Kernrechtsfrage
Whether documented expenses from self-employed interim earnings must be deducted beyond the 10% BIGA cap.
Extrahierter Entscheid
Documented non-investment expenses must be deducted even if they exceed 10% of gross income; the BIGA cap has no legal basis.
Extrahierte Begründung
Art. 24 AVIG covers self-employed interim earnings, but the statute and AVIV do not regulate expenses. BIGA guidelines are not binding and cannot restrict deductible expenses without a legal basis. Administrative convenience cannot justify refusing higher proven non-investment expenses.
