IV. APPLICABLE LEGAL STANDARDS
A. Constitutional Framework
Fourth Amendment. The Fourth Amendment to the United States Constitution prohibits unreasonable searches and seizures and requires that warrants be supported by probable cause. Mapp v. Ohio, 367 U.S. 643 (1961) (exclusionary rule applicable to states through the Fourteenth Amendment).
Kentucky Constitution, Section 10. Section 10 provides:
"The people shall be secure in their persons, houses, papers and possessions, from unreasonable search and seizure; and no warrant shall issue to search any place, or seize any person or thing, without describing them as nearly as may be, nor without probable cause supported by oath or affirmation."
Section 10 is Kentucky's search-and-seizure guarantee. The Kentucky Supreme Court looks to federal Fourth Amendment decisions for guidance when construing it. Commonwealth v. Reed, No. 2020-SC-0116-DG (Ky. June 16, 2022).
B. Kentucky Procedural Requirements
RCr 8.27 — Suppression of Evidence. RCr 8.27, adopted by Supreme Court Order 2014-22 (eff. Jan. 1, 2015) as the current successor to former RCr 9.78 (deleted by the same Order), governs motions to suppress evidence in Kentucky. RCr 8.27(2) requires that "[t]he court shall conduct a hearing on the record and before trial on issues raised by a motion to suppress evidence," and that "[n]o jury and no prospective juror shall be present at any such hearing." On appellate review, the trial court's findings of fact are conclusive if supported by substantial evidence, while its application of the law to those facts is reviewed de novo. Whitlow v. Commonwealth, 575 S.W.3d 663, 668 (Ky. 2019).
RCr 8.18 — Pre-Trial Motions. RCr 8.18(1)(f) provides that "[e]xcept for good cause shown," a motion to suppress evidence under RCr 8.27 shall be raised before trial. RCr 8.27(1) further specifies that the motion must be filed by the deadline the court sets under RCr 8.20, or, absent such a deadline, within a reasonable time before trial. This ensures timely resolution of suppression issues and preserves the Commonwealth's right to interlocutory appellate review before jeopardy attaches.
C. Burden of Proof
Warrantless searches are presumptively unreasonable. Where the Commonwealth relies on an exception to justify a warrantless search of a dwelling, it bears the burden of showing the exceptional circumstances. Vale v. Louisiana, 399 U.S. 30, 34 (1970). Defendant challenges the asserted exception here because [IDENTIFY FACTS AND EXCEPTION].
If Defendant seeks a hearing on the truthfulness of a warrant affidavit, Defendant must make a substantial preliminary showing that the affiant deliberately or recklessly included a false statement that was necessary to the finding of probable cause. Franks v. Delaware, 438 U.S. 154, 155-56 (1978).
D. Exclusionary Rule and Fruit of the Poisonous Tree
Evidence obtained in violation of the Fourth Amendment or Section 10 of the Kentucky Constitution may be subject to suppression. Mapp v. Ohio, 367 U.S. 643 (1961). Derivative evidence obtained by exploitation of the primary illegality may also be excluded unless the connection has been sufficiently purged of the taint. Wong Sun v. United States, 371 U.S. 471, 487-88 (1963).
Three narrow exceptions may save derivative evidence from suppression: (1) independent source, (2) inevitable discovery, and (3) attenuation of the taint. Nix v. Williams, 467 U.S. 431 (1984); Utah v. Strieff, 579 U.S. 232 (2016). The Commonwealth bears the burden of proving the applicability of any such exception.
E. Good-Faith Exception
Kentucky has adopted the good-faith exception articulated in United States v. Leon, 468 U.S. 897 (1984), holding that its application to the warrant requirement does not violate Section 10 of the Kentucky Constitution. Crayton v. Commonwealth, 846 S.W.2d 684, 688-89 (Ky. 1992). However, the exception does not apply where: (1) the affiant misled the magistrate with false information, knowingly, intentionally, or with reckless disregard for the truth; (2) the magistrate abandoned the judicial role or merely acted as a "rubber stamp" for the police; (3) the affidavit was so lacking in probable cause as to make reliance entirely unreasonable; or (4) the warrant was so facially deficient that officers could not reasonably rely on it. Leon, 468 U.S. at 923; Crayton, 846 S.W.2d at 688.
V. ARGUMENT
A. The Warrantless Search Was Unconstitutional
-
The search of Defendant's [________________________________] was conducted without a warrant, triggering the presumption of unconstitutionality under the Fourth Amendment and Kentucky Constitution § 10.
-
No exception to the warrant requirement applies:
☐ Consent. Any purported consent was not voluntarily, knowingly, and intelligently given. The totality of the circumstances — including [________________________________] — demonstrates that Defendant's will was overborne by law enforcement coercion. Schneckloth v. Bustamonte, 412 U.S. 218 (1973); Commonwealth v. Lucas, 195 S.W.3d 416, 420 (Ky. 2006).
