United States v. Booker
The Supreme Court ruled that the federal Sentencing Guidelines violated the Sixth Amendment right to a jury trial whenever they let judges increase a sentence based on facts the judge alone found, rather than facts a jury found or the defendant admitted.
To fix the problem, a different five-justice majority struck down the law that made the Guidelines mandatory, transforming them from binding rules into advisory guidance that judges must consult but need not follow, reshaping federal sentencing nationwide.
“Any fact (other than a prior conviction) which is necessary to support a sentence exceeding the maximum authorized by the facts established by a plea of guilty or a jury verdict must be admitted by the defendant or proved to a jury beyond a reasonable doubt.”
The Court's core holding extending Apprendi and Blakely to the Federal Sentencing Guidelines.
How it got here: The Seventh Circuit ruled Booker's sentence unconstitutional and remanded; the government sought certiorari before judgment in Fanfan's case from the First Circuit, and the Supreme Court granted both petitions together.
The Case in Depth
What happened
Booker was convicted by a jury of possessing over 50 grams of crack cocaine, but the judge, after trial, found by a preponderance of the evidence that he had possessed additional drugs and obstructed justice, raising his sentence from about 22 years to 30 years. Fanfan was convicted of a drug conspiracy, and the judge similarly found extra facts that would have raised his Guidelines sentence, but declined to apply them after Blakely v. Washington was decided.
The question before the Court
Do federal judges violate the right to a jury trial when they increase a defendant's prison sentence based on facts the judge alone found, rather than facts a jury found?
Why it matters
Federal judges no longer have to impose a sentence within the Guidelines range; they now treat the range as one factor among several. This affects nearly every federal criminal sentence going forward, gives judges more discretion, and requires appeals courts to review sentences only for 'reasonableness' rather than strict compliance with the old mandatory ranges.
What changes now
Booker's case is remanded for resentencing under the new advisory system; Fanfan's sentence, already based only on jury-found facts, stands but can be revisited if the government or Fanfan seeks resentencing. Because this is a final merits decision, the new rules apply to all cases still on direct review nationwide, so federal sentencing courts everywhere immediately shifted from mandatory to advisory Guidelines, with appeals reviewed for reasonableness. Congress remains free to enact new sentencing legislation.
What this does not decide
The Court did not hold that judges can never find sentencing facts — judicial fact-finding remains constitutional so long as it does not push a sentence above what the jury's findings alone would authorize. The decision also does not itself specify how 'reasonableness' review should work in practice, leaving that to lower courts to develop over time.
Concurrences and dissents
Dissent — Justice Stevens
Stevens (joined fully by Souter, and by Scalia except Part III and footnote 17) agreed the Guidelines violated the Sixth Amendment but rejected the remedy. He argued the Court should have simply required juries to find sentence-enhancing facts while leaving the mandatory Guidelines structure intact, since Congress had repeatedly and explicitly chosen binding guidelines and never contemplated the discretionary system the majority created. He viewed the remedial majority's severability analysis as an unprecedented exercise of legislative rather than judicial power.
Dissent — Justice Scalia
“In order to rescue from nullification a statutory scheme designed to eliminate discretionary sentencing, it discards the provisions that eliminate discretionary sentencing.”Scalia's criticism that the remedy ironically undid Congress's central goal of uniform sentencing.
Scalia joined Stevens's dissent (except Part III and footnote 17) and wrote separately to criticize the remedial opinion's overhaul of appellate review. He argued that excising the standard-of-review provision while leaving the rest of the appeals statute intact made no sense, that the 'reasonableness' standard was not truly grounded in existing law, and that the remedy would produce inconsistent sentencing outcomes across courts.
Dissent — Justice Thomas
Thomas joined Stevens's opinion on the constitutional violation but dissented from the remedy, arguing the Court should have invalidated the mandatory Guidelines only as applied to defendants like Booker who actually suffered unconstitutional judicial fact-finding, leaving the Guidelines standing for everyone else under ordinary as-applied severability principles rather than facially converting the whole system to advisory status.
Dissent — Justice Breyer
Breyer, joined by Rehnquist, O'Connor, and Kennedy, dissented from the constitutional holding itself, arguing history does not support treating sentencing facts the same as elements of a crime requiring jury findings, and that applying Apprendi and Blakely to the administratively-written Guidelines risked unwieldy trials and undermined Congress's goal of reducing sentencing disparity through real-conduct sentencing.
How the Court got there
The legal reasoning, step by step
- Building on Apprendi v. New Jersey and Blakely v. Washington, the Court applied the rule that any fact (other than a prior conviction) that increases a defendant's sentence beyond what the jury's verdict alone would support must be found by a jury beyond a reasonable doubt, not by a judge using a lower 'preponderance of the evidence' standard.
- The Court found no meaningful difference between the Washington state sentencing scheme struck down in Blakely and the Federal Sentencing Guidelines, because both systems made the sentencing rules binding on judges rather than merely advisory, so the same constitutional problem applied to the federal system.
- Having found the constitutional violation, a separate majority then addressed the remedy through severability analysis: predicting what Congress would have wanted done if it had known the mandatory Guidelines could not survive intact given the jury-trial requirement.
- The remedial majority concluded that Congress would have preferred making the Guidelines advisory rather than either grafting a jury-fact-finding requirement onto the existing mandatory system or invalidating the entire Sentencing Reform Act, because an advisory system better preserved Congress's goal of tying sentences to real offender conduct.
- To achieve this, the Court severed and excised two statutory provisions: the section making the Guidelines mandatory and the section setting the standard of appellate review, replacing the excised review standard with an inferred 'unreasonableness' standard for sentences on appeal.
Doctrinal impact
Cases affected by this decision
Reaffirms Apprendi v. New Jersey (530 U.S. 466)
The Court reaffirmed and extended Apprendi's rule that facts increasing a sentence beyond the authorized maximum require jury findings.
Reaffirms Blakely v. Washington (542 U.S. 296)
The Court applied Blakely's definition of 'statutory maximum' directly to the Federal Sentencing Guidelines.
Distinguishes Mistretta v. United States (488 U.S. 361)
The Court held its Sixth Amendment ruling did not undermine Mistretta's approval of the Sentencing Commission's structure.
