A federal judge Monday said the federal prosecutors' conduct was "outrageous" and "violated due process rights" of the defendants.  

U.S. District Judge Gloria Navarro said a new trial would not be sufficient to address the problems in the case and would provide the prosecution with an unfair advantage going forward. She dismissed the charges against the four men "with prejudice," meaning they cannot face trial again.  

As the courtroom doors opened after Navarro's ruling, a huge cheer went up from the crowd of spectators gathered outside.

Navarro's decision comes less than a month after she declared a mistrial in case and found that federal prosecutors willfully withheld critical and "potentially exculpatory" evidence from the defense.

Cliven Bundy, his sons Ammon and Ryan Bundy, and militia member Ryan Payne were all in court. Cliven Bundy had remained in jail until the hearing. The judge ordered his immediate release.
