Question juridique clé
Whether the respondent proved entitlement to compensation for family care by her sister under Art. 13 Abs. 5 ELKV.
Solution extraite
No entitlement was proven because an actual loss of earnings by the caregiving sister was not established.
Motifs extraits
The burden of proof lay with the claimant; statistical income fluctuations did not show a concrete earnings loss attributable to care, and the sister's actual employment and income situation were not sufficiently substantiated.
