Whether prepayment under Art. 26(4) BVG requires a materially established entitlement to invalidity benefits under Art. 23(a) BVG.
Yes. Prepayment presupposes that an invalidity benefit claim under occupational pension law exists; only the liable pension institution remains unclear.
The wording of Art. 26(4) BVG, the legislative history, and the insurance principle require a substantive preliminary review of entitlement under Art. 23(a) BVG. A mere theoretical possibility is insufficient.
