Question juridique clé
Whether the cantonal procedure could lawfully require an advance of costs in AI disputes
Solution extraite
Yes. Under federal law, cantons may provide for court costs and may regulate an advance on costs in formal law.
Motifs extraits
Art. 69(1bis) LAI makes AI appeal proceedings subject to court costs; absent federal regulation of advances, cantonal law may provide for them, but the system must be set in formal law.
