Kernrechtsfrage
Whether the appeal was admissible insofar as it sought a half pension from 1 November 2007
Extrahierter Entscheid
The appeal was inadmissible in that respect because a half pension had already been granted for that period, so there was no legal interest in challenging it.
Extrahierte Begründung
A challenge requires a concrete grievance; where the requested relief has already been granted, the appellant lacks standing for that part of the appeal.
