906.10 History History: Sup. Ct. Order, 59 Wis. 2d R1, R184 (1973); 1991 a. 32.
906.11 906.11 Mode and order of interrogation and presentation.
906.11(1)(1)Control by judge. The judge shall exercise reasonable control over the mode and order of interrogating witnesses and presenting evidence so as to do all of the following:
906.11(1)(a) (a) Make the interrogation and presentation effective for the ascertainment of the truth.
906.11(1)(b) (b) Avoid needless consumption of time.
906.11(1)(c) (c) Protect witnesses from harassment or undue embarrassment.
906.11(2) (2) Scope of cross-examination. A witness may be cross-examined on any matter relevant to any issue in the case, including credibility. In the interests of justice, the judge may limit cross-examination with respect to matters not testified to on direct examination.
906.11(3) (3) Leading questions. Leading questions should not be used on the direct examination of a witness except as may be necessary to develop the witness's testimony. Ordinarily leading questions should be permitted on cross-examination. In civil cases, a party is entitled to call an adverse party or witness identified with the adverse party and interrogate by leading questions.
906.11 History History: Sup. Ct. Order, 59 Wis. 2d R1, R185 (1973); 1991 a. 32; 1999 a. 85.
906.11 Annotation A question is not leading if it merely suggests a subject rather than a specific answer that may not be true. Hicks v. State, 47 Wis. 2d 38, 176 N.W.2d 386 (1970).
906.11 Annotation It is error for a trial court to restrict cross-examination of an accomplice who was granted immunity, but the conviction will not be reversed if the error was harmless. State v. Schenk, 53 Wis. 2d 327, 193 N.W.2d 26 (1972).
906.11 Annotation A defendant who testifies in the defendant's own behalf may be recalled for further cross-examination to lay a foundation for impeachment. Evidence that on a prior occasion the defendant did not wear glasses and that the defendant had a gun similar to that described by the complainant was admissible when it contradicted the defendant's earlier testimony. Parham v. State, 53 Wis. 2d 458, 192 N.W.2d 838 (1972).
906.11 Annotation A trial judge should not have stricken the entire testimony of a defense witness for refusal to answer questions bearing on the witness's credibility that had little to do with the guilt or innocence of the defendant. State v. Monsoor, 56 Wis. 2d 689, 203 N.W.2d 20 (1973).
906.11 Annotation A trial judge's admonitions to an expert witness did not give the appearance of judicial partisanship requiring a new trial. Peeples v. Sargent, 77 Wis. 2d 612, 253 N.W.2d 459 (1977).
906.11 Annotation The extent, manner, and right of multiple cross-examinations by different counsel representing the same party can be controlled by the trial court. Hochgurtel v. San Felippo, 78 Wis. 2d 70, 253 N.W.2d 526 (1977).
906.11 Annotation A defendant has no right to be actively represented in court both personally and by counsel. Moore v. State, 83 Wis. 2d 285, 265 N.W.2d 540 (1978).
906.11 Annotation Leading questions were properly used to refresh a witness's memory. Jordan v. State, 93 Wis. 2d 449, 287 N.W.2d 509 (1980).
906.11 Annotation By testifying to his actions on the day a murder was committed, the defendant waived the self-incrimination privilege on cross-examination as to previous actions reasonably related to the direct examination. Neely v. State, 97 Wis. 2d 38, 292 N.W.2d 859 (1980).
906.11 Annotation Under the facts of this case, the trial judge's last minute determination to a witness to testify by telephone was an abuse of discretion, which deprived the defendant of the opportunity to have a meaningful cross-examination of the witness. Town of Geneva v. Tills, 129 Wis. 2d 167, 384 N.W.2d 701 (1986).
906.11 Annotation Discussing the use of leading questions in direct examination of a child. State v. Barnes, 203 Wis. 2d 132, 552 N.W.2d 857 (Ct. App. 1996), 95-1831.
906.11 Annotation A chart prepared by the prosecutor during a trial, in the jury's presence, to categorize testimony was not a summary under s. 910.06 but was a “pedagogical device" admissible within the court's discretion under this section. State v. Olson, 217 Wis. 2d 730, 579 N.W.2d 802 (Ct. App. 1998), 96-2142.
906.11 Annotation The rule of completeness for oral statements is encompassed within this section. A party's use of an out-of-court statement to show an inconsistency does not automatically give the opposing party the right to introduce the whole statement. Under the rule of completeness, the court has discretion to admit only those statements necessary to provide context and prevent distortion. State v. Eugenio, 219 Wis. 2d 391, 579 N.W.2d 642 (1998), 96-1394.
906.11 Annotation There was no misuse of discretion in allowing a three-year-old child witness to sit on her grandmother's lap while testifying regarding an alleged sexual assault. The trial court has the power to alter courtroom procedures in order to protect the emotional well-being of a child witness and is not required to determine that a child is unable to testify unless accommodations are provided. State v. Shanks, 2002 WI App 93, 253 Wis. 2d 600, 644 N.W.2d 275, 01-1372.
