Kernrechtsfrage
Whether the insured earnings for the survivor's pension were correctly fixed or required further factual clarification on the outbreak of the occupational disease.
Extrahierter Entscheid
The current file did not allow a reliable determination of when the occupational disease had broken out; further investigations were required before the pension entitlement could be newly decided.
Extrahierte Begründung
The medical and administrative records indicated respiratory problems before 27 January 2005, but it remained unclear whether these already impaired work capacity and thus brought forward the outbreak date. If the outbreak predated January 2005, parts of the earnings period might fall before the invalidity pension started and could trigger the special rule on reduced earnings; if not, the general rule applied.
