Finney v. State — Rule 12 Waiver: Unraised Suppression Grounds (and Record-Precluding Defaults) Bar Appellate Fourth Amendment Review

1. Introduction

In Finney v. State (Del. Jan. 28, 2026), Artezz Finney appealed his conviction for possession of a firearm by a person prohibited after the Superior Court denied (in relevant part) his pretrial motion to suppress. The incident arose when Wilmington police officers, while on patrol, observed Finney alone in a parked Chevrolet Malibu holding a silver firearm. Officers approached with weapons drawn; an officer opened the door, asked where the gun was, and Finney indicated it was in the back of the vehicle. Police later conducted an inventory search at the police station and recovered a silver SIG .45 caliber firearm.

The key appellate issue was not whether the firearm should have been suppressed on the merits under the Fourth Amendment. Instead, the Delaware Supreme Court addressed a threshold procedural question: whether Finney preserved for appeal Fourth Amendment suppression theories that he did not raise in his pretrial motion—a motion that was limited to an alleged Fifth Amendment/Miranda violation.

2. Summary of the Opinion

The Court affirmed the judgment. It held that Finney waived appellate review of his newly raised Fourth Amendment claims—(i) lack of reasonable and articulable suspicion for the stop and (ii) an allegedly noncompliant inventory search—because he did not present those grounds in his pretrial motion to suppress. Relying on Swanson v. State and Superior Court Criminal Rule 12, the Court emphasized that suppression issues must be raised pretrial so the State has a fair opportunity to develop an evidentiary record. The Court also declined to reach the claims via plain-error review because the failure to raise them below left an underdeveloped record that would unfairly force the State to litigate on a record shaped by the defendant’s default.

3. Analysis

3.1. Precedents Cited

  • Miranda v. Arizona, 384 U.S. 436 (1966)
    Role in the case: Miranda framed the only suppression theory actually litigated in the Superior Court. Finney argued that the officer’s question (“Where is the gun?”) was custodial interrogation without Miranda warnings, requiring suppression of his response and the gun. The Superior Court partially suppressed one later statement but admitted the initial “location” response and the firearm. On appeal, however, Finney abandoned Miranda and pivoted to new Fourth Amendment theories—making Miranda principally relevant as context for why the record was developed only around a Fifth Amendment issue.
  • Gregory v. State, 616 A.2d 1198, 12 00-01 (Del. 1992)
    Role in the case: Finney cited Gregory for the proposition that the “motion to suppress, standing alone, preserved the issue[s] on appeal.” The Court rejected that reliance, explaining that Gregory addressed a different preservation problem: whether a defendant who litigated suppression pretrial must also object again at trial when the evidence is admitted. Gregory did not support Finney’s attempt to raise entirely new suppression grounds on appeal that were never presented to the trial court.
  • Swanson v. State, __ A.3d ___, 2025 WL 3778943 (Del. Dec. 31, 2025)
    Role in the case: Swanson supplied the controlling preservation principle. There, the Court “hewed to Superior Court Criminal Rule 12” and held that failing to file a pretrial motion to suppress generally waives appellate review of suppression issues. Finney differed factually because he filed a motion—but the Court treated that distinction as immaterial where the motion did not include the Fourth Amendment theories later pursued on appeal. The Court extended Swanson’s logic: a narrowly framed suppression motion does not preserve unrelated suppression grounds.
  • Suber v. State, __ A.3d. __, 2026 WL 184867, at *4 (Del. Jan. 15, 2026)
    Role in the case: Suber reinforced the Court’s refusal to use plain-error review to rescue an unpreserved suppression argument when the failure to object “effectively precluded the State from establishing an evidentiary record.” Finney’s default similarly prevented record development on the Fourth Amendment issues (reasonable suspicion; inventory-search procedures). Suber thus supported the Court’s conclusion that plain-error review was inappropriate.

3.2. Legal Reasoning

The Court’s reasoning is best understood as a procedural holding with substantive fairness underpinnings:

  1. Rule-based preservation requirement (Superior Court Criminal Rule 12): Suppression issues must be raised before trial through a motion to suppress. This is not a technicality; it is the mechanism by which the trial court adjudicates admissibility and by which the parties build the record.
  2. Issue-specific preservation: Finney’s pretrial motion challenged evidence only on a Fifth Amendment/Miranda theory. The Court treated suppression “issues” as the grounds asserted (e.g., Miranda vs. reasonable suspicion vs. inventory-search compliance), not the general subject matter (“suppress the gun”). Because the Fourth Amendment theories were not presented, they were not preserved.
  3. Record development and adversarial fairness: The Court stressed that Finney’s litigation choice deprived the State of any meaningful reason to introduce evidence addressing Fourth Amendment compliance at the suppression hearing. As a result, the appellate record was “underdeveloped” on the newly raised claims. The Court viewed it as “manifest”ly unfair to require the State to defend police conduct on a record whose gaps were caused by the defendant’s failure to raise the issue at the proper time.
  4. Plain error as a limited safety valve—not a substitute for Rule 12: Even though Finney alternatively requested plain-error review, the Court—consistent with Swanson and Suber— declined. Where the lack of an objection prevents the State from making a record, appellate review becomes structurally distorted: an appellate court would be forced either to speculate about missing facts or to penalize the State for not proving matters it had no incentive (or opportunity) to prove.

3.3. Impact

The decision’s practical effect is to sharpen Delaware’s preservation doctrine for suppression litigation:

  • Defense counsel must raise all intended suppression theories pretrial: Filing a suppression motion on one ground (e.g., Miranda) will not preserve distinct grounds (e.g., reasonable suspicion, warrant exceptions, inventory policy compliance) for appeal.
  • Appellate courts will resist plain-error review where the defendant’s default caused the evidentiary gap: Finney signals that “plain error” is unlikely to revive a suppression claim when the missing record is the predictable consequence of not raising the issue in the Superior Court.
  • Prosecutorial incentives and trial-court administration: The State is not expected to preemptively litigate every conceivable suppression theory at a hearing focused on a different constitutional claim. This promotes efficient hearings and aligns evidentiary presentation with the issues actually joined by the pleadings.

4. Complex Concepts Simplified

  • Motion to suppress: A pretrial request asking the court to exclude evidence because it was obtained in violation of the Constitution or other legal rules.
  • Custodial interrogation / Miranda: If a person is in custody and police interrogate them, police generally must provide Miranda warnings before questioning; otherwise, certain statements may be excluded.
  • Reasonable and articulable suspicion: The minimum justification police typically need to stop a person or vehicle briefly to investigate possible criminal activity.
  • Inventory search: A search of a vehicle (often after impoundment) aimed at cataloging property for safekeeping and protecting police from claims of theft—generally lawful only if conducted under standardized procedures rather than as a pretext to search for evidence.
  • Waiver (in this context): Losing the right to appellate review of an argument because it was not timely raised in the trial court.
  • Plain error: A narrow appellate doctrine permitting review of certain unpreserved errors, typically reserved for clear mistakes affecting substantial rights; Finney underscores that it is not applied when the lack of objection prevented fair record development.

5. Conclusion

Finney v. State reinforces and effectively extends the procedural rule articulated in Swanson v. State: suppression arguments are issue-specific and must be raised in a pretrial motion under Superior Court Criminal Rule 12, or they are generally waived on appeal. The Court also makes clear—consistent with Suber v. State—that it will not use plain-error review to adjudicate newly minted Fourth Amendment theories when the defendant’s failure to raise them below left the record inadequately developed. In broader context, Finney is a strong statement that appellate review of suppression disputes depends on disciplined issue framing and record building at the trial level.
