Key legal question
Whether the constitutional complaint could be entered into despite non-payment of the required cost advance after the grace period.
Extracted holding
No; the complaint could not be entered into because the required advance was not paid within the extended deadline.
Extracted reasoning
Under Art. 62(3) BGG, failure to pay the requested advance within the set time limit permits non-entry; the court therefore applied the summary non-entry procedure under Art. 108(1)(a) BGG.
