The U.S. Supreme Court on Friday reinstated convicted Boston Marathon bomber Dzhokhar Tsarnaev's death sentence for his role in the 2013 attack that killed three people and wounded more than 260 others, agreeing with the federal government.
In a 6-3 decision, the justices sided with the U.S. Justice Department's challenge to a 2020 federal appeals court ruling that had upheld Tsarnaev's conviction but overturned his death sentence.
The Supreme Court faulted the Boston-based First Circuit Court of Appeals on its findings both that Tsarnaev's right to a fair trial under the U.S. Constitution's Sixth Amendment was violated and that the trial judge wrongly excluded certain evidence about a separate crime.
"Dzhokhar Tsarnaev committed heinous crimes. The Sixth Amendment nonetheless guaranteed him a fair trial before an impartial jury. He received one," conservative U.S. Supreme Court Justice Clarence Thomas wrote for the majority.
The court's six conservative justices were in the majority, with its three liberals dissenting.
U.S. President Joe Biden as a candidate promised to work to pass legislation in Congress to eliminate the death penalty at the federal level and set incentives for states to do so as well, instead endorsing life sentences without probation or parole. But his administration last year opted to proceed with an appeal initially launched by the Justice Department under his predecessor, Donald Trump, to defend Tsarnaev's death sentence.
Lawyers for Tsarnaev, who is 28 now and was 19 at the time of the attack, have argued that Tsarnaev played a secondary role in the marathon bombing to his older brother, Tamerlan, whom they called "an authority figure" with "violent Islamic extremist beliefs."
Justice Department reviewing death penalty
Jurors convicted Dzhokhar Tsarnaev in 2015 on all 30 counts he faced and determined he deserved execution for a bomb he planted that killed Martin Richard, 8, and Chinese exchange student Lingzi Lu, 23. Restaurant manager Krystle Campbell, 29, was killed by a second bomb.
No federal inmates were executed for 17 years before Trump oversaw 13 executions in the last six months of his term.
U.S. Attorney General Merrick Garland imposed a moratorium last July on federal executions while the Justice Department reviews the death penalty.
White House press secretary Jen Psaki said Biden continues to have "grave concerns about whether capital punishment, as currently implemented, is consistent with the values that are fundamental to our sense of justice and fairness."

The Tsarnaev brothers detonated two homemade pressure-cooker bombs at the marathon's finish line on April 15, 2013, and days later killed a police officer. Tamerlan Tsarnaev, 26, died after a gunfight with police.
The appeals court found that U.S. District Judge George O'Toole, who presided over the trial, improperly excluded evidence relating to a 2011 triple murder in Waltham, Mass., linked to Dzhokhar Tsarnaev's older brother.
The primary source of the evidence about the other murders, a man named Ibragim Todashev, was killed by an FBI agent in 2013, when he attacked officers during an interview.
The appeals court also found that O'Toole "fell short" in screening jurors for potential bias following pervasive news coverage of the bombings.
