 Some offences carry minimum sentences, for example, certain firearms offences, "three strikes and you're out" burglaries, using someone to mind a weapon, or those committed by dangerous offenders.There are different sentencing provisions for offenders aged ten to seventeen years old, and some modified provisions for those in the 18-20 age range.If a person pleads guilty, or is found guilty of an offence after a trial, the court is required to decide what sentence should be imposed on the offender.
