Kernrechtsfrage
Whether the order requiring the complainant to provide process cost security was open to complaint and whether the appeal period had run without legal notice.
Extrahierter Entscheid
The order was subject to complaint, and because no appeal notice was given, the complaint period did not start to run.
Extrahierte Begründung
A complaint remedy was not excluded by law and satisfied the statutory requirements; without notification of the remedy, the time limit could not begin.
