Factual and Procedural Background
On 24 January 2024, in the High Court at The City, the Plaintiff, the Defendant, and a third party were found guilty of the murder of an individual and assaulting the deceased's partner. Each was sentenced to life imprisonment with a punishment part of 18 years. The appeal concerns the legal principle of concert in homicide cases, specifically whether a jury can return a verdict of murder against one accused and culpable homicide against another for the same act. The Plaintiff also appealed against sentence.
The events leading to the crime involved the Defendant suspecting the deceased of theft and enlisting a third party to recover the stolen items. The group, including the Plaintiff, planned to "sort out" the deceased and "give him a doing" or "a beating," anticipating the presence of the deceased's partner at the address. They traveled to the deceased's flat carrying a toolbox with various tools that could be used as weapons. The deceased was attacked with multiple weapons, sustaining numerous injuries, resulting in death due to a penetrating stab wound. The murder weapon was not recovered, but evidence suggested the Defendant's close involvement in the fatal attack. The Plaintiff disposed of potential evidence during their return journey.
Legal Issues Presented
- Whether a jury can return a verdict of murder against one accused and a verdict of culpable homicide against another in the context of concerted action in homicide cases.
- Whether the trial judge erred in directing the jury that they could not convict one accused of murder and the others of culpable homicide.
- Whether the sentencing of the Plaintiff to the same punishment part as co-accused was appropriate given their respective roles in the crime.
Arguments of the Parties
Second Appellant's Arguments
- Relied on precedent establishing that different verdicts (murder and culpable homicide) are permissible among co-accused in concert cases.
- Argued that the trial judge removed the jury's discretion to convict ancillary actors of culpable homicide while convicting the principal actor of murder.
- Accepted that the principal actor's guilt depends on individual criminal intent, but ancillary actors' guilt should be assessed objectively based on the common plan and foreseeability of homicide.
- Submitted that ancillary actors could be convicted of culpable homicide if they did not foresee the use of lethal weapons or serious injury.
- Contended that the trial judge's directions were erroneous by applying an "all or nothing" approach to ancillary actors.
First Appellant's Arguments
- Accepted that if concert is established, ancillary actors' guilt is linked to the common criminal purpose, assessed objectively.
- Argued that ancillary actors should be acquitted or convicted of culpable homicide if serious injury was not foreseeable, even if the principal actor was guilty of murder.
- Maintained that the mens rea of ancillary actors must be considered to avoid unfairness.
- Submitted that the trial judge misunderstood relevant precedent by limiting culpable homicide to the principal actor's guilt.
- Emphasized the absence of evidence that the Plaintiff knew about lethal weapons or assaulted the deceased, supporting the availability of culpable homicide as an alternative verdict.
Crown's Arguments
- Presented detailed analysis of institutional writers and case law supporting that art and part guilt extends to all participants in a common criminal purpose involving foreseeable acts.
- Asserted that there is generally no basis for different homicide verdicts among co-accused acting in concert.
- Reviewed historical and modern case law, noting some conflicting authorities but ultimately supporting that ancillary actors share the same guilt as the principal actor if serious injury was foreseeable and within the common plan.
- Highlighted that differentiated verdicts are exceptions, typically arising in spontaneous concert cases or where diminished responsibility or provocation apply.
- Argued that in this case, the appellants participated in antecedent concert with a common plan involving serious violence, making murder verdicts inevitable for all.
- Addressed sentencing, supporting equal punishment parts based on shared responsibility in the premeditated attack.

Application by the Court |
| McKinnon v HM Advocate 2003 JC 29 |
Law of concert in homicide; objective test for ancillary actors' guilt; possibility of differentiated verdicts |
Recognized as largely correct but critiqued for illogical allowance of differentiated verdicts; court affirmed no separate mens rea for ancillary actors once concert established. |
| Brown v HM Advocate 1993 SCCR 382 |
Requirement of caution before withdrawing alternative verdicts; assessment of mens rea of ancillary actors |
Court found trial judge erred in withdrawing culpable homicide; emphasized jury's role in assessing degree of wicked recklessness. |
| Melvin v HM Advocate 1984 SCCR 113 |
Validity of different verdicts for co-accused; concert liability |
Verdict allowing murder and culpable homicide upheld but considered unusual and illogical foundation for law change. |
| Docherty v HM Advocate 1945 JC 89 |
Objective test for foreseeability of lethal weapon use; art and part liability |
Established that all acting in concert with expectation of lethal weapon use are guilty of murder; foundational for court's reasoning. |
| Carey v HM Advocate 2016 SCCR 148 |
Inconsistency of culpable homicide verdict in concert with murder; principle of art and part guilt |
Supported view that culpable homicide verdict inconsistent if co-accused objectively associated with lethal force. |
| Andonov v HM Advocate 2013 SCCR 245 |
Sentencing principle that participants in contract killings are equally responsible |
Applied to affirm equal punishment parts in antecedent concert cases like the present. |
| Cosgrove v HM Advocate 2008 JC 102 |
Consideration of materially subsidiary roles in sentencing |
Referenced in sentencing appeal to assess whether different punishment parts were justified. |
| Rauf v HM Advocate 2020 SCCR 47 |
Application of sentencing principles in antecedent concert murders |
Supported trial judge's approach to sentencing in the present case. |
| Hopkinson v HM Advocate 2009 SCCR 225 |
Possibility of different verdicts in joint attacks |
Noted as an exception involving spontaneous concert; distinguished from the present antecedent concert case. |
Court's Reasoning and Analysis
The court began by affirming the established principle that in cases of concert, the principal actor's guilt depends on their individual mens rea, while ancillary actors' guilt is determined objectively by their participation in a common criminal purpose and what serious consequences were foreseeable within that purpose. The court reviewed the trial judge's directions, which correctly explained these principles, including the application of the principle of concert to murder and culpable homicide.
The court analysed the conflicting case law, particularly McKinnon, Brown, and Melvin, identifying inconsistencies and logical errors in allowing different homicide verdicts among co-accused acting in concert. It determined that once a murder is committed pursuant to a common criminal purpose involving foreseeable serious injury, all participants who actively associated themselves with that purpose are guilty of murder. The mens rea of ancillary actors at the time of the fatal act is irrelevant in such cases.
The court rejected the argument that culpable homicide could be an alternative verdict for ancillary actors in the presence of a murderous principal actor, except in limited circumstances such as diminished responsibility or provocation. It emphasized that allowing different verdicts in antecedent concert cases undermines the principles of art and part liability.
Regarding sentencing, the court considered the Plaintiff's role, including participation in planning and execution, disposal of evidence, and assistance in the attack. It found no basis to differentiate punishment parts among the appellants, affirming the trial judge's approach based on comparative justice principles.
Holding and Implications
The court REFUSED the appeals against conviction and sentence.
The holding confirms that in antecedent concert homicide cases, all participants who foreseeably associate with a plan involving serious violence leading to death are guilty of murder, regardless of their individual mens rea at the time of the fatal act. Differentiated verdicts of murder and culpable homicide among co-accused in such cases are generally impermissible. This decision reinforces the objective test for art and part liability and clarifies the limits of jury discretion in delivering verdicts in concerted homicide cases. The sentencing implication is that participants in a premeditated fatal attack should generally receive equal punishment parts unless exceptional circumstances justify differentiation. No new precedent was established beyond the clarification and reaffirmation of existing principles.
