If an arbitrator or court determines that evidence was obtained during an investigation of a peace officer concerning conduct that could result in punitive action in a manner which violates any provision of NRS 289.010 to 289.120, inclusive, and that such evidence may be prejudicial to the peace officer, such evidence is inadmissible and the arbitrator or court shall exclude such evidence during any administrative proceeding commenced or civil action filed against the peace officer. If the arbitrator or court further determines that such evidence was obtained by a law enforcement agency in bad faith, the arbitrator or court must dismiss the administrative proceeding or civil action with prejudice.
