Introduction

This guidance is intended to assist prosecutors in identifying the legislation available to consider when reviewing cases involving weapons and knives. Please note there is separate guidance for Firearms offences.

It is not an exhaustive account of all the offences but a guide to some key offences. It aims to assist prosecutors in selecting the appropriate charge in the circumstances of the case and sets out legislative provisions in place when considering a case involving a repeat offender.

Where an offence has been committed by a child i.e. someone aged under 18 years old, prosecutors should refer to the Children as suspects and defendants guidance. Prosecutors should also consider the Guideline on the Cautioning and Charging of Knife Crime Offences.

Selecting the most appropriate charge or charges

It is for the prosecutor to consider all the circumstances and facts of the case to arrive at a decision on the appropriate charge/s, applying the principles set out in the Code for Crown Prosecutors, in particular paragraph 6 'selection of charges'.

Prosecutors when applying the code must ensure:

that the court has adequate sentencing powers
the seriousness of the offending is considered and whether it is appropriate to reflect the carrying/use of a weapon or knife as part of other offending or a separate charge is required, to ensure the court can consider the totality of the offending

Prosecutors should ensure that a case can be presented clearly and simply for a court/jury to understand and where appropriate make use of multiple incident counts on an indictment.

Where knife point robberies are charged, prosecutors should charge a separate count for the offence of either possession of an offensive weapon or having a bladed article alongside the substantive robbery charge. This will allow the court appropriate sentencing powers and for the weapon or knife offence to be reflected on the offenders PNC. It will also ensure if offender is further convicted for the same offence the minimum sentence provisions can be applied.

The following process may assist prosecutors. First, determine what type of weapon or knife the suspect had? Second, what did they do with the weapon or knife? Third, what are the powers of sentence?

1. Determine the type of weapon or knife?

Prosecutors can refer to Annex A for definitions of different types of weapons and knives. When the police provide a file submission to the CPS this should clearly identify the type of weapon or knife which should be considered as part of a charging decision, along with the size of the blade on the weapon or knife, where appropriate.

2. What have they done with the weapon or knife?

Prosecutors should consider the evidence supplied and determine what the suspect has done with the weapon or knife. Have they simply been in possession, have they tried to sell or deliver it, have they made threats with the weapon or knife and have they used the weapon or knife. This will assist in determining the type of offence that should be charged.

3. What is the likely sentence?

Prosecutors should consider the likely sentence a suspect would receive. There may be occasion where there is overlap in offences. For example, a flick knife or gravity knife would fall within the definition under both section 1A Restriction of Offensive Weapons Act 1959, a summary only offence that carries a maximum penalty of 51 weeks imprisonment and section 1 Prevention of Crime Act 1953, an either way offence that carries a maximum penalty of 4 years' imprisonment.

There will also be occasions where the selection of a particular charge is required to ensure that the court has the powers to impose a mandatory minimum sentence or extended sentence, (see below section on ‘Mandatory minimum sentences' for where this is applicable).

Offences available

The below is a non-exhaustive list of offences available for prosecutors to consider when making a charging decision.

Summary only offences

These offences are triable only in the magistrates’ court and carry a maximum penalty of six months imprisonment.

Mandatory minimum sentence provisions apply for this offence in accordance with section 311 SA 2020. Prosecutors should see the below section titled ‘Mandatory minimum sentences’ for more detail.

Acceptability of pleas

Prosecutors should apply paragraphs 9.1 to 9.7 of the Code for Crown Prosecutors as well as the Attorney General's Guidelines on Accepting Pleas when considering acceptability of pleas.

Prosecutors should only accept the defendant’s plea if:

the court can pass a sentence that matches the seriousness of the offending, particularly where there are aggravating features, (noting any mandatory minimum sentences), and
it provides the court with adequate powers to impose other ancillary orders, bearing in mind that these can be made with some offences but not with others

Where knife point robberies are committed and a separate count has been included on the indictment alleging either possession of an offensive weapon or having a bladed article together with the substantive robbery charge a guilty plea or conviction in respect of the knife count in addition to the robbery can result in a consecutive sentence or concurrent sentences uplifted to reflect totality and if a defendant is further convicted for the same offence the minimum sentence provisions will be applied. Prosecutors should insist on guilty pleas to such counts and not to have them lie on file.

Sentencing

The Sentencing Council has published guidelines for sentencing many of these offences which can found on their website at Sentencing – Sentencing Council.

Mandatory minimum sentences

Where the offender is convicted of a second weapon or knife offence

Under section 315 SA 2020 the court must apply the mandatory minimum sentence, when an offender aged 16 or over is convicted of a second offence under the following:

section 1 PCA 1953 (possession of an offensive weapon)
section 139 CJA 1988 (possession of a bladed article)
section 139A(1) or (2) CJA 1988 (having a bladed article or offensive weapon on education premises)
section 6 OWA 2019 (having a corrosive substance in a public place)

For this to apply there must be a conviction (guilty plea or finding of guilt) for the for the first relevant offence, (see section 315(5) SA 2020 for list of relevant offences), and then the commission of the second offence must have taken place on or after 17 July 2015 for offences under section 1 PCA 1953, section 139 CJA 1988 and section 139A CJA 1988, and on or after 6 April 2022 for section 6 OWA 2019. It does not matter for the purpose of section 315 SA 2020 when the first relevant offence occurred only the second offence.

