Questione giuridica chiave
Whether the Federal Supreme Court could entertain the complaint despite non-payment of the advance costs within the extended deadline.
Decisione estratta
The complaint could not be entertained because the required advance costs were not paid even after the grace period.
Motivazione estratta
Under Art. 62(3) BGG, failure to pay the requested advance costs within the set time limit permits non-entry; the case was therefore decided summarily under Art. 108(1)(a) BGG.
