Key legal question
Whether the complaint could be entered into despite non-payment of the advance costs within the deadline.
Extracted holding
No entry was possible because the advance costs were not paid and no timely proof of debit was provided.
Extracted reasoning
After a prior reminder under Art. 62(3) BGG and an express warning of non-entry, the appellant neither paid the advance in cash nor through the permitted postal/bank transfer method, nor submitted the required debit confirmation.
