1. Introduction

Defendant [DEFENDANT NAME] (“Defendant”) respectfully moves this Court, pursuant to Wis. Stat. § 971.31, the Fourth Amendment to the United States Constitution, and Article I, § 11 of the Wisconsin Constitution, to suppress all physical evidence, statements, observations, and fruits thereof obtained as a result of the unlawful [search/seizure] conducted on [DATE] at [LOCATION].

2. Procedural Posture

  1. On [DATE], the State filed a Criminal Complaint charging Defendant with [LIST CHARGES] arising from the incident of [DATE].
  2. Defendant was arraigned on [DATE] and entered pleas of not guilty.
  3. Discovery produced on [DATE] reveals that the evidence at issue was obtained through [briefly describe search/seizure].
  4. This Motion is timely under Wis. Stat. § 971.31(5)(a) and the Court’s [DATE] scheduling order.

3. Statement of Facts

[Provide a concise, chronologically-ordered narrative of all facts relevant to the challenged search or seizure. Identify:
• law-enforcement agency and officers involved;
• time, date, and location;
• whether a warrant was issued (include warrant number, issuing court, and time signed);
• manner in which warrant was executed or search conducted;
• items seized;
• Defendant’s contemporaneous statements or conduct;
• any subsequent searches dependent on the first search.]

4. Applicable Law

4.1 Constitutional Framework

  1. The Fourth Amendment guarantees the right of the people to be secure against unreasonable searches and seizures. U.S. Const. amend. IV.
  2. Article I, § 11 of the Wisconsin Constitution affords co-extensive protections.

4.2 Wisconsin Statutory Framework

  1. Warrants, execution of warrants, and related procedures are governed by Wis. Stat. §§ 968.10–968.22.
  2. Motions to suppress evidence must be raised before trial under Wis. Stat. § 971.31(2), within the time limits set by § 971.31(5)(a)–(b), or the objection is deemed waived (subject to the court's discretion to entertain the motion at trial with waiver of jeopardy).
  3. The exclusionary rule bars the admission of evidence obtained in violation of constitutional or statutory search-and-seizure provisions.
  4. An order denying a motion to suppress may be reviewed on appeal from a final judgment or order, even where the judgment was entered on a plea of guilty or no contest. Wis. Stat. § 971.31(10).

4.3 Suppression Standard & Burdens

  1. The State bears the burden of proving by a preponderance of the evidence that the search or seizure was lawful.
  2. Once the Defendant makes a prima facie showing of illegality, the burden shifts to the State to justify the intrusion under a recognized exception.

4.4 Good-Faith Exception

  1. Wisconsin recognizes a good-faith exception to the exclusionary rule, but it is narrower than the federal rule under United States v. Leon, 468 U.S. 897 (1984). In State v. Eason, 2001 WI 98, 245 Wis. 2d 206, 629 N.W.2d 625, the Wisconsin Supreme Court held that Article I, Section 11 of the Wisconsin Constitution requires the State to satisfy the federal Leon test and to make an additional showing before the exception applies: that the process used in obtaining the search warrant included (a) a significant investigation, and (b) a review by either a police officer trained and knowledgeable in the requirements of probable cause and reasonable suspicion, or a knowledgeable government attorney.
  2. The State bears the burden of establishing applicability of the exception. Under Leon, the exception does not apply where (a) the warrant is based on knowingly or recklessly false information, (b) the issuing court wholly abandons its neutral role, (c) the affidavit is so lacking in probable cause that belief in its existence is objectively unreasonable, or (d) the warrant is so facially deficient that officers cannot reasonably presume it to be valid.
  3. Even where the Leon factors do not independently defeat good faith, Wisconsin's additional Eason requirements are independently fatal to the State's showing where the record does not reflect a significant investigation or a qualified pre-application legal review. See State v. Marquardt, 2005 WI 157, 286 Wis. 2d 204, 705 N.W.2d 878 (a "significant investigation" is not established merely by the number of officers or hours devoted to the case).

5. Argument

5.1 Defective Warrant / Warrantless Search

[Analyze why no valid warrant existed or why the warrant was deficient—probable cause, particularity, staleness, jurisdictional defect, absence of oath, etc.]

5.2 No Applicable Exception to the Warrant Requirement

[Address and negate each potential exception raised by the State: consent, exigent circumstances, search-incident-to-arrest, automobile exception, plain view, protective sweep, inventory search, community-caretaker, etc.]

5.3 Evidence Must Be Suppressed

  1. Because the search violated Defendant’s constitutional and statutory rights, the fruits of that search are inadmissible.
  2. Suppression must extend to all direct and derivative evidence, including but not limited to:
    a. [ITEM 1];
    b. [ITEM 2];
    c. [STATEMENTS];
    d. Any additional evidence discovered via subsequent searches dependent on the original illegality (fruit of the poisonous tree doctrine).

6. Request for Evidentiary Hearing

Pursuant to Wis. Stat. § 971.31(3)–(4), Defendant requests an evidentiary hearing to (a) permit cross-examination of officers, (b) test the sufficiency and veracity of the affidavit — including, if a substantial preliminary showing of a knowing or reckless false statement is made, a hearing under Franks v. Delaware, 438 U.S. 154 (1978) — and (c) develop the factual record required for adjudication of this Motion.

7. Relief Requested

Defendant respectfully asks that the Court:

  1. Conduct an evidentiary hearing;
  2. Suppress all evidence obtained as a result of the unconstitutional [search/seizure] described herein;
  3. Suppress all derivative evidence; and
  4. Grant such further relief as the Court deems just and proper.

8. Conclusion

For the foregoing reasons, the Court should suppress the challenged evidence in its entirety.


9. Certification of Compliance

I certify that this Motion:

  1. Complies with Wis. Stat. § 971.31 and any local rules;
  2. Is not interposed for improper purpose; and
  3. Is supported by existing law or a good-faith argument for extension, modification, or reversal of existing law.

  • U.S. Const. amend. IV
  • Wis. Stat. §§ 968.10–968.22 (Searches and Seizures; Search Warrants)
  • State v. Eason, 2001 WI 98, 245 Wis. 2d 206, 629 N.W.2d 625 (Wisconsin's good-faith exception; rejecting unqualified adoption of the federal Leon standard)
  • State v. Marquardt, 2005 WI 157, 286 Wis. 2d 204, 705 N.W.2d 878 (defining "significant investigation" under Eason)

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.
