Delay in Youth Sexual Offence Prosecutions: When CPS Process Failings Do (and Do Not) Amount to Second-Limb Abuse

1. Introduction

Okoroji v Crown Prosecution Service [2025] EWCA Crim 1869 concerned a youth defendant convicted in the Youth Court of offences of sexual activity with a child contrary to s.9 Sexual Offences Act 2003. The appellant challenged the District Judge’s refusal to stay the proceedings for abuse of process based on substantial delay between initial report, charging, and trial.

The appeal was brought by case stated under s.111 Magistrates’ Courts Act 1980, meaning the appellate court’s task was to identify an error of law, not to re-try disputed facts. The key question was whether delay in investigating and prosecuting a youth, in circumstances where the trial was accepted to be fair, nevertheless amounted to a second-limb abuse—an “affront to justice” undermining confidence in the criminal justice system.

2. Summary of the Judgment

Mrs Justice McGowan DBE dismissed the appeal. While the delay was “significant and concerning”, it was not so extreme as to require the exceptional remedy of a stay. The Youth Court judge had:

  • correctly directed himself on the two-limb abuse jurisdiction;
  • been entitled to conclude that CPS youth-offender guidance did not establish a policy breach sufficient to constitute an abuse;
  • properly treated seriousness of the alleged sexual offending and the complainant’s interest in adjudication as weighty countervailing factors;
  • addressed the practical consequences of delay through sentencing safeguards (rather than terminating the prosecution).

3. Analysis

3.1 Precedents Cited

The judgment is principally an application of established abuse-of-process doctrine to youth delay, rather than a doctrinal expansion. The cited authorities structured both the legal test and the intensity of scrutiny on appeal.

Abuse of process: the second limb and its exceptional nature

  • R v Horseferry Road Magistrates’ Court, ex parte Bennett [1994] 1 AC 42 (HL)
    Established the court’s inherent power to stay proceedings where continuing would offend justice and propriety or bring the administration of justice into disrepute, even if a fair trial is possible. This is the foundation for “second-limb” abuse.
  • R v Maxwell [2010] UKSC 48
    Used here for the proposition that “interests of justice” assessments involve evaluative judgment and legitimate differences can arise in borderline cases. This supported deference to the trial judge’s evaluative conclusion absent legal error.
  • R v Salt and anor [2015] EWCA Crim 662
    Provided the balancing framework: weigh the integrity of the justice system against the public interest in trying grave crime and the complainant’s interest in determination. The present judgment explicitly adopts this structure when rejecting the stay.
  • D.P.P v Humphrys [1977] A.C.1, HL
    Cited in the Youth Court ruling to emphasise that stopping a prosecution is exceptional and to be used “most sparingly”.

Failure to follow prosecutorial policy as a route to abuse / public law control

  • R v Adaway [2004] EWCA Crim 2831
    Recognised that prosecutorial failure (there, evidential assessment) can, in principle, ground abuse arguments. It was treated as a limited authority, not establishing any automatic stay for process shortcomings.
  • R v Chief Constable of Kent and Another ex parte L, R v DPP ex parte B [1991] 93 Cr App R 416
    Central to the CPS youth guidance: decisions may be susceptible to challenge if taken without sufficient inquiry into a youth’s circumstances and general character. In this appeal, it informed what “policy compliance” might entail, but did not convert delay into abuse absent the high “affront to justice” threshold.
  • Jones v DPP [2011] EWC 50 (Admin)
    Cited for the proposition that even where a prosecution is brought contrary to a clear policy, the court intervenes only if continuing would bring the administration of justice into disrepute. This reinforced the high bar.
  • R (on the application of E, S and R v DPP [2011] EWHC 1465 (Admin)
    Referred to through the CPS guidance: failure properly to apply youth guidance can lead to quashing in judicial review. The judgment distinguishes that public law route from the narrower evidential and procedural setting of a summary court abuse application and a s.111 appeal.

Procedure, burden, and powers in the magistrates’/youth court context

  • R v Derby Crown Court Ex P Brooks 80 CR. App. R.164
    Cited for fairness “to both the defendant and the prosecution”.
  • R v Telford Justices Ex P Badham, 93 CR. App. R.171
    Cited for burden on the defence (civil standard) in abuse applications.
  • R v S (SP) [2006] 2 Cr. App. R. 23
    Cited for abuse-by-delay being an evaluative judicial assessment.
  • Mansfield v D.P.P [2021] EWHC 293 (Admin)
    Cited in the Youth Court ruling for the proposition that summary courts have power to stay in both first- and second-limb cases (relevant to jurisdictional competence).

