v.
[DEFENDANT FULL NAME] Defendant

Case No.: [CASE NUMBER]

MOTION TO SUPPRESS EVIDENCE

[DATE]


1. DOCUMENT HEADER

This Motion is submitted pursuant to Idaho Criminal Rule 12 (motions to suppress), Idaho Criminal Rule 41 (search and seizure), the Fourth Amendment to the United States Constitution, and article I, section 17 of the Idaho Constitution, requesting suppression of the identified evidence and any identified derivative item for which the facts and applicable law require exclusion.


2. DEFINITIONS

For purposes of this Motion, the following terms have the meanings indicated below.

2.1 “Subject Evidence” means the following directly challenged physical, testimonial, or electronic items: [IDENTIFY EACH ITEM]. “Claimed Derivative Evidence” means [IDENTIFY EACH ADDITIONAL ITEM AND EXPLAIN HOW THE CHALLENGED CONDUCT LED TO IT].

2.2 “Executing Officer” means [OFFICER NAME], badge no. [BADGE #], or any agent acting in concert with or at the direction of said officer.

2.3 “Warrant” means the document identified as Search Warrant No. [WARRANT #] issued on [DATE], including all supporting affidavits and returns.


3. INTRODUCTION AND RELIEF REQUESTED

Defendant, by and through undersigned counsel, moves this Court for an order suppressing the Subject Evidence on the grounds that:

  • The search and seizure violated the Fourth Amendment and article I, section 17;
  • The Warrant (if any) lacked probable cause or was facially deficient under Idaho Criminal Rule 41;
  • No valid exception to the warrant requirement applies; and
  • The State cannot rely on any federal "good-faith" exception to excuse the defect, because the Idaho Supreme Court has expressly declined to recognize such an exception under article I, section 17 of the Idaho Constitution. See State v. Guzman, 122 Idaho 981, 842 P.2d 660 (1992).

Accordingly, Defendant requests:
a. Suppression of the Subject Evidence;
b. Suppression of each identified derivative item for which Defendant establishes a causal and legal basis for exclusion, subject to any applicable limit;
c. An evidentiary hearing pursuant to Idaho Criminal Rule 12; and
d. Such other relief as the Court deems just and proper.


4. STATEMENT OF FACTS

4.1 On [DATE & TIME], Executing Officer initiated [TRAFFIC STOP / HOME ENTRY / OTHER] involving Defendant at [LOCATION].

4.2 Officers [DESCRIBE SEARCH OR SEIZURE]. The authorization, if any, was [IDENTIFY WARRANT OR EXPLAIN WHY NONE APPLIED]. They obtained:

  • Item 1: [DESCRIPTION]
  • Item 2: [DESCRIPTION]
  • Electronic data: [DEVICE AND DATA]

4.3 If challenging the Warrant affidavit, identify each claimed false statement or omission, the evidence of its falsity, the officer's knowledge or recklessness, and its effect on the probable-cause showing: [DETAILS OR N/A].

4.4 The facts bearing on any asserted consent, exigency, automobile exception, or other claimed basis for a warrantless search are [DETAILS OR N/A].

4.5 The claimed derivative item(s) and causal facts connecting each to the challenged conduct are [IDENTIFY ITEMS AND FACTS].


5. LEGAL STANDARDS

5.1 Constitutional Framework

The Fourth Amendment to the United States Constitution and article I, section 17 of the Idaho Constitution protect individuals from unreasonable searches and seizures. Whether a particular item must be excluded depends on the established violation, its connection to that violation, and any applicable limit on exclusion.

