Kernrechtsfrage
Whether the refusal to order further handwriting expertise and allow access to dossier pieces caused irreparable harm justifying immediate federal appeal
Extrahierter Entscheid
No irreparable legal harm was shown; the evidentiary issues could be raised again later.
Extrahierte Begründung
The refused evidence could be requested again at later procedural stages and on appeal; the alleged loss of evidence was speculative, and the retained documents stayed in the file until final judgment.
