Single Justice Procedure (SJP) explained
A Single Justice Procedure Notice is a court document, not an informal warning. This guide explains how written motoring cases work, the 21-day response deadline, pleading choices, licence risks, evidence, mitigation and when a conventional hearing may be needed.
Who this applies to
The law explained
The Single Justice Procedure was created by sections 16A to 16F of the Magistrates' Courts Act 1980, inserted by the Criminal Justice and Courts Act 2015. In England and Wales, it provides a streamlined route for certain adult defendants charged with low-level, non-imprisonable summary offences. Many road traffic allegations fall within it. Rather than beginning with an attended hearing before a bench of magistrates, the case may be considered privately by one magistrate, assisted by a legal adviser, on the written prosecution material and the defendant's written response.
An SJPN is a formal notice of criminal proceedings. It normally identifies the charge, gives a summary of the alleged facts, includes or refers to the evidence relied on, and explains how to respond. The fact that the process is paper-based does not lower the prosecution's burden of proof. Where guilt is contested, the prosecution must still prove the offence so that the court is sure of guilt. A single magistrate should not simply accept an allegation because it has been made.
The notice generally gives three broad routes: a guilty plea, a not-guilty plea, or a guilty plea accompanied by written mitigation. A guilty plea means accepting the offence as charged. Written mitigation does not undo guilt and is not a defence; it gives context relevant to sentence, such as a genuinely isolated lapse, a previously clean record, financial circumstances, or other matters that reduce culpability or demonstrate impact. An early guilty plea normally receives sentencing credit, although the precise outcome remains a matter for the court.
A not-guilty plea takes the case out of the Single Justice Procedure. A disputed case needs a conventional court process because the parties may need to identify the real issues, consider further evidence, challenge evidence and, where appropriate, call witnesses. The court will list a hearing rather than decide guilt merely from the original papers. A person may also ask for a traditional hearing in open court even where they intend to plead guilty, particularly if the circumstances or likely licence consequences require explanation in person.
Cases commonly begin after an automated camera allegation, a police report, a roadside stop, a failure to respond adequately to a request to identify a driver, or checks involving insurance, tax or MOT status. The contents of the bundle matter. For example, the date, location, vehicle registration, speed limit, identity evidence, wording of a requirement, service details and any documentary records may all be significant depending on the offence. A statement of facts is the prosecution's account, not a finding made by the court.
Defences depend on the specific charge. A factual error, unreliable identification, an incorrect legal element, a valid insurance position, or a failure by the prosecution to prove an essential part of its case can matter. However, inconvenience, a need for a licence, an otherwise good driving history, or ignorance of the law will not normally amount to a defence. Those factors may instead be mitigation after a guilty plea. It is important not to confuse an explanation for what happened with a legal answer to the charge.
The procedure does not create a lesser form of conviction. An endorsable offence dealt with under the SJP can result in the same penalty points and financial orders as it could in an ordinary magistrates' court. If a disqualification is realistically in issue, including because points would bring a driver to the totting-up threshold, the matter is normally referred for a conventional hearing. This gives the defendant an opportunity to attend and, where relevant, advance an exceptional hardship argument before any disqualification is imposed.
Deadlines you must not miss
21 days to respond
You normally have 21 days from the date on the Single Justice Procedure Notice to enter your plea, online or by post. The clock runs from the date of the notice, not the day it is opened or read. Check the notice immediately, especially if it arrived late, was forwarded from an old address or relates to a company, hire vehicle or another person connected with the vehicle.
A response should be submitted early enough to avoid technical or postal problems. Keep a copy, screenshot or confirmation reference showing the plea entered and the date of submission. A late response may still be considered in some circumstances, but it is not safe to assume that the case will wait.
Respond before the case is decided
If no response is received within the response period, the court can treat the case as ready to decide and a single magistrate may convict and sentence in the defendant's absence on the prosecution's evidence. There is no requirement for the court to telephone or send a further informal reminder before deciding the case.
Responding does not mean accepting guilt. A not-guilty plea or a request for an open-court hearing puts the court on notice that the matter should not simply be resolved on the original papers. Even where a guilty plea is intended, means information and mitigation can materially affect the financial result and the court's understanding of the case.
