Questão jurídica principal
Whether the appeal against a remand judgment was admissible.
Decisão extraída
The remand decision contained binding substantive instructions and therefore caused a legally relevant disadvantage; the appeal was admissible.
Fundamentação extraída
A remand order is generally interlocutory, but it is appealable when it constrains the lower court by substantive findings so that a potentially unlawful new decision would have to be issued.
