Judges are capable of delivering consistency. Judges are trained professionals and must demonstrate competence in order to be appointed- they are unlikely to administer completely random sentences. In order to further reduce inconsistency, the Con supports government-issued sentencing guidelines so that judges are aware of the precedent concerning sentencing for a particular crime, so long as these guidelines are not compulsory. In the unusual occurrence that a judge administers an unjustly harsh sentence, defendants may appeal their case to a higher court. Thus judicial discretion is unlikely to result in widespread inconsistent sentencing.
