Kernrechtsfrage
Whether the arbitration court's letter of 29 February 2008 was a separately appealable incidental decision.
Extrahierter Entscheid
No. It was only an informational communication on how the court would continue taking evidence, without separate formal decision quality or appeal instructions.
Extrahierte Begründung
It did not concern jurisdiction or recusal, was not capable of causing irreparable harm, did not immediately lead to a final decision avoiding costly proof, and lacked sufficient motivation and appeal information.
