State v. Dorff, 526 P.3d 988

Police stopped Kirby Dorff’s car for traffic violations; Dorff lacked a valid license and proof of insurance.
A K-9 (Nero) circled the vehicle during the stop; Nero did not enter the interior but repeatedly sniffed seams, wheel wells, and undercarriage.
On the second pass Nero jumped and planted his two front paws on the driver‑side door/window and sniffed upper seams; Nero then alerted.
Officers searched the car and found methamphetamine residue and related items; further investigation led to a motel search and additional meth evidence.
Dorff moved to suppress, arguing (1) Nero’s physical contact was a common‑law trespass and thus a warrantless Fourth Amendment search, and (2) Nero’s alert was unreliable; the district court rejected both claims and denied suppression.
The Idaho Supreme Court, reviewing the body‑cam video de novo for the trespass issue, held Nero’s paw placement was intermeddling (a trespass) and therefore a warrantless search; it reversed suppression and vacated Dorff’s conviction and remanded.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether a drug dog’s physical contact with a vehicle exterior during an exterior ("free‑air") sniff is a common‑law trespass constituting a Fourth Amendment "search"	State: No Fourth Amendment violation because the sniff occurred outside the vehicle and contacts were minimal; exterior sniffs generally are not searches (Caballes).	Dorff: Nero’s paw placement constituted "intermeddling"/trespass to chattel done for the purpose of obtaining information, so it was a warrantless search under Jones.	Court held Nero’s planting of front paws on driver‑side door/window amounted to intermeddling (trespass) for the purpose of obtaining information, so a warrantless search occurred; suppression warranted.
Validity/reliability of Nero’s alert	State: Nero’s alert provided probable cause to search; dog was reliable.	Dorff: The alert was unreliable and invalid.	District court found the alert reliable; that ruling was not challenged on appeal and the Supreme Court resolved the case on trespass grounds.
