Chief Constable of West Yorkshire Police v Khan [2001] UKHL 48 is a UK labour law case concerning the test for victimisation and the legitimate steps an employer can take after dismissed a person who is bringing a discrimination claim against them.

Sergeant Raham Noor Khan was not hired for another job, after he had left the first with a race discrimination claim pending.

[1] The House of Lords overturned the victimisation claim, holding the police had a legitimate interest in withholding the reference from Mr Khan.

Employers, acting honestly and reasonably, ought to be able to take steps to preserve their position in pending discrimination proceedings without laying themselves open to a charge of victimisation.

The existence of that adversarial relationship may reasonably cause the employer to behave in a way which treats the employee less favourably than someone who had not commenced such proceedings.’[2]
