Kernrechtsfrage
Whether the IV office was entitled to deny benefits because the insured person failed to comply with the medical instruction to undergo therapy and maintain drug abstinence.
Extrahierter Entscheid
Yes. The medical instruction and the warning procedure were considered lawful and reasonable; the positive cocaine test showed non-compliance.
Extrahierte Begründung
The court relied on the treating psychiatrist's recommendation, the intake warnings, and the formal notice of 10 May 2017. Under Art. 21 ATSG and Art. 7b IVG, refusal of reasonable cooperation may lead to denial of benefits without further substantive assessment.
