State v. Campbell

Campbell · Supreme Court of the State of Idaho · March 26, 2026 · No. 49269

Summary

The Idaho Supreme Court’s substitute opinion addresses whether police unlawfully converted an investigative detention into a de facto arrest by handcuffing Benny Dean Campbell during an investigation of a stolen motorcycle. The court affirms the district court’s conclusion that the handcuffing was unjustified, but holds that the attenuation doctrine did not apply because of the close temporal connection and lack of a meaningful intervening circumstance. The court nevertheless affirms the denial of Campbell’s suppression motion on the basis of the inevitable discovery doctrine.

Holdings

  1. The State failed to establish that handcuffing Campbell was a reasonable precaution for officer safety. Under the circumstances, ordering Campbell to lie down and placing him in handcuffs converted the investigative detention into an unlawful de facto arrest.
  2. The attenuation doctrine did not make the evidence admissible because only ten to fifteen minutes elapsed between the unlawful de facto arrest and the search, and the discovery of Campbell's probation status occurred while he remained unlawfully detained and did not meaningfully interrupt the causal chain.
  3. The inevitable-discovery issue was preserved because the district court expressly ruled that the doctrine did not apply, and that ruling became adverse to the State once the attenuation rationale was rejected.
  4. A lawful separate or independent investigation already underway is not a per se requirement for application of the inevitable-discovery doctrine. The State may instead establish inevitability through other compelling historical facts independent of the constitutional violation.
  5. Suppression was not required because the State established that the evidence would inevitably have been discovered through lawful investigative steps independent of the unlawful handcuffing.

Questions Presented

  1. Whether the trooper's use of handcuffs converted Campbell's investigative detention into an unlawful de facto arrest.
  2. Whether the attenuation doctrine purged the taint of the unlawful de facto arrest.
  3. Whether the inevitable-discovery issue was preserved for appellate review despite the State's failure to raise it below.
  4. Whether inevitable discovery requires a separate, independent investigation already underway.
  5. Whether the evidence in Campbell's backpack would inevitably have been discovered by lawful means independent of the unlawful handcuffing.
