Kernrechtsfrage
Whether the refusal of disability benefits for breach of the duty to mitigate was lawful despite a psychiatric disorder.
Extrahierter Entscheid
The refusal was lawful because substance abuse was found to be the main cause of diminished work capacity and the insured had not undergone the required long-term abstinence treatment.
Extrahierte Begründung
The court accepted the lower court's finding that addiction, not the personality disorder, was in the foreground. A medically supervised detoxification was considered reasonable and necessary to assess residual work capacity. The insured repeatedly refused such treatment, so benefits could be denied for breach of the duty to mitigate.
