Key legal question
Whether the complaint against the interlocutory order on the language of the main hearing was admissible under Art. 93 BGG.
Extracted holding
The complaint was inadmissible because no irreparable legal disadvantage was shown and the conditions for direct review of an interlocutory decision were not met.
Extracted reasoning
The court held that continued use of German did not prevent adequate translation or later review of any language-related grievances in an appeal against the final judgment.
