My answer is this. If we create a hierarchy of principles and put proportionality on the top rung, the judge will have to look first at proportionality and then at prevention, in making decisions. I know that prevention, rehabilitation and reintegration are always included in the principles stated by the legislation. But as soon as the hierarchy is changed, the landscape in which judges are making their decisions changes.
