Kernrechtsfrage
Whether the defendant's request for security for costs was still admissible
Extrahierter Entscheid
The request had become moot because it was filed together with the response, so the procedural step it sought to avoid had already been taken.
Extrahierte Begründung
Security for costs is meant to prevent unnecessary expenses before the responding party acts. Since the respondent filed the request in the same submission as the response, no useful purpose remained.
