Kernrechtsfrage
Whether the respondent's request for security for costs became moot after filing its appeal response
Extrahierter Entscheid
The request was moot because the respondent had already filed its written response and the costs were already incurred; court costs were also already secured by the appellant's advance payment.
Extrahierte Begründung
Security for costs protects against future costs only and cannot cover costs already incurred when the request is decided.
