State v. Jansen L. Smith
Court: Tennessee Court of Criminal Appeals Docket: M2025-00357-CCA-R3-CD Filed: April 17, 2026 County: Sequatchie County Outcome: Conviction reversed and dismissed
N. Cate Law defends Nashville DUI charges across Davidson County and Middle Tennessee. Free consultation: (615) 664-8083.
The Holding
A DUI conviction was reversed and the indictment dismissed because the officer’s detention exceeded the lawful scope of a Terry investigative stop. All evidence obtained after the stop was extended beyond its original purpose was suppressed as fruit of the poisonous tree.
Why It Matters
Traffic stops in Tennessee are constitutionally limited to the time reasonably necessary to address the original reason for the stop — usually the alleged violation that justified it. If the officer extends the encounter to develop suspicion of an unrelated offense (like DUI) without articulable, particularized suspicion that justifies the extension, the entire encounter from that point forward is unlawful, and any evidence obtained during it is suppressible.
This is one of the strongest 2026 Middle Tennessee authorities for DUI defendants whose breathalyzer results, field sobriety tests, or admissions came after an officer pivoted away from the original stop purpose. The pattern is common: a vehicle is pulled over for a tag light or lane drift, the officer notes “odor of alcohol,” and the original-violation business is set aside while the officer ramps up a DUI investigation. Smith says: if that ramp-up isn’t justified by articulable suspicion linked to the original stop, the DUI evidence falls.
If you’ve been charged with a Tennessee DUI and the basis for the stop was something minor or unrelated, the duration and scope of the stop is the first thing your defense lawyer should be analyzing.
