No evidence seized under a search warrant shall be suppressed because of technical irregularities not affecting the substantial rights of the defendant.

The incorrect identification of a building’s address in a warrant was a technical error and did not render the resulting search unreasonable when the search made was of the building identified by the informant, which was otherwise correctly identified in the warrant. State v. Nicholson, 174 Wis. 2d 542, 497 N.W.2d 791 (Ct. App. 1993).

Mistakes on the face of a warrant were a technical irregularity under this section and the warrant met the 4th amendment standard of reasonableness when although the warrant identified the car to be searched incorrectly two times, the executing officer attached and incorporated an affidavit that correctly identified the car 3 times, describing the correct color, make, model, and style of the car along with the correct license plate, and the information was based on the executing officer’s personal knowledge from prior encounters. State v. Rogers, 2008 WI App 176, 315 Wis. 2d 60, 762 N.W.2d 795, 07-1850.
