Iowa Court of Appeals holds that Iowa Code section 321I.27 as applied is unconstitutional, for a statute cannot overrule the 4th Amendment or Article I section 8 of the Iowa constitution. An officer must have probable cause of a law violation in order to stop a vehicle. In this case, the stop of the Defendant’s utility vehicle (UTV) by a conservation officer, which was not supported by reasonable suspicion or probable cause, violated his constitutional rights—notwithstanding Iowa Code section 321I.27, which gives statutory authority for the stop.
