Kernrechtsfrage
Whether the cantonal court acted arbitrarily by refusing late documents and evidence in appeal proceedings.
Extrahierter Entscheid
No arbitrariness was shown; the submissions were late and did not satisfy the strict statutory exceptions for new facts or evidence.
Extrahierte Begründung
The documents were not filed in time, their correctness did not clearly follow from the file, the opponent disputed them, and their content was not self-evidently established by documents.
