Kernrechtsfrage
Whether the subsidiarity constitutional complaint is admissible despite non-payment of the court advance within the granted grace period.
Extrahierter Entscheid
The complaint is inadmissible because the advance was neither paid in cash nor timely credited with the required proof of payment.
Extrahierte Begründung
After the refusal of legal aid for lack of prospects, the complainant was granted a non-extendable 10-day grace period under Art. 62 para. 3 BGG and warned of non-entry. She did not comply and did not provide the required bank/postal debit confirmation, so non-entry follows under the Federal Supreme Court Act.
