Sentences with phrase «unenhanced guidelines range»

Can someone explain the meaning of this sentence on page 14 of the majority opinion: «As far as the law is concerned, the judge could disregard the Guidelines and apply the same sentence (higher than the statutory minimum or the bottom of the unenhanced Guidelines range) in the absence of the special facts (say, gun brandishing) which, in the view of the Sentencing Commission, would warrant a higher sentence within the statutorily permissible range.»

Is the Court establishing the bottom of the unenhanced Guidelines range (i.e., using just the base offense level) itself as a mandatory minimum?
