Mustafa Muhumed v The Queen

Mustafa Muhumed appealed against his sentence for three charges of armed robbery and committing an indictable offence while on bail, as well as throwing a missile to injure. The respondent, The Queen, was represented in the High Court of Australia. The primary legal issue was whether the disparity in sentences between the applicant and his co-offender offended the parity principle, and whether the disparity was manifestly excessive. The court had to consider the differences in personal circumstances and roles played in the offending, as well as the age, backgrounds, and criminal histories of the parties.

The High Court held that the sentencing judge had appropriately considered the differences in personal circumstances and roles played by the applicant and his co-offender. The applicant had a substantial criminal history and was not the principal offender, while the co-offender was a youthful offender with a very moderate criminal history, serving their first sentence in an adult jail. The co-offender had pleaded guilty at the first opportunity and demonstrated remorse, while the applicant only pleaded guilty to related summary charges and offered to plead guilty to certain lesser alternative charges. The court found that the disparity in sentences was reasonably open and not manifestly excessive.

The appeal was dismissed, and leave to appeal was refused. The court concluded that the sentencing judge had properly exercised their discretion, taking into account the relevant factors, and that the disparity in sentences did not offend the parity principle.
