Delayed Prosecutions: Distinct Roles for Mitigation and Sentencing Totality

1. Introduction

This judgment examines how sentencing courts should respond when an unexplained charging delay separates an offence from its eventual punishment, particularly where the offender has served, or is serving, another sentence in the meantime. It distinguishes two related but legally separate questions: whether delay and its consequences justify mitigation, and whether the principle of totality requires an adjustment to reflect an earlier sentence.

Two applicants challenged concurrent sentences of 30 months’ imprisonment for Class A drug offences committed in September 2022 but not charged until September 2025. The prosecution accepted that the delay was unreasonable and lacked any good explanation. Nevertheless, the Court of Appeal reached different outcomes: the first applicant was refused permission to appeal, while the second applicant’s sentences were reduced to concurrent terms of 18 months.

The decision principally applies and clarifies established sentencing principles rather than creating an automatic entitlement to a discount for delayed prosecution. Its significance lies in showing why the same investigative delay may have materially different sentencing consequences for different offenders.

2. Background and Sentencing History

The offences

Following a police pursuit and the occupants’ transfer between vehicles, both applicants were arrested on 4 September 2022. A bag belonging to the second applicant contained 124 grams of cocaine at 83 per cent purity, valued at £12,400, together with cash. Messages on his telephone demonstrated involvement in street-level diamorphine supply. The first applicant carried a separate bag containing 84 wraps of crack cocaine and 30 wraps of diamorphine.

Both applicants were released under investigation. Postal requisitions were eventually issued on 25 September 2025, more than three years after their arrests. No explanation was provided for that interval.

In January 2026, the first applicant pleaded guilty to possessing cocaine and diamorphine with intent to supply. The second applicant pleaded guilty to possession of cocaine with intent to supply and being concerned in the supply of diamorphine.

The intervening sentences

• The first applicant: He was 22 when the drug offences occurred and had a previous conviction for cocaine possession. He was also on bail for an earlier dangerous-driving offence. A suspended sentence subsequently imposed for that offence was activated in part in April 2023 after breaches, resulting in seven months’ imprisonment. He later received a concurrent sentence for driving while disqualified.
• The second applicant: He was 18 and of good character when the September 2022 offences occurred. He subsequently committed further offences, including drug offences in December 2022 and a cocaine-supply conspiracy in December 2023. In February 2025, he received an aggregate sentence of five years and ten months’ imprisonment for those later matters. The sentencing judge apparently did not know about the outstanding September 2022 allegations.

The sentences under challenge

In July 2026, the sentencing judge classified both applicants’ offending as category 3, significant role under the applicable drug guidelines. That classification, carrying a starting point of four and a half years, was accepted on appeal.

The judge applied a 25 per cent guilty-plea reduction, rounding the resulting sentence down in the applicants’ favour to 40 months. He then deducted ten months for personal mitigation and significant delay, producing concurrent sentences of 30 months for each applicant’s offences.

3. Issues and Decision

The applications raised three principal questions:

1. Had the sentencing judge sufficiently reflected the unreasonable delay and the applicants’ personal circumstances?
2. Should imprisonment already served, or still being served, have led to a further reduction under the totality principle?
3. Were the resulting sentences manifestly excessive or wrong in principle?

The distinction was not that the delay was unreasonable for only one applicant. It was unreasonable for both. The decisive difference was the effect of their respective sentencing histories, particularly the relationship between the second applicant’s earliest offences and his later drug offending.

4. Precedents Cited and Their Influence

R v Barrett [2025] EWCA Crim 840

At paragraph 15, the court relied on this authority to explain the detrimental effects contemplated by the General Guideline: Overarching Principles. Examples include genuine psychological or physical harm caused by delay, or an offender having to put life on hold while awaiting a prosecution decision.

The importance of this authority is its focus on consequences rather than elapsed time alone. Establishing an unreasonable delay does not, without more, determine the size or necessity of a sentencing reduction. The court must examine what the delay actually did to the offender.

R v Timpson [2023] EWCA Crim 453

This decision addressed substantial intervals between the conclusion of an investigation and the decision to charge. It recognised that such delay will often produce some reduction in sentence, particularly following a guilty plea, but observed that a reduction as large as 25 per cent would be most unlikely, especially for serious offending.

