Neurodiversity (ADHD), Intermediary Measures, and the “Unsafe Conviction” Test: No Appeal Without Demonstrable Trial Unfairness

1. Introduction

This application concerned whether Mr Ahmad’s conviction for affray was arguably unsafe in light of complaints tied to his ADHD and related alleged disadvantages in trial participation. The case arose from a violent confrontation at First Choice Motors (Uxbridge Road) on 2 April 2022 involving Mr Ahmad and three co-accused. The evidence included mobile phone footage from an independent bystander and CCTV capturing the incident.

The procedural history is significant. Mr Ahmad’s original representatives withdrew mid-trial in March 2024 due to an irretrievable breakdown; the trial judge then severed his case, and the co-accused trial continued to verdicts. Mr Ahmad was tried separately in December 2024 and convicted. He sought leave to appeal against conviction after refusal by the Single Judge.

The core trial issue was self-defence: whether Mr Ahmad joined and escalated violence when he did not need to, and whether his punches (including striking Grover when on the floor) went beyond lawful self-defence or defence of another (the woman visible in footage).

2. Summary of the Judgment

The Court of Appeal refused leave to appeal. It held the conviction was not even arguably unsafe. In particular:

• The impact of ADHD on participation was assessed in advance via specialist intermediary assessment and liaison/diversion input, and measures were implemented.
• Mr Ahmad had “unusually” extensive intermediary assistance throughout trial.
• The trial judge’s directions (including about intermediary use and ADHD-related memory/anxiety) were not criticised and disclosed no error.
• Mr Ahmad gave cogent evidence, was able to deal with cross-examination, and his self-defence/defence-of-another case was presented to the jury.
• Complaints about lawyers (including failure to obtain an ADHD doctor) did not show professional default causing unfairness.
• Given the centrality of CCTV/mobile phone footage, there was no demonstrated disadvantage producing an unsafe outcome.

3. Analysis

3.1 Precedents Cited

The absence of named precedents is itself instructive: the court treated the issues as turning on the factual record—what measures were actually in place, what the summing-up actually did, and whether any asserted neurodiversity-related disadvantage materialised into concrete unfairness affecting safety of conviction.

3.2 Legal Reasoning

The court’s reasoning proceeds in a structured way, moving from allegation to evidential reality:

• Alleged failure to obtain an ADHD specialist: The court accepted ADHD was relevant to participation and potentially to how the jury assessed evidence (e.g., memory/anxiety), but found that the need for support was identified and addressed through intermediary assessment and liaison/diversion recommendations. On the record, additional medical evidence was not shown to be necessary to ensure a fair trial.
• Intermediary ineffectiveness: The complaint was that the intermediary could not “speak on his behalf.” The court implicitly treated the intermediary’s role as facilitative (communication support), not substitutionary advocacy. It noted the intermediary was present throughout and the judge gave an “uncontroversial” direction about use of an intermediary.
• Fitness to participate demonstrated by performance: A key factual anchor was that Mr Ahmad gave “cogent” evidence, could answer questions in cross-examination, and his account was fully put before the jury. This directly undercut claims that ADHD rendered proceedings unfair in practice.
• Complaints about representation assessed against the record: After waiver of privilege, the court reviewed detailed solicitor/counsel responses. It accepted there were significant difficulties in taking instructions (including behaviour consistent with ADHD), but found no basis to conclude professional obligations were breached or that preparation/presentation fell below what fairness required.
• The missing witness and case management decisions: The Applicant focused on a woman (Choudery’s daughter) said to support his defence-of-another account. The court recorded counsel’s attempts (adjournment; remote evidence; statement admission) were refused, and treated these as case management matters for the trial judge. Importantly, the Applicant did not seek to impugn those judicial decisions on appeal.
• Centrality of objective video evidence: The court emphasised that the “essential” evidence was CCTV and mobile footage capturing the incident. This reduced the plausibility that participation difficulties—if any—could have produced an unsafe verdict, because the jury’s assessment was largely anchored in objective contemporaneous recordings rather than solely in nuanced testimonial credibility.

Taken together, the court required a clear link between (i) ADHD/neurodiversity and (ii) a concrete procedural or forensic disadvantage that made the conviction arguably unsafe. It found that link missing.

3.3 Impact

Although the judgment does not announce a new doctrinal test, it provides a practical appellate message for future cases involving neurodiversity and fair trial complaints:

• Fairness is assessed operationally: Courts will scrutinise what adjustments were actually made (intermediary support, tailored recommendations, judicial directions) and whether the defendant could participate effectively in fact.
• ADHD does not automatically translate to unsafe conviction: Even where ADHD creates genuine communication challenges, an appeal will not progress absent demonstrated prejudice—i.e., a material effect on participation, evidence, or the jury’s ability to evaluate the defence.
• Objective evidence can be outcome-determinative in “safety” analysis: Where video footage comprehensively captures the incident, appellate courts may be less receptive to claims that additional expert input or alternative presentation would likely have altered the result.
• Intermediary support is framed as assistance, not proxy advocacy: Complaints premised on an intermediary not “speaking on behalf” of a defendant are unlikely to succeed unless tied to a failure of communication facilitation that demonstrably impaired trial fairness.

4. Complex Concepts Simplified

• Affray: A public order offence involving the use or threat of unlawful violence such that a person of reasonable firmness would fear for their safety. In this case, the jury assessed whether Mr Ahmad’s punches formed part of unlawful violence not justified by self-defence.
• Self-defence / defence of another: A person may use reasonable force to defend themselves or someone else. The key question is whether force was necessary and proportionate in the circumstances as the defendant believed them to be.
• Severance: Splitting defendants’ trials. Here severance occurred after the Applicant’s representatives withdrew, allowing the co-accused trial to continue separately.
• Intermediary: A specialist who assists communication (understanding questions and expressing answers). The intermediary does not act as a legal representative; they help ensure the defendant can effectively participate.
• “Unsafe conviction” (appellate safety): The appellate court asks whether the conviction can safely stand. Complaints about procedure or representation must typically show a real risk that the verdict is unreliable or that the trial was unfair in a way that affects safety.
• Waiver of privilege: When a defendant allows communications with their lawyers to be disclosed so the court can evaluate complaints about representation.

5. Conclusion

Ahmad, R. v illustrates that neurodiversity-based appeals in criminal proceedings are intensely fact-sensitive: the focus is not on diagnosis alone, but on whether participation difficulties were identified, accommodated, and—crucially—whether any remaining disadvantage rendered the conviction arguably unsafe. Here, intermediary support throughout trial, careful pre-trial assessments, an adequate summing-up addressing ADHD-related issues, and the presence of strong objective video evidence led the Court of Appeal to refuse leave to appeal.
