Question juridique clé
Whether the subsidiary constitutional complaint met the strict reasoning requirements
Solution extraite
No. The complaint was merely appellatory and did not identify any constitutional violation with sufficient precision.
Motifs extraits
Under Arts. 42(1)-(2), 106(2), and 117 LTF, constitutional complaints require qualified reasoning; here the appellants invoked Art. 29 Cst. only in general terms and did not substantiate concrete legal guarantees or any cantonal rule.
