Live-Link Trials for High-Risk Defendants: No “Exceptional Circumstances” Threshold Under s.51 CJA 2003 Where Interests of Justice and Effective Participation Are Met

1. Introduction

This decision concerns the lawfulness and fairness of requiring a defendant to attend a Crown Court trial (including to give evidence) by live video link under section 51 of the Criminal Justice Act 2003, where prison authorities assessed the defendant as posing an acute and continuing risk of serious violence to staff.

The applicant (a young defendant who had significant communication and cognitive difficulties and was assisted by an intermediary) was convicted of murder after a jury trial. The trial judge directed that he participate throughout by live video link from prison due to security risks. The applicant sought leave to appeal against conviction on the basis that the live-link direction impaired effective participation and rendered the conviction unsafe. He also sought leave to appeal sentence, arguing that greater mitigation should have been reflected in the minimum term.

2. Summary of the Judgment

The Court of Appeal refused leave to appeal against both conviction and sentence.

• Conviction: The live-link direction was within the trial judge’s powers under s.51 CJA 2003, was justified by compelling and current security evidence, was reached by a careful and pragmatic evaluation of realistic alternatives, and did not prevent effective participation (supported by appropriate jury directions and use of an intermediary).
• Procedure: Although no formal written application was made in the precise form contemplated by Crim PD 3.1.4, that omission did not invalidate the process where the issue was clearly ventilated, evidence disclosed, and the defence had the opportunity to respond.
• Sentence: The minimum term (starting point 17 years under Schedule 21 as modified for youth) was not arguably manifestly excessive; the judge was entitled to find no sufficient causal connection between any disorder/impairment and the murder so as to reduce culpability further, while still giving substantial youth-related mitigation.

3. Analysis

3.1 Precedents, Guidance, and Frameworks Cited

(a) The “Management of Prisoners that present a risk of escape or violence when attending Criminal Courts” (2010 Guidance)

The Court examined the 2010 Guidance (issued by Thomas LJ) which is principally addressed to restraint/handcuff applications. It underscores:

• Security measures must not prejudice a fair trial.
• Force/restraint must be necessary, proportionate, and minimal in duration and extent.
• Applications should be supported by compelling reasons, risk assessments, and comprehensive information.
• Ordinarily, risks should be managed via secure docks and sufficient dock officers; handcuffing is “most exceptional”.

Although the Guidance is not focused on live-link directions, it formed part of the contextual security framework the trial judge considered.

(b) Criminal Practice Directions: Crim PD 3.1 (“High risk defendants at court”)

Crim PD 3.1 sets expectations for listing and management of high-risk prisoners, prioritising live link for administrative/remand appearances and requiring secure venues for in-person appearances. Crucially, where “more extensive security measures than normal are required”, HMPPS must submit a written application with “current, specific and credible evidence” and the defence must be given an opportunity to make representations.

The Court held that the absence of a formal written application in the prescribed format was not determinative on these facts, because the substance of the PD requirements was met: the security case was clear, the evidence (risk assessment plus oral evidence) was available, and defence submissions were heard.

(c) Section 51 Criminal Justice Act 2003 (as amended)

Section 51 provides the statutory power to require or permit participation by live audio/video link in eligible criminal proceedings, including Crown Court trials. The key constraints applied in this case were:

• s.51(4): must be “in the interests of justice” and parties must have the opportunity to make representations;
• s.51(5): must consider Lord Chief Justice guidance and all circumstances;
• s.51(6)(e): must consider whether the person can participate effectively.

A central clarification in the Court’s reasoning is that s.51 does not impose an “exceptional circumstances” threshold for requiring a defendant to attend the whole trial by live link, even though such a direction remains “unusual” and demands careful evaluation of evidence and realistic alternatives.

(d) Sentencing framework and authority: Sentencing Act 2020 and Schedule 21; Youth Sentencing guideline; R v ZA [2023] EWCA Crim 596

On sentence, the Court applied:

• Sentencing Act 2020, s.259 (mandatory sentence for murder by those under 18: Detention during His Majesty’s Pleasure);
• s.322 and Schedule 21 (setting and adjusting minimum terms);
• The Guideline on Sentencing Children and Young People (including the relevance of developmental immaturity and adverse childhood experiences);
• R v ZA [2023] EWCA Crim 596, relied on by the defence for the proposition that childhood trauma and related difficulties can bear materially on youth sentencing.

The Court accepted the importance of youth-specific sentencing principles, but held the trial judge was entitled, on the evidence and the trial findings, to limit the extent to which those factors reduced culpability for this particular murder.

3.2 Legal Reasoning

(A) Procedural challenge: no formal Crim PD 3.1.4 written application

The Court treated this as a compliance issue rather than a jurisdictional bar. It held that where an urgent and serious security risk arises, failure to use the correct form cannot prevent the court from considering necessary security measures, so long as fairness is maintained—especially the defence’s ability to understand and answer the evidential basis for the measures.

