Key legal question
Whether the cantonal supervisory commission abused its discretion by preferring the second appraisal over the first for the pledged property's valuation.
Extracted holding
No. The second appraisal followed the then-applicable SIA 416 standard and used more realistic parameters; the first appraisal relied on an obsolete standard and contained unexplained inconsistencies.
Extracted reasoning
In valuation matters the Federal Tribunal intervenes only for procedural violations or abuse/excess of discretion. Choosing the appraisal based on the current standard and more realistic assumptions was not arbitrary, and the appellants failed to show inappropriate criteria.
