Judge deemed offside for ruling based on hockey details

In a uniquely Canadian miscarriage of justice, a highprofile assault trial will need to be repeated after a judge relied on her own armchair hockey knowledge to convict a beer-league player.

In one particularly egregious example, the judge rejected the entire testimony of a witness simply because she assumed that no coach would have sent three defencemen onto the ice in the closing minutes of a losing game.

In a Court of Appeal decision overturning the conviction, Justice William Hourigan noted that the accused player should have been tried “based on the evidence at trial, not on the hockey experience of the trial judge.”

He added, “hockey strategy is not a proper subject for judicial notice.”

The case surrounded Gordon MacIsaac, a defenceman in the Ottawa Senior Men’s Hockey League who was charged with aggravated assault after allegedly delivering a “deliberate blindside hit” to an opposing player.

In the closing minutes of a 2012 game between the Pirates and the Tiger-Cats, MacIsaac — a TigerCat — allegedly jumped into the air with arms raised and delivered a swift blow to opponent Drew Casterton.

Casterton, a personal trainer, lost both of his front teeth and suffered a concussion. Still plagued by debilitating headaches, Casterton told the court that he remains unable to work more than six hours per week.

MacIsaac and his lawyer, however, have argued that Casterton had the puck at the time — and that the collision was an unavoidable accident.

Although MacIsaac was convicted and sentenced to 18 months’ probation, the ruling was thrown into doubt when appeal judges noted that the decision was peppered with Ontario Court Justice Diane Lahaie’s own biases about hockey strategy.

For one, Tiger-Cat Ryan Robinson claimed to have been in the game when the collision occurred, but the judge rejected his testimony because he would have been one of three defencemen on the ice at the time.

Wrote Lahaie, “it was not logical that three Tiger-Cats defencemen would be on the ice in the last minute of the game when the TigerCats were down by two goals.”

In fact, teams in the Ottawa Senior Men’s league typically sent out their best players in a game’s final minutes, without regard to position.

The judge also made another assumption about defencemen to reject a key claim from MacIsaac that he had accidentally smashed into Casterton while making a play for the Pirates’ net.

“It defies logic that Mr. MacIsaac, a defenceman, would have gone to the net in hopes of scoring a goal,” she wrote.

Lahaie also made repeated guesses about the relative hockey skill of both MacIsaac and Casterton.

MacIsaac couldn’t have accidentally smashed into Casterton, she wrote, because if he was really making a play for the net “he would have had to have more control over his speed.”

MacIsaac’s testimony, Lahaie ultimately concluded, was “not consistent with the injuries sustained by (Casterton).”

As the appeal court noted, no medical expert had testified at the trial, and Lahaie had apparently used little more than photos to decide that Casterton’s injuries had been inflicted intentionally.

The Monday decision quashes MacIsaac’s conviction on the basis of Lahaie’s “speculative reasoning.” A date for a new trial has not been set.
