In all sexual assault cases I'd have a presumption against conditional sentences. If the defence lawyer can demonstrate on the circumstances of that particular case why the offender can remain in the community, and still produce an appropriate sentence, then it's an appropriate outcome in the case.
The reason a presumption is important is if a judge ends up giving a conditional sentence where it's not fit, the Crown can go to the Court of Appeal and have a good basis for appeal, because the principles of sentencing have not been respected. Absent those kinds of directions, you have tremendous sentencing discretion, and courts of appeal don't like to interfere with judges' sentencing. But if you have the principles codified, then the Court of Appeal will have a foundation for interfering with inappropriate sentences.
