Question juridique clé
Whether the state-law complaint was admissible against the cantonal remand order to issue an heir certificate
Solution extraite
The complaint was admissible because the remand left no discretion and amounted to mere execution.
Motifs extraits
An order for issuance of an heir certificate is an act of voluntary jurisdiction; the remand was therefore a final, reviewable decision rather than a non-appealable remand.
