64 F. Supp. 3d 659
E.D. Pa.2014Background
- William S. Dahl, a convicted sex offender on Delaware probation with written search and electronic-use conditions, was supervised by Probation Officer Edward Rutkowski.
- Delaware probation conditions authorized warrantless searches of person, living quarters, vehicle upon reasonable suspicion and prohibited internet sexual activity; Dahl was subject to electronic monitoring and prohibited contact with persons under 21.
- Pennsylvania undercover officer (posing as a 15-year-old) communicated with Dahl via Craigslist/email/text; Dahl allegedly sent photos (face and penis) and attempted to arrange a sexual meeting in Delaware.
- On Nov. 21, 2013, after receiving corroborating information, Rutkowski and law enforcement detained Dahl as he returned to his car; officers recovered three cell phones from the vehicle; one smartphone rang when called by the undercover officer.
- Rutkowski inspected the phones at the probation office and found the photographs and texts matching the undercover’s evidence; a later forensic search by Delaware State Police produced a disk of phone contents.
- Dahl moved to suppress phone evidence as a warrantless search in violation of the Fourth Amendment; the court held an evidentiary hearing and denied the motion.
Issues
| Issue | Plaintiff's Argument (Dahl) | Defendant's Argument (Gov.) | Held |
|---|---|---|---|
| Validity of warrantless search of cell phone seized from vehicle | Warrant required under Riley; search violated Fourth Amendment | Search justified by probation search condition and reasonable suspicion | Denied suppression: search lawful under probation-search standard |
| Effect of probationer status on Fourth Amendment protection | Probationer still entitled to Riley protections for cell phones | Probationers have diminished privacy; state-condition permits warrantless searches with reasonable suspicion | Probation exception (Knights) applies; reasonable suspicion sufficed |
| Whether Riley v. California supersedes Knights for probationer cell-phone searches | Riley requires warrant for cell-phone searches incident to arrest and undermines Knights | Knights remains viable; Riley preserves case-specific exceptions (exigent/custodial limits) and does not eliminate probationer rule | Riley does not displace Knights in this context; Knights survives |
| Good-faith reliance on pre-Riley precedent | Search was unlawful regardless of officer belief | Officer acted objectively reasonably under then-existing law (alternative argument) | Court did not need to reach good-faith analysis because search upheld under Knights (reasonable suspicion) |
