Questione giuridica chiave
Whether the revision request was admissible despite non-payment of the ordered cost advance.
Decisione estratta
The court did not enter into the revision request because the applicants failed to pay the advance even within the extended deadline.
Motivazione estratta
Under Art. 62(3) BGG, failure to pay the required advance after a grace period leads to non-entry; the conditions for proceeding were therefore not met.
