Question juridique clé
Admissibility of the federal appeal against the lower supervisory decision and the auction itself
Solution extraite
The appeal was inadmissible because it challenged a non-final cantonal decision, attacked the completed auction although only the supervisory decision could be reviewed, and did not show current legal interest.
Motifs extraits
Federal appeals lie only against final cantonal decisions; the appellant failed to demonstrate standing and a current practical interest after the auction had already occurred. No exception to the current-interest requirement was shown.
