NOTE: See also the notes to s. 906.06 for decisions relating to overturning verdicts due to juror misconduct.
Contradictory testimony of different state witnesses does not necessarily cancel the testimony and render it unfit as a basis for a conviction. The determination of credibility and the weight to be accorded the testimony is a jury function, and the jury may accept or reject the inconsistent testimony, even under the beyond a reasonable doubt burden of proof. Embry v. State, 46 Wis. 2d 151, 174 N.W.2d 521 (1970). A resident of Menominee County may properly be tried by a jury drawn from the Shawano-Menominee district. Article IV, section 23, is not violated by using district-based jury lists. Pamanet v. State, 49 Wis. 2d 501, 182 N.W.2d 459 (1971). When two alternate jurors in a murder trial made remarks critical of court procedures and the defense attorney, but were removed prior to the time the case was submitted to the jury, a showing of probable prejudice was required for a mistrial to be ordered. Shelton v. State, 50 Wis. 2d 43, 183 N.W.2d 87 (1971). Asking an improper question that is not answered is not grounds for reversal, especially when the trial court instructs the jury to disregard the question and to draw no inferences therefrom. The instruction is presumed to efface any possible prejudice resulting from asking the question. Taylor v. State, 52 Wis. 2d 453, 190 N.W.2d 208 (1971). The trial court did not err in failing to declare a mistrial because of a statement made by the prosecutor in closing argument, challenged as improper because the prosecutor expressed his opinion as to the defendant’s guilt, when it neither could be said that the statement was based on sources of information outside the record, nor expressed the prosecutor’s conviction as to what the evidence established. State v. McGee, 52 Wis. 2d 736, 190 N.W.2d 893 (1971). When the prosecutor stated in opening remarks that the defendant refused to be fingerprinted but failed to introduce testimony to this effect, the error was cured by proper instructions. State v. Tew, 54 Wis. 2d 361, 195 N.W.2d 615 (1972). Discussing the exclusion of young persons, students, and teachers from a jury list. If a challenge establishes discrimination, the jury list is invalid and the defendant need not show prejudice. Brown v. State, 58 Wis. 2d 158, 205 N.W.2d 566 (1973). Discussing rules for proving discrimination in compiling a jury list and the burden of proof. Wilson v. State, 59 Wis. 2d 269, 208 N.W.2d 134 (1973). Jurors are not necessarily prejudiced by reason of having sat as jurors at the same term on similar cases when the state’s witnesses are the same, but it is better not to use the same jurors. State v. Boutch, 60 Wis. 2d 397, 210 N.W.2d 751 (1973). The absence of persons of the defendant’s race on the jury panel is not ipso facto evidence of prejudice. Jones v. State, 66 Wis. 2d 105, 223 N.W.2d 889 (1974). A defendant, having been found competent to stand trial, must necessarily have possessed the intellectual capacity to waive the right to a jury trial. Norwood v. State, 74 Wis. 2d 343, 246 N.W.2d 801 (1976). A jury must unanimously find participation in a crime, but the jury need not unanimously agree whether a defendant: 1) directly committed the crime; 2) aided and abetted its commission; or 3) conspired with another to commit it. Holland v. State, 91 Wis. 2d 134, 280 N.W.2d 288 (1979). Excusing Native Americans from a jury without individual examination denied the Native American defendant a trial by an impartial jury. State v. Chosa, 108 Wis. 2d 392, 321 N.W.2d 280 (1982). The verdict was unanimous in a battery case even though the jury was not required to specify whether the battery occurred when the defendant threw an object at the victim or during an ensuing fistfight. State v. Giwosky, 109 Wis. 2d 446, 326 N.W.2d 232 (1982). The verdict was unanimous in a rape case even though the jury was not required to specify whether the sexual assault was vaginal or oral. State v. Lomagro, 113 Wis. 2d 582, 335 N.W.2d 583 (1983). When the accused refused to participate in the trial, the court erred by failing to inform the accused of the right to be present at trial, to waive that right, and to reclaim it at any time. State v. Haynes, 118 Wis. 2d 21, 345 N.W.2d 892 (Ct. App. 1984). A waiver of the right to a jury trial is effective if the defendant understands the basic purpose and function of a jury trial. Trial courts are prospectively ordered to advise defendants of the unanimity requirement before accepting a waiver. State v. Resio, 148 Wis. 2d 687, 436 N.W.2d 603 (1989). A defendant has the right to a jury determination on each element of a charged offense. The right can be waived only by the defendant personally on the record. State v. Villarreal, 153 Wis. 2d 323, 450 N.W.2d 519 (Ct. App. 1989). Once a defendant makes a prima facie showing that the prosecutor used peremptory challenges in a purposefully discriminatory manner, the burden shifts to the prosecution to provide a neutral explanation for challenging the jurors. Discussing Batson, 476 U.S. 79 (1986). State v. Walker, 154 Wis. 2d 158, 453 N.W.2d 127 (1990). Waiver of a jury trial must be made by the affirmative action of the defendant. Neither counsel nor the court may waive it on the defendant’s behalf. If the defendant has not personally waived the right, the proper remedy is a new trial, not a postconviction hearing. State v. Livingston, 159 Wis. 2d 561, 464 N.W.2d 839 (1991). Under rare circumstances, a jury instruction creating a conclusive presumption regarding an element of a crime may be harmless error. State v. Kuntz, 160 Wis. 2d 722, 467 N.W.2d 531 (1991). Kinship to a person who has been criminally charged or convicted may constitute a legitimate racially-neutral reason for striking a member of the jury panel. State v. Davidson, 166 Wis. 2d 35, 479 N.W.2d 181 (Ct. App. 1991). Discussing unanimity requirements when multiple occurrences of multiple acts are charged. State v. Marcum, 166 Wis. 2d 908, 480 N.W.2d 545 (Ct. App. 1992). A defendant cannot show jury prejudice unless the exhaustion of peremptory challenges left a jury that included an objectionable or incompetent member. State v. Traylor, 170 Wis. 2d 393, 489 N.W.2d 626 (Ct. App. 1992).
