Question juridique clé
Whether the insured person was entitled to party compensation before the cantonal court despite losing the merits because the IV office caused a hearing violation.
Solution extraite
No party compensation was owed, because the violation did not cause additional costs; the claimant would have appealed even if the medical reports had been disclosed earlier.
Motifs extraits
Costs are shifted only for expenses caused by the opposing party. Since the claimant continued to contest the medical opinions and would have filed the appeal in any event, no compensable extra costs resulted from the hearing defect.
