Questão jurídica principal
Whether the appeal was admissible despite being directed against an incidental detention decision and despite largely abstract requests.
Decisão extraída
Only the challenge to the concrete refusal to prolong detention was admissible; requests seeking general abstract rules were inadmissible.
Fundamentação extraída
The Federal Court does not issue general directives detached from the specific case, and the appellant lacked a practical and current interest in abstract questions.
