Rule 40(e)(1) Nighttime-Execution Violations Do Not Trigger Automatic Suppression Absent a Constitutional Violation, Bad Faith, or Prejudice

Introduction

In State v. Jaramillo, 2026 UT 20, the Utah Supreme Court addressed whether evidence must be suppressed when police execute a search warrant at night even though the warrant, as issued, authorizes only daytime execution under rule 40(e)(1) of the Utah Rules of Criminal Procedure.

The case arose from a traffic stop of Anthony Ernesto Jaramillo that led to the discovery of a gun and drugs, followed by two warrants: (1) a warrant to search Jaramillo’s home for evidence of drug dealing and (2) a warrant to obtain a blood draw to test for drugs and DNA swabs to connect Jaramillo to the gun. In both warrant applications, the officer intended to request nighttime authorization through the UCJIS system but inadvertently failed to do so, resulting in warrants that authorized execution only “in the daytime.” Police nevertheless executed both warrants at night.

The district court suppressed the evidence solely because rule 40(e)(1) was violated, despite finding no bad faith and despite acknowledging the magistrate likely would have authorized nighttime service if requested. On interlocutory review (certified from the court of appeals), the Utah Supreme Court reversed, holding that suppression cannot rest on the rule violation alone.

Summary of the Opinion

The Utah Supreme Court reaffirmed the remedial framework from State v. Fixel and State v. Rowe: suppression for a violation of Utah criminal procedure rules is warranted only when the violation (1) also implicates constitutional rights, (2) is committed in bad faith, or (3) substantially prejudices the defendant (i.e., the search might not have happened or would have been less abrasive had the rule been followed).

Because the district court (a) found no bad faith, (b) rejected prejudice, and (c) did not decide whether the nighttime execution violated the Fourth Amendment (or Utah’s Constitution), its suppression order rested on the rule violation alone, contrary to Fixel and Rowe. The Supreme Court reversed and remanded, expressly declining—given the interlocutory posture—to affirm on alternative constitutional grounds.

Analysis

Precedents Cited

  • State v. Fixel, 744 P.2d 1366 (Utah 1987)
    • Role in Jaramillo: Provides the foundational Utah rule that suppression is a disproportionate remedy for many nonconstitutional procedural violations and is reserved for (1) constitutional violations, (2) bad faith, or (3) substantial prejudice.
    • Key move: Fixel adopted (as persuasive) a framework articulated by the Pennsylvania Supreme Court to distinguish “fundamental” violations (constitutional in effect) from nonfundamental procedural errors.
  • Commonwealth v. Mason, 490 A.2d 421 (Pa. 1985)
    • Role in Jaramillo (via Fixel): Supplies the conceptual definitions the Utah Supreme Court uses: a “fundamental” violation is one that effectively renders the search unconstitutional; otherwise suppression requires prejudice or intentional disregard.
  • State v. Rowe, 850 P.2d 427 (Utah 1992)
    • Role in Jaramillo: Directly governs rule 40(e)(1)-type errors (nighttime authorization defects). Rowe held that an unjustified nighttime-search authorization defect did not automatically require suppression absent constitutional concerns, bad faith, or prejudice.
    • Doctrinal contribution: Rowe operationalizes Fixel for nighttime-search requirements and is treated as controlling precedent.
  • State v. Tran, 2024 UT 7, 545 P.3d 248
    • Role in Jaramillo: Cited for the standard of review on suppression rulings: correctness, including application of law to facts.
  • State v. Price, 2012 UT 7, 270 P.3d 527
    • Role in Jaramillo: Cited for how facts are recited on interlocutory review (consistent with the trial court’s findings).
  • United States v. Green, 178 F.3d 1099 (10th Cir. 1999)
    • Role in Jaramillo: Cited by the district court for the proposition that warrant execution is subject to Fourth Amendment reasonableness. The Utah Supreme Court did not rely on Green to decide the constitutional question; it focused on the remedy under Utah procedural law.
  • State v. Valle-Flores, 2005 UT App 290, 117 P.3d 1069
    • Role in Jaramillo: Used by the district court for the idea that technical/ministerial mistakes typically do not justify the “extreme sanction” of suppression. The Utah Supreme Court’s reversal effectively re-centers the analysis on the Rowe/Fixel three-part test.
  • O'Rourke v. City of Norman, 875 F.2d 1465 (10th Cir. 1989)
    • Role in Jaramillo: Cited by the district court as a federal case treating nighttime execution of a daytime-only warrant as unconstitutional. The Utah Supreme Court noted the citation but held the district court never actually decided the constitutional issue here.

