Questão jurídica principal
Whether the cantonal court rightly declared the appeal inadmissible for late payment of the advance on costs and rejected restitution of the time limit.
Decisão extraída
Yes. The appellant had to expect the notice and ensure receipt; his mother's failure to forward it was not a non-fault impediment.
Fundamentação extraída
Proper notification was valid when the registered mail was received at the address. The appellant could have informed himself before leaving. Late payment could not cure the missed deadline.
