Cases considering section 117 38

Matthew Carter v The Chief Constable of Essex Police

[2025] EWCA Civ 367 · 9 April 2025

Section 117 permits reasonable force, if necessary, where PACE confers a power on a constable without requiring another person’s consent. The court held that the lawful clothing-removal power could be exercised with necessary and reasonable force in the circumstances. (see paras [35]; [71]; [77])

McDonnell v The Commissioner of Police for the Metropolis & Anor

[2015] EWCA Civ 573 · 14 May 2015

The court applied the requirement of reasonable force to the officer’s take-down of the claimant. The act was reasonable when assessed against the urgent circumstances and perceived risks; the unintended severity of the injury did not establish the contrary (see paras [24]–[29]).

McDonnell v The Commissioner of Police for the Metropolis & Anor

[2015] EWCA Civ 565 · 14 May 2015

Applies the reasonable-force standard to the exercise of a police power. The Court of Appeal concluded that the force used in the arrest was reasonable when assessed against the circumstances known to the officer, including the need for swift action and the risk of escape or weapons. (see paras [24]–[29])