Ask for a court hearing in good time
If a traditional hearing in open court is preferred, this can be requested on the response form. The request should be made within the response window. A hearing may be useful where the allegation is disputed, mitigation is substantial or sensitive, a driving ban may be in issue, or the defendant wants to address the court directly.
A timely request is much easier for the court to administer than a request made after a decision has been recorded. Once an SJP conviction has been imposed, different procedures may be needed to ask the court to revisit it, and those procedures are not a substitute for responding to the notice.
Six-month commencement limit
As with other summary offences, proceedings must generally be started within six months of the alleged offence. The important legal question is usually when proceedings were commenced, rather than when the SJPN was delivered or when a court eventually considered it.
If the notice appears to concern an event well outside that window, the dates should be checked carefully against the charge and the paperwork. Time-limit rules can be more complicated for some statutory road traffic matters, so a date issue may require legal advice rather than an assumption that a late-looking notice is automatically invalid.
Act promptly after an outcome
The outcome notice should be read as soon as it arrives. It will state the conviction, financial orders, any penalty points and payment arrangements. If the case was decided without a response because the notice was not received, was sent to an old address, or there was another genuine procedural problem, prompt action is important.
There may be limited mechanisms for asking the magistrates' court to reopen or set aside a decision, and an appeal may sometimes be available. The right route depends on how the case was dealt with and why the result is challenged. Keeping envelopes, address evidence and copies of all communications can be useful.
Penalties
Income-based fines
The single magistrate applies the same Sentencing Council approach to fines as an ordinary magistrates' court. Fines are generally linked to weekly relevant income and the seriousness of the offence. The court considers culpability, harm and applicable aggravating or mitigating features, rather than treating every allegation of the same type identically.
The means section is therefore important. Accurate income, benefits and financial information help the court set a proportionate fine. If no reliable information is supplied, the court may make an income assumption that produces a higher fine than the defendant's actual circumstances would justify. Deliberately inaccurate means information can create further problems.
Penalty points
Endorsable offences dealt with under the SJP still carry points, usually 3 to 6 depending on the offence, recorded on the driving record exactly as they would be after a courtroom hearing. The procedure is quicker and normally does not involve attendance, but it does not reduce the endorsement consequences.
Existing live points should be checked before a plea is entered. Points can affect insurance premiums and, where the total reaches the relevant threshold, can lead to a totting-up disqualification process. The court's outcome notice should be retained and the driving record checked after the case has been processed.
Failure to identify the driver
If the matter relates to not naming the driver under section 172, conviction typically brings 6 points and a fine. This can be more damaging to a licence than the underlying speeding allegation that prompted the request for driver information.
These cases may involve issues about service of the request, who was responsible for responding, the information actually supplied and what reasonable steps were taken. A person who did respond, was not the relevant keeper, or has proof of posting or electronic correspondence should not assume that the statement of facts tells the whole story. The precise legal position depends on the circumstances.
No insurance penalties
Driving without insurance is treated severely even in the SJP. It carries 6 to 8 points and, in some cases, a discretionary disqualification, plus a fine. Insurance cases can be deceptively complex: an insurance database result, for example, may not by itself answer every question about the actual policy, driver, vehicle or permitted use.
Where disqualification is a realistic outcome, or where the defendant disputes being uninsured, a conventional hearing may be needed. Relevant documents can include the policy schedule, certificate, correspondence with the insurer, proof of cancellation or renewal, and evidence about the purpose for which the vehicle was being used. A belief that insurance existed is not always enough, but the facts can matter greatly.
Surcharge and costs
On top of any fine, a convicted defendant will normally pay a victim surcharge and a contribution to prosecution costs. These additions apply to SJP convictions just as they do in open court. The total payable can therefore be substantially higher than the headline fine shown in general penalty guidance.
The outcome notice explains payment arrangements. Financial difficulty does not remove the need to engage with the court, but it is relevant to means assessment and may be relevant when payment arrangements are considered. Ignoring the order can lead to enforcement action.
Referral out if a ban looms
If a guilty plea would trigger a totting-up disqualification, the case is normally lifted out of the SJP and listed for a conventional hearing. This is intended to protect the opportunity to attend and make representations before a ban is imposed.
