Question juridique clé
Whether the constitutional complaint against the order to pay a cost advance was admissible
Solution extraite
The complaint was admissible as a separately notified interim decision because the cost-advance order threatened a non-reparable disadvantage if non-payment would lead to non-entry.
Motifs extraits
A cost-advance order coupled with a threat of dismissal for non-payment is an appealable interim decision under the applicable procedural law.
