Question juridique clé
Whether the subsidiarity constitutional complaint against the cantonal order was admissible despite challenging the first-instance foreclosure decision and the earlier advance-payment request.
Solution extraite
The complaint was inadmissible insofar as it attacked the first-instance foreclosure decision and the earlier advance-payment request; only the final cantonal decision could be challenged.
Motifs extraits
A subsidiarity constitutional complaint may only be directed against final cantonal decisions; earlier procedural steps or first-instance judgments are not directly reviewable.
