Question juridique clé
Whether the auction was invalid because the last bid was not cried three times.
Solution extraite
The auction was valid; the cantonal authority could rely on evidence showing that the final bid was cried three times and no higher bid was made.
Motifs extraits
The auction record is a public document with rebuttable evidentiary force. Its inaccuracy may be proven by any means, including witness testimony. The assessment of that evidence is a matter of proof evaluation, which the Federal Tribunal does not review here.
