The door closed on a second attempt to undo the conviction.
In the years since a Calgary police officer was captured on camera throwing a handcuffed woman face-first to the ground, the legal system has slowly, imperfectly, turned its gears toward accountability. Alex Dunn's conviction for assault causing bodily harm has now survived two rounds of appeal, with courts affirming that the evidence against him was beyond dispute. Yet the woman at the center of it all, Dalia Kafi, did not live to see justice reach its present form — and the question of whether a 30-day conditional sentence truly reflects the gravity of what was done to her remains unresolved.
- Security footage from 2017 left little room for interpretation: a handcuffed woman was thrown to the ground by the officer who held her in custody, her face striking the floor hard enough to bleed.
- Dunn's legal team mounted a second appeal, arguing the original trial judge had unfairly dismissed his credibility and effectively reversed the burden of proof onto the accused.
- Justice Anne Kirker shut the door on that attempt, ruling that Dunn had not met the high threshold required to appeal an already-appealed conviction, and that credibility findings by trial judges command deference.
- Dalia Kafi died of a suspected overdose in June 2021, days before sentencing — she never witnessed the conviction upheld, and her absence casts a long shadow over every subsequent legal proceeding.
- The Crown's own appeal of Dunn's 30-day conditional sentence is still pending, leaving open the question of whether the punishment will ever match the weight of the offense.
In December 2017, Calgary police constable Alex Dunn took Dalia Kafi into custody for a curfew violation. What security cameras recorded at police headquarters was unambiguous: Dunn threw her to the ground, her face striking hard enough to draw blood. Three years later, a judge convicted him of assault causing bodily harm and sentenced him to 30 days — served as house arrest and a curfew.
Dunn appealed, with his lawyer arguing that the trial judge had been too quick to disbelieve his claim that Kafi had slipped her handcuffs and posed a threat. Justice Robert Hall reviewed the case and upheld the conviction, finding that guilt was inevitable regardless of which version of events one accepted.
This week, Dunn's new lawyer sought permission to mount a second appeal, arguing the original judge had reversed the burden of proof and that the appeal court had simply followed her flawed reasoning without independent scrutiny. Justice Anne Kirker rejected the request, finding that Dunn had not met the legal threshold for appealing an appeal and that no error in the standard of review had been demonstrated.
Dalia Kafi died of a suspected overdose in June 2021, just days before Dunn's sentencing — never alive to see the conviction survive its legal challenges. The Crown, unsatisfied with the leniency of 30 days, has filed its own appeal of the sentence. That hearing is expected next year. For now, the conviction holds, and Dunn's efforts to undo it have been turned back.
In December 2017, Calgary police constable Alex Dunn brought a woman named Dalia Kafi into custody for violating her curfew. Security cameras at police headquarters recorded what happened next: Dunn threw her to the ground, her face striking the floor hard enough to draw blood. The video was unambiguous. In December 2020, a judge found him guilty of assault causing bodily harm and sentenced him to 30 days—a conditional sentence split between house arrest and a curfew.
Dunn appealed. His lawyer argued that the trial judge, Michelle Christopher, had been too quick to disbelieve his account of events. According to Dunn, Kafi had slipped free of her handcuffs and posed a threat; he was acting in self-defense. Justice Robert Hall reviewed the case and upheld the conviction, finding that even if the judge had believed Dunn's version, guilt was inevitable given the evidence.
This week, Dunn's new lawyer, Alain Hepner, asked the Alberta Court of Appeal for permission to mount a second appeal. He contended that Christopher had boxed herself in with her credibility findings, that she had been unfair in assessing Dunn's testimony, and that the appeal judge had simply followed her narrative without properly examining the legal questions at stake. The argument was technical but pointed: Hepner suggested the original judge had reversed the burden of proof, placing an unfair weight on his client to prove his innocence.
Justice Anne Kirker rejected the request. She found that Dunn had not met the legal threshold required to appeal an appeal. Trial judges' assessments of credibility and evidence, she wrote, are entitled to deference. There was no indication that Hall had applied the wrong standard of review. The door closed.
What hangs over this case is a detail that arrived too late to reshape the outcome. Dalia Kafi died in June 2021 of a suspected overdose, just days before Dunn's sentencing hearing. She was not alive to see the conviction upheld, nor to witness the legal machinery grind through its subsequent motions. The Crown, meanwhile, has filed its own appeal—not of the conviction but of the sentence itself, arguing that 30 days is too lenient. That case is expected to be heard next year. For now, Dunn's conviction stands, and his attempt to undo it has been blocked.

Why does a second appeal matter here? Didn't the first appeal already examine everything?
The first appeal looked at whether the trial judge made an error. A second appeal is different—it's asking whether the first appeal judge made an error. It's a much higher bar. You need to show something was fundamentally wrong with how the law was applied.
And Dunn's lawyer argued the trial judge was unfair to him. What was his actual defense?
He said Kafi had slipped out of her handcuffs and was a threat. But there's video. The judge watched it and didn't believe him. Once a judge decides you're not credible, it's very hard to overturn that on appeal.
The sentence was only 30 days. That seems light for assaulting someone in custody.
It does. That's why the Crown is appealing the sentence separately. They think it should be harsher. But Dunn's conviction itself—that's now locked in.
What happened to the woman he assaulted?
She died before his sentencing. Overdose. She never got to see any of this resolved.
Does her death change anything legally?
Not in the way you might hope. The conviction was already secured. Her death is a fact in the record, but it doesn't reopen the case. It just sits there, part of the weight of what happened.
