Questão jurídica principal
Whether the appeal against detention-extension decisions was admissible and what parts were inadmissible.
Decisão extraída
The appeal was only admissible to the extent it challenged the detention decision; the request to annul the first-instance decision was inadmissible due to devolutive effect, and the request for a declaratory finding of a motivation defect was inadmissible.
Fundamentação extraída
The removal aspect falls outside federal appeal jurisdiction, and a purely preparatory or declaratory conclusion cannot be maintained where the lower instance issued a constitutive decision.
