Well, I've raised that personally with a number of judges. They didn't seem to think so.
I guess it depends on the jurisdiction you're in. In some jurisdictions the types of conditions that can be imposed under a suspended sentence and the probation order are quite broad. Some have indicated to me they are virtually identical to the conditional sentence.
My own problem with conditional sentences is not in theory but with why we have them at all. Why don't we simply amend probation orders, if there is an issue with respect to them? The probation orders are much easier to enforce than conditional sentences. During a two-year suspended sentence, for example, you can bring back the person at any time in the course of that sentence and resentence the individual and really hold the person accountable for the full two years. You can't do that with a conditional sentence, and that's one of the serious concerns about a conditional sentence.