At such a hearing, the court may need to consider the accurate points position and any exceptional hardship argument. Ordinary inconvenience, such as difficulty getting to work, is not automatically exceptional hardship. Evidence about the practical impact, particularly on dependants, employees or others, may be relevant. The court ultimately decides whether the statutory consequences apply.
Insurance and licence consequences
An SJP conviction is a court conviction. The endorsement is recorded in the same way as one imposed after an attended hearing, and insurers commonly ask about motoring convictions and penalty points when quoting, renewing or making policy changes. The policy's own disclosure wording governs what must be declared.
Drivers should not assume that a paper-based decision is invisible to insurers or DVLA. It may also matter to an employer, fleet operator or professional body where there is a contractual duty to report motoring matters. The relevant contractual and policy wording should be checked rather than guessed.
What happens, step by step
1. The SJPN arrives
You receive a bundle containing the written charge, a statement of facts, prosecution material and plea and means forms, or instructions for responding digitally. First check the name, address, vehicle registration, alleged date, location and offence. Do not assume a notice is correct simply because it has been issued by a court.
Read the entire pack, including any attached witness statements, photographs, certificates or correspondence. Identify the response deadline and keep the envelope if delayed delivery may be relevant. If the notice concerns a company, hire vehicle or former address, establish who is named as the defendant before replying.
2. Check the allegation and your driving position
Compare the prosecution account with what is actually known. For a camera allegation, consider identification and the relevant road details. For a section 172 matter, find the original request and any response. For insurance, locate the complete policy documents and insurer correspondence. Preserve documents rather than relying on memory.
Also check the current driving record and calculate the likely effect of any new points. A person close to 12 points within three years may face a very different process from a person with a clear licence. New drivers should also understand that endorsement consequences can be especially significant to their licence position.
3. Decide whether the allegation is accepted
The essential choice is whether to plead guilty or not guilty. A guilty plea accepts the charge. A not-guilty plea means the allegation is disputed and the case should proceed outside the paper process to a court hearing. A plea should reflect the actual legal and factual position, not merely the wish to avoid inconvenience.
Where the case is accepted but there are personal circumstances the court should know, the response can include mitigation. It is possible to accept responsibility while explaining relevant context. It is not appropriate to use mitigation to make factual claims that are inconsistent with a guilty plea unless the legal implications have been understood.
4. Consider whether an open-court hearing is needed
A defendant can ask for a conventional hearing rather than a Single Justice Procedure decision. This may be appropriate where evidence needs testing, the facts are disputed, detailed mitigation cannot be explained adequately in writing, or disqualification and exceptional hardship may arise.
A hearing request is not an admission of guilt and does not itself create a defence. It changes the forum in which the case is considered. The request should be made within the stated response period, with the paperwork retained.
5. Complete the plea, mitigation and means response
Responses can normally be made through the GOV.UK respond-to-court service or by returning the paper forms supplied. Complete all relevant sections carefully. Online submission may be convenient, but it is still a formal court response; review each answer before submitting it.
Mitigation is most useful when it is concise, specific and supported where possible. The means form should be completed honestly because the court uses it when assessing a fine. Keep screenshots, copies and proof of posting or submission.
6. The court considers the papers
For an SJP-eligible guilty plea, a single magistrate sits with a legal adviser and considers the charge, prosecution material, plea, mitigation and means information. The prosecutor is not present during that paper decision, and the defendant does not attend.
If the court cannot properly deal with the matter under the SJP, it can refer it for an ordinary hearing. A not-guilty plea will normally lead to a hearing because a contested allegation requires a process in which the evidence can be addressed.
7. Receive and check the outcome
The court sends written notification of its decision. This should state whether there has been a conviction, the fine, prosecution costs, victim surcharge, any points and the payment arrangements. Read it carefully rather than focusing only on the total amount due.
Check that the endorsement and offence correspond with the notice and that the points position is understood. Keep the outcome with the original SJPN and response confirmation. It may be needed for insurance disclosure, an employer, a licence query or any later procedural application.
8. Deal with payment, records and disclosure
Pay according to the arrangements in the court order or contact the relevant court service promptly if payment is difficult. Ignoring a financial order can lead to enforcement. A person should also check the driving record after sufficient processing time to ensure the endorsement position is understood.
