Andrew Neidinger appeals the modified sentence imposed upon him by the district court for willful failure to file a federal income tax return for 1974, in violation of 26 U.S.C. § 7203. Neidinger was originally sentenced on July 3, 1980 to one year of imprisonment, on the condition that he be confined in the Montgomery County Detention Center for thirty days and placed on work release. The district court suspended execution of the remainder of the sentence- and ordered that Neidinger be put on probation for two years, the probationary period to commence following his release from confinement. Neidinger was ordered to report to the Detention Center upon written notice from the United States Marshal, and, in the absence of such notice, he was to surrender himself to the Marshal on July 24, 1980. Subsequent to the July 3rd hearing, and before Neidinger was placed in confinement, the district court learned that the Montgomery County Detention Center would not accept Neidinger for a thirty day work release program. The court therefore requested Neidinger to appear on July 16th for sentence modification. At that time, the court suspended execution of the entire one year sentence and placed Neidinger on immediate probation for two years, requiring him as a condition of probation to reside in the Montgomery County Pre-Release Center (a halfway house) for sixty days on work release.
Neidinger argues that the modified sentence increased his original sentence after *410 he had commenced to serve it, and that it therefore violated the Fifth Amendment guarantee against double jeopardy.
We are not persuaded by this argument. Constitutional protection against double jeopardy does not attach prior to the commencement of a sentence.
See, e. g., United States v. Bynoe,
We therefore are constrained to review the sentence with regard only to its legality, that is, whether the sentence falls within the statutory limits, and to the question of whether the district court in fact exercised discretion in sentencing.
See, e. g., United States v. Bowser,
We find that the modified sentence is clearly legal: the one year suspended sentence does not exceed the one year statutory limit set forth in 26 U.S.C. § 7203, and the two year probationary term with provision for a sixty day residence at the Pre-Release Center meets the statutory terms of 18 U.S.C. § 3651. 3 The sentence being legal, we are left only with the in *411 quiry of whether the district court indeed exercised discretion in sentencing Neidinger. The record indicates that the district court did not mechanistically sentence Neid-inger but instead acted with discretion and took both societal considerations and Neid-inger’s personal circumstances into account in fashioning the punishment.
Because the modified sentence is legal, is the product of the district court’s discretion, and does not place Neidinger in double jeopardy, we affirm it.
AFFIRMED.
Notes
. 18 U.S.C. § 3568 states in relevant part that “[t]he sentence of imprisonment of any person convicted of an offense shall commence to run from the date on which such person is received at the penitentiary, reformatory, or jail for service of such sentence.”
. The original sentence in this case termed Neidinger’s confinement in the Montgomery County Detention Center a “condition” of the sentence. As 18 U.S.C. § 4082(a) requires that a person who is convicted and sentenced be “committed ... to the custody of the Attorney General of the United States, who shall designate the place of confinement,” the “condition” placed by the district court on the sentence of imprisonment was, legally, mere surplusage. See
In re Grand Jury Proceedings,
. 18 U.S.C. § 3651 provides in relevant part as follows:
... if the maximum punishment provided for such offense is more than six months, any court having jurisdiction to try offenses against the United States ... may impose a sentence in excess of six months and provide that the defendant be confined in a jail-type institution or a treatment institution for a period not exceeding six months and that the *411 execution of the remainder of the sentence be suspended and the defendant placed on probation for such period and upon such terms and conditions as the court deems best.
