The trial of marathon bombing suspect Dzhokhar Tsarnaev can begin as scheduled Monday in Boston after a federal appeals court ruled yesterday the defense had not met the ``extraordinary'' standard required to justify its intervention.

Tsarnaev's lawyer had asked the 1st U.S. Circuit Court of Appeals to delay the trial and move it out of Massachusetts, saying he couldn't get a fair trial in a place where so many were affected by the bombings.

The appeals court ruled 2-1 to avoid intervening in the trial's timing and location. One judge dissented, saying he didn't have enough time to carefully consider the petition filed Wednesday.

One of Tsarnaev's attorneys, Miriam Conrad, declined comment.

Tsarnaev has pleaded not guilty to 30 charges connected to the April 2013 explosions that killed three people and wounded more than 260 others. Some of the charges carry the death penalty.
