Key legal question
Whether the constitutional appeal was admissible despite non-payment of the required advance of costs.
Extracted holding
No. Because the required advance was not paid within the time limits granted, the appeal had to be declared inadmissible.
Extracted reasoning
The appellant failed to pay the advance of costs first within the initial deadline and then within the extended deadline granted under Art. 62 para. 3 LTF; under Art. 108 para. 1 lit. a LTF the President could therefore not enter into the appeal.
