PACE 1984 s.24(5) Necessity Test Deficits

Voluntary Attendance Feasible Suspect was cooperative, identifiable, and willing to attend under caution without formal arrest.

Zero Flight or Interference Risk No risk of disappearing, destroying evidence, or obstructing prompt and effective investigation.

Lack of Objective Grounds for Suspicion Arresting officer had no objectively verifiable reasonable grounds under s.24(2) PACE.

Misfeasance in Public Office Indicators

Requires proving the exercise of public power with bad faith or targeted malice.

Limb 1: Targeted Malice Act done specifically with the intent to injure the claimant.

Limb 2: Reckless Indifference Officer knowingly exceeded powers or acted with reckless disregard for legality and resulting injury.

Ulterior / PR Motive Identified Arrest staged for media spectacle or reputational pressure rather than genuine investigative necessity.

Aggravating & Exemplary Elements

High-Profile Media Leak / Reputational Harm Press tip-offs, broadcast perp-walk, or severe public humiliation.

Oppressive or Arbitrary Conduct Unconstitutional or oppressive government behaviour (Rookes v Barnard test for exemplary damages).

Overall Claim Viability High (78%) Actionable on multiple torts

False Imprisonment Strong PACE Code G breach

Misfeasance Likelihood Probable Limb 2 threshold met

Estimated Quantum Range £18k – £45k Includes aggravated heads

Primary Civil Torts 3 Valid Causes

1. False Imprisonment & Unlawful Arrest High Merit

Breach of PACE 1984 s.24(5) necessity criteria. Arresting when voluntary caution interview was practical vitiates statutory power, rendering entire custody period actionable.

2. Misfeasance in Public Office Probable

Established under Three Rivers DC Limb 2: bad faith or reckless indifference to lawfulness where police knowingly bypass PACE safeguards for improper purpose.

3. Human Rights Act 1998 (ECHR Art. 5 & 8) Established

Unjustified deprivation of liberty (Article 5) and disproportionate infringement on private/professional reputation (Article 8) without lawful justification.

Hayes v Chief Constable of Merseyside Police [2011] EWCA Civ 911

Court of Appeal established that police necessity test under PACE s.24(5) requires subjective belief held on objective reasonable grounds, considering non-arrest alternatives.

Thompson & Hsu v Commissioner of Police of the Metropolis [1998] QB 498

Standard judicial guidance on quantum in actions against the police: progressive tariffs for hours of unlawful detention, aggravated damages, and exemplary compensation caps.

Rookes v Barnard [1964] AC 1129

Sets common law limits on exemplary damages; Category 1 applies directly to oppressive, arbitrary, or unconstitutional action by servants of government and constabularies.

About this Assessment Tool & English Law Limitations

This tool models civil liability against police forces under the laws of England and Wales. It incorporates statutory criteria from the Police and Criminal Evidence Act 1984 (PACE), particularly Section 24 as amended by the Serious Organised Crime and Police Act 2005 and Code of Practice G. The tort of misfeasance in public office requires the claimant to satisfy a rigorous threshold of bad faith or reckless disregard of power (Lord Steyn in Three Rivers). Calculation of damages follows the Court of Appeal guideline brackets in Thompson & Hsu adjusted for modern indexation. This model serves analytical and comparative purposes for legal observers and claimants assessing police accountability claims.
