so he sought indemnification from the negligent driver and his insurers for the amounts he had been ordered to pay. This was not a claim for his own personal injuries nor direct financial loss, but indirect loss. The three women could not have sued the driver directly because they were not foreseeable and so no duty of care was owed to them. The question was whether a person convicted of a crime was entitled to be indemnified against the consequences of that crime. Woolf J. held that the action would be dismissed on two grounds. First, the damages were too remote to be recoverable and, if such actions were to be allowed, it would leave insurers open to indefinite liability for an indefinite duration. Secondly, as a matter of policy, defendants should not have a right to be indemnified against the consequences of their crimes. In Clunis v Camden and Islington Health Authority (1998) QB 978 the claimant had been discharged from hospital where he had been detained under s3 Mental Health Act 1983. He was to receive aftercare services in the community under s117 Act 1983, but his mental condition deteriorated and, two months later, he fatally stabbed a stranger at a London Underground station. He pleaded guilty to manslaughter on the ground of diminished responsibility and was ordered to be detained in a secure hospital. Subsequently, he brought an action against his local health authority for negligence. The health authority applied to strike out the claim as disclosing no cause of action on two grounds. First, that the claim arose out of the health authority's statutory obligations under s117 Act 1983 and those obligations did not give rise to a common law duty of care. Secondly, that the claim was based on the plaintiff's own criminal act. In the Court of Appeal, the health authority's appeal was allowed on both grounds. The factual test of causation The basic test for establishing causation is the "but-for" test in which the defendant will be liable only if the claimant’s damage would not have occurred "but for" his negligence. Alternatively, the defendant will not be liable if the damage would, or could on the balance of probabilities, have occurred anyway, regardless of his or her negligence. To understand this, a distinction has to be made between cause and a precondition for the events. Lord Hoffmann in South Australia Asset Management Corp
