Questione giuridica chiave
Whether the federal appeal was admissible after the appellant had renounced the cantonal appeal
Decisione estratta
The appellant could not validly withdraw his renunciation absent any allegation or proof of vitiated consent or incorrect judicial information; any later confirmation was ineffective.
Motivazione estratta
Renunciation of a legal remedy is not freely revocable. Nothing showed a defect of will or misleading official information, so the appellant lacked standing to return to the earlier appeal.