Insurance questions should be answered according to the insurer's wording and required timing. Company-car drivers and employees with a contractual reporting obligation may need to notify the relevant fleet manager or employer. These are separate obligations from the court process.
9. Act quickly if there is a procedural problem
If the outcome was unexpected because the notice was never received, a response was not recorded, the wrong person was charged, or the plea was entered in error, obtain the documents and act promptly. Do not simply withhold payment or ignore subsequent correspondence.
There can be limited routes to ask for a case to be reopened or set aside, and an appeal may be possible in some circumstances. The correct route is dependent on the facts and the procedural history, so timely legal advice can be valuable.
Practical steps to take now
Read every page on the day the notice arrives
Identify the allegation, the evidence, the date of the notice and the response deadline immediately. SJP cases can progress without attendance, so a notice that is put aside can become a conviction before the recipient has explained anything.
Check the live points on the driving record
Use the GOV.UK view-your-driving-licence service to establish how many points are live and what this allegation could add. This is essential where the total may reach 12 points within three years, because that can change the case from a routine paper matter into a possible disqualification hearing.
Match the prosecution account against original records
Check dates, locations, registration marks, names and the allegation's core facts. Find original notices, insurance documents, MOT records, tax records, work logs, photographs and messages that may clarify what occurred. The court will not know about material that is never raised.
Separate a defence from mitigation
A defence challenges whether the offence is proved or whether legal responsibility arises. Mitigation accepts the offence but explains sentence-related circumstances. Keeping those concepts separate helps prevent an inconsistent response that accidentally admits an allegation while trying to dispute it.
Use clear, evidenced written mitigation
If pleading guilty, state relevant facts plainly: a clean record, a one-off lapse, genuine financial circumstances, caring responsibilities or other concrete consequences. Attach or retain supporting material where appropriate. General statements that a licence is important carry less weight than an accurate explanation of actual impact.
Complete the means section accurately
Provide truthful income and financial details so the court can assess an income-based fine fairly. Leaving the section blank can lead to an assumed income figure and a larger fine. Keep documents such as payslips, benefit statements or accounts in case they are needed.
Request a hearing where papers are not enough
Ask within the response period for an open-court hearing if the facts are disputed, the mitigation is complex, documents or witnesses matter, or a ban may arise. This preserves the opportunity for the case to be considered in a forum where the defendant can attend.
Save proof of the response
Take screenshots of online submissions and save any confirmation reference. For a postal response, retain a full copy and proof of posting. This evidence can be important if the court later records no response or if there is a dispute about what was submitted.
Check insurance and employment reporting duties
Read the relevant insurance policy and employment or fleet rules rather than assuming disclosure is only required at renewal. An SJP outcome can create separate contractual obligations even though the court process itself was conducted in writing.
Common mistakes
Treating the SJPN as junk mail
Because there is no immediate courtroom date, recipients sometimes mistake the notice for an administrative letter or leave it unopened. The consequence can be conviction, points and financial orders made in their absence after the 21 days has passed.
An SJPN is a court document. Opening it promptly and recording the deadline is the simplest way to avoid losing the chance to respond.
Pleading guilty online without checking totting
The online process is designed to be straightforward, which can encourage a quick response without checking existing endorsements. A guilty plea may add points that bring the total to 12 within three years and lead to a disqualification process.
Checking the driving record first allows the defendant to identify whether a conventional hearing and an exceptional hardship argument may become relevant. The existence of hardship does not itself provide a defence to the original offence.
Assuming the statement of facts is the court's finding
The statement of facts is the prosecution's summary, not an independent decision. People sometimes accept errors in it because it appears in official-looking paperwork, even where documents they hold tell a different story.
Dates, identity, service, vehicle details and policy information can matter. If there is a genuine dispute, it needs to be raised through the plea and court process rather than merely mentioned informally after conviction.
Leaving the means section blank
Some people consider income information private or assume it is irrelevant to a motoring case. In fact, fines are generally income-based, and the court needs reliable information to assess them proportionately.
Missing information can lead to an assumed income and a higher fine. Accurate completion is not an attempt to avoid responsibility; it is part of enabling an appropriate sentence.
