Kernrechtsfrage
Whether the appellant could again challenge the imputed rent of CHF 1,383 despite a final earlier decision limiting it to CHF 1,000.
Extrahierter Entscheid
That issue was not open in this proceeding because no actionable subject existed; the rent question had already been finally decided.
Extrahierte Begründung
A higher rent allowance had to be requested first from the social authority after a change in circumstances; the appellant could not reopen the finalized rent question within the pending appeal about third-party income.
