Nuclear engineer Walt Tamosaitis says he was removed from his position because he brought up safety concerns.
Now a three-judge appeals court panel is considering the case of the well-known Hanford Nuclear Reservation whistleblower. Oral arguments happened Thursday.
Tamosaitis argues that he was pressured, demoted and then let go by his employer, a Hanford contractor called URS. This, after he questioned the safety of a massive factory being built to treat nuclear waste at the Hanford site.
In a full courtroom in downtown Seattle, lawyers argued back and forth over the technicalities of the case.
