Question juridique clé
Whether Art. 69 para. 1bis LAI directly authorizes cantonal court costs in AI disputes despite the general rule of free proceedings in Art. 61 let. a LPGA.
Solution extraite
Yes. Art. 69 para. 1bis LAI directly derogates from the free-of-charge rule and allows court costs without additional cantonal implementation.
Motifs extraits
Federal law prevails over cantonal silence under Art. 49 para. 1 Cst. The federal provision intentionally makes AI appeal proceedings chargeable and applies to all parties, with costs normally borne by the losing party.
