Jones v Birmingham City Council and another
[2023] UKSC 27
Self-defence has two limbs: the trigger (the individual's genuine belief) and the response (the reasonableness of the response).
Common law, codified in s 76 of the Criminal Justice and Immigration Act 2008 (criminal proceedings) and Ashley v Chief Constable of Sussex Police (civil proceedings)
In criminal proceedings, a genuinely held belief justifies self-defence regardless of whether it was mistaken or unreasonable.
s 76 Criminal Justice and Immigration Act 2008; R v Morgan; R v Williams (Gladstone); Beckford v The Queen; R v Keane
In civil proceedings, a mistaken belief justifies self-defence only if it was reasonable.
Ashley v Chief Constable of Sussex Police
Police officers can use reasonable force in exercising their powers (s 117 Police and Criminal Evidence Act 1984 and s 3 Criminal Law Act 1967).
s 117 Police and Criminal Evidence Act 1984; s 3 Criminal Law Act 1967
The standard for use of force in police disciplinary proceedings is 'necessary, proportionate and reasonable in all the circumstances' (Police (Conduct) Regulations 2012).
Police (Conduct) Regulations 2012
Supreme Court dismissed the appeal.
The Court held that the civil law test for self-defence should apply in police disciplinary proceedings, emphasizing the importance of learning, development, and maintaining public confidence.
Court of Appeal allowed the IOPC's appeal.
The Court of Appeal held that the relevant standard was whether the use of force was necessary, proportionate, and reasonable in all circumstances, and that this did not require the application of either the criminal or civil law test for self-defence.
Divisional Court allowed W80's claim for judicial review.
The Divisional Court found that the IOPC had erred in applying the civil law test and should have applied the criminal law test for self-defence.