The minimum sentence will not apply if the second offence was committed whilst the offender was on bail awaiting a trial for the first offence and it does not apply it the second offence is a threatening offence.

It does not matter what age the offender was at the time of commission of the first relevant offence, but they must be 16 years or over at the commission of the second offence for the minimum sentence to be imposed.

The minimum custodial sentence is at least six months' imprisonment for an offender aged 18 or over when convicted of the index offence (detention in a young offender institution for those aged under 21), and at least a four-month detention and training order for 16- and 17-year-olds.

The judge must impose the minimum sentence unless the court is of the opinion that there are exceptional circumstances which relate to the offence, the previous offence(s), or the offender which justify not doing so.

Prosecutors should be prepared to make submissions on whether there are particular or exceptional circumstances which justify the court not imposing the minimum sentence. Any court decision on whether the minimum term should be imposed must be clearly recorded.

The power to make a community order is not exercisable in circumstances where the mandatory minimum sentence condition is met, see section 202 SA 2020.

The power to make a youth rehabilitation order is not exercisable in circumstances where the mandatory minimum sentence condition is met, see section 177 SA 2020.

However, it is possible to suspend a minimum term of imprisonment or detention in a young offender institution, but will be rare: R v Uddin [2022] EWCA 751.

Where the offender used the weapon or knife to commit an offence or commit murder

If the offender took a knife or other weapon to the scene intending to (a) commit any offence, or (b) have it available to use as a weapon and used that knife or other weapon in committing the murder, the normal starting point is 25 years for the minimum term of the life sentence. This applies to offences of murder committed from 2 March 2010 if the offender was aged 18 or over when the offence was committed (and the case does not fall within the conditions for other appropriate starting points, schedule 21 SA 2020). Prosecutors should also refer to the Homicide prosecution guidance.

Where the offender is convicted of a threatening offence

Under section 312 2020 the court must apply the mandatory minimum sentence when an offender aged 16 or over is convicted of a threatening offence under the following:

section 1A PCA 1953
section 139AA CJA 1988

There is not requirement for previous offences to have been committed.

The minimum term for offenders aged 16 or over but under 18 is a 4-month' detention and training order, offenders aged 18 or over but under 21 is a 6 month' detention and training order and offers age 21 or over a term of at least 6 months' imprisonment.

Ancillary Orders

Prosecutors should refer to the Ancillary Orders related prosecution guidance to consider appropriate orders to be made in the circumstances of the case.

Forfeiture/Deprivation

In all cases involving a weapon, knife or firearm prosecutors should seek forfeiture and destruction or deprivation order. For offences contrary to section 1 PCA 1953, section 1(2) PCA 1953 enables forfeiture and destruction of the weapon. For section 6 Knives Act 1997 (for offences committed under sections 1 and 2) and section 6 Crossbows Act 1987 contain provisions relating to forfeiture or disposal. For all other sections a deprivation order should be sought, prosecutors should refer to the provisions in sections 152-161 SA 2020.

Serious Violence Reduction Orders (SVROs) – Available in Merseyside, Sussex, Thames Valley and West Midlands

Section 342A SA 2020 makes provisions for SVROs. SVROs are civil orders made in respect of an offender convicted of an offence involving a bladed article or offensive weapon.

The purpose of the SVRO is to protect the public from the risk of harm involving a bladed article or offensive weapon, protect any particular members of the public (including the offender) from such risk, or prevent the offender from committing another offence involving a bladed article or offensive weapon.

SVROs are being piloted across Merseyside, Sussex, Thames Valley, and West Midlands over a two-year period. Following the pilot, SVROs will be independently evaluated before consideration is given to whether SVROs are rolled out nationally. The pilot is due to finish on 19 April 2025, but there is a six-month savings period during which existing orders will remain live, but no new orders may be made. This is to allow for orders made up to or on the final day of the pilot to be live for a minimum duration of six-months meaning that the use of the SVRO stop and search power will be available until 19 October 2025. After 19 October 2025 all live orders will become null and void.

SVROs can only be applied for in pilot areas; however, an officer from any police force, including British Transport Police, may exercise the power granted by the SVRO, and a breach of a SVRO can be committed and prosecuted anywhere in England and Wales.

The prosecution, either at its own initiative or following a request from the police, can make an application to the court in respect of an offender aged 18 or over who has been convicted of a relevant offence.

A relevant offence is where the court is satisfied, on the balance of probabilities, that a bladed article or offensive weapon was used by or was with the offender when the offence was committed; or another person who committed the offence used or had with them a bladed article or offensive weapon in the commission of the offence and the offender knew or ought to have known that this would be the case.

When considering a relevant offence, in DPP v Stanley [2022] EWHC 3187 (Admin), the Administrative Court held that the wording of section 19(10)(c) OWA 2019 was sufficient to cover an offence of having a bladed article in a public place under section 139(1) and (6) CJA 1988. The court also held that there is no requirement for any other offence to have been committed at the same time. The same rationale is likely to apply to SVROs.

The conditions for an SVRO are set out in section 342A SA 2020. A court can only make an SVRO in addition to dealing with the offender for the offence, but not if it makes an order for absolute discharge in respect of the offence.

Section 342G SA 2020 creates an offence of breach of a SVRO, punishable on summary conviction, to imprisonment for a term not exceeding the general limit in a magistrates’ court, a fine, or both; and on conviction on indictment, to imprisonment for a term not exceeding 2 years, a fine, or both.
