Questão jurídica principal
Whether the subsidiary constitutional complaint was admissible despite the low amount in dispute and the municipality's standing.
Decisão extraída
Yes. The amount in dispute did not reach the Berufung threshold, and the municipality could invoke constitutional rights as a party affected in its legally protected interests.
Fundamentação extraída
The claim was a civil dispute below the Berufung value, making the subsidiary constitutional complaint available; as subrogated creditor in child-support enforcement, the municipality acted on a private-law basis and could complain like a private person.
