Key legal question
Whether the Geneva cantonal social insurance court had territorial jurisdiction over the appeal against the accident-insurance opposition decision.
Extracted holding
No. Competence lay with the social insurance court of the insured's canton of domicile, which was Jura at the relevant time.
Extracted reasoning
Under Art. 58(1) LPGA in conjunction with Art. 1(1) LAA, the venue is the insurance court of the insured's domicile canton or of another party. The insurer is not 'another party' within that rule, nor are its agencies. The rule is mandatory and cannot be displaced by prior exchange of submissions.
