Kernrechtsfrage
Whether the departmental decision to treat the appeal as withdrawn and close the file was lawful
Extrahierter Entscheid
The withdrawal was unconditional and final; the department was not required to reopen the case.
Extrahierte Begründung
An unconditional withdrawal ends the appeal proceedings and makes the challenged decision final. No circumstances showed mistake, misleading conduct by the authority, or a ground requiring reversal of the withdrawal.
