1. Introduction

1.1 Defendant seeks suppression of:
a. Physical evidence seized from [LOCATION] on [DATE];
b. Any and all observations made by law-enforcement officers during said search; and
c. All statements obtained from Defendant subsequent to, and as a direct result of, the unlawful governmental conduct.

1.2 The challenged evidence was obtained in violation of the Fourth Amendment to the United States Constitution and Article VI, § 11 of the South Dakota Constitution. Absent suppression, Defendant's fundamental rights will be irreparably prejudiced.


2. Procedural Posture

2.1 This Court, a circuit court of the State of South Dakota, has original criminal jurisdiction over this felony/misdemeanor prosecution under SDCL § 16-6-12.

2.2 Defendant was charged by [COMPLAINT/INFORMATION/INDICTMENT] filed on [DATE] with [LIST COUNT(S)].

2.3 Discovery produced by the State on [DATE] revealed that the evidence at issue was obtained through the search described in Section 3, infra. A motion to suppress evidence must be raised before trial under SDCL § 23A-8-3(4) (Rule 12(b)), and this Motion is timely filed within the time set by the Court under SDCL § 23A-8-4 (Rule 12(c)) and any applicable local rules. Failure to timely raise this issue may result in waiver under SDCL § 23A-8-9 (Rule 12(f)).


3. Factual Background

3.1 On [DATE/TIME], Officers [NAMES] entered [LOCATION] without a warrant.

3.2 Defendant was [detained/arrested] and questioned on-scene, after which officers seized [ITEMS].

3.3 The alleged basis for entry was [E.G., anonymous tip, protective sweep, consent, search warrant issued by Magistrate [NAME]]. The facts demonstrate no lawful justification, as detailed below.


4. Argument

4.1 Governing Legal Standard

4.1.1 A defendant aggrieved by an unlawful search or seizure may move to suppress the resulting evidence before trial. SDCL § 23A-8-3(4) (Rule 12(b)). The circuit court must determine the motion before trial unless, for good cause, it orders that the motion be deferred for determination at trial. SDCL § 23A-8-8 (Rule 12(e)).

4.1.2 The South Dakota Constitution "furnishes a supplemental source of individual rights that may afford greater protection than the federal constitution." State v. Opperman, 247 N.W.2d 673, 674 (S.D. 1976). Once a defendant establishes a prima facie constitutional violation, the State bears the burden of proving the legality of the search and seizure.

4.2 The Warrantless Search Was Unreasonable

4.2.1 Warrantless searches are per se unreasonable absent a narrow, well-delineated exception. None apply here:
a. No valid consent – Defendant unequivocally withheld consent;
b. No exigency – Officers had time to secure a warrant but failed to do so;
c. No plain-view doctrine – Officers were unlawfully present when observations were made.

4.2.2 Accordingly, all items seized must be suppressed as primary evidence obtained in violation of the Fourth Amendment and Article VI, § 11 of the South Dakota Constitution.

4.3 Alternatively, the Warrant Was Constitutionally Defective

4.3.1 The supporting affidavit lacked probable cause because it relied on:
a. Stale information;
b. Unsupported anonymous tips; and
c. Boilerplate language devoid of particularized facts.

4.3.2 A neutral magistrate could not have found probable cause under these circumstances, rendering the warrant facially invalid under the totality-of-the-circumstances test applied in South Dakota. See State v. O'Connor, 378 N.W.2d 248 (S.D. 1985) (adopting the Illinois v. Gates totality-of-the-circumstances standard for probable-cause determinations under S.D. Const. art. VI, § 11).

4.4 Scope of the Search Exceeded Any Lawful Authorization

4.4.1 Even assuming arguendo that a warrant or exception existed, officers searched areas (e.g., closed containers, adjoining structures) that were outside any permissible scope. Evidence seized from impermissible areas must therefore be suppressed.

4.5 Statements and Derivative Evidence Must Also Be Suppressed

4.5.1 Defendant's statements were obtained following the unlawful search and constitute fruit of the poisonous tree.

4.5.2 Additionally, officers failed to honor Defendant's rights under Miranda v. Arizona, 384 U.S. 436 (1966), by [failing to administer warnings / continuing interrogation after invocation of the right to counsel or to remain silent], providing an independent basis for suppression of the resulting statements and any evidence derived therefrom.

4.6 The Good-Faith Exception Does Not Apply

4.6.1 South Dakota recognizes a good-faith exception to the exclusionary rule under both the Fourth Amendment and Article VI, § 11 of the South Dakota Constitution. State v. Saiz, 427 N.W.2d 825, 828 (S.D. 1988) (adopting the reasoning of United States v. Leon, 468 U.S. 897 (1984), under the South Dakota Constitution "as far as that case has been applied and limited").

4.6.2 Under Saiz and Leon, the exception does not apply, and suppression remains the appropriate remedy, where:
a. The issuing magistrate was misled by information in an affidavit that the affiant knew was false, or would have known was false but for reckless disregard of the truth;
b. The issuing magistrate wholly abandoned a neutral and detached judicial role;
c. The affidavit was so lacking in indicia of probable cause that official belief in its existence was entirely unreasonable; or
d. The warrant was so facially deficient — in failing to particularize the place to be searched or the things to be seized — that the executing officers could not reasonably presume it to be valid.

4.6.3 Any purported reliance here falls within one or more of the above exclusions and was objectively unreasonable; thus, the exclusionary rule's deterrent purpose will be served only by suppression.


5. Request for Evidentiary Hearing

5.1 Defendant requests a full evidentiary hearing to resolve factual disputes surrounding the search, seizure, and interrogation, consistent with the Court's authority to set and hear pretrial motions under SDCL § 23A-8-4 (Rule 12(c)) and to make findings of fact under SDCL § 23A-8-8 (Rule 12(e)). Should newly discovered evidence bearing on suppression arise, Defendant reserves the right to request a subsequent hearing under SDCL § 23A-8-5.


6. Conclusion & Prayer for Relief

WHEREFORE, Defendant respectfully requests that this Court:

  1. Conduct an evidentiary hearing on the issues raised herein;
  2. Suppress all physical evidence, observations, and statements obtained as a result of the unconstitutional search, seizure, and interrogation;
  3. Exclude from trial any derivative evidence or testimony; and
  4. Grant such further relief as the Court deems just and proper.

7. Notice of Motion

PLEASE TAKE NOTICE that the undersigned will bring the foregoing Motion on for hearing before the Honorable [JUDGE NAME], at the [COURTHOUSE], [COURTROOM NUMBER], [ADDRESS], on [DATE] at [TIME], or as soon thereafter as counsel may be heard.

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.
