413 P.3d 419
Idaho Ct. App.2017Background
- Fenton was on felony probation and had signed a probation agreement requiring him to identify himself to police and to consent to searches by probation or law enforcement.
- An officer observed Fenton driving from a location associated with drug activity and ran the vehicle plate; dispatch misinterpreted the plate leading to multiple plate checks and a traffic stop without reasonable suspicion.
- During the stop the officer issued citations for no license and no proof of insurance; Fenton volunteered he was on probation and gave his probation officer’s name.
- The officer notified the probation officer, who arrived, had Fenton sit on the sidewalk, and requested the officer’s assistance searching the vehicle; methamphetamine was found.
- Fenton was charged with trafficking; he moved to suppress evidence arguing the traffic stop and the subsequent probation search were unlawful. The district court granted suppression, finding the stop lacked reasonable suspicion.
- The State appealed, arguing the attenuation doctrine purged the taint of the unlawful stop and the evidence should be admissible.
Issues
| Issue | Plaintiff's Argument (State) | Defendant's Argument (Fenton) | Held |
|---|---|---|---|
| Whether attenuation doctrine permits admission of evidence obtained after an unlawful stop | The causal chain was sufficiently attenuated because Fenton voluntarily disclosed probation status, the probation officer’s independent decision to search was an intervening act, and the officer’s mistake was not flagrant | The probation search is discretionary and therefore a weaker intervening circumstance than an arrest on a warrant; suppression required because the stop was unlawful | Court reversed suppression: attenuation applied and evidence admissible |
| Temporal proximity between unlawful stop and evidence discovery | ~50 minutes elapsed; this interval (under two hours) does not prevent attenuation given other factors | Argues the relatively short interval favors suppression | Court: temporal factor favored suppression (50 minutes within two-hour window) but was weighed with other factors |
| Intervening circumstances and voluntariness of probation disclosure | Fenton’s statement of probation status (required by his agreement) and the probation officer’s independent decision to search were significant intervening acts breaking the causal chain | Contends probation condition is less compelling than an arrest warrant and probation searches are discretionary | Court: intervening circumstances weighed against suppression; disclosure voluntary and probation officer independent |
| Flagrancy/purpose of officer’s conduct (deterrence inquiry) | The officer’s errors were at worst negligent, isolated, not investigatory misconduct aimed at discovering evidence, so deterrence via exclusion unnecessary | Argues the officer’s conduct was reckless or grossly negligent and should be deterred by exclusion | Court: misconduct was not flagrant or deliberate; deterrence rationale did not support suppression |
