Questione giuridica chiave
Whether the refusal to order further handwriting expertise and allow access to dossier pieces caused irreparable harm justifying immediate federal appeal
Decisione estratta
No irreparable legal harm was shown; the evidentiary issues could be raised again later.
Motivazione estratta
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.
