Kernrechtsfrage
Whether the appeal materials filed on 2013-12-17 were admissible.
Extrahierter Entscheid
They could not be considered because they were filed after the appeal deadline and were new evidence not justified by the prior judgment.
Extrahierte Begründung
Late submissions and exhibits are excluded; the instance-specific new-evidence ban applied because the appellate judgment did not itself prompt the filing.
