Conditional discharges can be granted if the convicted offense is minor and your record shows no previous related convictions.
If the judge grants you a conditional discharge, there will be strict rules to follow including a curfew and if those rules are broken, the court may decide have you complete your remaining sentence in jail. This type of discharge can only be granted if the judge does not find you a threat to the community, and your record must not show similar offenses in the past.
After three years your conditional discharge will be removed from your record, but to ensure this is the case it is suggested that you apply for a Pardon.
