State v. Eric Michael Ross, 378 P.3d 1056

Police stopped Ross for failing to signal. He had no license and was driving a rental; dispatch said he was not an authorized driver. A citation for driving without privileges was issued after ~25 minutes.
The rental company requested the vehicle be towed to its office. Officers told Ross the car would be towed and that they would retrieve his luggage first, but said they needed to search the luggage for weapons before returning it.
Ross refused consent to search and repeatedly stated the duffle bag in the trunk belonged to the lessee, not him. The passenger consented to a search of his own bags and received them after search.
Officers told Ross he and the passenger were free to leave; Ross began to walk away. Officers nonetheless searched and inventoried the remaining luggage; they found a handgun and methamphetamine in the duffle bag and drugs in a backpack.
Ross moved to suppress the evidence; the district court denied the motion (finding lack of standing and accepting the search as a permissible inventory). Ross pleaded guilty to firearms and trafficking charges but appealed the denial of the suppression motion.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Ross had standing to challenge search of duffle bag	Ross argues he retained a legitimate expectation of privacy because any abandonment was caused by illegal police conduct	State argues Ross voluntarily abandoned the duffle bag by disclaiming ownership and thus lacks standing	Court held Ross did have standing because abandonment was the product of illegal police activity and thus not voluntary
Whether seizure/search of luggage was lawful	Ross contends seizure and search were unlawful and not saved by inventory or consent	State contends search was a lawful inventory and that passenger consent justified returning bags	Court accepted the state's concession that the seizure was illegal and held the search/inventory was not lawful given the illegal seizure
Whether abandonment doctrine applies when police misconduct induces abandonment	Ross argues abandonment is involuntary when caused by illegal police action	State asserts abandonment was voluntary based on Ross’s statements	Court held abandonment doctrine does not apply when police misconduct causes abandonment; here abandonment was not voluntary
Remedy for illegal search/seizure	Ross seeks suppression of the evidence obtained	State effectively conceded illegality and did not oppose suppression of unlawfully seized items	Court reversed denial of suppression, vacated conviction, and remanded
