Kernrechtsfrage
From which date must the hypothetical income be excluded from the supplementary benefits calculation?
Extrahierter Entscheid
The authority could not be compelled to reconsid er its final decision on a different ground; exclusion of the hypothetical income was only to be recalculated from 1 January 2009.
Extrahierte Begründung
The cantonal court extended the scope of reconsidération beyond the ground actually examined by the authority. In the absence of a specific legal basis, a judge may not impose a reconsidération on another ground or prescribe its modalities.
