Questione giuridica chiave
Whether the filing could be treated as a civil appeal or only as a subsidiary constitutional complaint.
Decisione estratta
The ordinary civil appeal was unavailable because the amount in dispute was below the statutory threshold and no fundamental legal question was shown; the filing was treated as a subsidiary constitutional complaint.
Motivazione estratta
The dispute concerned a public-law fee connected with civil law, but the value requirement of Art. 74 BGG was not met and no reason for exceptional admissibility was alleged.
