According to the agency, the judges will consider the appeal, which was filed during the administration of Donald Trump.
The message emphasizes that it is not yet known how the new administration of Joe Biden will react to the Tsarnaev case.
Initially, the prosecution and the decision to seek the death sentence was made under President Barack Obama, when Biden served as vice president.
On April 15, 2013, a terrorist attack was committed at the finish line of the Boston Marathon.
The explosion killed three people and injured more than 200.
Tsarnaev was sentenced to death in May 2015 by a jury.
In December 2018, his defense applied to the Court of Appeal with a request to overturn his death sentence, which was done.
Trump called this decision ridiculous.
In August 2020, the US Attorney General William Barr announced that he intends to obtain the death sentence for Dzhokhar Tsarnaev.
