Key legal question
Which authority is competent to decide the unsealing request in this mutual legal assistance case?
Extracted holding
The Federal Criminal Court's complaints chamber is competent to decide the unsealing request.
Extracted reasoning
Art. 9 sentence 2 IRSG refers to Arts. 246-248 StPO only subsidiarily; because no federal seizure court exists for this procedure and Art. 65 StBOG does not apply to the Federal Customs Administration, the VStrR remains applicable, which assigns such disputes to the Federal Criminal Court complaints chamber.
