Factual and Procedural Background
This case concerns a renewed application for leave to appeal against sentence following convictions for murder and two robberies. The applicant was sentenced at Croydon Crown Court on 15 May 2024 by His Honour Judge Gower KC. The applicant pleaded guilty to the robbery offences and was convicted of murder after trial. The sentence for murder was life custody with a minimum term of 25 years and three months, less 479 days spent on remand. Sentences for the robberies were concurrent detention terms in a young offender institution. The appeal relates solely to the murder sentence.
The offences were committed on 30 December 2022 by the applicant and his younger half-brother. The brothers committed two robberies of 14-year-old victims in Peckham, involving threats and theft of mobile phones, which the applicant later sold. Subsequently, they robbed and murdered a 29-year-old man in a park by stabbing him with a large knife carried by the younger brother. The fatal blow was delivered by the younger brother. Both defendants fled without seeking help for the victim. The applicant was of previous good character and was represented pro bono in the appeal application.
Legal Issues Presented
- Whether the minimum term imposed on the applicant for murder was manifestly excessive.
- Whether insufficient regard was given to parity of sentence between the applicant and his younger half-brother.
- Whether the sentencing judge failed to adequately consider the applicant's immaturity despite his chronological age.
- Whether the judge properly accounted for the applicant's limited role as encouragement and assistance rather than direct infliction of the fatal injury.
Arguments of the Parties
Appellant's Arguments
- The applicant contended that the disparity between his sentence and that of his younger brother was unjust, given the applicant’s immaturity and the fact that the younger brother was the actual stabber.
- It was submitted that the sentencing judge gave insufficient allowance for the applicant’s emotional and developmental immaturity, which was argued to be comparable to or less than that of his younger brother.
- The applicant argued that the judge did not sufficiently differentiate his role as one of encouragement or assistance rather than direct perpetration of the murder.

Guidance on sentencing co-defendants with significant age differences, emphasizing consideration of emotional and developmental maturity over mere chronological age. |

| R v Peters, Palmer and Campbell [2005] EWCA Crim 605; [2005] 2 Cr App R(S) 101 |

| Attorney General's Reference (R v SK) [2022] EWCA Crim 1421; [2023] 1 Cr App R(S) 26 |
Reiterated that sentencing judges should adjust culpability assessments based on offender maturity, not just age. |
Supported the court’s conclusion that maturity adjustments were properly made in sentencing the applicant. |
Court's Reasoning and Analysis
The court recognised the statutory framework setting different starting points for minimum terms in murder cases committed by offenders over and under 18 years, reflecting Parliament’s intention to impose harsher sentences on adults. The starting point for the applicant (aged 19) was 30 years, and for his younger brother (under 16½), 20 years.
The court stressed that sentencing must look beyond mere chronological age to consider emotional and developmental maturity, as emphasised in the cited authorities. The sentencing judge had carefully applied this principle, explicitly referencing the recent Court of Appeal guidance in R v Kamarra-Jarra and discounting the applicant’s sentence to reflect his immaturity and to maintain some parity with his brother’s sentence.
The court noted that the age gap between the defendants in this case (approximately two and a half years) was substantial compared to the case in Kamarra-Jarra, justifying a wider disparity in sentences. The judge had also considered the applicant’s role as an encourager and assistant rather than the actual stabber, and his immaturity was well documented and factored into sentencing.
The court acknowledged the gravity of the offences, including the gratuitous nature of the murder during a robbery, the use of a large knife, the failure to seek medical assistance, and the applicant’s subsequent sale of the victim’s phone, all supporting the sentence imposed.
Ultimately, the court found no arguable error in the sentencing judge’s approach, reasoning, or application of the law and principles concerning maturity, culpability, and parity.
Holding and Implications
The court REFUSED PERMISSION TO APPEAL against the sentence imposed on the applicant for murder.
The direct consequence is that the applicant’s sentence of life imprisonment with a minimum term of 25 years and three months (less time served) stands as imposed. No new precedent was established; the decision reaffirms established principles regarding sentencing young offenders and the importance of balancing statutory starting points with considerations of maturity and parity.
