Motifs extraits
For AI office decisions, the special and exclusive forum is the social insurance court at the seat of the competent cantonal AI office. The insured was domiciled in Fribourg when the application was filed, so Fribourg remained competent throughout the proceedings under Art. 40 para. 3 RAI.