Using mitigation as if it were a legal defence
A need for a car, a difficult journey, work pressure or a previously clean record may explain why the outcome matters, but normally does not prove that no offence occurred. Confusing these points can lead someone to enter a not-guilty plea with no viable defence.
Conversely, a person with a real factual or legal dispute may wrongly plead guilty because they believe the court will sort it out through mitigation. The plea decision should follow the evidence and law, not just personal circumstances.
Ignoring a section 172 allegation
A failure-to-identify allegation is sometimes viewed as less serious than the original camera offence. Conviction typically brings 6 points and a fine, which can be more severe for the licence than the suspected underlying offence.
People may also overlook proof that they replied, or fail to find the original request and correspondence. These records can be central to understanding the allegation and any available response.
Assuming a paper decision is less serious
The absence of a courtroom appearance can make an SJP feel informal. It is not. A conviction can carry the same driving-record, financial, insurance and employment consequences as a conviction following an attended magistrates' court hearing.
The process is different, not the legal significance of the outcome. It deserves the same careful preparation as any other criminal court notice.
Waiting until after conviction to ask for a hearing
Recipients sometimes decide only after receiving the result that they wanted to speak to magistrates. By then the case may already have been determined, and correcting the position can require separate procedural steps.
Where an attended hearing is likely to be important, it should be requested in the original response within the stated period. This is especially relevant where disqualification or detailed evidence is in issue.
When to get professional help
Many one-off cases can be understood and answered without representation, particularly where the allegation is accepted, the evidence is clear, the likely points will not create a licence problem and the mitigation is straightforward. The position is different where the proposed endorsement could take a driver to 12 points within three years. A totting-up disqualification is a major consequence, and an exceptional hardship argument is fact-specific: it concerns consequences going beyond the ordinary hardship expected from losing a licence, often including effects on other people.
Advice can also be important where the allegation is driving without insurance or failing to identify the driver under section 172. These offences often turn on technical facts: who received a notice, what response was sent, whether it was received, who was insured to drive, the policy terms, and whether a statutory defence may arise. A person who was not the driver, who was using a company or hire vehicle, or who has correspondence showing an earlier response should preserve it and consider obtaining advice before choosing a plea.
A conventional hearing may be more appropriate where the account cannot sensibly be put in a short online box, where documents or witnesses need to be considered, where there is a factual dispute, or where the result could affect work, immigration status, professional registration or a livelihood. A regulated motoring solicitor can assess the evidence, explain the realistic options and help distinguish mitigation from a viable defence. Legal advice cannot guarantee an outcome, but it can reduce the risk of making an irreversible written admission without understanding its consequences.
Prompt help is also sensible after a conviction in absence, an unexpected number of points, a missed notice due to an old address, or an online response made by mistake. There can be routes to ask a magistrates' court to revisit a case or to appeal, but they are procedural and fact-sensitive. Delay can make the position harder to correct.
Frequently asked questions
What is the Single Justice Procedure?
The Single Justice Procedure, or SJP, is a way for magistrates' courts in England and Wales to deal with certain adult, non-imprisonable summary offences in writing. It was introduced by sections 16A to 16F of the Magistrates' Courts Act 1980.
A single magistrate, assisted by a legal adviser, considers the prosecution material and the defendant's response without the defendant or prosecutor attending. It is a real criminal court procedure: any conviction, fine and penalty points have the same legal effect as if the case had been dealt with at an ordinary magistrates' court hearing.
How long do I have to respond to an SJPN?
You normally have 21 days from the date printed on the Single Justice Procedure Notice. The deadline runs from the notice date, rather than the date on which it was actually opened, so delayed post should be dealt with promptly.
A response can normally be made online through the GOV.UK respond-to-court service or by using the paper forms supplied. Keep proof of submission. If no response is made, the court can decide the case in absence.
Can I plead not guilty under the Single Justice Procedure?
Yes. A not-guilty plea can be entered using the response process. The case should then be removed from the paper procedure and listed for a conventional court hearing, because a contested allegation may require evidence to be tested.
