Questão jurídica principal
Whether the municipality had standing to appeal the EL decision in its own financial interest
Decisão extraída
Yes. Because the municipality had advanced uncovered care and living costs, it had a specific financial interest and could challenge the decision.
Fundamentação extraída
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.
