Questão jurídica principal
Which income period governs entitlement to family supplementary benefits under § 81bis SG / § 85bis SG?
Decisão extraída
The prior year is the starting point, but a temporary shortfall during the benefit year does not automatically end entitlement.
Fundamentação extraída
Family supplementary benefits are based primarily on the preceding year's income, yet the statute's purpose and the wording requiring income to be 'earned' during the period exclude a rigid monthly twelfth-by-twelfth test. A temporary drop only matters if it is likely to last longer; the court applies by analogy the concepts of Art. 88a IVV.
