Questão jurídica principal
Whether the appeal should be considered despite late supplementary filings and unsubstantiated references to cantonal submissions.
Decisão extraída
The supplementary submissions were out of time and could not be considered; references to cantonal pleadings were likewise inadmissible.
Fundamentação extraída
The federal appeal deadline had expired, and submissions from the cantonal proceedings do not satisfy the duty to challenge the appealed judgment specifically.
