Case Explained: USA V. TIEDEMANN

Court: United States Court of Appeals for the Ninth Circuit

Filed: 2026-07-16

Docket: 3:14-cr-02316-MMA-1

The Ninth Circuit affirmed the district court’s revocation of Kenneth Daniel Tiedemann’s supervised release and its imposition of special conditions of supervision. Regarding the revocation, the court applied de novo review to the application of the exclusionary rule and Fifth Amendment self-incrimination claims, holding that neither applies to supervised release proceedings. The court ruled that the exclusionary rule is inapplicable to such hearings and that the Fifth Amendment right against self-incrimination extends only to criminal cases, not revocation proceedings; thus, Tiedemann’s failure to provide his smartphone password did not violate his constitutional rights. Regarding the special conditions, the court applied an abuse of discretion standard for the imposition of conditions and a de novo standard for constitutional challenges. The court found that restricting internet use was reasonably related to the offense since internet use was essential to the crime. It held that authorizing polygraph examinations as part of a treatment program did not impermissibly delegate judicial authority, as such testing is incidental to treatment goals. Conditions restricting encryption, cloud storage, and software updates were deemed reasonable given the defendant’s prior use of encryption to hinder forensic review and the discovery of child erotica on cloud sites. The court also upheld a restriction on access to explicit adult content involving adults under 18 U.S.C. § 2257(h)(1), finding it reasonably related to the possession of child pornography and not overly broad. Finally, regarding a condition allowing monitoring of all computer and cellular data, the court accepted the Government’s proposal to construe the condition to monitor only internet-related activities, thereby avoiding overbreadth concerns without requiring remand. The judgment is affirmed.
