Questão jurídica principal
Whether the cantonal court violated the right to be heard or fair trial by not inviting a reply to the respondent's observations on the revision request
Decisão extraída
No violation: the observations were sent for information under the ordinary written exchange, and the appellant could have reacted promptly but did not.
Fundamentação extraída
A party receiving observations without a formal invitation is still expected to seek or file a response without delay if it considers one necessary; the court's refusal to admit an unfiled response because of lack of standing did not cut off the hearing right.
