Questione giuridica chiave
Whether the renewed claim for pension benefits and interest for 1 March 2006 to 12 February 2007 was barred by res judicata.
Decisione estratta
Yes. That period was already finally decided in the 20 August 2007 Federal Supreme Court judgment, so the cantonal court should not have entered into the claim again.
Motivazione estratta
The earlier judgment had conclusively fixed the pension entitlement up to 12 February 2007. Res judicata covers the whole dispute period in a continuous benefit relationship, not only expressly discussed questions.
