R v MacIsaac

R. v. MacIsaac

2015 ONCA 587
Court of Appeal for Ontario — Hourigan J.A. | August 31, 2015

Background

Gordon MacIsaac was playing in a "no-contact" recreational hockey league in Ottawa when he collided with an opponent during the final 47 seconds of a March 15, 2012 game. The collision left the complainant with facial lacerations, two missing front teeth, a concussion, and ongoing daily headaches. MacIsaac was charged with aggravated assault.

The Crown argued MacIsaac deliberately delivered a blindside hit to retaliate for an earlier tripping incident. MacIsaac claimed it was an unavoidable accident when both players were skating toward the puck. The case came down to conflicting witness testimony — Crown witnesses said MacIsaac raised his arms and lifted his skates off the ice before contact, while defence witnesses said both players were facing each other and the collision was accidental.

Issues

1. Did the trial judge engage in impermissible speculative reasoning?
2. Did the trial judge reverse the burden of proof?
3. Did the trial judge err in failing to consider honest but mistaken belief in consent?

The Speculative Reasoning Problem

The Court of Appeal found that Justice Lahaie made a series of crucial errors by rejecting defence evidence based on her own assumptions about hockey rather than the actual evidence. She rejected one defence witness's testimony because "it was not logical that three Tiger-Cats defencemen would be on the ice" late in the game — despite evidence that teams in this league play their most skilled players regardless of position in crucial moments.

The trial judge also rejected MacIsaac's explanation of his actions, saying "it defies logic that Mr. MacIsaac, a defencemen, would have gone to the net in hopes of scoring a goal" when his team was down by two goals. She criticized his speed and control based on her personal understanding of hockey strategy, not expert evidence. Most problematically, she concluded MacIsaac's testimony was "inconsistent with the injuries sustained by the complainant" without any medical or expert evidence to support that conclusion.

The Court of Appeal ruled this crossed the line into impermissible speculation. Trial judges can draw reasonable inferences from established facts, but they cannot reject evidence based on their personal knowledge of subjects like hockey strategy, especially when no expert testimony was presented.

Key Takeaway

Trial judges cannot use their personal knowledge or assumptions to fill gaps in the evidence or reject witness testimony.

When a judge starts making factual determinations based on their own understanding of sports, medicine, or other specialized areas without proper evidence, they've stepped outside their role as neutral arbiters. The accused has a right to know what case they're defending against — not to be surprised by the judge's personal theories about how hockey should be played.
