Lack of personal knowledge. A witness may not testify to a matter unless evidence is introduced sufficient to support a finding that the witness has personal knowledge of the matter.

Oath or affirmation. 906.03(1)(1) Before testifying, every witness shall be required to declare that the witness will testify truthfully, by oath or affirmation administered in a form calculated to awaken the witness's conscience and impress the witness's mind with the witness's duty to do so.
906.03(2)
(2) The oath may be administered substantially in the following form: Do you solemnly swear that the testimony you shall give in this matter shall be the truth, the whole truth and nothing but the truth, so help you God.
906.03(3)
(3) Every person who shall declare that the person has conscientious scruples against taking the oath, or swearing in the usual form, shall make a solemn declaration or affirmation, which may be in the following form: Do you solemnly, sincerely and truly declare and affirm that the testimony you shall give in this matter shall be the truth, the whole truth and nothing but the truth; and this you do under the pains and penalties of perjury.
906.03(4)

History: Sup. Ct. Order, 59 W (2d) R1, R163 (1973).
906.06
906.06
Competency of juror as witness. 906.06(1)
(1)
At the trial. A member of the jury may not testify as a witness before that jury in the trial of the case in which the member is sitting as a juror. If the juror is called so to testify, the opposing party shall be afforded an opportunity to object out of the presence of the jury.
906.06(2)
(2) Inquiry into validity of verdict or indictment. Upon an inquiry into the validity of a verdict or indictment, a juror may not testify as to any matter or statement occurring during the course of the jury's deliberations or to the effect of anything upon the juror's or any other juror's mind or emotions as influencing the juror to assent to or dissent from the verdict or indictment or concerning the juror's mental processes in connection therewith, except that a juror may testify on the question whether extraneous prejudicial information was improperly brought to the jury's attention or whether any outside influence was improperly brought to bear upon any juror. Nor may the juror's affidavit or evidence of any statement by the juror concerning a matter about which the juror would be precluded from testifying be received.
906.06 History
History: Sup. Ct. Order, 59 W (2d) R1, R165 (1973);
1991 a. 32.
906.06 Annotation
Defendant's failure to have evidence excluded under rulings of court, operates as a waiver. Sub. (2) cited. State v. Frizzell, 64 W (2d) 480, 219 NW (2d) 390.
906.06 Annotation
Impeachment of verdict through juror affidavits or testimony discussed. After Hour Welding v. Lanceil Management Co. 108 W (2d) 734, 324 NW (2d) 686 (1982).
906.06 Annotation
There was probable prejudice where question of depraved mind was central and juror went to jury room with dictionary definition of "depraved" written on card. State v. Ott, 111 W (2d) 691, 331 NW (2d) 629 (Ct. App. 1983).
906.06 Annotation
Conviction was reversed where extraneous information improperly brought to jury's attention raised reasonable possibility that error had prejudicial effect on hypothetical average jury. State v. Poh, 116 W (2d) 510, 343 NW (2d) 108 (1984).
906.06 Annotation
Evidence of juror's racially-prejudiced remark during jury deliberations was not competent under (2). Three-step procedure for impeachment of jury verdict discussed. State v. Shillcutt, 119 W (2d) 788, 350 NW (2d) 686 (1984).
906.06 Annotation
In any jury trial, material prejudice on the part of any juror impairs the right to a jury trial. That prejudicial material was brought to only one juror's attention and was not communicated to any other jurors is irrelevant to determining whether that information was "improperly brought to the jury's attention" under sub. (2). Castenada v. Pederson, 185 W (2d) 200, 518 NW (2d) 246 (1994), State v. Messelt, 185 W (2d) 255, 518 NW (2d) 232 (1994).
906.06 Annotation
Extraneous information is information, other than the general wisdom a juror is expected to possess, which a juror obtains from a non-evidentiary source. A juror who consciously brings non-evidentiary objects to show the other jurors improperly brings extraneous information before the jury. State v. Eison, 188 W (2d) 298, 525 NW (2d) 91 (Ct. App. 1994).
906.06 Annotation
Sub. (2) does not limit the testimony of a juror regarding clerical errors in a verdict; a written verdict not reflecting the jury's oral decision may be impeached by showing in a timely manner and beyond a reasonable doubt that all jurors are in agreement that an error was made. State v. Williquette, 190 W (2d) 678, 526 NW (2d) 144 (Ct. App. 1995).
906.06 Annotation
Analytical framework to be used to determine whether a new trial on the grounds of prejudice due to extraneous juror information outlined. State v. Eison, 194 W (2d) 160, 533 NW (2d) 738 (1995).
906.06 Annotation
Jurors may rely on their common sense and life experience during deliberations, including expertise a juror may have on a particular subject. That a juror was a pharmacist did not make his knowledge about the particular effect of a drug extraneous information subject to inquiry under sub. (2). State v. Heitkemper, 196 W (2d) 218, 538 NW (2d) 561 (Ct. App. 1995).
906.06 Annotation
The extraneous information exception under sub. (2) is not limited to factual information but also includes legal information obtained outside the proceeding. State v. Wulff, 200 W (2d) 318, 546 NW (2d) 522 (Ct. App. 1996).
906.06 Annotation
Generally, the sole area jurors are competent to testify to is whether extraneous information was considered. Except where juror bias goes to a fundamental issue such as religion, evidence of juror perceptions is not competent, no matter how mistaken, and cannot form the basis for granting a new trial. Anderson v. Burnett County, 207 W (2d) 585, 558 NW (2d) 636 (Ct. App. 1996).
906.06 Annotation
The trial court, and not the defendant or the defendant's attorney, is permitted to question a juror directly at a hearing regarding juror bias. The trial court's discretion in submitting questions suggested by the defendant is limited, but the failure to submit questions is subject to an harmless error evaluation. State v. Delgado, 215 W (2d) 16, 572 NW (2d) 479 (Ct. App. 1997).
906.06 Annotation
It was reasonable to refuse to allow a former member of the jury from testifying as a witness in the same case. Broadhead v. State Farm Mutual Insurance Co. 217 W (2d) 231, 579 NW (2d) 761 (Ct. App. 1998).
906.07
906.07
Who may impeach. The credibility of a witness may be attacked by any party, including the party calling the witness.
906.07 History
History: Sup. Ct. Order, 59 W (2d) R1, R169 (1973);
1991 a. 32.
906.08
906.08
Evidence of character and conduct of witness. 906.08(1)(1)
Opinion and reputation evidence of character. Except as provided in
s. 972.11 (2), the credibility of a witness may be attacked or supported by evidence in the form of reputation or opinion, but subject to the following limitations:
906.08(1)(a)
(a) The evidence may refer only to character for truthfulness or untruthfulness.
906.08(1)(b)
(b) Except with respect to an accused who testifies in his or her own behalf, evidence of truthful character is admissible only after the character of the witness for truthfulness has been attacked by opinion or reputation evidence or otherwise.
