The Supreme Court in the United States has on Friday reinstated the death sentence for convicted Boston Marathon bomber Dzhokhar Tsarnaev.

The justices, by a 6-3 vote, agreed with Biden administration's arguments that a federal appeals court was wrong to throw out the sentence of death a jury imposed on Tsarnaev for his role in the bombing that killed three people near the finish line of the marathon in 2013.

"Dzhokhar Tsarnaev committed heinous crimes. The Sixth Amendment nonetheless guaranteed him a fair trial before an impartial jury. He received one," Justice Clarence Thomas wrote for the majority, made up of the court's six conservative justices.

In dissent for the court's three liberal justices, Justice Stephen Breyer wrote, "In my view, the Court of Appeals acted lawfully in holding that the District Court should have allowed Dzhokhar to introduce this evidence.”

Breyer has called on the court to reconsider capital punishment. "I have written elsewhere about the problems inherent in a system that allows for the imposition of the death penalty. This case provides just one more example of some of those problems," he wrote.