The Court of Appeal used that observation when assessing the generosity of the first applicant’s sentence. His ten-month allowance for delay and other mitigation amounted to 25 per cent of the 40-month figure reached after guilty-plea credit.

However, the judgment does not establish a binding 25 per cent ceiling. Nor was the ten-month allowance exclusively attributable to delay: it also reflected personal mitigation. The authority supplies guidance on proportionality, not a fixed tariff.

R v Wilson (Billy-Joe) [2026] EWCA Crim 427

This authority explains why the significance of delay is not confined to harm of the kind identified in R v Barrett [2025] EWCA Crim 840. There, a lengthy interval had enabled the offender to demonstrate sustained rehabilitation, including positive steps to address personal difficulties and evidence of lasting stability.

Although the offender had not suffered the conventional detrimental effects of delay, those positive developments provided substantial mitigation. The decision therefore distinguishes between compensation for harm caused by delay and recognition of genuine rehabilitation demonstrated during it.

The present judgment adopts that distinction. A court should examine meaningful changes in an offender’s circumstances, rather than ask only whether waiting for prosecution caused distress. Nevertheless, merely having spent years awaiting proceedings does not establish rehabilitation, and the judgment makes no finding that the first applicant’s circumstances required an additional reduction comparable to that justified by the evidence in this earlier case.

R v Green (Michael) [2019] EWCA Crim 196

This was the central authority on sentencing an offender who has already received a sentence for other offences. It identifies a non-exhaustive range of relevant considerations, including:

• how recently the earlier sentence was imposed;
• the similarity between the earlier and current offences;
• whether their periods of commission overlapped; and
• whether the combined punishment would offend totality if the sentences had been imposed together consecutively.

The court must first determine the appropriate sentence for the current offences, including totality between those offences themselves. It then has discretion to make a further allowance for the earlier sentence.

That approach, reflected in the Totality Guideline, does not require a court to invent a single historical aggregate sentence and mechanically subtract the punishment already imposed. It calls for a contextual assessment. This distinction supported the refusal of an additional allowance for the first applicant and the grant of a substantial allowance for the second.

5. Legal Reasoning

A. Delay and totality perform different functions

The General Guideline permits a reduction where unreasonable delay since apprehension, not attributable to the offender, has had a detrimental effect. The authorities also recognise that sustained rehabilitation during a lengthy interval can provide significant mitigation.

Totality addresses a different concern: whether the overall punishment for multiple offences remains just and proportionate. Its relevance does not depend on proof of psychological harm or rehabilitation. Conversely, a delay allowance does not necessarily resolve the distinct question of how a new sentence should relate to an earlier one.

This separation explains the second applicant’s successful appeal. The sentencing judge had already allowed for delay, but that did not adequately answer the totality issue created by the substantial February 2025 sentence.

B. Mitigation must precede guilty-plea credit

The Court of Appeal identified an error in the order of calculation. Reductions for mitigation, including delay, should have been applied before the reduction for guilty pleas.

Using the sentencing judge’s figures, the correct sequence would have been:

1. Start at 54 months.
2. Deduct ten months for mitigation, leaving 44 months.
3. Apply the 25 per cent guilty-plea reduction, producing 33 months.

Instead, the judge reduced and rounded the starting point to 40 months before deducting ten months, producing 30 months. The error therefore favoured the applicants. It did not justify increasing their sentences in these proceedings, but it reinforced the conclusion that the first applicant’s sentence was not manifestly excessive.

C. Why the first applicant received no further reduction

The court regarded the 30-month sentence as already generous. The guideline starting point was correct; the guilty-plea allowance was favourable; and the judge had made a substantial additional deduction for mitigation and delay. The judge had also refrained from treating the commission of the offences while on bail as an aggravating factor.

The earlier imprisonment did not compel another reduction. It resulted from a second breach of a suspended sentence imposed after the drug offending, and the applicant had already benefited because the suspended sentence was activated only in part. The court therefore declined to treat that imprisonment as requiring a further allowance against the present sentence.