Delay as a sentencing consideration (rather than a stay)

  • R v Ghafoor [2002] EWCA Crim 1857 and s.29(1) of the Children and Young Persons Act 1963
    Relied upon by the Youth Court judge as “protection” at sentence: where there has been delay and significant passage of time, sentencing can reflect that (especially for young defendants), mitigating the injustice without extinguishing the prosecution.

3.2 Legal Reasoning

The judgment proceeds on four linked propositions.

(a) The appellate lens is narrow: s.111 case stated requires an error of law

The court emphasised that a case stated appeal is not an invitation to re-evaluate the factual balance of delay, seriousness, and policy compliance. The appellant had to show the Youth Court’s conclusion was wrong in law, not merely arguable on the merits.

(b) The abuse jurisdiction is exceptional; second-limb abuse demands a high threshold

Because a fair trial was conceded, the case turned entirely on second-limb abuse: whether the delay and conduct of the investigation/prosecution made it unfair to try the appellant in the broader sense of harming justice system integrity. The court treated Bennett and Salt as requiring a balance: integrity concerns versus the public interest in adjudicating serious sexual allegations and the complainant’s interest in having the allegations determined.

(c) CPS youth guidance creates real duties, but non-compliance does not automatically equal abuse

The CPS guidance on children as suspects/defendants stresses expedition and the need to obtain background material and consider diversion. The judgment accepts a practical tension: extra safeguarding and contextual inquiry can itself generate delay. Here, the court considered that the investigative steps (school engagement, third-party material, CAMHS/social services interactions) were consistent with policy-driven thoroughness, not demonstrative of disregard.

Importantly, the Youth Court judge refused to infer policy breach from the non-disclosure (on a voluntary basis) of internal CPS charge reviews and action plans—particularly where the defence had not specifically sought them in the defence case statement or via a disclosure application, and where legal professional privilege and disclosure rules might have been in issue. The appellate court endorsed that approach as legally sound.

(d) Youth-specific prejudice from delay is real, but was addressed without the drastic remedy of a stay

The court accepted that “educational and developmental landmarks” had passed and that youth offenders may struggle to relate sentence to conduct after long delay (a core rationale of the CPS youth guidance). However, it treated those consequences as capable of being reflected in sentence, and not, on these facts, sufficient to tip the case into “affront to justice” territory.

3.3 Impact

Although fact-specific, the decision offers practical guidance for delay-based second-limb abuse arguments in youth cases:

  • “Significant and concerning” delay is not enough: where trial fairness is intact and the allegations are grave, the court will be slow to halt proceedings absent truly extreme, system-shocking delay or misconduct.
  • Policy-breach arguments must be evidenced and procedurally grounded: a defendant should not expect a court to infer CPS non-compliance merely from the existence of delay or the absence of voluntary disclosure of internal reviews, especially where disclosure avenues were not pursued.
  • Balancing under Salt is central: seriousness of sexual offences and the complainant’s right to determination remain powerful factors against a stay.
  • Sentencing is the orthodox corrective for some forms of delay in youth matters, where delay has diluted the connection between offence and punishment.

4. Complex Concepts Simplified

  • Case stated (s.111 Magistrates’ Courts Act 1980): an appeal route focused on legal error. The appellate court will not simply substitute its own assessment of the facts or re-run the balancing exercise unless the lower court applied the wrong legal test or misdirected itself.
  • Abuse of process—two limbs:
    • First limb: the defendant cannot receive a fair trial (e.g., evidence lost, inability to test key issues).
    • Second limb: even if the trial can be fair, the prosecution should be stopped to protect justice system integrity (the “affront to justice” category).
  • “Affront to justice”: a very high standard. It asks whether continuing would offend justice and propriety or damage public confidence in the courts.
  • CPS youth guidance: policy requiring both expedition and fuller inquiry into a youth’s circumstances, with attention to diversion where appropriate. It informs good decision-making, but does not itself mandate a stay for every breach or delay.
  • Disclosure and privilege: internal prosecutorial reviews may engage legal professional privilege or fall outside standard disclosure unless they meet statutory tests and are properly sought through procedure.

5. Conclusion

Okoroji v Crown Prosecution Service [2025] EWCA Crim 1869 confirms that, in youth prosecutions, delay—however regrettable—will rarely justify a second-limb abuse stay where the trial remains fair and the allegations are serious. The court endorsed a structured Salt-style balance: public confidence in justice must be protected, but so too must the strong public interest in adjudicating grave sexual allegations and securing a determination for the complainant. Where delay has weakened the connection between offending and punishment for a young defendant, the judgment underscores sentencing as the primary mechanism to reflect that unfairness, not the termination of proceedings.
