Key legal question
Whether the constitutional complaint had to be declared inadmissible for failure to pay the advance of costs within the additional deadline.
Extracted holding
Yes. The advance of costs was not paid within the grace period, so the complaint was inadmissible under the Federal Supreme Court Act.
Extracted reasoning
After an initial deadline and a non-extendable additional deadline, non-payment of the advance triggers inadmissibility under Art. 62(3) LTF.
