In an interesting twist in the 2014 case filed against two Tucson officers for wrongful arrest, an appeals court has upheld the officers' arrest of a man who refused to show the officers his driver's license. A district court had initially ruled that the suit could continue. However, on appeal, the court determined the officers are immune from liability as the arrest was based on probable cause.
What happened in this case is rather complex, and whether this result will be appealed is still undetermined.
