Attorney Generals Reference No. 112 of 2009 (Church)

The label one-punch manslaughter does not itself determine sentence, since a single blow may cause death in many different circumstances. Sentence must reflect the seriousness of the particular violence, including whether the blow was unprovoked, its force and direct consequences, and any closely similar previous violence by the offender.

An early guilty plea, remorse and youth may substantially mitigate sentence. They will not prevent a sentence from being unduly lenient where a young offender delivers a full-force, unprovoked and fatal blow to the head despite already knowing, from a grave similar assault, the serious harm such violence can cause.

The Attorney General sought leave under section 36 of the Criminal Justice Act 1988 to refer as unduly lenient a sentence imposed on Darryl Church for manslaughter.

At Bristol Crown Court, after an early guilty plea, Burnett J sentenced the 18-year-old offender to 20 months’ detention. The victim died from a single, full-force punch to the head. The offender had previously committed a serious assault by a similar punch, causing unconsciousness and a fractured jaw.

The issue was whether, notwithstanding the guilty plea, remorse and youth, the 20-month sentence was unduly lenient.

1. Leave was granted and the reference succeeded. The sentence of 20 months’ detention was unduly lenient and was increased to three-and-a-half years’ detention.

2. The court applied its recent analysis in Attorney General’s Reference Nos. 60, 62 and 63 of 2009 (R v Appleby and Others) [2009] EWCA Crim 2693. The expression one-punch manslaughter is only a convenient description. It does not capture the different circumstances in which a single blow may cause death, so the sentence must be assessed by reference to the facts of the individual offence.

3. This offence was exceptionally serious. The victim had neither threatened nor provoked the offender. The offender delivered a very heavy, full-force punch to the side of the victim’s head. The blow directly caused the fatal injury, without any intervening impact with the ground or another object.

4. The offender’s previous conviction materially aggravated the case. In the earlier assault he had also delivered a heavy punch to the head, which rendered the victim unconscious and fractured his jaw. He therefore knew, or must have appreciated, the serious injury that such violence could cause.

5. The sentencing judge had correctly taken account of the early guilty plea, remorse and youth. A full guilty-plea discount was required and some allowance remained appropriate for the offender’s age. Those mitigating features could not justify the original sentence in light of the gravity of the killing and the closely similar previous violence.

1. Court of Appeal (Criminal Division) — in [2010] EWCA Crim 351, granted the Attorney General leave under section 36 of the Criminal Justice Act 1988, held the sentence unduly lenient, and increased it to three-and-a-half years’ detention.
2. Bristol Crown Court — on 19 November 2009, Burnett J sentenced the offender to 20 months’ detention following his guilty plea to manslaughter.
