Key legal question
Whether the complaint against the cost-advance interim order was sufficiently reasoned under Art. 42 BGG.
Extracted holding
No. The filing did not explain in a legally reasoned way why the cost advance violated federal law.
Extracted reasoning
Although appeals against separate interim decisions on cost advances may in principle be admissible, the appellant must still set out specific requests and reasons. He merely claimed the proceedings should be free of charge and did not address why a reimbursable cost advance would be unlawful.
