The principal authority with regards to the ambulance service is Kent v Griffiths & Others [2000] 2 All ER 474. Here, the ambulance service was regarded as part of the health service and not a rescue service and so the policy arguments applicable to the police and fire brigade had no general application. The judgment of the court in Kent was that the acceptance of a 999 call by the ambulance service established a duty of care. The acceptance of the call established proximity between the parties. There might, however, be situations where a duty of care could be excluded where the service had properly exercised its discretion to deal with a more pressing emergency before attending to the claimant or where it had made a choice about the allocation of resources.
