Questione giuridica chiave
Whether the refusal to extend the response deadline in the mainlevée proceedings was arbitrary or violated the right to be heard.
Decisione estratta
The refusal was not arbitrary and did not violate the right to be heard because the applicant had not made the alleged complexity of the case plausible as a sufficient reason.
Motivazione estratta
Art. 144(2) CPC grants no automatic extension right; a party must invoke sufficient reasons. The cantonal court reasonably found no plausible reason and could also consider the summary nature and required speed of definitive mainlevée proceedings.
