Tindall & Anor v Chief Constable of Thames Valley Police
United Kingdom Supreme Court – Anonymised Case Summary
Factual and Procedural Background
During the early hours of 4 March 2014, Witness A lost control of his vehicle on an icy section of the Road and called the police. Three police officers attended, briefly placed a single warning sign and asked a control centre to request a gritting vehicle, but they left the scene at about 05:26 taking the sign with them. Between 05:45 and 05:52, a second collision occurred on the same ice patch: a vehicle driven northbound skidded, crossed the carriageway and struck a car driven southbound by the Deceased. Both drivers died.
Plaintiff, the Deceased’s widow and administratrix, sued the Chief Constable of The Police Force (with the highway authority also named but not party to this appeal). She alleged that the police response displaced Witness A’s own attempts to warn motorists and thereby made matters worse, or alternatively that one of the recognised exceptions to the general rule against liability for omissions applied.
The Defendant applied to strike out the claim or obtain summary judgment. The High Court refused to do so, but the Court of Appeal reversed that decision. Plaintiff appealed to the Supreme Court.
Legal Issues Presented
- Whether, on the assumed facts, the police owed the Deceased a common-law duty of care in negligence because their attendance made matters worse by displacing another source of protection (the “interference principle”).
- Whether any recognised exception to the general rule against liability for omissions (assumption of responsibility, control of a danger, or special status) imposed a duty of care on the police.
- Whether the claim should be struck out or disposed of summarily for having no real prospect of success.
Arguments of the Parties
Plaintiff's Arguments
- The police attendance stopped Witness A from continuing to warn other motorists, increasing the risk to road users; this “interference” constituted making matters worse.
- By arriving with blue lights and signage and then withdrawing all safeguards, the police assumed control of the scene and therefore a duty to protect subsequent motorists.
- Even if no positive act was directed at Witness A, the foreseeable effect of police presence was to displace his rescue efforts; foreseeability, not coercion, is decisive.
- Alternatively, the police fell within established exceptions (assumption of responsibility, control, or status-based obligation) recognised in case law such as Dorset Yacht and Kent v Griffiths.
Defendant's Arguments
- Police merely failed to confer a benefit; they did not create or exacerbate the danger and therefore owed no duty under the principles affirmed in Michael and Robinson.
- There was no assumption of responsibility: the police made no representation to the Deceased or other motorists and none relied on them.
- The officers neither knew nor could reasonably have known of Witness A’s private intention to continue warning traffic; foreseeability was absent.
- Control of the accident scene is not the same as control of the ice hazard 184 metres away; no special control over the source of danger was exercised.
- Given settled authority, the claim disclosed no reasonable cause and should be struck out or dismissed summarily.
Table of Precedents Cited
| Precedent | Rule or Principle Cited For | Application by the Court |
|---|---|---|
| East Suffolk Rivers Catchment Board v Kent [1941] AC 74 | Liability arises only where the defendant’s acts make matters worse; mere failure to confer a benefit is not actionable. | Used to illustrate the baseline comparison when assessing whether police made matters worse. |
| Ancell v McDermott [1993] 4 All ER 355 | No duty on police to warn of road hazards they did not create. | Cited as factually similar authority supporting absence of duty. |
| Capital & Counties v Hampshire CC [1997] QB 1004 | Fire brigade liable only where it positively exacerbates danger (e.g., turning off sprinklers). | Analogy drawn to distinguish between making matters worse and ineffectual rescue. |
| Gorringe v Calderdale MBC [2004] UKHL 15 | Public bodies are not generally liable for failing to confer benefits. | Reinforced no-liability principle for omissions. |
| Michael v Chief Constable of South Wales Police [2015] UKSC 2 | General rule against liability for omissions; two limited exceptions (control & assumption of responsibility). | Supreme Court treated it as settling modern law; no exception applied here. |
| Robinson v Chief Constable of West Yorkshire [2018] UKSC 4 | Liability where police affirmatively cause foreseeable physical harm. | Distinguished: present case concerned an omission, not a positive act. |
| Dorset Yacht Co v Home Office [1970] AC 1004 | Duty may arise where defendant has control over third parties who cause damage. | Held inapplicable; police had no comparable control over the ice hazard. |
| Stovin v Wise [1996] AC 923 | Classic illustration distinguishing omissions from negligent acts. | Used conceptually to frame baseline comparison. |
| Kent v Griffiths [2001] QB 36 | Assumption of responsibility and “interference” through misleading assurances. | Discussed as doctrinal support for the interference principle. |
| Darnley v Croydon Health Services NHS Trust [2018] UKSC 50 | Providing misleading information that foreseeably causes harm is an actionable positive act. | Endorsed the interference principle articulated in Kent. |
| OLL Ltd v Secretary of State for Transport [1997] 3 All ER 897 | Coastguard owed no duty for negligent rescue coordination. | Court disagreed with its reasoning; treated as wrongly decided. |
| Carmarthenshire CC v Lewis [1955] AC 549 | Duty arising from control over a dangerous third party (a child). | Example of control exception; factually different from present case. |
| Goldman v Hargrave [1967] 1 AC 645 | Occupier’s duty to prevent natural hazard on land from harming neighbours. | Not extended to public roads; distinguished. |
| N v Poole BC [2019] UKSC 25; HXA v Surrey CC [2023] UKSC 52; Great Lakes v RAV Bahamas [2024] UKPC 11 | Approved four-fold classification of exceptions (Tofaris & Steel). | Cited as analytical framework but none of the exceptions applied. |

Court's Reasoning and Analysis
The Court reaffirmed the fundamental distinction between (a) positive acts that make matters worse and (b) omissions or ineffectual attempts to confer a benefit. It recognised the interference principle – liability may arise where the defendant prevents another rescuer from acting – as a legitimate subset of “making matters worse.” However, to invoke that principle the claimant must establish that the defendant knew or ought to have known its conduct would displace the rescuer.
Applying that test, the Court found a “fatal factual lacuna”: nothing in the pleadings or evidence suggested the police were, or should have been, aware that Witness A intended to continue warning motorists. Without foreseeability of displacement, the interference principle could not generate a duty.
The Court then examined each proposed exception to the no-omissions rule:
- Assumption of responsibility: impossible; the police made no representation to road users and none relied on them.
- Control of the danger: the officers never assumed control of the ice patch, only of the immediate crash site.
- Status-based duty: any broad duty founded on police status was rejected in Michael; the Court declined to revisit that authority.
Because the claim lacked an essential factual foundation and the governing law is settled, allowing it to proceed would waste judicial resources. Summary judgment and strike-out were therefore appropriate.
Holding and Implications
APPEAL DISMISSED. The Supreme Court upheld the Court of Appeal’s order striking out the negligence claim against the Defendant.
Implications: The judgment clarifies that the interference principle can ground liability only where the defendant reasonably foresees that its conduct will displace another rescuer. It reinforces the settled distinction between harmful positive acts and non-action, confirming that emergency services are not liable for mere ineffectual responses unless they demonstrably aggravate the danger with foresight of risk. No new precedent is set, but the decision strengthens the predictive value of Michael and Robinson for future omission-based claims against public authorities.
