Questão jurídica principal
Whether the federal appeal was admissible as a constitutional subsidiary appeal
Decisão extraída
The filing could only be treated as a subsidiary constitutional appeal, and it was inadmissible because it did not clearly invoke or substantiate any constitutional violation.
Fundamentação extraída
The value in dispute did not reach the threshold for an ordinary civil appeal and no fundamental legal question was involved. Under the subsidiarity regime, constitutional complaints require explicit identification and substantiation of the violated constitutional rights, which was absent.
