Kernrechtsfrage
Whether revision under Art. 121 let. d LTF was warranted because the court allegedly overlooked a relevant filing.
Extrahierter Entscheid
The omitted letter was not a pertinent fact within the meaning of Art. 121 let. d LTF, and even if considered, the outcome would have been the same.
Extrahierte Begründung
The second letter was unclear, lacked conclusions and the challenged cantonal decision, and did not satisfy the motivation requirements of Arts. 116, 106(2) and 117 LTF.
