Questão jurídica principal
Whether the appeal had to be entered into despite non-payment of the advance on costs.
Decisão extraída
No. Because the appellant failed to pay the advance within the set deadline and did not seek an extension or legal aid, the appeal was inadmissible.
Fundamentação extraída
Under the applicable social-insurance and cantonal procedural rules, the appellant had been warned of the consequence of non-payment; absent payment or a timely request for extension, the court had to decline to enter into the appeal.
