Reform of the law of homicide — the Law Commission's Homicide Offences Consultation Paper.
Summary
On 17 June 2026, the Law Commission (responsible for suggesting law reform to the Government) set out provisional proposals for restructuring homicide offences, with responses invited by 30 September 2026. Most significantly, it proposes replacing the current two-tier system with a three-tier structure that would make homicide law 'clearer and more coherent, whilst facilitating fairer labelling and more proportionate sentencing.'
The Current Two-Tier System
England and Wales currently have two general homicide offences: murder and manslaughter. Neither is defined by an Act of Parliament; both have been developed at common law through the courts.
Murder is the more serious. It is committed when a person unlawfully kills another, intending either to kill them or to cause grievous bodily harm (i.e. really serious injury). Anyone convicted of murder receives a life sentence; judges have no choice in the matter. They set a minimum term of imprisonment, and only after that has been served can a convicted person be considered for release.
Manslaughter is the lesser offence, covering killings where the defendant did not intend to kill or cause serious harm but was seriously at fault anyway. A person convicted of manslaughter may receive a life sentence but, unlike murder, this is not mandatory.
The Proposed Three-Tier Reform
Following widespread criticism of the current two-tier system, the Law Commission has proposed a three-tier structure: first-degree murder, second-degree murder and manslaughter.
A defendant who intended to kill would be guilty of first-degree murder, carrying a mandatory life sentence. A defendant who intended only to cause grievous bodily harm would be guilty of second-degree murder, for which life imprisonment is the maximum sentence but judges retain discretion over the sentence. Manslaughter would remain the third tier.
Alongside these offences, the Commission proposes a new verdict of 'murder with a partial defence.' At present, a defendant who intends to kill but successfully raises a partial defence such as diminished responsibility or loss of control is convicted of voluntary manslaughter. Under the proposals, the jury would instead return this new verdict, which would carry the same maximum as manslaughter does now.
Effect of the Provisional Proposals
Fair labelling and proportionate sentencing are cornerstones of the Commission's provisional proposals. A major criticism of the two-tier system is that it fails to distinguish between the conduct and culpability involved in different killings charged as murder. Someone who stabs a person in the leg intending to injure them seriously, but unexpectedly kills them, is convicted of the same offence as a contract killer. Under the proposed three-tier system, a jury would have to decide which intention the defendant had when they killed (a question currently left to judges at sentencing), and judges would also have more discretion to impose proportionate sentences.
Future Impact
If implemented, the three-tier system would bring significant changes to how homicide cases are charged, pleaded and decided. Such changes would nevertheless need to be accompanied by changes to defences and sentencing, which the Commission will address at a later stage. Whether the Government ultimately acts on any forthcoming final proposals is another matter. Responses to the Consultation Paper closed on 30 September 2026, and the Commission's recommendations will follow. An earlier attempt at this reform in 2006 proposed a similar tiered structure. The Government legislated for its recommendations on partial defences in the Coroners and Justice Act 2009 but left the restructuring of the offences untouched.
