The claimant suffered psychiatric injury in a rail crash caused by the defendant’s negligence. Under this condition of Post-Traumatic Stress Disorder, the claimant had later gone on to kill another person, and he had been detained under section 41. He now sought damages for his loss of earnings through detention in prison and mental hospital.
Held: Such damages could not be claimed successfully once the claimant had been convicted. Though the defendants had admitted their negligence, success for the claimant would be against the public policy maxim that ex turpi causa non oritur actio. If the case was extreme, and the order for detention was made purely for the defendant’s mental condition, and not for the criminal behaviour, the maxim might not apply, but that was not the case here.
Lord Hoffmann said: ‘there is no dispute that there was a causal connection between the tort and the killing. The evidence which the judge accepted was but for the tort, Mr Gray would not have killed. But the rule of public policy invoked in this case is not based upon some primitive psychology which deems mental stress to be incapable of having a connection with subsequent criminal acts . . the case against compensating Mr Gray for his loss of liberty is based upon the inconsistency of requiring someone to be compensated for a sentence imposed because of his own personal responsibility for a criminal act.’ and ‘the maxim ex turpi causa expresses not so much a principle as a policy. Furthermore, that policy is not based upon a single justification but on a group of reasons, which vary in different situations.’
Lord Brown said: ‘The law cannot at one and the same time incarcerate someone for his criminality and compensate him civilly for the financial consequences.’