☐ Exigent Circumstances. No exigency justified the warrantless entry. Officers had sufficient time to obtain a warrant and faced no imminent threat of evidence destruction, harm to persons, or hot pursuit. Kentucky v. King, 563 U.S. 452 (2011); Commonwealth v. McManus, 107 S.W.3d 175, 179 (Ky. 2003).
☐ Search Incident to Arrest. The search exceeded the permissible scope under Chimel v. California, 395 U.S. 752 (1969), and Arizona v. Gant, 556 U.S. 332 (2009), or the underlying arrest itself lacked probable cause.
☐ Automobile Exception. Officers lacked probable cause to believe the vehicle contained evidence of a crime. Carroll v. United States, 267 U.S. 132 (1925).
☐ Plain View. The incriminating nature of the items was not immediately apparent. Horton v. California, 496 U.S. 128, 136 (1990).
☐ Terry Stop/Frisk. Officers lacked reasonable articulable suspicion to justify the initial stop and/or reasonable belief that Defendant was armed and dangerous. Terry v. Ohio, 392 U.S. 1 (1968).
B. Defendant's Statements Were the Fruit of the Illegal Detention
-
Defendant challenges these statements because [EXPLAIN HOW THE CHALLENGED DETENTION OR SEARCH LED TO EACH STATEMENT]. Temporal sequence alone does not settle whether a statement was obtained by exploitation of an illegality. Wong Sun, 371 U.S. at 487-88.
-
Miranda warnings, if given, do not attenuate the constitutional violation under these facts because the causal connection between the illegality and the statements was not sufficiently broken by intervening circumstances. Brown v. Illinois, 422 U.S. 590, 603-04 (1975).
-
☐ Defendant was in custody because [FACTS], was interrogated by [OFFICER] about [SUBJECT] before receiving Miranda warnings, and made [IDENTIFY STATEMENT]. Defendant seeks exclusion of that statement from the Commonwealth's case-in-chief under Miranda v. Arizona, 384 U.S. 436, 444 (1966). A voluntary unwarned statement may still be used to impeach Defendant's testimony if its trustworthiness meets legal standards; any disputed use requires a separate ruling. Harris v. New York, 401 U.S. 222, 224-26 (1971).
C. Challenged Derivative Evidence
-
Defendant seeks suppression of the following evidence obtained by exploitation of the challenged search: [IDENTIFY EACH ITEM AND ITS CONNECTION TO THE CHALLENGED CONDUCT]. The Court should decide the admissibility of each item under Wong Sun, 371 U.S. at 487-88.
-
Defendant disputes any claimed independent source, inevitable discovery, or attenuation for these items because [STATE THE RELEVANT FACTS]. See Nix v. Williams, 467 U.S. 431, 443-44 (1984).
D. The Good-Faith Exception Is Inapplicable
- ☐ Officers did not rely on a warrant; the good-faith exception is unavailable.
- ☐ The warrant affidavit was so deficient that no objectively reasonable officer could have relied upon it.
- ☐ The affiant made knowing or reckless misrepresentations in the warrant application.
- Suppression serves the deterrent purpose of the exclusionary rule. Davis v. United States, 564 U.S. 229, 238 (2011).
VI. REQUEST FOR EVIDENTIARY HEARING
Pursuant to RCr 8.27, Defendant requests an evidentiary hearing to resolve contested issues of fact, including but not limited to:
- The officers' basis for initiating contact with Defendant;
- The existence (or lack) of voluntary consent;
- The presence or absence of probable cause or reasonable suspicion;
- The timeline of events relative to Miranda warnings;
- The scope and manner of the search;
- The chain of custody of the seized evidence; and
- The veracity of the warrant affidavit (if applicable).
Defendant anticipates calling the following witnesses:
- [________________________________]
- [________________________________]
Estimated hearing time: [____] hours.
VII. PRAYER FOR RELIEF
WHEREFORE, Defendant respectfully prays that this Court:
A. Conduct an evidentiary hearing pursuant to RCr 8.27;
B. Enter an Order suppressing:
(i) All physical evidence seized on [__/__/____];
(ii) The identified oral or written statements for which the Court finds a ground requiring exclusion, with the scope of exclusion stated for each;
(iii) The derivative evidence identified in Section V.C, if the Court finds it was obtained by exploitation of the violation and is not admissible under an applicable exception;
C. Instruct the Commonwealth to refrain from referencing the suppressed evidence in the presence of the jury;
D. Enter findings of fact and conclusions of law on the suppression issues presented; and
E. Grant such other and further relief as this Court deems just and proper.
Respectfully submitted this [____] day of [________________________________], 20[____].

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.
