Questão jurídica principal
Whether the action could be entered into despite non-payment of the advance on costs after expiry of the extended deadline.
Decisão extraída
No entry could be made because the plaintiff failed to pay the advance on costs within the non-extendable grace period.
Fundamentação extraída
Under Art. 62(1) and 62(3) BGG, the party seizing the Federal Supreme Court must pay an advance on costs; if it is not paid within the set time limit and grace period, the court does not enter into the filing. The plaintiff's later letters did not alter this consequence.
