Unsealed court documents detail how the team of prosecutors tasked with convicting Cliven Bundy and his sons of crimes relating to a 2014 armed standoff failed to turn over potential exculpatory evidence to the court, The Oregonian reports.

The Bundys’ case ended in a mistrial Dec. 20 after Judge Gloria Navarro ruled that prosecutors violated the civil rights of the defendants by withholding evidence supporting the Bundys’ case. Navarro is considering dismissing the case “with prejudice” and blocking prosecutors from retrying the case. Her decision will come Jan. 8, according to The New York Times.

“There were approximately 3,000 pages that were provided to us only after we started trial,” Bundy lawyer Bret D. Whipple told TheNYT. “I personally have never seen anything like this, especially in a case of such importance.”

Those 3,000 pages include the Bundys’ requests for multiple federal assessments that showed the Bundy family was likely not dangerous. Prosecutors called the requests part of a “long list of frivolous and vexatious pleadings,” until a government witness, under cross examination, revealed knowledge of the assessments in court, The Oregonian reports. – READ MORE
