The appeal concerned sentence fitness for refusing to provide a breath sample after an accident causing death, where the offender was found not impaired and had acted on incorrect state-provided legal advice.
The Court held that sentencing for this refusal offence must remain proportionate to the offence itself and cannot punish uncharged driving offences.
It confirmed that collateral consequences, including vigilante violence, may be considered but with restrained weight, and that mistake of law may mitigate where it genuinely reduces moral blameworthiness.
The custodial term imposed on appeal was set aside and replaced with time served, while the driving prohibition remained in force.
