Key legal question
Whether the cantonal court acted arbitrarily by relying on amended psychiatric expert reports without further clarification.
Extracted holding
Yes. The later addenda were based essentially on an unverified phone call and contained obvious substantive and procedural shortcomings; the court had to obtain a supplementary or superior expert opinion.
Extracted reasoning
The court stressed that it should not depart from expert medical assessments without compelling reasons, but here the addenda were not sufficiently reliable. They were founded on a foreign anamnesis without procedural safeguards and were internally and externally inconsistent with other reports in the file.
