Sub. (2) does not conflict with the separation of powers doctrine and is constitutional. State v. Dums, 149 Wis. 2d 314, 440 N.W.2d 814 (Ct. App. 1989). A defendant is "charged" with a crime for purposes of sub. (2) (a) when a criminal complaint is filed. State v. Corvino, 2016 WI App 52, 370 Wis. 2d 681, 883 N.W.2d 169, 15-0584. The plain language of sub. (2) (a) clearly shows that the legislature intended to except operating while intoxicated (OWI) prosecutions from the general rule set forth in s. 971.29(1) allowing charges to be amended without court approval at any time prior to arraignment. State v. Corvino, 2016 WI App 52, 370 Wis. 2d 681, 883 N.W.2d 169, 15-0584.
