Kernrechtsfrage
Whether a new psychiatric expert opinion was required before extending the probation period of conditional release from a stationary measure.
Extrahierter Entscheid
A new expert opinion was not required because the lower court could rely on the existing reports; the material circumstances had not changed in a way that made the earlier assessment outdated.
Extrahierte Begründung
The Court held that the decisive question is not the age of the report alone, but whether the factual basis has materially changed. Given the long treatment history, recent reports, and indications that the chronic disorder had not changed, the lower court did not violate federal law by refusing to order a fresh opinion.
