Key legal question
Whether the unemployment fund could retroactively reduce insured earnings based on the IV invalidity degree
Extracted holding
The insured earnings may be adjusted to residual earning capacity under Art. 40b AVIV, but the fund must first examine whether the insured's earning capacity had in fact improved after the IV decision.
Extracted reasoning
Art. 40b AVIV is not limited to coordination with an actual IV pension; it generally limits unemployment insurance liability to the loss arising from the insured's remaining earning capacity. However, the IV denial itself is only a new fact if it may support a revised assessment, and here the period after the IV decision had to be assessed separately.
