We allowed review in this case to consider whether the exclusionary rule applies in a probation revocation proceeding. The Court of Appeals held that it does not.
State ex rel Juv. Dept. v. Rogers,
Petitioner is a juvenile who had been placed on probation by the juvenile court for conduct that would have been crimes if committed by an adult. ORS 419.476(l)(a). The state filed a petition alleging that petitioner had violated his probation by unlawfully possessing a pistol; violating school rules; and being expelled from school because of his participation in a disturbance outside a school dance.
At his probation revocation hearing, petitioner moved to suppress the pistol as evidence, asserting that it had been seized in violation of his rights under Article I, section 9, of the Oregon Constitution.
1
The juvenile court denied the motion on the ground that, even if the pistol had been seized unlawfully, it nevertheless would be admissible, citing
State v. Kissell,
*117 Although the juvenile court’s decision to revoke petitioner’s probation was based on all three violations, the court did not state whether its decision would have been the same without the finding that he had unlawfully possessed a pistol. Nor is it apparent to us that it would have been so. The record reveals that petitioner’s possession of the pistol was the primary violation. For example, during the revocation hearing the district attorney referred to petitioner’s possession of the pistol as being the violation “of real significance in this case.” Because of the court’s ruling admitting the evidence and the likely significance of that ruling as affecting the court’s decision to revoke petitioner’s probation, the correctness of that ruling is central to the disposition of this case.
In the Court of Appeals, petitioner conceded that State v. Kissell, supra, permitted the juvenile court to admit the pistol as evidence in his probation revocation hearing regardless of the constitutionality of its seizure. He urged, however, that Kissell be overruled. The Court of Appeals declined to do so. State ex rel Juv. Dept. v. Rogers, supra.
In
State v. Nettles,
Nettles
decided the exclusionary rule issue under both Article I, section 9, of the Oregon Constitution, and the Fourth Amendment to the Constitution of the United States.
*118
For more than a decade, this court has independently construed the provisions of the Oregon Constitution without being controlled by the treatment given to a parallel provision of the federal constitution by the Supreme Court of the United States.
See State v. Kennedy,
Article I, section 9 “defines the limits of permissible conduct generally.”
State v. Davis,
Petitioner seeks to vindicate his right to be secure against unreasonable searches and seizures by prohibiting the government from using any unlawfully obtained evidence against him. As with any question concerning the breadth of the exclusionary rule, whether that rule applies in the context of a probation revocation proceeding is, fundamentally, a
*119
question of the rationale behind that rule. This court has explained that: “The answer to the question of how broad is the exclusionary rule ought to be found in the reasons for the rule.”
State Forester v. Umpqua River Nav.,
This court has stated that, “unlike the Fourth Amendment exclusionary rule, which has been based on deterring police misconduct,
[3]
exclusions under Article I, section 9, have been based on the personal right to be free from an unlawful search and seizure.”
State v. Kosta,
*120
In the past, this court has protected the individual’s constitutional right to be secure against unlawful search or seizure through the sanction of suppression of evidence in criminal prosecutions.
See State v. Davis, supra,
In this case, petitioner was at liberty, albeit with some restrictions. The term of his original probation was for two years; that term would have expired in October 1991. Since the juvenile court revoked his probation, he has been in the custody of the state. In short, he has lost his liberty. All of this may have been the result of the state’s use of unconstitutionally seized evidence. We conclude that if, in fact, the pistol was unlawfully seized in violation of petitioner’s Article I, section 9, rights, petitioner’s liberty interest is sufficiently analogous to the liberty interest at stake in traditional criminal prosecutions that the reasons for the sanction of suppression of evidence are equally applicable, requiring that the pistol be suppressed in order to vindicate petitioner’s right to be secure against an unreasonable search or seizure. We hold that the exclusionary rule applies in a probation revocation proceeding for a violation of Article I, section 9.
Cf. State v. Donovan,
The juvenile court erred in ruling that, even if the pistol was seized in violation of Article I, section 9, the pistol need not be suppressed. However, because the court made no findings about the circumstances in which the pistol was *121 seized, we cannot determine whether Article I, section 9, was violated and whether the evidence therefore should have been suppressed. Moreover, the court did not indicate whether it would have revoked petitioner’s probation based only on the two other violations unrelated to the possession of the pistol. 5 For those reasons we remand this case to the juvenile court to consider petitioner’s claim that the pistol was seized in violation of his Article I, section 9, rights and, if the court finds that the seizure violated those rights, to decide whether one or both of the other proven violations would justify revocation of his probation.
The decision of the Court of Appeals and the judgment of the circuit court are reversed. This case is remanded to the circuit court for further proceedings.
Notes
Article I, section 9, provides:
“No law shall violate the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable search, or seizure; and no warrant shall issue but upon probable cause, supported by oath, or affirmation, and particularly describing the place to be searched, and the person or thing to be seized.”
Petitioner made no argument under the United States Constitution. The parties do not argue that there is any controlling state statutory or common law, and we find none. Thus, no sub-constitutional issue is presented.
Kissell
overruled
State v. Neidenbach,
3 Under the Fourth Amendment, the primary reason for the exclusionary rule is deterrence of unlawful governmental conduct.
United States v. Leon,
In Terry v.
Ohio,
We need not decide in this case whether the sanction of suppression for violation of Article I, section 9, may be required in other contexts.
Petitioner did not challenge the juvenile court’s findings on the two other violations. During oral argument in this court, petitioner’s counsel conceded that the court could have revoked petitioner’s probation on the basis of one or both of those violations. Counsel argued, however, that but for petitioner’s unlawful possession of the pistol, the court would not have done so.
