Key legal question
Whether the appeal was admissible despite non-payment of the required advance on costs.
Extracted holding
No. The appellant neither paid the advance nor produced proof that the required amount had been debited from a postal or bank account.
Extracted reasoning
Under Art. 48(4) LTF, payment must be proven; failure to do so after the warning and additional deadline leads to inadmissibility under Art. 62(3) LTF.
