MOTION FOR DISCOVERY

NOW COMES the Defendant, [DEFENDANT FULL NAME], by and through undersigned counsel, and under Wis. Stat. § 971.23 and the Fourteenth Amendment as applied in Brady v. Maryland, 373 U.S. 83 (1963), Giglio v. United States, 405 U.S. 150 (1972), and Kyles v. Whitley, 514 U.S. 419 (1995), moves for an order requiring disclosure of the material identified below to the extent required by those authorities or specifically ordered by this Court.


Constitutional Basis

Brady v. Maryland Obligations

The prosecution must disclose evidence favorable to the accused when material to guilt or punishment. Brady v. Maryland, 373 U.S. 83, 87 (1963). The prosecutor must learn of favorable evidence known to others acting on the government's behalf in the case, including police. Kyles v. Whitley, 514 U.S. 419, 437 (1995).

Giglio v. United States Obligations

Nondisclosure of evidence affecting a key witness's credibility can violate the disclosure duty when material. Giglio v. United States, 405 U.S. 150, 154 (1972).


State Discovery Rule

On demand, Wis. Stat. § 971.23(1) requires the prosecutor to disclose covered material within a reasonable time before trial, subject to the statute's limits:

§ 971.23(1) — Prosecution Disclosure:

  • (1)(a): Defendant's written or recorded statements concerning the alleged crime;
  • (1)(b): A written summary of the defendant's oral statements that the prosecutor plans to use at trial;
  • (1)(c): Criminal record of the defendant;
  • (1)(d): Names and addresses of prosecution trial witnesses, subject to the rebuttal and impeachment exceptions;
  • (1)(e): Relevant written or recorded statements of listed witnesses, expert reports or summaries, and specified examination and test results the prosecutor intends to offer at trial;
  • (1)(f): Criminal records of prosecution witnesses known to the prosecutor;
  • (1)(g): Physical evidence the prosecutor intends to offer at trial;
  • (1)(h): Any exculpatory evidence.

Witness statements: Relevant written or recorded statements of listed prosecution witnesses are covered by the pretrial disclosure duty in § 971.23(1)(e).

The duty is limited by the terms of each paragraph and the State's possession, custody, or control. Under § 971.23(6), the Court may restrict, defer, or condition discovery by protective order. The requests below include some material outside automatic disclosure; Defendant asks for that material only if an identified statutory or constitutional duty applies or the Court finds a case-specific basis for production.

Legal authority

  • Wis. Stat. § 971.23 (Discovery and Inspection)
  • Brady v. Maryland, 373 U.S. 83 (1963)
  • Giglio v. United States, 405 U.S. 150 (1972)
  • Kyles v. Whitley, 514 U.S. 419 (1995)

Criminal law paperwork covers every stage of a criminal case, from the first appearance and bail motion through pretrial motions, plea agreements, sentencing, and appeals. Deadlines in criminal cases are short and often unforgiving, and constitutional rights can be waived just by missing a filing. Using the right motion at the right time can mean the difference between evidence getting suppressed, charges getting reduced, or a case getting dismissed entirely.
