Kernrechtsfrage
Whether the late-filed private expert report and related reimbursement request had to be admitted
Extrahierter Entscheid
The private report was an inadmissible new piece of evidence; no reimbursement of its costs was owed.
Extrahierte Begründung
Even assuming new evidence may in principle be filed, the conditions for late submission after the appeal deadline were not met because the report did not justify revision-type grounds and lacked procedural admissibility.
