Key legal question
Whether the complaint had to be entered into despite non-payment of the court advance.
Extracted holding
No. After the advance was set, a non-extendable grace period expired without payment, so the Court did not enter into the complaint.
Extracted reasoning
Under Art. 62 BGG, the party bringing the case must pay an advance on costs. If the advance is not paid within the set period and grace period, the Federal Supreme Court may not proceed to the merits; here no valid reason excused the failure, especially after legal aid was refused for lack of proof of indigence.
