In State v. North, 91 Wis. 2d 507, 283 N.W.2d 457 (Ct. App. 1979), the trial court apparently confused a misdemeanor charge with a felony charge when it sentenced North to two-and-one-half years on the misdemeanor and six months on the felony. North, 91 Wis. 2d at 509. Over three months later, the court realized its error, and reduced the misdemeanor sentence to the statutory maximum of six months and increased the felony sentence to two-and-one-half years. See id.
