R v Leon Murray

An appellate court will not interfere with a sentencing judge’s assessment where the conclusion was open on the evidence and was neither wrong nor unreasonable. A murder minimum term may properly be increased from the 15-year starting point by serious aggravating features, including significant premeditation and a sustained knife attack in a domestic setting. Mental-health conditions or neurodevelopmental traits will mitigate only where they have a sufficient connection with the offending. A separate manslaughter count following a murder conviction should lie on the file on the usual terms, rather than attract no separate penalty.

The applicant was convicted of murder after the jury rejected his account of an attack and his partial defence of diminished responsibility. The Crown Court imposed imprisonment for life with a 20-year minimum term, reduced by 578 days served on remand, and imposed no separate penalty for a manslaughter count. A single judge refused leave to appeal against sentence. On renewal, the applicant relied on his mental health, effective good character, earlier admission of causing the death and alleged lack of premeditation. The Court of Appeal also considered the correct disposal of the manslaughter count.

Sentence. The renewed application for leave to appeal sentence was refused. The sentencing judge had heard the medical evidence at trial and was entitled to conclude that the applicant’s complex PTSD and autistic traits had no sufficient connection with the offending and did not reduce its seriousness. That conclusion was open on the evidence and could not be criticised as wrong or unreasonable.

1. The offence involved a serious and violent attack on the applicant’s partner, with 17 knife wounds. The domestic setting, the family context, the presence of the very young child and the evidence of significant premeditation were aggravating features.
2. Those aggravating features justified a substantial increase from the 15-year starting point. The matters relied on in mitigation, including effective good character, the earlier acceptance that the applicant had caused the death and his mental health difficulties, carried materially less weight. The resulting 20-year minimum term could not be faulted.
3. Count 2 disposal. The court corrected an error identified by the Registrar. Following the authority of R v Butler [2023] EWCA Crim 676, the manslaughter count should lie on the file on the usual terms, rather than attract no separate penalty. The no-separate-penalty disposal was quashed. Count 2 was directed to lie on the file, not to be proceeded with without leave of the Court of Appeal.

The sentence on Count 1 remained imprisonment for life with a minimum term of 20 years less 578 days, namely 18 years and 152 days.

• Court of Appeal (Criminal Division) — The renewed application for leave to appeal sentence was refused. The disposal of the manslaughter count was varied by substituting an order that it lie on the file: [2025] EWCA Crim 429.
• Crown Court at Wood Green — The applicant was convicted of murder and sentenced to imprisonment for life with a 20-year minimum term, less 578 days served on remand. No separate penalty was imposed for manslaughter.
• Single judge — Leave to appeal against sentence was refused.
