A lawsuit by a critic of Maricopa County Sheriff Joe Arpaio over the critic's disorderly conduct and trespassing arrest in 2008 was dismissed on the day the trial was to start.
U.S. District Judge District Roslyn Silver says in an order Tuesday that Randy Parraz was dismissing the case.
Parraz didn't return a call seeking comment.
The lawsuit alleged Parraz was maliciously prosecuted on trumped up charges after a spat with sheriff's deputies over whether he had a right to be on public property during a county Board of Supervisors meeting. A judge dismissed the charges.
Parraz was a leader in the unsuccessful effort earlier this year to force a recall election against Arpaio.
Arpaio says Parraz must have figured a jury would have seen through his allegations.
