717 Fed. Appx. 555 (6th Cir 2017): Sheriff’s deputies used a confidential informant to conduct drug buys and identify the participants, one of whom was bound over for trial at a preliminary exam. The charges were subsequently dismissed based on contradictory testimony from another participant and the fact that the plaintiff passed a polygraph test. He then sued Huron County and several deputies, claiming that his Fourth Amendment rights were violated in the drug buys. The trial court granted summary judgement to dismiss the case against the county and deputies, because the bind-over conclusively established that there was probable cause to arrest plaintiff on the charges. The Sixth Circuit Court of Appeals upheld the lower court’s dismissal of all claims against Defendants.
