Petition Pending

Awaiting an order on the petition

No decision timeline until the Court agrees to hear the case.

What it’s about
Jony Rene Perez-Montano filed a petition asking the Supreme Court to decide whether judges may use detailed U.S. Sentencing Commission statistics when assessing whether a sentence creates an unfair difference from sentences for similar defendants.
What's at stake
It remains unresolved whether judges may use these statistics when comparing a defendant’s sentence with sentences for similar defendants.

Summary: written with AI from the case record.

What it's about

Federal law tells sentencing judges to consider avoiding unwarranted differences among similar defendants; Perez-Montano asks whether the Commission’s JSIN statistics are relevant to that task.

Question presented

Are the detailed Judiciary Sentencing Information (JSIN) statistics compiled by the United States Sentencing Commission relevant to considering whether a defendant’s sentence creates an unwarranted sentencing disparity compared to similarly situated defendants under 18 U.S.C. § 3553(a)(6)?

What happens next

The next step is for the Court to decide whether to hear the petition. No oral argument or decision window exists unless the Court grants review.
