Ms. Stevens appealed both her conviction and sentence for impaired operation causing death and dangerous operation causing death. The sentence appeal was dismissed as her sentence was "not outside the range of sentence appropriate for similar offenders who commit similar offences in similar circumstances." Her conviction appeal was also dismissed:
A toxicologist testified that at the time of the accident, Ms. Steven’s blood alcohol concentration was between 70 and 110 milligrams of alcohol per 100 millilitres of blood. There was also evidence that, at a blood alcohol concentration of 50 milligrams per 100 millilitres of blood, impairment of the ability to operate a motor vehicle becomes significant, at least in a scientific sense.
