Knightley v. Johns & Ors

Factual and Procedural Background

On a Friday evening in October 1974, Police Constable Plaintiff rode his motor bicycle the wrong way along a tunnel in The City and collided with Defendant's oncoming motor car. Plaintiff sued Defendant for negligence causing serious injuries, as well as Police Inspector Defendant and the Chief Constable of The West Midlands for the inspector's alleged negligence in instructing or permitting Plaintiff to ride the wrong way. The primary alleged cause was Defendant Johns’ negligence in overturning his motor car in the tunnel, which led to the subsequent events. The trial judge acquitted all defendants except Defendant Johns, whose negligence was conceded. The dispute at trial concerned causation and contributory negligence, leading to Defendant Johns’ appeal and Plaintiff’s cross-notice. The Chief Constable and Inspector joined Defendant Johns in alleging contributory negligence by Plaintiff.

The incident occurred in the Queensway tunnel, which has two northbound and two southbound lanes, with the southbound tunnel closed for maintenance. Defendant Johns overturned his car in the northbound tunnel, blocking lane 2, with injured passengers partially blocking lane 1. Following the accident, a series of police communications and actions occurred, including Plaintiff receiving instructions from Inspector Defendant to close the tunnel. Plaintiff proceeded to ride the wrong way back through the tunnel, against traffic, leading to a collision with Defendant Cotton’s car near the tunnel entrance.

The trial judge found Plaintiff was not negligent in obeying the inspector's order to ride the wrong way, though he increased the risk by riding on the opposite side to another officer. The inspector did not testify, and his report was admitted late. The inspector claimed he had forgotten to close the tunnel, and that the officers decided themselves to ride against traffic. The police actions were found to be in breach of Standing Orders governing tunnel accidents, which required specific procedures for closing the tunnel and escorting emergency vehicles.

Legal Issues Presented

1. Whether Defendant Johns’ negligence was the operative cause of Plaintiff's injuries or whether the negligence of Inspector Defendant and Plaintiff themselves caused or contributed to the accident.
2. Whether the Inspector’s failure to close the tunnel and the subsequent police actions constituted a new cause breaking the chain of causation from Defendant Johns’ negligence.
3. Whether Plaintiff was contributorily negligent in riding the wrong way through the tunnel on the Inspector’s orders.
4. Whether the police breaches of Standing Orders were foreseeable consequences of Defendant Johns’ negligence.

Arguments of the Parties

Appellant's Arguments (Defendant Johns)

• The police actions, including breaches of Standing Orders and failure to close the tunnel, were a series of unforeseeable and intervening negligent acts breaking the chain of causation from Defendant Johns’ original negligence.
• The police’s ineptitude was improbable and unforeseeable, thus relieving Defendant Johns of liability for Plaintiff’s injuries.

Respondent's Arguments (Plaintiff and Police Inspector/Chief Constable)

• Plaintiff was not negligent in riding the wrong way as he was acting under the Inspector’s orders and in an emergency situation.
• The Inspector was negligent in failing to close the tunnel and ordering Plaintiff and another officer to ride the wrong way, contrary to Standing Orders.
• The negligence of the Inspector and the police officers was a concurrent cause of Plaintiff’s injuries and did not break the chain of causation from Defendant Johns’ negligence.
• The breaches of Standing Orders were foreseeable consequences of the original accident and did not relieve Defendant Johns of liability.

Court's Reasoning and Analysis

The court first evaluated the police actions, particularly the Inspector’s failure to close the tunnel and the instruction to Plaintiff to ride the wrong way. The Inspector’s negligence was established due to breach of Standing Orders designed to ensure safety in tunnel emergencies. The Plaintiff was found not negligent in obeying the Inspector’s order and in his choice of lane on the spur of the moment, despite increasing risk.

The court then examined whether the Inspector’s negligence and the police actions were concurrent causes with Defendant Johns’ negligence or new causes breaking the chain of causation. The judge originally held Defendant Johns’ negligence as the operative cause, reasoning that the police actions were foreseeable and natural consequences of the emergency created.

However, on appeal, the court disagreed with this conclusion. It found that the Inspector’s negligence was a new and independent cause that disturbed the sequence of events and broke the causal chain from Defendant Johns’ original negligence. The breakdown in police communication, breaches of Standing Orders, and dangerous instructions given to police officers created an extraordinary sequence of events too remote from Defendant Johns’ initial wrongdoing to hold him liable for Plaintiff’s injuries.

The court applied established legal principles on causation and novus actus interveniens, emphasizing that liability depends on reasonable foreseeability and whether intervening acts are natural and probable consequences of the original negligence. Rescue cases were extensively reviewed, confirming that rescuers’ reasonable conduct does not break the chain of causation, but wanton or reckless conduct might. The court concluded that the police negligence was a sufficiently independent cause to relieve Defendant Johns from liability for Plaintiff’s injuries.

Holding and Implications

The court ALLOWED THE APPEAL, setting aside the judgment against Defendant Johns and the judgment for the Inspector and Chief Constable against Plaintiff. The court entered judgment for Plaintiff against the Inspector and Chief Constable for damages to be assessed.

The decision means that the Inspector’s negligence in failing to close the tunnel and ordering dangerous police conduct was the legal cause of Plaintiff’s injuries, breaking the causal chain from Defendant Johns’ initial negligence. Plaintiff was not contributorily negligent for obeying the Inspector’s orders. No new precedent was established beyond the application of well-known principles of causation, novus actus interveniens, and rescue doctrine in negligence law.
