Staying Proceedings as Abuse of Process Where Police Fail to Obtain CCTV Central to Credibility (and a Fair Trial Cannot Be Cured by Directions)

1. Introduction

R v HGF [2026] EWCA Crim 570 is a prosecution appeal under section 58 of the Criminal Justice Act 2003 against a Crown Court ruling staying an indictment for sexual assault contrary to section 3 of the Sexual Offences Act 2003. The trial had not begun and no jury had been sworn. The judge stayed the proceedings as an abuse of process on the first limb (no fair trial possible) because the police failed to obtain hotel CCTV of public areas which the respondent said would support his account and undermine the complainant’s credibility.

The Court of Appeal (Criminal Division) (The Lady Chief Justice, Garnham J and Soole J) dismissed the appeal, holding that this was one of the rare cases where missing investigative material was so central to credibility that the resulting prejudice could not be cured without inviting impermissible speculation by the jury.

Key participants and context

  • The respondent: “HGF” (anonymised).
  • The complainant: “C” (anonymised).
  • Trial judge: Her Honour Judge Thompson (Crown Court at Harrow).
  • Appeal court: Court of Appeal (Criminal Division).

Core issue

Whether proceedings should be stayed for abuse of process because police failed to obtain CCTV from communal hotel areas which might have provided the only independent material capable of materially testing the complainant’s credibility in a “word against word” allegation said to have occurred in a private room.

2. Summary of the Judgment

  • The Court reiterated that a stay for abuse of process is a measure of last resort, but confirmed the availability of a stay where missing material makes a fair trial impossible.
  • The Court accepted the judge was entitled to treat the missing CCTV as central, not marginal: it was the “best independent evidence” of prior interactions in circumstances where there would be no useful forensics, no independent witnesses, and no CCTV of the bedroom/corridor.
  • The Court rejected the prosecution’s proposed “curative” approach (directions allowing inference that the respondent believed CCTV would support him), because it would still require the jury to speculate about what the CCTV would have shown.
  • Applying the appellate standard in section 67 of the Criminal Justice Act 2003, the Court was not satisfied the ruling was wrong in law, involved error of law/principle, or was unreasonable.
  • The Court therefore dismissed the appeal and did not need to address the second limb (public confidence/propriety).

3. Analysis

3.1 Precedents cited and their influence

R v Ng and O'Reilly [2024] EWCA Crim 493

The Court used R v Ng and O'Reilly to restate foundational principles: staying proceedings is exceptional, exercised with care and restraint, and is the exception not the rule. It also reiterated the two distinct “limbs”: (1) fair trial impossible; (2) affront to justice/propriety/public confidence. This framing mattered because the prosecution argued the trial judge treated stay too readily; the Court of Appeal disagreed, viewing the case as falling within the “rare” category.

R v Feltham Magistrates' Court, ex parte Ebrahim [2001] EWHC (Admin) 130

Ebrahim provided a structured approach to the first limb (fair trial), emphasising: (i) a stay arises only where it is clear a fair trial cannot occur (with Article 6 ECHR in view); (ii) fairness is not one-sided (the guilty should be convicted); (iii) the trial process usually cures complaints—cases where unfairness is inevitable are “few and far between”; (iv) missing material often creates “holes” that the defence can exploit; if there is sufficient credible evidence apart from the missing material to justify a safe conviction, a trial should proceed.

The prosecution relied on this “holes in the case” logic; the Court held the present case fell outside that paradigm because the missing CCTV was not merely absent support for the prosecution case, but potentially critical material for assessing credibility.

R v Dobson [2001] EWCA Crim 1606

Dobson distilled the first-limb inquiry into three questions: (1) what was the police duty; (2) did the police fail; (3) did that failure cause serious prejudice such that no fair trial could be held? The trial judge explicitly relied on Dobson and the Court of Appeal accepted she applied the right framework. Notably, the Court treated the police failure as a “serious dereliction of duty”, reinforcing the second step of the Dobson analysis.

Ali v Crown Prosecution Service [2007] EWCA Crim 691

Ali provided the key doctrinal “bridge” enabling the Court to distinguish Ebrahim. The Court in Ali explained that the “credible evidence apart from missing material” approach works where the missing evidence is separable; it is harder where the missing evidence is itself part of the material by which the jury assesses credibility.

The Court of Appeal treated the present case as Ali-type: the missing CCTV was “important material by which C’s credibility could be assessed”. That meant the central question was not the remaining strength of the prosecution evidence, but the defence being deprived of its primary means of challenging it.

Blackstone's Criminal Practice 2026

Although not a binding authority, Blackstone’s is a leading practitioner text. Its citation supported the conclusion that the trial judge approached “abuse of process” by reference to established legal tests and the exceptional nature of a stay.

