Utah Supreme Court
Can police officers contact drivers after discovering their traffic stop was based on a mistake? State v. Morris Explained
Summary
Highway patrol officer stopped Morris believing his vehicle lacked a license plate, but discovered a valid temporary registration tag upon stopping. Officer approached Morris to explain the mistake, detected alcohol odor, and conducted DUI investigation. The Court of Appeals reversed the district court’s denial of Morris’s suppression motion, holding any contact after discovering the mistake violated the Fourth Amendment.
Analysis
The Utah Supreme Court addressed an important Fourth Amendment question in State v. Morris: what happens when a police officer realizes during a traffic stop that the basis for the stop was mistaken? The Court’s ruling provides clarity for law enforcement and practitioners on the constitutional boundaries of such encounters.
Background and Facts
Highway Patrol Trooper Williams stopped Morris’s vehicle believing it lacked a visible license plate. However, upon stopping, Williams discovered a valid temporary registration tag in the rear window. Despite realizing his mistake, Williams approached Morris to explain the situation. During this contact, Williams detected alcohol odor, leading to field sobriety tests and a DUI arrest. A subsequent inventory search revealed drugs and paraphernalia.
Key Legal Issues
The case presented two critical questions: whether an officer may constitutionally contact a driver after discovering the traffic stop was based on a mistake, and whether new reasonable suspicion arising during such contact can justify continued detention. The Utah Court of Appeals had ruled that any contact after discovering the mistake violated the Fourth Amendment, creating potential confusion for motorists and officers alike.
Court’s Analysis and Holding
The Utah Supreme Court reversed, establishing a two-part framework. First, when an officer makes a traffic stop based on objectively reasonable but ultimately mistaken suspicion, the officer may approach the driver to explain the mistake. The Court emphasized that the touchstone of the Fourth Amendment is reasonableness, and leaving drivers bewildered by unexplained police departures is neither reasonable nor constitutionally required.
Second, if new reasonable suspicion immediately arises during this brief explanatory encounter, the officer may continue the detention. Here, Williams detected alcohol odor as soon as Morris rolled down his window, providing new reasonable suspicion that justified the DUI investigation. The Court stressed this holding’s limited scope—officers cannot pepper drivers with unrelated inquiries or request documents unless new suspicion immediately develops.
Practice Implications
This decision provides important guidance for both criminal defense and prosecution. Officers must have objectively reasonable grounds for the initial stop—subjective hunches or fabricated excuses remain impermissible. The explanatory contact must be brief and limited to explaining the mistake. Any continued detention requires immediate development of new reasonable suspicion based on specific articulable facts. Defense counsel should scrutinize whether the initial stop met the objective reasonableness standard and whether officers exceeded the narrow scope permitted for mistake explanations.

Case Number
No. 20090835
Date Decided
July 22, 2011

Reversed
Holding
When an officer initiates a traffic stop based on objectively reasonable but mistaken belief of a traffic violation, the officer may approach the driver to explain the mistake, and if new reasonable suspicion arises during this brief encounter, the officer may continue the detention.
Standard of Review
Correctness for conclusions of law; clear error for factual findings underlying motion to suppress
Practice Tip
Document the objective reasonableness of the initial traffic stop thoroughly, as courts will evaluate whether officers acted on specific articulable facts rather than hunches when determining if post-mistake contact is constitutionally permissible.
