Question juridique clé
Whether the public-law appeal against the cantonal mainlevée decision was admissible
Solution extraite
The appeal was not admissible because the arguments were merely appellatory and did not show arbitrariness in the cantonal reasoning.
Motifs extraits
In a public-law appeal, only clearly and specifically argued constitutional grievances are examined. The appellant did not challenge the actual reasoning that its own letter showed a waiver of the arrears, but instead advanced a different view of the file.