3.2 Legal reasoning

(a) The statutory appeal framework: why deference mattered

The appeal fell under section 58 (prosecution appeals of certain rulings) and the Court applied section 67 (limits on reversal): it could intervene only if the ruling was wrong in law, involved an error of law or principle, or was unreasonable. This statutory standard is important: even if an appellate court might have reached a different view, it may not substitute its view unless the stringent threshold is met.

(b) Police duty and the character of the failure

The Court proceeded on the basis (recorded as accepted below) that the police had a duty to obtain the hotel lobby/ reception CCTV and failed to do so. The failure was aggravated by the respondent raising CCTV immediately (both on the initial call and in interview) and by an investigating officer’s express assurance that police would retrieve and review it.

The Court’s reasoning signals that where police:

  • are promptly alerted to specific, time-limited third-party digital material (like CCTV);
  • recognise its potential value (including by making explicit assurances); and
  • do not take reasonable steps before it is overwritten,

the failure is more readily characterised as a serious investigative default capable of generating trial unfairness.

(c) Why the CCTV mattered despite the allegation being in a bedroom

A central prosecution submission was that the “real issue” was what happened in the bedroom and there was no CCTV there, so lobby CCTV was peripheral. The Court rejected that characterisation because:

  • the case turned on credibility, with no realistic prospect of independent corroboration of the bedroom events;
  • the parties spent substantial time together beforehand, making prior interaction potentially significant;
  • the lobby CCTV was the “best independent evidence” of their behaviours shortly before the allegation;
  • the defence case (as raised from the outset) was that CCTV would support an account inconsistent with the complainant’s narrative and could materially affect credibility assessment.

The Court therefore treated the CCTV as potentially decisive in evaluating credibility in a “word against word” scenario, aligning with the Ali analysis.

(d) Remedy and jury directions: the problem of impermissible speculation

The Court held no trial mechanism could cure the prejudice without inviting speculation. The prosecution’s best proposal—a direction that the jury could infer the respondent believed the CCTV supported him—failed because the probative value of belief depended on whether the belief was correct, which could not be assessed without speculating about missing footage.

The Court’s reasoning is significant: it identifies a limit to the usual “the trial can deal with it” approach where the missing material is central to credibility and any attempt to “balance” the absence through directions risks turning the jury’s task into conjecture.

3.3 Impact

(a) For abuse of process applications involving missing digital evidence

The judgment reinforces that, exceptionally, a stay may be appropriate where missing third-party digital material (especially CCTV) is the primary independent means of testing credibility and its absence cannot be managed fairly by conventional trial safeguards.

(b) Clarifying the Ebrahim–Ali distinction

The decision provides a practical guide:

  • Ebrahim-type cases: missing evidence creates “holes” but the jury can still assess sufficient credible evidence; the defence can exploit the gap; trial usually proceeds.
  • Ali-type cases: missing evidence is itself integral to assessing the credibility of the evidence the jury must believe; the “safe conviction without it” logic is less apt; a fair trial may be impossible.

(c) For policing and charging decisions

The judgment underlines the operational importance of prompt evidence preservation where a suspect specifically identifies time-limited CCTV. Failures may not merely affect weight; they can terminate proceedings entirely. It also implicitly encourages early investigative focus on third-party material in credibility-centric offences, where forensic corroboration is unlikely.

(d) For prosecutors

Prosecutors may need to scrutinise early whether missing evidence creates an Ali-type credibility deficit and whether any proposed directions would, in practice, invite impermissible speculation. The Court’s treatment suggests that “belief-based” inferences will often be insufficient where the underlying material is unavailable.

4. Complex Concepts Simplified

  • Abuse of process (stay): a court order stopping a prosecution because continuing would be improper. It is exceptional.
  • Two limbs of abuse:
    • Limb 1: a fair trial is not possible (linked to Article 6 ECHR).
    • Limb 2: trying the defendant would offend justice/propriety or undermine public confidence.
  • “Rolled-up” hearing: the court decides permission to appeal and, if granted, hears the appeal immediately.
  • “Holes in the evidence”: missing evidence may simply weaken the prosecution case; often the remedy is for the defence to highlight the gap at trial rather than stopping the case.
  • Impermissible speculation: jurors must not guess what missing evidence would have shown; directions must avoid inviting such guesswork.
  • Section 67 CJA 2003 appellate restraint: the Court of Appeal cannot overturn a prosecution-appeal ruling just because it would have decided differently; it must find legal error or unreasonableness.

5. Conclusion

R v HGF [2026] EWCA Crim 570 confirms that while staying proceedings is a last resort, it is justified where police fail to secure CCTV that is central to assessing credibility in a case lacking other independent corroboration, and where no direction can cure the resulting unfairness without inviting speculation. The Court’s reliance on the Ali credibility-focused approach (rather than the Ebrahim “holes in the case” approach) is the judgment’s main doctrinal contribution and a warning that lost third-party digital evidence can be dispositive of trial fairness.
