Key legal question
Whether the revision request was admissible despite non-payment of the advance on costs within the extended deadline.
Extracted holding
No. Because the applicants failed to pay the advance on costs within the grace period, the revision request was inadmissible under Art. 62 para. 3 LTF.
Extracted reasoning
The court had first set an initial deadline and then, after non-payment, granted a non-extendable additional deadline. The recommended mail containing that order was not collected, but the advance still was not paid by the end of the second deadline.