5.2 Idaho Suppression Rules

Idaho Criminal Rule 12(b)(3) requires an illegally obtained evidence suppression motion before trial, and Rule 12(c) requires enough detail about the evidence and legal basis to give the opposing party reasonable notice. Under Rule 12(d), file within 28 days after entry of a not-guilty plea or seven days before trial, whichever is earlier. In a felony case, bring the motion on for hearing within 14 days after filing or 48 hours before trial, whichever is earlier. The court may shorten or enlarge those periods and may relieve noncompliance for good cause or excusable neglect; Rule 12(f) otherwise treats a missed deadline as waiver, subject to relief for cause shown. Idaho Criminal Rule 41 governs the issuance, content, and execution of search warrants, including the probable-cause showing required under Rule 41(c) and the particularity and timing requirements of Rule 41(d). A warrantless search must fit an exception to the warrant requirement. Fletcher, No. 50707.

5.3 No Good-Faith Exception Under Idaho Law

Under article I, section 17 of the Idaho Constitution, Idaho rejects a good-faith exception to the exclusionary rule. State v. Guzman, 122 Idaho 981, 842 P.2d 660 (1992); see also State v. Fletcher, No. 50707 (Idaho June 27, 2025) (describing Guzman). An officer's good-faith reliance on a defective warrant does not by itself defeat a suppression claim under that provision. Analyze each item and any separate limit on exclusion, including inevitable discovery where supported by the evidence. State v. Campbell, No. 49269 (Idaho Mar. 26, 2026) (substitute opinion).


6. ARGUMENT

6.1 Lack of Probable Cause

The affidavit failed to establish probable cause because [IDENTIFY THE MISSING FACTS OR UNSUPPORTED INFERENCES]. In particular, [EXPLAIN THE RELIABILITY, TIMING, AND NEXUS PROBLEM USING THE RECORD].

6.2 Invalid Warrant / Warrant Exception Misapplied

6.2.1 Facial Deficiencies: The Warrant did not identify the place or person to be searched with particularity as required by the Fourth Amendment, article I, section 17 of the Idaho Constitution, and Idaho Criminal Rule 41(d)(1).

6.2.2 Timing: The information supporting probable cause was [___] days old at issuance. In light of [TYPE OF ACTIVITY, ITEMS SOUGHT, AND OTHER FACTS], it did not support a fair probability that evidence would be found at the identified place when the warrant issued.

6.2.3 Absence of an Exception: The State’s reliance on the [AUTOMOBILE / PLAIN-VIEW / CONSENT] exception is misplaced because [REASON].

6.3 Tainted Derivative Evidence

Defendant seeks suppression of [IDENTIFY EACH DERIVATIVE STATEMENT, OBSERVATION, OR ITEM] because [EXPLAIN ITS CAUSAL CONNECTION TO THE ASSERTED VIOLATION]. The Court should address any asserted inevitable-discovery or other applicable limit for each item. State v. Campbell, No. 49269 (Idaho Mar. 26, 2026), at 15–20 (substitute opinion). Campbell did not decide whether the federal attenuation standard applies under the Idaho Constitution; brief that question separately if raised. Discovery after the challenged search alone does not establish exclusion.

6.4 No Good-Faith Exception Applies (State v. Guzman)

For the state constitutional claim, an officer's asserted good-faith reliance on the Warrant does not itself answer the exclusion question. Guzman, 122 Idaho 981, 842 P.2d 660. The separate facts bearing on any asserted limit to exclusion are [IDENTIFY EVIDENCE AND RESPOND TO STATE'S THEORY].


7. REQUEST FOR EVIDENTIARY HEARING

Pursuant to Idaho Criminal Rule 12, Defendant requests an evidentiary hearing to resolve disputed material facts, including but not limited to the accuracy of the affidavit, the circumstances of the search, and the scope of alleged consent.


8. REMEDIES SOUGHT

  1. An Order suppressing the Subject Evidence;
  2. An Order suppressing each identified derivative item or statement for which the Court makes item-specific causation and remedy findings;
  3. A determination of any further case disposition on a separately presented basis; and
  4. Any further relief the Court deems equitable.

9. SIGNATURE

Counsel for Defendant submits this Motion based on the record and supporting materials identified above. Factual disputes requiring testimony or exhibits are identified in Section 7.

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.
