Questão jurídica principal
Whether the appeal had to be entered into despite non-payment of the advance on costs.
Decisão extraída
No. The advance-on-costs order was deemed validly served, and failure to pay within the deadline required non-entry.
Fundamentação extraída
After a procedural relationship is established, the party must ensure it can receive court mail. The company had changed or abandoned its address and could not be reached at the Swiss address given; the later Prague address could not validly serve as a foreign service address. Under the applicable rules, the service was deemed valid, so the sanction under Art. 150 OG applied.
