Andrew Hanson v. Colorado Department of Revenue, Division of Motor Vehicles

Summary

The court affirmed the revocation of Hanson's driver's license after he refused a blood-alcohol test. It held that, under the version of the revocation statute applicable here, probable cause concerns whether the officer had sufficient evidence to issue the revocation notice, not whether the officer's initial contact with the driver was lawful. It also held that the exclusionary rule generally does not apply in license-revocation proceedings and that the officer's conduct neither occurred in bad faith nor shocked the court's conscience. Justice Hood, dissenting, would have recognized a statutory right to challenge the warrantless home entry and would have remanded for further proceedings because Hanson lacked an opportunity to cross-examine the officer.
