentence of more than 10 years has been handed down in the past one hundred years.
Perversion of the course of justice takes the form of one of three acts:
- Fabrication or disposal of evidence
- Intimidating a witness or juror
- Threatening a witness or juror
Similar crimes include perjury and contempt of court.
