Key legal question
Whether a nullity complaint was admissible against the labor court's preparatory order mentioning subject-matter jurisdiction
Extracted holding
No. The challenged act was an evidence-management order and not a separate decision on jurisdiction; that question would be decided with the merits and could then be appealed.
Extracted reasoning
A nullity complaint against jurisdiction is available only if the issue was decided separately by the last cantonal instance. Under the Geneva labor court system, the refusal of an incompetence objection is not decided independently during the proceedings but only in the merits judgment, which remains appealable at cantonal level.
