²³ In Waters v Commissioner of Police of the Metropolis [2000] 1 W.L.R. 1607, for example, Lord Jauncey held that “In Hill v Chief Constable of West Yorkshire [1989] the House of Lords held that public policy precluded an action for damages in negligence against the police arising out of the manner in which they investigated crime, in that case the activities of a serial killer. I see no reason why this principle should not apply equally [here]”. Similarly, Lord Wright, writing extra-judicially about Egerton v Brownlow (1853) 4 H.L.C. 1, 151; 10 E.R. 359, 419, referred to “the principle of public policy” in R.

⁷⁷ Stapleton, “Duty of Care Factors”, p. 59.

⁷⁸ Despite, as we have seen, not adopting the terms “principle” and “policy”, Stapleton identifies 50 “factors” (29 “convincing” and 21 “unconvincing”) that courts have used in denying or imposing a duty of care, many of which are unequivocally concerned with what advocates of the distinction would describe as policy, such as the “socio-economic impact” that the recognition of a duty would have on the “budgets and/or activities of public bodies to the detriment of a specified public interest”: ibid., at p. 93. Importantly, Stapleton makes explicit that her task is descriptive and not normative: ibid., at p. 89.
