Kernrechtsfrage
Whether the old-age pension had to be increased by correcting the individual account for 1979-1981
Extrahierter Entscheid
No. The available account records did not prove that contributions had been deducted from wages or that a net-wage agreement existed; therefore no correction was warranted.
Extrahierte Begründung
A correction of the individual account requires full proof of one of the legally recognized grounds. The claimant failed to prove either wage deductions or a net-wage arrangement, and the burden of proof fell against him because he relied on the unproven fact to derive rights.
