Kernrechtsfrage
Whether the constitutional appeal was sufficiently reasoned to be admissible.
Extrahierter Entscheid
The appeal was not reasoned in a manner that met the statutory requirements because it did not address the cantonal court's threefold reasoning.
Extrahierte Begründung
The appellant merely listed alleged defects in the invoice and failed to attack each independent ground of the cantonal decision; the submission was therefore manifestly insufficient under the applicable Federal Supreme Court pleading requirements.
