An accused who is subject to a dangerous offender order may appeal under s. 759(1) on grounds of law, fact, or mixed fact and law. The appeal is different from a sentence appeal. The reviewing court looks at "legal errors and whether the dangerous offender designation was reasonable".
A dangerous offender designation is reviewable on a standard of reasonableness.It is also reviewable on correctness for errors of law.
The appellate court cannot have a "fresh look" at the designation and deference must be paid to the sentencing judge's findings.