Legal Reasoning

  1. Rule 40(e)(1) was violated as a matter of undisputed fact.

    Rule 40(e)(1) makes daytime execution the default and allows nighttime execution only if the affidavit/testimony provides sufficient grounds and the magistrate authorizes it. The officer’s UCJIS applications sought “daytime” execution only; both warrants were executed at night.

  2. The remedy is governed by the Fixel/Rowe suppression framework, not by the rule text alone.

    The court treated State v. Fixel and State v. Rowe as binding: a procedural rule violation does not itself mandate suppression. Suppression is reserved for three categories: constitutional violation, bad faith, or substantial prejudice.

  3. The district court’s findings eliminated two suppression pathways and left the third undecided.
    • No bad faith: The district court expressly found no malicious intent and no attempt to “get around” the daytime requirement.
    • No prejudice (as the district court analyzed it): It acknowledged the magistrate likely would have granted nighttime authorization and that execution was peaceful, but it suppressed anyway to enforce the magistrate-scrutiny step.
    • No constitutional ruling: Although the district court referenced Fourth Amendment reasonableness and cited cases like O'Rourke v. City of Norman, it did not hold that these searches violated the Fourth Amendment (or Utah’s Constitution).
  4. Because suppression rested on the “rule violation alone,” it conflicted with Rowe and required reversal.

    The Supreme Court read the suppression order as essentially creating an automatic exclusionary rule for rule 40(e)(1) violations. That approach “contradicts” Fixel and Rowe.

  5. Interlocutory posture limited the court’s willingness to reach alternative constitutional grounds.

    Jaramillo urged affirmance on Fourth Amendment and Utah constitutional grounds. The court declined, emphasizing that the district court had not decided those issues and that, on interlocutory review, it would not resolve them as alternative bases to affirm.

Impact

  • No “automatic suppression” for nighttime execution errors under rule 40(e)(1): Trial courts must apply Rowe and Fixel and may not suppress solely to enforce procedural compliance.
  • Sharper separation between (a) rule compliance and (b) exclusionary remedy: The opinion reinforces that Utah’s procedural rules can be stricter than constitutional minima, but stricter procedural protection does not automatically carry the remedy of exclusion absent the three Rowe/Fixel conditions.
  • Litigation shifts to constitutional and prejudice analysis: Defendants challenging unauthorized nighttime execution will likely focus on proving either (1) a Fourth Amendment/Utah constitutional violation, (2) deliberate disregard, or (3) meaningful prejudice (e.g., the magistrate might have refused nighttime authorization, or execution was more intrusive).
  • Operational consequence for warrant practice (UCJIS checkbox errors): The case highlights how administrative UI failures can create legal risk; however, absent bad faith or prejudice (or a constitutional violation), the remedy will not necessarily be suppression.

Complex Concepts Simplified

Suppression (the exclusionary rule)
A remedy that prevents the government from using certain evidence at trial. In Utah procedural-rule cases, suppression is not automatic; it depends on the Fixel/Rowe test.
Rule 40(e)(1) (daytime vs. nighttime execution)
Utah’s rule presumes warrants are served in the daytime. To serve at night, police must present reasons in the affidavit/testimony and obtain the magistrate’s authorization.
Bad faith
More than negligence—an intentional and deliberate disregard of the rule. The district court found the officer’s failure was inadvertent, not bad faith.
Prejudice (in this context)
Under Fixel/Rowe, prejudice means the search might not have occurred, or would have been less intrusive (“less abrasive”), if the rule had been followed.
Fundamental (constitutional) violation
A procedural violation becomes “fundamental” if it effectively amounts to a constitutional violation under Fourth Amendment standards. The Supreme Court held the district court did not decide this question.
Interlocutory review
An appeal that occurs before the case is fully resolved in the trial court. Here, the Supreme Court reviewed the suppression order mid-case and declined to decide constitutional issues the district court had not reached.

Conclusion

State v. Jaramillo reaffirms a clear remedial rule in Utah: a violation of rule 40(e)(1)—including executing a daytime-only warrant at night— does not justify suppression by itself. Under State v. Fixel and State v. Rowe, exclusion is reserved for cases involving a constitutional violation, bad-faith disregard of the rule, or substantial prejudice.

The decision’s broader significance is institutional as much as doctrinal: it preserves magistrate-centered warrant procedures as important safeguards, but it limits the exclusionary remedy to the circumstances Utah precedent has defined—thereby preventing suppression from becoming an automatic sanction for procedural noncompliance.
