Questão jurídica principal
Whether the cantonal proceedings violated the appellant's right to be heard by failing to communicate later submissions before judgment.
Decisão extraída
Yes. The cantonal court relied on supplementary filings submitted shortly before judgment without formally inviting the appellant to comment.
Fundamentação extraída
Under Art. 29(2) Cst. and Art. 6 ECHR, every new submission or exhibit must be communicated so the parties can decide whether to comment. Prior informal exchanges do not replace a formal invitation from the court.
