Key legal question
Whether the children had standing to appeal in their own name
Extracted holding
The children did not automatically have standing; they had to show a concrete protected interest. The Court left open whether they had such an interest because the mother clearly had standing.
Extracted reasoning
Under Art. 59 LPGA and Art. 89(1) LTF, family relationship alone no longer suffices; the previous jurisprudence under former Art. 84 LAVS cannot be maintained.
