Question juridique clé
Whether the psychiatric expert report was unusable because the expert's name was not timely disclosed under Art. 44 ATSG.
Solution extraite
The late disclosure infringed participation rights, but it caused no legally relevant prejudice; the report remained admissible because any challenge to the expert would have lacked prospects of success.
Motifs extraits
The expert had the required specialist title; no valid ground for challenge was shown, and the procedural defect was not serious enough to exclude the report.
