1. The Shire was small in numbers. By inference, its resources were small and its personnel few. What might be expected of a large public authority, well resourced and expertly advised, could not reasonably be imposed upon a body such as the Shire. On the other hand, the small size and population of the Shire made it easier for officers to visit and inspect sources of serious danger. It seems hardly likely that the discovery of a fire risk with a potential to threaten the main town of the Shire would be an everyday occurrence.

The small resources of the Shire make it reasonable that owners and occupiers of premises within the Shire should be expected to take precautions to protect themselves against risks rather than looking to the "deep pocket" of the public purse to do so. In this case that pocket would not be very deep at all. Owners and occupiers of property commonly do, and should, protect themselves, including by fire insurance[350]. The law should encourage self-reliance because it tends to promote greater economic efficiency[351]. To some extent, Shire rates and services would have been arranged with the operation of individual self-protection and private insurance in mind. These principles, whilst valid, cannot be extended to exclude recovery for every failure of the public authority to use its available powers[352]. That would not only contradict many decisions in negligence claims. It would be inconsistent with the established legal rule that in some circumstances, "may", in a statute empowering a public authority to act, can mean "must"[353].

A particular consideration of policy mentioned by Lord Hoffmann in Stovin is the undesirability of adopting a rule which would result in insurance companies, under to their rights of subrogation, recouping themselves from the purse of a public authority[354]. However, in the absence of evidence (assuming it to be admissible) it is pure speculation as to whether the claimants here were insured or whether the public authority was uninsured. Of more direct concern would be the extension of duties to public authorities which would make it more difficult for them to obtain insurance or result in the curtailment of services because they are effectively uninsurable. There was no evidence on any of these questions.

It has been suggested that the separation of powers lies at the heart of restraint of courts in substituting their judgments for those of the public authority[355]. Typically, a court does not have the "financial, economic, social or political factors or constraints" before it that are available to the officers of the public authority[356] in the deployment of its resources. Courts have drawn a distinction between "policy" decisions, which they will leave to the public authority itself, and "operational" decisions which they will have competence to evaluate[357]. Although the distinction is far from perfect, it has some validity. In the present case, more effective notice to the owner and occupier of 70 Neil Street concerning the hazard of fire and the provision of follow-up would certainly fall on the "operational" side of the line. But this conclusion leaves standing Lord Hoffmann's comment that courts should be wary of undue intervention in decisions having significant implications for the budgets of public authorities[358]:

They will spend less on education or social services. I think that it is important, before extending the duty of care owed by public authorities, to consider the cost to the community of the defensive measures which they are likely to take in order to avoid liability."
