Kernrechtsfrage
Whether parliamentary allowances count as income for disability assessment under Art. 16 LPGA.
Extrahierter Entscheid
Yes. The allowances were properly treated as earnings from gainful activity because the parliamentary mandate was stable, remunerated, and fully used the remaining work capacity.
Extrahierte Begründung
A post-onset activity qualifies as invalid income if it is stable, exploits residual capacity, and corresponds to actual work without social wage elements. Parliamentary remuneration is comparable to salary of public officials and therefore falls within income under Art. 16 LPGA.
