Questão jurídica principal
Whether the respondent could still request security for costs after having already filed its response.
Decisão extraída
A respondent must request security for costs before taking any step on the merits before the Federal Court; the request came too late.
Fundamentação extraída
Under the settled case law applied to Art. 62(2) LTF, a party loses the right to seek security once it has already proceeded in the case.
