Wisconsin has a statute which codifies the right of officers to make Terry stops:
968.24 Temporary questioning without arrest. After having identified himself or herself as a law enforcementofficer, a law enforcement officer may stop a person in a public place for a reasonable period of time when the officer reasonably suspects that such person is committing, is about to commit or has committed a crime, and may demand the name and address of the person and an explanation of the person’s conduct. Such
detention and temporary questioning shall be conducted in the vicinity where the person was stopped.
Unlike Nev. Rev. Stat. § 171. 123, however, § 968.24 does not impose an obligation upon the person stopped to identify himself.
This is a critical distinction.
The Wisconsin Supreme Court has held that mere refusal to identify oneself following a Terry stop does not constitute obstructing under § 946.41, Wis. Stats. Henes v. Morrissey, 194 Wis.2d 338, 354, 533 N.W.2d 802, 808 (1995): “Mere silence,
standing alone, is insufficient to constitute obstruction under the statute.”
At present, it appears that the only statutory authority that comes close to the Nevada Statute that was critical in Hiibel is § 343.18, Wis. Stats., which states in part:
343.18 License to be carried; verification of signature.
(1) Every licensee shall have his or her license document, including any special restrictions cards issued
under s. 343.10(7)(d) or 343.17(4), in his or her immediate possession at all times when operating a motor
vehicle and shall display the same upon demand from any judge, justice or traffic officer.
(1m) A person charged with violating sub. (1) may not be convicted if he or she produces in court or
in the office of the arresting officer a license theretofore issued to the licensee and valid at the time of his or her
arrest.
(2) For the purpose of verifying the signature on a license, any judge, justice or traffic officer may
require the licensee to write the licensee’s signature in the presence of such officer.
To invoke 343.18, an officer needs only probable cause to believe that the subject has been operating a motor vehicle and a
lawful reason to ask to see the license, which could result from reasonable suspicion that the person has violated a traffic regulation
or other law, exercise of a “community caretaker function.” 4, or a lawful “checkpoint” stop.
It is important to avoid misplaced reliance on Hiibel. An arrest without probable cause to believe an offense 5 has been committed clearly violates the Fourth Amendment. Hiibel cannot be relied upon as protection against Fourth Amendment claims unless there is a constitutionally defendable statute or ordinance that requires that a person identify himself upon request by an officer.
