Gary George served in Wisconsin’s Senate for 23 years, acquiring considerable influence over public expenditures. He was indicted in 2003 on charges that he accepted kickbacks in exchange for exercising that influence, which extended over federal grants as well as programs financed by state revenues. He pleaded guilty to violating 18 U.S.C. § 371 (conspiracy to defraud the United States) as part of a bargain in which the prosecutor dismissed all other charges, and he was *472 sentenced to 48 months’ imprisonment pins about $614,000 in restitution.
Four months after pleading guilty, George moved to dismiss the single count of conviction under Fed.R.Crim.P. 12(b)(3)(B) for failure to state an offense. Relying on
United States v. Bloom,
Actual innocence might supply a “fair and just reason” to withdraw a guilty plea, see Fed.R.Crim.P. 11(d)(2)(B), but George did not move to withdraw his plea in order to set the stage for a motion to dismiss- — for withdrawal would have allowed the prosecutor to reinstate the remaining charges, including two counts under 18 U.S.C. § 666 and one under 18 U.S.C. § 1956(a)(1)(B)(i), none of which entailed honest-services fraud. (And George had pleaded guilty; his contention that the district judge failed to accept his plea is incorrect and need not be discussed.)
A district judge has discretion under Fed.R.Crim.P. 12(b)(3)(B) “at any time while the case is pending ... [to] hear a claim that the indictment or information fails to invoke the court’s jurisdiction or to state an offense”. A judge might elect to use this discretion to treat a motion such as the one George made as a request to withdraw the plea and dismiss the contested charge — though relieving the defendant of the concessions he made would relieve the prosecutor of the reciprocal concessions and reinstate the other charges. The district judge did not abuse his discretion in denying George’s motion, however. It was made late in the day (only two weeks before sentencing) and rested on a misunderstanding. The count to which George pleaded guilty did not depend on § 1346. It charged him with conspiring to defraud the United States, not with depriving Wisconsin of his honest services. Mail fraud was just one of the means employed in the scheme. The district judge sensibly perceived that George was trying to smuggle an objection to the sufficiency of the evidence (which Rule 12(b)(3)(B) does not cover) into the proceeding under the guise of a challenge to the charge’s statutory footing.
George submits that his sentence violates the sixth amendment, as the Supreme Court explained it in
United States v. Booker,
— U.S. -,
The Supreme Court’s decision in
Booker
shows that the Guidelines continue to inform district judges’ decisions. Judges need not rehearse on the record all
*473
of the considerations that 18 U.S.C. § 8553(a) lists; it is enough to calculate the range accurately and explain why (if the sentence lies outside it) this defendant deserves more or less. That’s the approach we have taken for decisions to reimprison a person after revoking supervised release, a subject on which the Guidelines always have been advisory rather than binding. See
United States v. Salinas,
George does not contend that his actual sentence is unreasonable, the post-Booker standard of appellate review. It is hard to conceive of below-range sentences that would be unreasonably high. George’s is not. The United States would have better claim to be the party aggrieved by the district judge’s disposition, and it has not appealed.
Restitution poses a more complex problem. George’s contention that
Booker
requires juries rather than judges to assess restitution is misguided. There is no “statutory maximum” for restitution; indeed, it is not a criminal punishment but instead is a civil remedy administered for convenience by courts that have entered criminal convictions, see
United States v. Bach,
Still, restitution must be calculated in accord with statutory rules, and we cannot be confident that the district judge did so. The presentence report and witnesses who testified at a hearing offered different estimates of appropriate restitution, with the low end around $200,000 and the high end around $900,000. Choice depended on a number of variables, such as whether to treat George’s gains as a proxy for the sums diverted from the public programs and what value to assign to time that public employees and private contractors devoted to providing campaign aid, accounting help, and other services to George personally. George contended that the answer is zero because employees put in full days on the job, so that the public lost nothing; the prosecutor denied this and added that if workers were willing to pull overtime they should have done so for public rather than private benefit.
The district judge chose $613,746.36 as the amount of restitution but did not make findings of fact or articulate his reasons. Although Fed.R.Civ.P. 52(a) does not apply directly to restitution, even though it is fundamentally a civil remedy awarded after a bench trial, Circuit Rule 50 does require an explanation for all appealable orders. When the district judge omits findings about contested amounts of restitution, it may be impossible to tell whether the legal rules have been applied correctly.
United States v. Menza,
Restitution must be based on the victim’s loss rather than the offender’s gain. Compare
United States v. Shepard,
The presentence report invited consideration of amounts that are inappropriate under one or more of these rules. It covered the events underlying all five counts of the indictment, even though George pleaded guilty to just one. It tried to tote up George’s gains, though these may differ from the victim’s losses. It assumed that the State of Wisconsin is the victim, though the crime of which George has been convicted is conspiring to defraud the United States. Witnesses at the evi-dentiary hearing likewise made one or more of these errors. Perhaps Wisconsin should be treated as an additional victim under § 3663A(a)(2) because it lost the benefit of funds provided by the United States, but this possibility must be explored with care rather than assumed to be true.
Restitution of $614,000 may or may not be right; we just cannot tell. Accordingly we vacate that portion of the judgment and remand with instructions to receive written submissions from the parties addressing the considerations we have mentioned, and then make findings and conclusions based on the existing record. The conviction and sentence of imprisonment are affirmed.
