Question juridique clé
Whether the repayment waiver conditions under supplementary benefits law were met, especially good faith.
Solution extraite
The case must be remanded because the cantonal court denied good faith on a substituted reason without hearing the parties on that point.
Motifs extraits
The cantonal court relied on the claimant’s alleged duty to alert the administration to its own calculation error, but this issue had not been discussed; substituting a decisive ground without prior hearing violates the right to be heard.
