Questione giuridica chiave
Whether the appeal could be entered into despite non-payment of the court cost advance within the grace period.
Decisione estratta
No. The appeal could not be heard because the advance on costs was not paid within the non-extendable grace period.
Motivazione estratta
Under Art. 62 BGG, failure to pay the advance within the prescribed grace period leads to non-entry. A late, insufficiently substantiated request for legal aid does not preserve the deadline.
