Establishing the Necessity of Arrest: Insights from The Commissioner of Police for the Metropolis v. MR ([2019] EWHC 888 (QB))

Introduction

In the case of The Commissioner of Police for the Metropolis v. MR ([2019] EWHC 888 (QB)), the England and Wales High Court addressed significant issues pertaining to the lawfulness of police arrests under the Police and Criminal Evidence Act 1984 (PACE). The appellant, the Commissioner of Police, contested a lower court's decision that upheld MR's claims of false imprisonment and assault, stemming from what was deemed an unlawful arrest for harassment. This commentary explores the intricacies of the case, the court's reasoning, and the implications for future law enforcement practices.

Summary of the Judgment

The High Court dismissed both the appeal by the Commissioner of Police and the cross-appeal by MR. The judge concluded that while the arresting officer, DS Murphy, had an objectively reasonable suspicion that MR had committed harassment, there was no objective necessity to arrest MR, rendering the arrest unlawful. Consequently, MR's claims for false imprisonment and assault were upheld, and the damages awarded by the lower court were affirmed.

Analysis

Precedents Cited

The judgment extensively referenced established case law to frame the standards for lawful arrest:

  • Hayes v Chief Constable ([2012] 1 WLR 517): Established a two-stage test for assessing the necessity of an arrest under PACE, focusing on the officer's honest belief and objective reasonableness.
  • Castorina v Chief Constable of Surrey (1988) 160 LR Rev 241: Outlined the criteria for reasonable suspicion under section 24(2) PACE.
  • Parker v Chief Constable of Essex Police [2018] EWCA Civ 2788: Approved an embellishment of previous tests to incorporate necessity.
  • Alford v Chief Constable of Cambridgeshire [2009] EWCA Civ 100: Emphasized appellate courts' roles in independently reviewing reasonable grounds for suspicion.
  • Hussein v Chong Fook Kam (1970) AC 942: Discussed the low threshold for suspicion.
  • Holtham & Holtham v Commissioner of the Police of the Metropolis [1987]: Highlighted that applying stricter tests could constitute a fundamental error.
  • Associated Provincial Picture Houses Ltd v Wednesbury Corporation (1948) 1 KB 223: Introduced the Wednesbury reasonableness principle, later integrated into the necessity assessment.
  • R (B) v Chief Constable of NI [2015] EWHC 3691 (Admin) and R (L) [2017] EWHC 129 (Admin): Clarified the application of the Wednesbury test within PACE.

Impact

This judgment reinforces the stringent requirements for law enforcement when exercising arrest powers. It underscores that while reasonable suspicion is a low threshold, the necessity of arrest demands a high level of justification, especially in cases involving low-level offenses like harassment. Future cases will likely reference this decision to balance police authority with individual liberties, emphasizing the courts' role in safeguarding against arbitrary arrests.

Additionally, the case clarifies the interplay between subjective beliefs of law enforcement officers and the objective standards the judiciary applies. This balance ensures that while officers have the discretion to act, their decisions remain accountable under legal scrutiny.

Complex Concepts Simplified

Reasonable Grounds for Suspicion

This refers to the lawful basis a police officer must have to believe that an individual has committed an offense. It's a low threshold, meaning the officer doesn't need concrete evidence, just a reasonable basis for their belief.

Necessity of Arrest

Beyond suspecting someone of wrongdoing, the officer must also determine if arresting the individual is essential for furthering the investigation or preventing potential issues. This prevents unnecessary deprivation of an individual's liberty.

Wednesbury Reasonableness

Originating from administrative law, this principle assesses whether a decision made by a public authority is so unreasonable that no reasonable authority would ever consider it. In policing, it ensures that arrest decisions aren't arbitrary.

CRIS Report

The Crime Reporting Information System (CRIS) is a database used by law enforcement in the UK to record details of crimes and suspects. It aids officers in making informed decisions during investigations and arrests.

Conclusion

The Commissioner of Police for the Metropolis v. MR serves as a pivotal reference in understanding the delicate balance between police authority and individual rights within the UK's legal framework. The High Court's affirmation that MR's arrest was unlawful, despite the officer's reasonable suspicion, highlights the judiciary's unwavering commitment to ensuring that arrest powers are exercised judiciously and only when absolutely necessary. This decision not only reinforces the protective measures afforded to individuals under PACE but also guides law enforcement agencies in refining their operational protocols to align with legal standards, thereby fostering a more accountable and fair policing system.
