Questione giuridica chiave
Whether refusal to attend the ordered psychiatric reassessment justified denial of the invalidity insurance claim under Art. 43(3) ATSG.
Decisione estratta
The refusal constituted an inexcusable breach of the duty to cooperate, and without the reassessment the entitlement to benefits could not be examined reliably.
Motivazione estratta
The reassessment remained necessary to determine whether the insured actually suffered from a psychiatric illness. The file did not permit a reliable assessment, and later medical reports did not eliminate the need for the expert examination.
