Questão jurídica principal
Whether the cantonal court complied with the Federal Court's remittal instructions and could rely on the RAD psychiatrist's statement without further expert questions.
Decisão extraída
The cantonal court sufficiently complied with the remittal order and could, in its discretion, forgo supplementary questions and rely on the RAD psychiatrist's statement.
Fundamentação extraída
The remittal decision only required further clarification; the lower court was free in how to conduct it. The criticism of the RAD doctor's neutrality and probative value was not persuasive.
