Questione giuridica chiave
Whether the appeal against the procedural order fixing German as the language of the main hearing is admissible under Art. 93 BGG
Decisione estratta
The appeal is inadmissible because no irreparable legal harm is shown; any language-related objections can still be raised in an appeal against the final judgment.
Motivazione estratta
A fixed trial language does not, by itself, create a non-remediable disadvantage. The court noted the long-standing German-language conduct of the proceedings, the prior extensive use of translations, and the continued availability of necessary translations during trial.
