United States v. Birkedahl, 973 F.3d 49

Eric Birkedahl pleaded guilty to possession of child pornography and was sentenced to 24 months' imprisonment followed by five years of supervised release. He appealed three supervised-release conditions.
The district court imposed: (1) a sex-offense treatment condition (probation will "supervise the details" including selection of provider and schedule); (2) a verification-testing condition permitting polygraph, CVSA, or other court-approved tests; and (3) a standard risk-notification condition allowing probation to require notification if the court determines the defendant poses a risk.
At sentencing Birkedahl objected: the treatment condition is unconstitutionally vague/delegates too much authority; the CVSA is scientifically unreliable and a hearing (Daubert-style) was required before allowing its use; and the risk-notification condition gives probation excessive discretion.
The district court overruled the objections, retained the CVSA reference in the verification condition (allowing probation to use CVSA and polygraph without prior court approval), and imposed the sentence.
On appeal the Second Circuit affirmed the treatment condition, dismissed as unripe Birkedahl’s challenge to the CVSA and the risk-notification condition, and otherwise affirmed the district court’s judgment.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Vagueness/delegation of sex-offense treatment condition	Condition is vague and impermissibly delegates core liberty decisions to probation	Condition only delegates administrative details (provider, schedule) which courts may leave to probation	Affirmed—delegation limited to administrative details and permissible under precedent
Inclusion of CVSA in verification-testing condition	CVSA is scientifically unreliable; court abused discretion by including it without a reliability hearing	Court may include CVSA as a verification tool and need not hold a pre-supervision scientific hearing	Dismissed as unripe—reliability is technology-dependent and may change before supervision; challenge may be raised during supervision
Standard risk-notification condition	Condition delegates too much discretion to probation to require third-party notification	Notification is contingent on a future court determination that defendant poses a risk	Dismissed as unripe—contingent event may never occur; challenge not ripe for appeal