906.11 Annotation While sub. (1) provides the circuit court with broad discretion to control the presentation of evidence at trial, that discretion is not unfettered and must give way when the exercise of discretion runs afoul of other statutory provisions that are not discretionary. State v. Smith, 2002 WI App 118, 254 Wis. 2d 654, 648 N.W.2d 15, 01-1662.
906.11 Annotation Whether the trial court erroneously exercised its discretion under sub. (1) (a) to exercise reasonable control over the mode and order of interrogating witnesses and presenting evidence so as to make the interrogation and presentation effective for the ascertainment of the truth must be determined based upon the particular facts and circumstances of each individual case. The discovery provisions of s. 971.23 do not trump the trial court's ability to exercise its discretion to grant a continuance order. State v. Wright, 2003 WI App 252, 268 Wis. 2d 694, 673 N.W.2d 386, 03-0238.
906.11 Annotation Under the circumstances of this case, when the defendant sought to introduce evidence of prior specific instances of violence within the defendant's knowledge at the time of the incident in support of a self-defense claim, the circuit court had the authority under this section, in conjunction with s. 901.04 (3) (d), to order the defendant to disclose prior to trial any specific acts that the defendant knew about at the time of the incident and that the defendant intended to offer as evidence so that admissibility determinations could be made prior to trial. State v. McClaren, 2009 WI 69, 318 Wis. 2d 261, 767 N.W.2d 550, 07-2382.
906.11 Annotation There is no blanket rule barring or limiting the admission of the type of evidence that linked the cartridge case and bullet to the gun in this case. The admission and scope of such evidence is left to the reasonable discretion of the trial courts to exercise under this section and s. 904.03 and to cross-examination by adversary counsel. State v. Jones, 2010 WI App 133, 329 Wis. 2d 498, 791 N.W.2d 390, 09-2835.
906.12 906.12 Writing used to refresh memory. If a witness uses a writing to refresh the witness's memory for the purpose of testifying, either before or while testifying, an adverse party is entitled to have it produced at the hearing, to inspect it, to cross-examine the witness thereon, and to introduce in evidence those portions which relate to the testimony of the witness. If it is claimed that the writing contains matters not related to the subject matter of the testimony, the judge shall examine the writing in camera, excise any portions not so related, and order delivery of the remainder to the party entitled thereto. Any portion withheld over objections shall be preserved and made available to the appellate court in the event of an appeal. If a writing is not produced or delivered pursuant to order under this rule, the judge shall make any order justice requires, except that in criminal cases when the prosecution elects not to comply, the order shall be one striking the testimony or, if the judge in the judge's discretion determines that the interests of justice so require, declaring a mistrial.
906.12 History History: Sup. Ct. Order, 59 Wis. 2d R1, R193 (1973); 1991 a. 32.
906.13 906.13 Prior statements of witnesses.
906.13(1)(1)Examining witness concerning prior statement. In examining a witness concerning a prior statement made by the witness, whether written or not, the statement need not be shown or its contents disclosed to the witness at that time, but on request the same shall be shown or disclosed to opposing counsel upon the completion of that part of the examination.
906.13(2) (2) Extrinsic evidence of prior inconsistent statement of a witness.
906.13(2)(a)(a) Extrinsic evidence of a prior inconsistent statement by a witness is not admissible unless any of the following is applicable:
906.13(2)(a)1. 1. The witness was so examined while testifying as to give the witness an opportunity to explain or to deny the statement.
906.13(2)(a)2. 2. The witness has not been excused from giving further testimony in the action.
906.13(2)(a)3. 3. The interests of justice otherwise require.
906.13(2)(b) (b) Paragraph (a) does not apply to admissions of a party-opponent as defined in s. 908.01 (4) (b).
906.13 History History: Sup. Ct. Order, 59 Wis. 2d R1, R197 (1973); 1991 a. 32; 1999 a. 85.
906.13 Annotation A witness for the defense could be impeached by prior inconsistent statements to the district attorney even though made in the course of plea bargaining as to a related offense. Taylor v. State, 52 Wis. 2d 453, 190 N.W.2d 208 (1971).
906.13 Annotation A statement by a defendant, not admissible as part of the prosecution's case because it was taken without the presence of the defendant's counsel, may be used on cross-examination for impeachment if the statement is trustworthy. Wold v. State, 57 Wis. 2d 344, 204 N.W.2d 482 (1973).
906.13 Annotation A bright line test for determining whether a defendant's prior inconsistent statement is admissible for impeachment is whether it was compelled. State v. Pickett, 150 Wis. 2d 720, 442 N.W.2d 509 (Ct. App. 1989).
906.13 Annotation This section is applicable in criminal cases. A defense investigator's reports of witness interviews are statements under sub. (1) but only must be disclosed if defense counsel has examined the witness concerning the statements made to the investigator. State v. Hereford, 195 Wis. 2d 1054, 537 N.W.2d 62 (Ct. App. 1995), 94-1596.
906.13 Annotation A prior inconsistent statement is admissible under sub. (2) without first confronting the witness with that statement. Under sub. (2) (a) 2. and 3. extrinsic evidence of prior inconsistent statements is admissible if the witness has not been excused from giving further testimony in the case or if the interest of justice otherwise requires its admission. State v. Smith, 2002 WI App 118, 254 Wis. 2d 654, 648 N.W.2d 15, 01-1662.
