Union, Defendant, had a rule that a person could not be a member if he had ever been convicted of a criminal offence.
Plaintiff had been convicted of an offence in Jersey, which was discovered after years of membership and service on the executive.
CA held that the union was therefore entitled to expel Plaintiff / assert that he had never been a member.
The condition was to be construed as referring to all criminal offences, regardless of which jurisdiction / legal system they were committed under.
