Question juridique clé
Whether the complaint against the cantonal supervisory decision could be heard despite the challenge being limited to factual and evidentiary assessment.
Solution extraite
The complaint was inadmissible to the extent it challenged the cantonal authority's factual findings and anticipatory assessment of evidence, because such issues could not be reviewed in this procedure.
Motifs extraits
The Federal Court is bound by the cantonal finding that the rekurs did not allege a material effect on the expert valuation. Attacks on that finding and on the authority's anticipatory evaluation could only be raised by constitutional complaint, not under Art. 19 SchKG.