The court also considered a community order. Although the relevant general guidance permits a community order instead of a short or moderate custodial sentence in an appropriate case, that possibility did not make immediate imprisonment wrong here. Neither the applicant’s rehabilitation submissions nor the delay required a non-custodial disposal.

D. Why totality required a reduction for the second applicant

The second applicant’s circumstances were materially different. The current offences were the first in a sequence of offences for which he subsequently received a substantial custodial sentence. At the time of these earliest offences, he was only 18 and of good character—features that would have supplied significant mitigation had he been sentenced promptly.

The court considered that all the matters could and should have been sentenced together. The prosecution had not explained either the failure to charge sooner or the failure to inform the February 2025 sentencing judge about the outstanding allegations.

Had sentencing been coordinated, the court considered two realistic possibilities:

• a concurrent sentence for the earliest offences, with an increased sentence for the December 2022 drug offending to reflect the additional criminality; or
• a consecutive sentence shorter than the 30 months eventually imposed.

Neither possibility meant that the earliest offences should attract no additional punishment. The court expressly recognised that awareness of the later offending having occurred while the applicant was under investigation would probably have increased the sentences imposed in February 2025.

Balancing those considerations, the court substituted concurrent terms of 18 months for the present offences. Those terms were concurrent with each other; the judgment should not be read as directing that they run concurrently with the earlier February 2025 sentence.

6. Impact and Practical Significance

Individualised assessment remains essential

The contrasting outcomes demonstrate why co-defendants affected by the same delay need not receive identical relief. Age, character at the time of offending, subsequent conduct, rehabilitation, and the relationship between separate sentences all matter.

Delay should be evidenced, not merely asserted

Future mitigation should identify the concrete consequences of delay. Evidence of harm, disrupted plans or sustained rehabilitation will assist the court more than reliance on the passage of time alone. At the same time, the rehabilitation authorities prevent the inquiry from becoming confined to demonstrable suffering.

Earlier sentences require a separate totality analysis

A generous reduction for delay does not remove the need to consider whether another sentence makes the overall punishment disproportionate. Equally, imprisonment already served does not operate as a general credit against later punishment for unrelated offending.

Prosecutorial coordination matters

The judgment highlights the sentencing consequences of failing to identify related outstanding allegations before another sentencing hearing. Such failures can deprive a court of the opportunity to assess the offender’s criminality as a whole. The remedy here was a proportionate sentencing adjustment, not the dismissal of charges or the invalidation of convictions.

The decision’s limits

The judgment establishes no automatic discount for unreasonable delay, no fixed percentage allowance, and no general entitlement to concurrent sentences whenever offences could have been dealt with together. It reinforces a structured but discretionary approach under existing guidelines and authorities.

7. Complex Concepts Simplified

Totality

The requirement that punishment for multiple offences, viewed overall, should fairly reflect the offender’s criminality without becoming disproportionate.

Concurrent and consecutive sentences

Concurrent sentences run together. Consecutive sentences run one after another. Neither arrangement removes the need to assess the fairness of the overall punishment.

Released under investigation

A person has been released while the authorities continue investigating or deciding whether to prosecute. Release is not a determination that proceedings have ended.

Mitigation and guilty-plea credit

Mitigation reduces sentence because of relevant circumstances of the offence or offender. Guilty-plea credit is a separate reduction applied afterwards.

Manifestly excessive or wrong in principle

The appellate court asks whether a sentence falls outside a proper sentencing assessment or rests on a legal error, rather than simply whether another judge might have selected a different sentence.

Leave to appeal

Permission to pursue an appeal. The first applicant did not obtain permission; the second obtained permission and succeeded in securing reduced sentences.

8. Conclusion

The judgment’s central lesson is that delay mitigation and sentencing totality must be considered separately, even when they arise from the same procedural history. Unreasonable delay is not an automatic entitlement to a particular reduction, and earlier imprisonment is not a transferable sentencing credit.

For the first applicant, the existing allowance was sufficient. For the second, the failure to coordinate related prosecutions left an overall sentencing problem requiring further adjustment. The decision therefore reinforces proportionate, individualised sentencing while emphasising the practical importance of timely charging and informed sentencing hearings.
