Background
Seyed Ramin Moshfeghi Zadeh drove through a red light at a busy downtown Vancouver intersection. His vehicle collided with another vehicle and mounted the sidewalk, striking a father and his 18-month-old daughter. The father was severely injured and the child was killed. Moshfeghi Zadeh was charged with dangerous driving causing death and dangerous driving causing bodily harm.
At trial, he conceded that his driving was dangerous to the public, satisfying the offences’ actus reus. The only disputed issue was mens rea: whether his conduct was a marked departure from the standard expected of a reasonable driver in the circumstances. The trial judge characterized the incident as three to five seconds of inattention and acquitted him, stating that a momentary lapse of judgment without more could not establish dangerous driving. A majority of the British Columbia Court of Appeal upheld the acquittals despite recognizing that this statement misstated the law; the dissenting judge would have ordered a new trial.
The Court’s Holding
By a 5-4 majority, the Supreme Court allowed the Crown’s appeal, set aside the acquittals and ordered a new trial. Justice O’Bonsawin held that a momentary lapse of attention, without anything more, can amount to the marked departure required for dangerous driving. There is no separate rule for brief lapses: the court must assess all the evidence and ask whether a reasonable person would have foreseen the risk and taken steps to avoid it, and whether the accused’s failure to do so was a marked departure from the applicable standard of care.
The trial judge’s erroneous “momentary lapse without more” premise materially shaped her analysis. It caused her to focus on the duration of the inattention rather than the surrounding risks, including the busy downtown setting, pedestrians, several stale red lights visible from a distance and the adjacent vehicle slowing and stopping. The Supreme Court declined to enter convictions because the trial judge had not made the comprehensive factual findings needed to apply the correct test. Four dissenting judges would have upheld the acquittals, concluding that the trial judge’s isolated misstatement did not materially affect her otherwise contextual analysis.
Key Takeaways
- A momentary lapse of attention can, by itself, satisfy the mens rea requirement for dangerous driving if it amounts to a marked departure from the care expected of a reasonable driver.
- Duration is relevant but not controlling; courts must assess the lapse in its full context, including location, speed, road conditions, visible hazards and the immediacy of foreseeable harm.
- A Crown appeal from an acquittal requires a material error of law, and an appellate court may substitute a conviction only in rare cases where the necessary findings of guilt have already been made.
Why It Matters
The decision rejects any bright-line protection from criminal liability for driving errors characterized as brief or momentary. It directs trial courts to evaluate the risk created by inattention in the specific driving environment, rather than treating the lapse’s short duration as presumptively inconsistent with criminal fault.
The judgment also illustrates the limits of appellate remedies after an acquittal. Although the majority found a material legal error, it ordered a new trial rather than convictions because the incomplete factual findings prevented the Court from applying the correct mens rea test itself.