(B) Substantive challenge: interests of justice, proportionality, and effective participation under s.51

The Court upheld the trial judge’s approach as “careful and considered”, focusing on:

• Quality and recency of risk evidence: a detailed prison risk assessment documenting repeated threats and assaults on staff, coupled with oral evidence from the prison security lead.
• Realistic alternatives: the judge considered three broad scenarios (dock with numerous PPE-equipped officers; handcuffs/modified staffing; or live link). The defence proposal (fewer officers visible in court, with PPE officers stationed behind the dock) was rejected as unrealistic by the security evidence, and the Court of Appeal found that rejection was open to the judge.
• Fair trial protections: the applicant was represented by experienced counsel, assisted by an intermediary throughout, had opportunities for conferences/instructions, and the jury received appropriate directions, including not holding the live-link arrangement against him.
• Effective participation in fact: there were no technical barriers, the applicant could see and be seen, and the intermediary raised no concern that he could not follow proceedings.

In substance, the Court treated the decision as one of pragmatic proportionality: the trial had to proceed safely; the measures had to be the least prejudicial realistic option. On these facts, live link was found to be that option.

(C) The “exceptional circumstances” argument

The defence contended that only truly exceptional circumstances could justify requiring a defendant (against their wishes) to attend the entire trial by live link, particularly given youth and communication impairments. The Court rejected this as a legal test, holding:

• No such requirement appears in s.51.
• The correct approach is the statutory one: “interests of justice” + consideration of all circumstances, especially effective participation.
• Even so, such directions are “unusual” and require rigorous consideration of evidence and alternatives—an approach the trial judge adopted.

(D) Sentence: minimum term and youth mitigation

The Court upheld the minimum term calculation:

• Starting point: 17 years under Schedule 21 (youth equivalent where the offender took a weapon to the scene intending it be used/available and used it in the murder).
• Aggravation: notably, prior convictions involving weapons and threats with knives; the victim being a lone pedestrian; and the judge’s finding of an unprovoked attack.
• Mitigation: youth/immaturity, cognitive issues, neglect and time in care, and some allowance for mental disorder—while rejecting that disorder reduced culpability due to lack of sufficient connection to the offending.

The Court’s key sentencing point is deference to the trial judge’s evaluative assessment of the nexus between impairment and offending: without a sufficient connection, reduced culpability is not established, though the same background may still carry weight as general mitigation in youth sentencing.

3.3 Impact

• Security applications: Courts may proceed to determine urgent security measures even without strict compliance with the written-application mechanics of Crim PD 3.1.4, provided fairness is preserved and credible evidence is before the court.
• Live link as a security measure for trials: The decision strengthens the proposition that s.51 permits full-trial live-link participation where it is in the interests of justice and effective participation is maintained, without importing a free-standing “exceptional circumstances” threshold.
• Fair trial focus on outcomes not labels: The judgment indicates appellate scrutiny will concentrate on whether the defendant in fact could participate effectively (including via intermediary support), and whether jury management/directions neutralised prejudice.
• Youth murder minimum terms: The case reinforces that adverse childhood experiences and developmental immaturity are powerful considerations (consistent with R v ZA [2023] EWCA Crim 596), but they do not automatically justify movement to a lower Schedule 21 youth bracket absent an evidential basis and evaluative justification.

4. Complex Concepts Simplified

• “Interests of justice” (s.51): a broad balancing exercise including fairness, effective trial management, safety, and the integrity of proceedings.
• “Effective participation” (s.51(6)(e)): whether the defendant can understand the proceedings, communicate with lawyers, follow evidence, and (if they choose) give evidence meaningfully—here supported by an intermediary and practical arrangements.
• Crim PD 3.1.4 written application: a structured process to ensure evidence-based, proportionate security decisions and defence input; non-compliance is undesirable but may not be fatal if fairness is maintained.
• Detention during His Majesty’s Pleasure: the mandatory life-type sentence for murder committed under 18; the court sets a minimum term before the offender can be considered for release, after which detention may continue if risk requires it.
• Schedule 21 “starting point”: a statutory baseline minimum term for murder, adjusted up or down for aggravating and mitigating features; for children, the starting points differ from adults.
• “Sufficient connection” between disorder and offending: for culpability to be reduced, the impairment must have materially contributed to the offending behaviour, not merely co-exist in the offender’s background.

5. Conclusion

[2026] EWCA Crim 1002 confirms that a Crown Court may require a defendant to participate in an entire trial by live video link under s.51 CJA 2003 where it is in the interests of justice, credible evidence shows serious security risks cannot be managed realistically in court, and effective participation is safeguarded through practical steps (including intermediary support and careful jury directions). The Court also emphasised that procedural imperfections in bringing security applications will not necessarily undermine safety-driven decisions where fairness is preserved. On sentence, the Court reaffirmed youth-sentencing principles (including those reflected in R v ZA [2023] EWCA Crim 596) while upholding the trial judge’s evaluative judgment on culpability and the absence of a sufficient disorder-offence nexus.
