Question juridique clé
Whether the tenants' association had standing to file a public-law appeal against the authorization to sell the apartment.
Solution extraite
The association did not establish that it was directly affected, that the decision affected a large enough number of its members individually, or that it could bring a corporate appeal; it therefore lacked standing.
Motifs extraits
Under Art. 89 LTF, an association may appeal only if it is itself affected or meets the strict requirements for an association appeal. A mere interest in correct application of the law is insufficient, and the association did not show a formal denial of justice either.