906.14 906.14 Calling and interrogation of witnesses by judge.
906.14(1)(1)Calling by judge. The judge may, on the judge's own motion or at the suggestion of a party, call witnesses, and all parties are entitled to cross-examine witnesses thus called.
906.14(2) (2) Interrogation by judge. The judge may interrogate witnesses, whether called by the judge or by a party.
906.14(3) (3) Objections. Objections to the calling of witnesses by the judge or to interrogation by the judge may be made at the time or at the next available opportunity when the jury is not present.
906.14 History History: Sup. Ct. Order, 59 Wis. 2d R1, R200 (1973); 1991 a. 32.
906.14 Annotation A trial judge's elicitation of trial testimony is improper if the cumulative effect of the judge's questioning and direction of the course of the trial has a substantial prejudicial effect on the jury. Schultz v. State, 82 Wis. 2d 737, 264 N.W.2d 245 (1978).
906.14 Annotation The practice of judicial interrogation is a dangerous one but does not require that no court should be allowed to call and question a witness prior to completion of the presentation of evidence. State v. Carprue, 2004 WI 111, 274 Wis. 2d 656, 683 N.W.2d 31, 02-2781.
906.15 906.15 Exclusion of witnesses.
906.15(1)(1)At the request of a party, the judge or a circuit court commissioner shall order witnesses excluded so that they cannot hear the testimony of other witnesses. The judge or circuit court commissioner may also make the order of his or her own motion.
906.15(2) (2)Subsection (1) does not authorize exclusion of any of the following:
906.15(2)(a) (a) A party who is a natural person.
906.15(2)(b) (b) An officer or employee of a party which is not a natural person designated as its representative by its attorney.
906.15(2)(c) (c) A person whose presence is shown by a party to be essential to the presentation of the party's cause.
906.15(2)(d) (d) A victim, as defined in s. 950.02 (4), in a criminal case or a victim, as defined in s. 938.02 (20m), in a delinquency proceeding under ch. 938, unless the judge or circuit court commissioner finds that exclusion of the victim is necessary to provide a fair trial for the defendant or a fair fact-finding hearing for the juvenile. The presence of a victim during the testimony of other witnesses may not by itself be a basis for a finding that exclusion of the victim is necessary to provide a fair trial for the defendant or a fair fact-finding hearing for the juvenile.
906.15(3) (3)The judge or circuit court commissioner may direct that all excluded and non-excluded witnesses be kept separate until called and may prevent them from communicating with one another until they have been examined or the hearing is ended.
906.15 History History: Sup. Ct. Order, 59 Wis. 2d R1, R202 (1973); 1991 a. 32; 1997 a. 181; 2001 a. 61.
906.15 Annotation Under sub. (3), a circuit court has the authority to prevent an attorney from sharing with a nonparty witness who has yet to testify the testimony of prior witnesses during a recess, including barring a witness from reading a transcript of that testimony. State v. Copeland, 2011 WI App 28, 332 Wis. 2d 283, 798 N.W.2d 250, 08-2713.
906.16 906.16 Bias of witness. For the purpose of attacking the credibility of a witness, evidence of bias, prejudice, or interest of the witness for or against any party to the case is admissible.
906.16 History History: Sup. Ct. Order No. 16-02A, 2017 WI 92, 378 Wis. 2d xiii.
906.16 Note NOTE: Sup. Ct. Order No. 16-02A states that: “The Judicial Council Notes to Wis. Stats. §§ 901.07, 906.08, 906.09, and 906.16 are not adopted, but will be published and may be consulted for guidance in interpreting and applying the rule.”
906.16 Note Judicial Council Note, 2017:  This rule is adopted from the Uniform Rules of Evidence 616, which codifies United States v. Abel, 469 U.S. 45, 105 S. Ct. 465, 83 L.Ed.2d 450 (1984). The rule codifies the common law in Wisconsin . See State v. Long, 2002 WI App 114, ¶18, 255 Wis. 2d 729, 647 N.W.2d 884 (“Wisconsin law is in accordance with the principle set forth in Abel."). The committee viewed codification of the rule as useful, however, to reiterate that bias, prejudice, or interest of a witness is a fact of consequence under Wis. Stat. § 904.01. Further, the rule should make it clear that bias, prejudice, or interest is not a collateral matter, and can be established by extrinsic evidence. State v. Williamson, 84 Wis. 2d 370, 383, 267 N.W.2d 337, 343 (1978) (“The bias or prejudice of a witness is not a collateral issue and extrinsic evidence may be used to prove that a witness has a motive to testify falsely. . . . The extent of the inquiry with respect to bias is a matter within the discretion of the trial court.").
2021-22 Wisconsin Statutes updated through 2023 Wis. Act 240 and through all Supreme Court and Controlled Substances Board Orders filed before and in effect on May 30, 2024. Published and certified under s. 35.18. Changes effective after May 30, 2024, are designated by NOTES. (Published 5-30-24)
