Questão jurídica principal
Whether the appeal against the stay order was immediately admissible as an incident on jurisdiction/litispendence
Decisão extraída
Yes. The stay order was an incidental decision on a question of competence under art. 92(1) LTF and could be appealed immediately.
Fundamentação extraída
The order did not end the case, but it resolved whether the French court, as first seised, had to decide its own competence under art. 21 CL; that qualifies as a competence issue.
