Question juridique clé
Whether the public-law appeal remained admissible despite expiry of the three-month deadline for registering a building lien.
Solution extraite
No. Once the peremptory deadline had expired and the reduced registration had already been executed, annulling the cantonal order could no longer restore the requested higher lien amount.
Motifs extraits
The appeal lacked a current and practical interest under Art. 88 OJ because the lien amount could not be increased after the expiry of Art. 839 para. 2 CC. The earlier superprovisional registration did not help once the provisional order reducing the amount had been implemented.
