Key legal question
Whether the constitutional complaint could be entered into despite non-payment of the required court cost advance within the extended deadline.
Extracted holding
The complaint was not entered into because the advance payment was not made even by the extended deadline.
Extracted reasoning
Under Art. 62 para. 3 BGG and the summary procedure of Art. 108 para. 1 lit. a BGG, failure to pay the requested advance justifies non-entry.
