State v. McMahon
In State v. McMahon, 186 Wis. 2d 68, 87, 519 N.W.2d 621 (Ct. App. 1994), the Court found that the judge's communications to the jury constituted error, but concluded that the error was harmless. See McMahon, 186 Wis. 2d at 88.
The Court concluded that the error was harmless because the communications "were not the product of some unilateral decision by the trial court about what to say to the jury," and that none of the communications considered substantive matters which would have been aided by the defendant's presence.
