Concepcion v. United States
The Facts
Carlos Concepcion was convicted on crack cocaine charges and sentenced under mandatory minimums that the Fair Sentencing Act of 2010 subsequently reduced. When Congress passed the First Step Act in 2018 and made the Fair Sentencing Act's reductions retroactive, Concepcion moved for resentencing. The district court declined to consider changed guidelines and Concepcion's post-sentencing conduct, holding those factors were outside its authority. The First Circuit affirmed.
The Application
Applying Section 3553(a)'s broad sentencing discretion, a resentencing court may look beyond the new guideline range to consider how Concepcion's circumstances have changed since his original sentence: including the legal landscape that shifted when the Fair Sentencing Act reductions became retroactive under the First Step Act, as well as his conduct and rehabilitation during his years of incarceration. The lower courts had treated resentencing as mechanically applying the new guidelines, treating post-sentencing developments as off-limits, but Section 3553(a)'s language permits consideration of "all relevant information" in fashioning a sentence. However, this discretion is permissive: the resentencing court may hear Concepcion's evidence of changed circumstances and rehabilitation, but it is not obligated to credit it or grant a reduced sentence based on it. The ruling thus establishes that resentencing is not a box-checking exercise, but permits courts to weigh the full picture of a defendant's life and desert.
The Conclusion
**Sentencing courts have discretion to consider the full picture of a defendant's circumstances at a First Step Act resentencing, but they are not compelled to do so or to grant relief.** The ruling allows defendants who have served long sentences under pre-reform crack guidelines to present evidence of rehabilitation and changed legal landscape to the resentencing court.
No circuit court data for this case.
Case Analysis
Overview
The Supreme Court held 5-4 that district courts conducting resentencings under the First Step Act of 2018 may consider all legally relevant information, including post-sentencing developments, but are not required to do so sua sponte. Justice Jackson wrote for the majority in her first authoring opinion.

Issue
Whether a district court conducting a First Step Act resentencing may consider intervening changes in law and the defendant's conduct during incarceration, or whether its discretion is limited to applying the new sentencing range.
Rule
The First Step Act makes the Fair Sentencing Act's crack cocaine sentence reductions retroactively applicable. District courts have broad discretion under 18 U.S.C. Section 3553(a) to weigh all relevant factors at sentencing, including developments that occurred after the original sentence was imposed.
