Key legal question
Whether the federal reform appeal was admissible against the Geneva decision ordering resumption of the proceedings by A and B.
Extracted holding
The decision was neither final nor partly final, and the strict conditions for an immediate appeal against an incidental decision were not met.
Extracted reasoning
The cantonal ruling did not refuse to decide the substantive claim; it merely allowed the succession-based resumption of the pending case. Any objections to party status or heir status could be raised later against the final judgment.
