Kernrechtsfrage
Whether Art. 165 Abs. 2 HRegV validly requires a single cantonal court as sole appeal instance in commercial register matters
Extrahierter Entscheid
Yes. Art. 929 Abs. 1 OR empowers the Federal Council to regulate the appeal procedure, including the cantonal instance chain, and this is compatible with Art. 75 Abs. 2 BGG.
Extrahierte Begründung
The wording of Art. 929 Abs. 1 OR is broad; the legislative history shows an intentionally very wide delegation; neither Art. 927 Abs. 3 OR nor Art. 122 BV prevents such regulation, and the BGG double-instance principle only requires access to an upper cantonal court, not a two-step cantonal appeal path.