The prosecution must prove guilt so that the court is sure. A not-guilty plea is appropriate where there is a genuine factual or legal dispute, rather than simply because the likely sentence would be inconvenient. Advice may help where the evidence or legal position is unclear.
Can I ask for a normal court hearing even if I accept the offence?
Yes. A defendant can ask for the case to be heard in open court rather than decided under the SJP. This may be useful where mitigation is complex, personal circumstances are sensitive, or the person wants to address the court in person.
The request should be made within the response window. It does not change the charge or guarantee a particular sentence, but it allows the case to be considered through the ordinary attended court process.
Can I be disqualified under the Single Justice Procedure?
If a guilty plea would result in disqualification, for example through reaching 12 points, the case is normally taken out of the SJP and listed for a conventional hearing. This allows the defendant to attend before a ban is imposed.
The court may then consider any exceptional hardship argument. Exceptional hardship is not simply the normal inconvenience of losing a licence; the court considers the actual evidence and consequences in the particular case. It does not determine guilt of the underlying offence.
What happens if I ignore an SJPN?
Ignoring the notice does not stop the prosecution. Once the response period has passed, a single magistrate can decide the case without hearing from the defendant, relying on the prosecution evidence and statement of facts.
The result may include conviction, a fine, prosecution costs, a victim surcharge and penalty points. If the notice was not received or there was a genuine reason no response could be made, it is important to obtain advice and contact the court promptly after learning of the outcome.
What should I write in mitigation for an SJP guilty plea?
Mitigation should be truthful, relevant and specific. It can explain matters such as a previously clean driving record, a one-off lapse, genuine financial circumstances, caring obligations, or other consequences that go beyond a vague assertion that driving is important.
It should not deny the essential facts of an offence after a guilty plea has been entered. Where possible, factual claims should be capable of support by documents. The magistrate considers mitigation alongside the offence seriousness and the defendant's means.
What if I was driving a company car or a hire vehicle?
Company and hire vehicles often create an additional chain of correspondence because the registered keeper may first receive a request to identify the driver. The person named in the SJPN should check precisely what allegation is charged and retain all communications from the employer, fleet provider, hire company and police.
Being in a company or hire vehicle does not automatically prevent liability, but it may be important to identification, notice service and insurance issues. The relevant driver's records, booking documents and policy arrangements may be useful evidence.
What if I was not the driver?
If the charge alleges that a person drove and that person was not the driver, the allegation should not simply be accepted for convenience. The response should reflect the actual position, and the available evidence should be preserved.
A separate section 172 allegation, concerning failure to identify a driver, has different legal issues from the underlying driving allegation. It is important to read the charge wording rather than assume that every notice concerns the same offence.
Will an SJP conviction affect my insurance?
It can. Points and motoring convictions resulting from an SJP are recorded in the same way as those from an ordinary court hearing. Insurers commonly ask about convictions and endorsements when a policy is taken out, renewed or amended.
The exact disclosure obligation depends on the policy question and wording. A driver should answer those questions accurately and should not assume that the private, paper-based nature of the SJP changes what an insurer is entitled to ask about.
Do new drivers face different consequences?
New drivers should take any proposed points especially seriously. The SJP itself operates in the same way, but a newly qualified driver's licence position can be particularly vulnerable where endorsements accumulate.
Before responding, a new driver should check the current licence record and understand the likely points for the allegation. If there is uncertainty about the effect of a guilty plea, obtaining advice before submitting the response may be appropriate.
Can I challenge an SJP conviction after it has been made?
There may be limited ways to ask a magistrates' court to reopen or set aside a decision, and an appeal may be possible in some situations. This can be relevant where the SJPN never arrived, a response was not recorded, a plea was entered by mistake or there was another material procedural issue.
The available route, evidence required and timing depend on the circumstances. A person who receives an unexpected outcome should keep the paperwork and seek prompt advice rather than assuming that non-payment or an informal complaint will undo the conviction.
Does this procedure apply in Scotland or Northern Ireland?
This guide concerns England and Wales only. The Single Justice Procedure described here is based on the magistrates' court system and the legislation applicable in those jurisdictions.
Scotland and Northern Ireland have different court structures and procedures. A notice received there should be checked against local official guidance or discussed with a lawyer qualified in the relevant jurisdiction.
