Joseph Schulte pleaded guilty to one count of violating 18 U.S.C. § 2252(a)(4)(B), which prohibits the possession of child pornography that has. traveled in interstate commerce. Although Wisconsin law also cidminalizes this conduct, Schulte was prosecuted in federal court and, consequently, sentenced in accordance with the Sentencing Guidelines. Schulte moved for a downward departure because state law punished the same criminal conduct less severely than the sanctions mandated by the Sentencing Guidelines. The district court denied his motion to depart, and Schulte received a sentence of fifteen months imprisonment and three years of supervised release. We affirm the district court’s refusal to consider Schulte’s proposed ground for departure.
I.
Joseph Schulte communicated with an undercover FBI agent through an Internet “chat room” provided by America On Line. The agent, using the moniker “Syberslave,” investigated the transmission of child pornography as part of a federal task force. In one particular on-line group discussion, Schulte demonstrated a willingness to trade child pornography and to aid others in their efforts to scan such images onto their computer systems. In fact, Schulte transmitted thirteen images of children engaged in sexual conduct to the undercover federal agent. The Government thereafter conducted a *1109 search of Schulte’s residence in Madison, Wisconsin. The fruits of this search included the thirteen images transmitted to the Government’s agent, as well as computer disks that contained images of young children engaged in sexually-explicit behavior.
Schulte pleaded guilty to one count of possessing child pornography in violation of 18 U.S.C. § 2252(a)(4)(B). At his sentencing hearing, the district court rejected his motion to depart downward from the 15 to 21 month range prescribed by the Sentencing Guidelines. Schulte pointed to a few cases in which defendants prosecuted for similar conduct in state court received only a three-month term of imprisonment. The district court held that it lacked authority to depart on the basis of this disparity between state and federal sentences:
I believe that it’s not appropriate within the sentencing guidelines and the whole context of the guidelines to lower a sentence simply to confoim to what is being done as a general matter in state court.... We cannot depart downward just because we think somebody in front of us is for all kinds of reasons not deserving of the type of sentence that Congress and the Sentencing Commission has said was appropriate. It is not appropriate to go downward because the state courts are generally sentencing at the lower level.
The court then sentenced Schulte to fifteen months imprisonment, the lowest possible sentence within the range mandated by the Sentencing Guidelines.
II.
This appeal requires us to decide whether a district court may depart from the punishment prescribed by the Sentencing Guidelines based on a disparity between that punishment and the sanction imposed for similar conduct in the relevant state court. Our starting point is the Supreme Court’s decision in
Koon v. United States,
Unmentioned factors, by definition, do .not receive any .sort of explicit endorsement or prohibition in the Guidelines. In
Koon,
the Court stated that departures based on unmentioned factors are permissible only if a sentencing court determines that “the factor, as occurring in the particular circumstances, takes the case outside the heartland of the applicable Guideline.”
Despite the best efforts of the Commission and the Supreme Court to formulate abstract definitions of the heartland standard, it remains an elusive concept in application.
Koon
instructs' lower courts to draw the boundaries of the heartland with reference to both the specific guidehne(s) at, issue in a case and the structure and policies of the Guidelines as a whole.
See
Like the defendant in
Meza,
Schulte seeks a downward departure based on a sentencing disparity. He correctly posits that the disparity between state and federal punishments for identical conduct is not mentioned by the Guidelines as a potential ground for departure. Our analysis, therefore, shifts to the heartland determination. Schulte claims that his case falls outside the heartland because of the disparity between his fifteen-month prison sentence in federal court and the much shorter prison terms allegedly received by similarly-situated defendants in state court. Schulte essentially contends that the Sentencing Guidelines create an unjustified disparity because they impose a more onerous sentence on a defendant for conduct that would have called for a less severe punishment in state court. He argues that perpetuating such disparities disrupts the “evenhandedness and, neutrality that are the distinguishing marks of any principled system of justice.”
Koon,
Schulte’s argument, however, proceeds from a fundamentally flawed premise. The federal government can only mandate uniform sentences for those offenses within its jurisdiction. The Sentencing Commission properly stated its limited authority and purpose: “[T]o establish sentencing policies and practices for
the federal criminal justice system
that will assure the ends of justice by promulgating detailed guidelines prescribing the appropriate sentences for offenders convicted of
federal crimes.”
U.S.S.G. Ch. 1, Pt. A(1), intro, comment, (emphases added). The Guidelines have no effect on a state legislature’s freedom to impose criminal punishments that differ from the federal government’s sanctions for the same conduct. The Guidelines seek uniformity, not with respect to federal and state sentences, but rather
*1111
among federal sentences for similar conduct. Schulte does not complain of a disparity between his sentence and those received by other
federal
offenders, the only group similarly situated to him. A disparity is not “unjustified” simply because the federal and relevant state governments impose different punishments on similar conduct. One cannot say—-as is required to remove a case from the heartland-that such a disparity occurred as a result of an improper application of the Guidelines.
See Meza,
We conclude that a disparity between federal and state sentences does not take a case out of the heartland of cases contemplated by the Sentencing Commission. Indeed, recognizing this ground for departure would undermine the operation of the Guidelines. If courts were to depart from the sentences mandated by the Guidelines in deference to numerous and varying standards in the state systems, they would eviscerate the uniformity in federal sentencing that is the
raison d’etre
of the Sentencing Reform Act of 1984.
See, e.g., United States v. Haynes,
III.
For these reasons, we do not deem Schulte’s case removed from the “heartland” because there exists a disparity between the state and federal punishments for his criminal conduct. Since the challenged disparity is within the heartland, then, the district court did not err in refusing to consider a departure on this ground. We affirm Schulte’s sentence.
