Key legal question
Whether the constitutional complaint could be entered into despite non-payment of the court cost advance within the extended deadline.
Extracted holding
No. Because the appellant did not pay the advance even during the grace period, the complaint had to be dismissed from consideration.
Extracted reasoning
Under Art. 62(3) BGG and in the procedure under Art. 108(1)(a) BGG, failure to pay the ordered advance within the additional deadline requires non-entry.
