In a landmark decision, Judge Nancy Gertner granted one of Mr. Budreau's clients a downward departure in his sentence from 57 months to time served or 15 months on the grounds that his compulsive gambling disorder satisfied a claim of aberrant conduct. See United States v. Iaconetti, 59 F.Supp.2d 139 (1999). As discussed in the Sentencing in Federal Court System section herein, the federal courts use sentencing guidelines which are considered presumptive. In United States v. Booker, a 2005 opinion, the United States Supreme Court ruled that the guidelines were no longer mandatory but were instead advisory and presumptive. In other words, if the accused is able to demonstrate grounds for a reduced sentence, then the court can depart from the presumptive guidelines sentence based upoin its discretion and subject to possible review by the appeals court for reasonableness.
