State v. Eichman

In State v. Eichman, 155 Wis. 2d 552, 456 N.W.2d 143 (Wis. 1990), the Wisconsin Supreme Court agreed that there is a distinction between "suppressing" evidence and "excluding" evidence, as the former generally bars admission of evidence at trial as a result of governmental misconduct, such as a constitutional violation, and the latter generally involves only a violation of the rules of evidence, but disagreed that the distinction between suppressing evidence and excluding evidence prohibits the State from appealing such pretrial rulings. 456 N.W.2d at 147.
