## Facts

- James Gregory Logan was serving supervised probation after a conviction for possession with intent to distribute cocaine; a portion of his sentence was suspended on conditions.
- While on probation, a police officer mistakenly believed Logan was another person with an outstanding felony warrant and entered Logan’s rooming house without a warrant.
- After entering, the officer went upstairs and observed a hand-to-hand crack cocaine transaction in a stairway or hallway area and arrested Logan.
- Logan was prosecuted for cocaine possession based on those observations; the conviction was later reversed because the warrantless entry violated the Fourth Amendment and the evidence was inadmissible.
- Separately, the Commonwealth sought to revoke Logan’s previously suspended sentence based on the same alleged drug conduct.
- After the drug conviction was reversed, Logan moved to dismiss the revocation proceeding, arguing it rested on a vacated conviction.
- The circuit court denied dismissal, admitted the officer’s testimony about what he observed during the unlawful entry, found a probation violation, and revoked part of the suspended sentence.

## Issues

1. Whether the Fourth Amendment exclusionary rule bars the Commonwealth from using evidence obtained through an unlawful warrantless entry—suppressed in a related criminal case—to prove a probation violation in a revocation proceeding based on the same conduct.

## Decision

- The Supreme Court of Virginia reversed the Court of Appeals and the circuit court’s revocation order.
- The court held the exclusionary rule applied on these facts and barred use of the officer’s testimony derived from the unconstitutional entry to revoke Logan’s probation.
- The case was remanded for further proceedings consistent with the ruling.

## Legal Principles

- The exclusionary rule is a judicial remedy intended primarily to deter Fourth Amendment violations and protect the integrity of judicial proceedings; application depends on balancing deterrent benefits against social costs.
- Although probation-revocation proceedings are not criminal prosecutions and may use more flexible evidentiary standards, they can result in loss of liberty based on alleged criminal conduct and therefore may implicate exclusionary-rule concerns.
- When the Commonwealth seeks to revoke probation using the same evidence already determined to be obtained in violation of the Fourth Amendment and suppressed in a related prosecution, exclusion may be required to prevent an end run around suppression and to preserve deterrence.
- The decision was tied to the specific circumstances: the revocation rested on evidence directly obtained from a clear constitutional violation and central to the alleged violation.

## Conclusion

Virginia’s high court held that the Commonwealth could not rely in a probation-revocation hearing on evidence obtained through a Fourth Amendment violation where that same evidence had been suppressed and had led to reversal of a related criminal conviction, and it reversed the revocation and remanded.
