On Point: d. Officer's mistake of law

In Heien v. North Carolina, SCOTUS held that an officer’s “reasonable” mistake of law can give rise to the reasonable suspicion needed to justify a traffic.  And SCOW followed suit in State v. Houghton. If you are researching this issue, you might want to take a look at this new case note in Harvard Law Review. The last few paragraphs, in particular, highlight areas for future litigation.

You’ve seen this before. An officer makes a traffic stop based on a “misunderstanding” of the law, then conducts a search and finds incriminating evidence.  Last July, in State v. Antonio Brown, SCOW held that a seizure based on such a mistake violates the 4th Amendment. Six months later, SCOTUS reached the opposite result in Heien v. North Carolina. In this case, SCOW overturns Brown to hold that: (1) “pretextual stops . . . are not per se unreasonable under the 4th Amendment”; (2) probable cause is never required for a traffic stop; (3) the officer here “misunderstood” multiple provisions of Ch. 346, but his mistakes were “objectively reasonable”; and (4) Article I §11 of Wisconsin’s Constitution extends no further than the 4th Amendment.

Review of an unpublished per curiam court of appeals decision; case activity

Issue (composed by On Point)

Can a police officer’s reasonable mistake of law give rise to reasonable suspicion or probable cause necessary to uphold a seizure under article I, §11 of the Wisconsin constitution?

State v. Christopher M. Repenshek, 2004 WI App 229, PFR filed 12/17/04
For Repenshek: Stephen E. Mays

Issue/Holding: The test for probable cause is purely objective, so that the arresting officer’s intent to arrest for a crime that is in fact non-existent is irrelevant. Because in Repenshek’s instance probable cause to arrest indisputably existed, his arrest was not illegal even though the officer thought he was arresting Repenshek for a crime that,

State v. Michael M. Longcore (I), 226 Wis. 2d 1, 594 N.W.2d 412 (Ct. App. 1999), affirmed by equally divided vote, 2000 WI 23, 233 Wis. 2d 278, 607 N.W.2d 620
For Longcore: William E. Schmaal, SPD, Madison Appellate.

Issue/Holding: An officer stopped Longcore’s car because his back window had been replaced with a plastic covering. The trial court ruled that this was a permissible temporary stop but the court of appeals holds that the officer wasn’t conducting a temporary,
