Questão jurídica principal
Whether claims for a cost-of-living adjustment of old-age pensions belong under Art. 73 BVG rather than supervisory complaint proceedings.
Decisão extraída
The claim concerns a benefit entitlement inseparably linked to the old-age pension and must be brought before the pension courts under Art. 73 BVG.
Fundamentação extraída
A retroactive and future Teuerungsausgleich is a benefit tied to the pension right and does not form an independent substantive claim; therefore the judicial route under Art. 73 BVG applies.
