Kernrechtsfrage
Whether the cantonal court wrongly refused to examine the pension claim for the period before October 2004 because of res judicata.
Extrahierter Entscheid
The Federal Supreme Court held that the new case law on partial decisions could not disadvantage the claimant; all complaint points had to be examined.
Extrahierte Begründung
Although the earlier cantonal ruling had partly decided the period up to 25 October 2004, the Court applied the later clarified rule on partial decisions in a manner consistent with good faith and declined to let the claimant suffer from the subsequent change in practice.
