The offender was convicted of assault causing bodily harm after punching the victim in the jaw at a cottage party.
The victim sustained a broken jaw in four places, chipped teeth, and ongoing physical and psychological injuries.
The Crown sought six to nine months imprisonment, emphasizing denunciation and deterrence of vigilantism.
The defence sought a conditional discharge with community service or intermittent weekend jail time.
The court imposed four months incarceration followed by one year probation, finding that denunciation and general deterrence required jail time and that a conditional sentence was inappropriate despite being technically available.
