Kernrechtsfrage
Whether the municipality had standing to appeal the EL decision in its own financial interest
Extrahierter Entscheid
Yes. Because the municipality had advanced uncovered care and living costs, it had a specific financial interest and could challenge the decision.
Extrahierte Begründung
Third-party standing requires a concrete and direct interest. A municipality that bears costs potentially covered by supplementary benefits may invoke its own financial interest and is not merely acting in the public interest.
