U.S. Magistrate Judge J. Kelley Arnold on Monday found Wayne Johnson and Andy Noel guilty after the pair waived their right to a jury trial and admitted their roles.
The two were convicted of conspiracy to violate the Marine Mammal Protection Act and unlawfully taking a marine mammal.
Defense attorneys say their clients agreed to waive the jury trial so they could get on with appealing some of the rulings made in the case, including one in which Arnold determined their actions were not protected under the First Amendment right to religious freedom.
He also had denied their motions to dismiss the charges based on the Makah tribe's treaty rights to hunt whales.
"There was no reason to go through a several-day jury trial when the jury wasn't going to be able to hear their defense," said Jack Fiander, Noel's attorney.
