Questione giuridica chiave
Whether the appeal had to be declared inadmissible because the advance of costs was not paid on time and no timely waiver or legal-aid step was requested.
Decisione estratta
The appeal had to be declared inadmissible; the appellant had been duly warned, the advance was not paid within the deadline, and no timely request for waiver or legal aid was filed.
Motivazione estratta
Under the cantonal procedure rules applicable to social-insurance appeals, an advance of costs may be required and non-payment after due warning leads to non-entry. The appellant only sought a postponement after expiry of the deadline and did not timely request exemption or legal aid.
