Acquittal on Aggravated Burglary Does Not Undermine Conviction for Conspiracy to Rob Where the Offences Have Distinct Mental Elements

1. Introduction

Thomas, R. v ([2025] EWCA Crim 1755, 18 December 2025) concerned an appeal against conviction for conspiracy to commit robbery (count 2), following a jury trial in the Crown Court at Nottingham. The appellant had pleaded guilty to dangerous driving (count 3) and was acquitted by the jury of aggravated burglary (count 1), but convicted of the conspiracy count that had been added at the start of trial.

The offending arose from a planned break-in at a domestic “cannabis factory” in Mansfield (42 Birding Street) containing 259 cannabis plants. The Crown relied on circumstantial evidence (Snapchat communications between co-accused, cell-site/ANPR material, and the appellant’s role as driver), together with the violent nature of the entry described by the occupier (Mr Nguyen).

The key appellate issue was whether the verdicts were impermissibly inconsistent (or “perverse”): did the acquittal on aggravated burglary mean the jury must have rejected the appellant’s knowledge of the violent aspects of the plan, thereby rendering the conspiracy-to-rob conviction unsafe?

2. Summary of the Judgment

The Court of Appeal (Criminal Division) (Dove LJ giving judgment) dismissed the appeal. It held that the verdicts were not inconsistent: the offences had materially different elements and the jury could rationally be sure of the agreement to use/threaten force for robbery (count 2) while not being sure the appellant knew that the intruders possessed weapons of offence (a specific requirement relevant to the aggravated burglary route on count 1).

The court further held that it was legitimate for the jury to infer, from the whole circumstantial picture (travel from London with the participants, ongoing communications, role as getaway driver, and the surrounding events), that the appellant knew the enterprise was a robbery involving force or threat of force.

3. Analysis

3.1 Precedents Cited

The judgment does not cite any prior authorities by name. The court resolved the appeal by applying orthodox principles to the specific elements of the offences, the route to verdict given to the jury, and the permissibility of drawing inferences from circumstantial evidence.

Although no case law is expressly referenced, the decision sits within the well-established appellate approach that: (i) apparent inconsistency between verdicts does not itself establish unsafety; and (ii) the correct question is whether the conviction is unsafe when the jury is assumed to have followed its directions and considered each count separately.

3.2 Legal Reasoning

(a) The “route to verdict” framed the real point of difference

Central to the court’s reasoning was the trial judge’s written route to verdict, which separated the mental elements of the two counts:

  • Count 1 (aggravated burglary): the jury had to be sure the appellant intentionally assisted/encouraged the burglary and was sure he knew the participants possessed “weapons of offence”.
  • Count 2 (conspiracy to commit robbery): the jury had to be sure that, at the time he drove onto Birding Street, the appellant had agreed with the others that they would “use force” to steal cannabis (from that address and others), intending the plan be carried out.

The Court of Appeal treated this as decisive: an acquittal on count 1 did not logically negate guilt on count 2 because the acquittal could reflect a narrow doubt about knowledge of weapons, while the conviction could reflect certainty about an agreement to use/threaten force. Put differently, “force” for robbery and “knowledge of weapons of offence” for aggravated burglary were not treated as interchangeable.

(b) No impermissible speculation: inference was available on the evidence

The appellant argued that, once the jury acquitted on aggravated burglary, any conclusion that he knew of violence was “speculative”. The Court of Appeal rejected that characterisation. It held the jury was entitled to draw legitimate inferences from the circumstances, including:

  • the coordinated travel from London to Mansfield with the co-accused;
  • the Snapchat planning between others and the broader pattern of organisation (timings, vehicles, drivers, location, crop information);
  • the appellant’s role as the driver linked to the extraction of Quarry from the scene;
  • the events following the burglary, including the escape and later dangerous driving in a vehicle shown to be stolen/false-plated.

On that material, the court held it was “well within the spectrum of legitimate inferences” that the appellant understood this was not a mere opportunistic theft but a planned operation involving force or threat of force—sufficient for the conspiracy-to-rob mental element—even if the jury was not sure he knew the intruders carried weapons.

(c) Reconciling the verdicts: distinct elements, separate evaluation

The court emphasised that the verdicts were “easily explicable” if the jury followed its directions and answered the route-to-verdict questions separately on each count. The appeal therefore failed on two linked bases:

  1. No logical inconsistency: acquittal on a weapons-knowledge requirement does not negate a force-agreement finding.
  2. No perversity/unsafety: the conspiracy conviction rested on permissible inference and adequate circumstantial evidence.

3.3 Impact

This decision is likely to be relied upon in future appeals that attempt to recast mixed verdicts as “inconsistent”:

  • Element-by-element analysis is paramount: courts will look closely at the distinct ingredients of each count, rather than assume the jury’s view on one offence mechanically controls the other.
  • Routes to verdict matter: a clearly structured route can demonstrate why verdicts are reconcilable and can insulate a conviction from “inconsistency” challenges on appeal.
  • Robbery-related force vs. weapon knowledge: the case underlines that proof of an agreement to use or threaten force does not necessarily require proof that a particular defendant knew weapons would be carried, depending on how counts are framed and directed.
  • Circumstantial inference in conspiracies: participation as a driver, association with organisers, coordinated travel, and post-event conduct may collectively support a robust inference of knowing involvement in an agreed plan, even absent direct messaging by the defendant.

4. Complex Concepts Simplified

Conspiracy to commit robbery
An agreement between two or more people to commit robbery, requiring proof that the defendant was party to the agreement and intended the plan be carried out. Robbery involves stealing with force or threat of force.
Aggravated burglary
A burglary (entering as a trespasser with intent to steal, etc.) that is “aggravated” because, at the time of the burglary, the offender has with them a weapon (or similar specified item). In this case, the route to verdict required the jury to be sure the appellant knew the others had “weapons of offence”.
Route to verdict
A structured set of questions given to the jury to help apply the legal elements to the facts. It can be critical in demonstrating that different counts involve different factual/mental findings.
Perverse / inconsistent verdicts
A complaint that the jury’s verdicts cannot rationally be reconciled. Appellate courts generally avoid second-guessing jury reasoning and focus on whether the conviction is unsafe, assuming the jury followed directions and considering whether different elements explain the outcomes.
Inference from circumstantial evidence
Juries may infer knowledge or agreement from surrounding facts (patterns of conduct, communications, coordinated movement), provided the inference is rational and not mere speculation.

5. Conclusion

Thomas, R. v confirms that mixed verdicts do not become “unsafe” merely because they arise from the same incident. Where counts have different elements—here, knowledge of weapons for the aggravated burglary route versus an agreement to use force for conspiracy to rob—a jury may rationally acquit on one and convict on the other.

The judgment also reinforces the importance of clear jury directions and the legitimacy of drawing robust inferences in conspiracy cases from coordinated travel, association, and conduct consistent with a planned criminal enterprise.
