Background
Erron Troy Hogg was convicted after a Provincial Court trial of aggravated assault arising from an attack on the victim at an apartment the accused leased for his girlfriend, A.S.R. The victim was alone in the apartment when Hogg entered, threatened to kill him, and viciously attacked him, leaving the victim with serious injuries to both sides of his head, including facial fracturing, significant bruising and swelling, and bleeding from the right ear.
On appeal, Hogg raised two grounds: first, that the trial judge erred or breached procedural fairness by finding that he had colluded with A.S.R., a defence witness, and that this tainted her credibility assessment; and second, that the trial judge misapprehended or failed to give legal effect to material evidence relevant to his claim of self-defence. Hogg also brought a motion to admit fresh evidence in the form of an affidavit and photograph from a friend who claimed to have observed his injuries three days after the incident.
Both Hogg and A.S.R. testified that they had spoken by telephone immediately after the assault. The trial judge found their accounts of that conversation and the description of Hogg’s injuries to be so identical as to be unbelievable, and specifically noted that their testimony reproduced particular details in “the exact same words and phrasing.” These findings formed part of a broader credibility assessment that also included internal inconsistencies in Hogg’s evidence, contradictions with surveillance footage, and incompatibility with the medical and police evidence.
The Court’s Holding
The Court of Appeal, per leMaistre JA, denied the motion to admit fresh evidence and dismissed the appeal. On the fresh evidence motion, the court found that the proposed evidence failed the Palmer test (see Palmer v The Queen, 1979 CanLII 8 (SCC)) because it could not reasonably be expected to have affected the result. Critically, the friend’s description of Hogg’s injuries and the photograph she took were inconsistent with Hogg’s own testimony about the nature and extent of those injuries, undermining the probative value of the proposed evidence.
On the collusion ground, the court held that the trial judge’s finding was neither speculative nor procedurally unfair. The finding was grounded in the striking, detailed, and selective alignment between Hogg’s and A.S.R.’s accounts — particularly contrasted with A.S.R.’s vague and minimal recollection of her separate conversation with the victim. The court confirmed that collusion is simply one factor within a broader credibility analysis: intentional collusion may undermine credibility while unintentional collusion may affect reliability, and a trial judge’s assessment of the degree of risk attracts significant appellate deference.
On self-defence, the court held that the trial judge committed no reviewable error. She had considered the contextual evidence — including prior animosity between the parties — but found that the nature, severity, and distribution of the victim’s injuries were inconsistent with a brief defensive struggle and more consistent with the victim’s account of the assault. This reflected a permissible weighing of the evidence rather than a misapprehension of it. The trial judge had also properly applied the W(D) framework (R v W(D), [1991] 1 SCR 742).
Key Takeaways
- Fresh evidence must satisfy the Palmer test; evidence that is internally inconsistent with the very witness it is meant to support will not meet the requirement that it could reasonably be expected to affect the result.
- A trial judge is entitled to find collusion where the evidentiary record reveals a striking, detailed, and selective alignment between defence witnesses’ accounts — particularly where the witnesses are proven to have discussed the events prior to trial — and to factor that finding into a credibility assessment without breaching procedural fairness.
- Appellate courts owe significant deference to a trial judge’s assessment of the degree to which any risk of collusion affects a witness’s evidence, as this forms part of the broader credibility analysis.
- A self-defence claim can properly be rejected on the basis of objective evidence — including the nature, severity, and distribution of the victim’s injuries — where that evidence is incompatible with the accused’s account of a defensive encounter.
Why It Matters
This decision offers useful appellate guidance on the treatment of witness collusion in criminal trials. It confirms that a collusion finding need not be speculative or procedurally unfair where it is grounded in the precision and pattern of evidentiary alignment, and it clarifies that such a finding is properly understood as one factor within — not a distorting override of — the trial judge’s overall credibility assessment. Defence counsel and trial judges alike will benefit from the court’s clear articulation of the distinction between intentional and unintentional collusion and their respective effects on credibility versus reliability.
The case also reinforces the principle that self-defence claims can be defeated by objective medical and physical evidence. Where the severity and distribution of a victim’s injuries are fundamentally incompatible with the accused’s account of a brief defensive struggle, a trial judge is entitled to reject the claim without this constituting a misapprehension of material evidence — a conclusion that will be accorded deference on appeal.
