United States v. Tsarnaev
Headline: Ruling lets federal court keep Boston Marathon bomber’s death sentences, reversing an appellate vacatur and upholding trial-judge discretion over juror media questions and sentencing evidence exclusion.
Holding: The Court held that the trial judge did not abuse discretion by declining the media-content juror question and by excluding the uncorroborated Waltham‑murder evidence, so the death sentences remain in force.
- Affirms judges’ discretion in juror questioning procedures.
- Limits defendants’ ability to force jurors to list media facts.
- Allows exclusion of unproven third‑party crimes at sentencing.
Summary
Background
Two brothers set off pressure-cooker bombs at the 2013 Boston Marathon, killing three people and wounding many others. The younger brother, who hid in a boat and was later arrested, was tried in federal court, convicted on many counts, and sentenced to death for six offenses. Before trial, the judge removed a proposed juror question that would have asked people to list facts they had learned from the media. At sentencing, the judge excluded evidence suggesting the older brother may have been involved in an earlier triple homicide in Waltham.
Reasoning
The central questions were whether the trial judge abused discretion by (1) refusing the juror media-content question and (2) excluding the Waltham-related evidence at sentencing. The Court explained that trial judges have broad authority to run jury selection, and there is no blanket constitutional rule forcing jurors to list media facts. The Court also said federal sentencing law allows wide-ranging mitigation evidence but lets judges exclude material whose probative value is outweighed by risk of unfair prejudice or jury confusion. Because the judge held an extensive voir dire process and reasonably found the Waltham material unprovable and potentially confusing without live witnesses, the Court concluded the judge did not abuse discretion and reversed the appellate court’s decision vacating the death sentences.
Real world impact
The decision keeps these death sentences in place and confirms that federal trial judges control how to question jurors about publicity. It also affirms that judges may exclude third‑party crime allegations at capital sentencing when the evidence is uncorroborated or would spur confusing mini‑trials. This ruling affects high‑profile federal trials and how defense teams present mitigation evidence.
Dissents or concurrances
A dissent argued the Waltham evidence should have been admitted and would have required a new sentencing proceeding; one concurring opinion questioned courts of appeals’ supervisory rulemaking.
