Questão jurídica principal
Whether the appeal against the cost-advance order was admissible as a separate appeal against an interim decision.
Decisão extraída
Yes. An order requiring an advance payment can be separately challenged because non-payment may lead to non-entry and thus cause irreparable harm.
Fundamentação extraída
The court relied on the rules governing appealability of interim decisions and noted that the authority had threatened non-entry if the advance was not paid.
