State v. Hansford
In State v. Hansford, 219 Wis. 2d 226, 580 N.W.2d 171 (1998), the supreme court concluded that, under art. I, 7 of the Wisconsin Constitution and four Wisconsin Supreme Court decisions, "the right to a 12-person jury extends to all criminal defendants, regardless of whether they are charged with misdemeanor or felony offenses." Hansford, 219 Wis. 2d at 241.
In Hansford, the defendant had objected to the six-person jury in his case, specifically contending that the six-person misdemeanor jury statute was unconstitutional under art. I, 7 of the Wisconsin Constitution. Hansford, 219 Wis. 2d at 232.
Concluding that the defendant was correct, the supreme court reversed his conviction. Id. at 243.
