Questão jurídica principal
Whether the appeal against the interim decision refusing legal aid and ordering an advance on costs was admissible
Decisão extraída
The interim decision was appealable because refusal of the cost advance could cause irreparable harm by preventing the case from proceeding.
Fundamentação extraída
The matter concerned public law; no statutory exception applied; and the threatened loss of the case if the advance was not paid constituted irreparable prejudice.
