Questão jurídica principal
Whether the federal appeal could challenge only the cantonal non-entry decision and not the merits of the IV dispute.
Decisão extraída
Only the refusal to enter could be reviewed; the Federal Court could not examine the substantive requests directed against the IV decision itself.
Fundamentação extraída
When the lower court issues a non-entry order without an alternative merits ruling, the object of the federal appeal is solely that non-entry order.
