Question juridique clé
Whether the filed constitutional complaint must be treated as a public law appeal.
Solution extraite
Yes. Because the dispute concerns a building permit in public law and no exclusion ground applied, the filing was to be treated as a public law appeal.
Motifs extraits
A constitutional complaint is subsidiary; in public law matters the ordinary public law appeal is available unless an exception applies. The fact that only the cost decision is challenged does not change that characterization.
