Manslaughter by reason of loss of control

Common law, Coroners and Justice Act 2009, ss 54 and 55

Effective from 01 November 2018

Triable only on indictment
Maximum: Life imprisonment
Offence range: 3 – 20 years’ custody

This is a Schedule 19 offence for the purposes of sections 274 and 285 (required life sentence for offence carrying life sentence) of the Sentencing Code.

For offences committed on or after 3 December 2012, this is an offence listed in Part 1 of Schedule 15 for the purposes of sections 273 and 283 (life sentence for second listed offence) of the Sentencing Code.

This is a specified offence for the purposes of sections 266 and 279 (extended sentence for certain violent, sexual or terrorism offences) of the Sentencing Code.

The type of manslaughter (and thereby the appropriate guideline) should have been identified prior to sentence. If there is any dispute or uncertainty about the type of manslaughter that applies the judge should give clear reasons for the basis of sentence.

User guide for this offence


Guideline users should be aware that the Equal Treatment Bench Book covers important aspects of fair treatment and disparity of outcomes for different groups in the criminal justice system. It provides guidance which sentencers are encouraged to take into account wherever applicable, to ensure that there is fairness for all involved in court proceedings.

Step 1 – Determining the offence category

Culpability

The characteristics set out below are indications of the level of culpability that may attach to the offender’s conduct; the court should balance these characteristics to decide which category most resembles the offender’s case in the context of the circumstances of the offence. The court should avoid an overly mechanistic application of these factors.

A - High culpability

  • Planning of criminal activity (including the carrying of a weapon) before the loss of control
  • Offence committed in the context of other serious criminal activity
  • Use of a firearm (whether or not taken to the scene)
  • Loss of self-control in circumstances which only just met the criteria for a qualifying trigger
  • Concealment, destruction, defilement or dismemberment of the body (where not separately charged)

B - Medium culpability

Cases falling between high and lower because:

  • factors are present in high and lower which balance each other out and/or
  • the offender’s culpability falls between the factors as described in high and lower

C - Lower culpability

  • Qualifying trigger represented a very high degree of provocation

Harm

For all cases of manslaughter the harm caused will inevitably be of the utmost seriousness. The loss of life is taken into account in the sentencing levels at step two.

Step 2 – Starting point and category range

Having determined the category at step one, the court should use the corresponding starting point to reach a sentence within the category range in the table below. The starting point applies to all offenders irrespective of plea or previous convictions.

An adjustment from the starting point, upwards or downwards, may be necessary to reflect particular features of culpability (for example, the presence of multiple factors within one category, the presence of factors from more than one category (where not already taken into account at step 1), or where a case falls close to a borderline between categories).

Culpability
A B C
Starting point
14 years’ custody
Starting point
8 years’ custody
Starting point
5 years’ custody
Category range
10 – 20 years’ custody
Category range
5 – 12 years’ custody
Category range
3 – 6 years’ custody

Note: The table is for a single offence of manslaughter resulting in a single fatality. Where another offence or offences arise out of the same incident or facts, concurrent sentences reflecting the overall criminality of offending will ordinarily be appropriate: please refer to the Totality guideline and step six of this guideline.

The tables below contain a non-exhaustive list of additional factual elements providing the context of the offence and factors relating to the offender. Identify whether any combination of these, or other relevant factors, should result in a further upward or downward adjustment. In some cases, having considered these factors, it may be appropriate to move outside the identified category range.

Care should be taken to avoid double counting factors already taken into account in assessing culpability or in the finding of a qualifying trigger

Factors increasing seriousness

Statutory aggravating factors:

  • having regard to a) the nature of the offence to which the conviction relates and its relevance to the current offence; and b) the time that has elapsed since the conviction (See step five for a consideration of dangerousness)

Other aggravating factors:

  • History of violence or abuse towards victim by offender (which may include coercive or controlling behaviour)
  • Use of strangulation, suffocation or asphyxiation
  • Involvement of other(s) through coercion, intimidation or exploitation
  • Significant mental or physical suffering caused to the deceased
  • Persistence of violence

Factors reducing seriousness or reflecting personal mitigation

  • Intention to cause serious bodily harm rather than to kill
  • History of significant violence or abuse towards the offender by the victim (which may include coercive or controlling behaviour)
  • Violence initiated by the victim

Step 3 – Consider any factors which indicate a reduction for assistance to the prosecution

The court should take into account section 74 of the Sentencing Code (reduction in sentence for assistance to prosecution) and any other rule of law by virtue of which an offender may receive a discounted sentence in consequence of assistance given (or offered) to the prosecutor or investigator.

Step 4 – Reduction for guilty pleas

The court should take account of any potential reduction for a guilty plea in accordance with section 73 of the Sentencing Code and the Reduction in Sentence for a Guilty Plea guideline.

Step 5 – Dangerousness

The court should consider:

1) whether having regard to the criteria contained in Chapter 6 of Part 10 of the Sentencing Code it would be appropriate to impose a life sentence (sections 274 and 285)

2) whether having regard to sections 273 and 283 of the Sentencing Code it would be appropriate to impose a life sentence.

3) whether having regard to the criteria contained in Chapter 6 of Part 10 of the Sentencing Code it would be appropriate to impose an extended sentence (sections 266 and 279)

When sentencing offenders to a life sentence under these provisions, the notional determinate sentence should be used as the basis for the setting of a minimum term.

Step 6 – Totality principle

If sentencing an offender for more than one offence, or where the offender is already serving a sentence, consider whether the total sentence is just and proportionate to the overall offending behaviour in accordance with the Totality guideline.

Step 7 – Compensation and ancillary orders

In all cases the court should consider whether to make compensation and/or other ancillary orders.

Step 8 – Reasons

Section 52 of the Sentencing Code imposes a duty to give reasons for, and explain the effect of, the sentence.

Step 9 – Consideration for time spent on bail (tagged curfew)

The court must consider whether to give credit for time spent on bail in accordance with section 240A of the Criminal Justice Act 2003 and section 325 of the Sentencing Code.
