Questão jurídica principal
Whether the complaint against the confirmed immigration detention was admissible despite lacking specific reasoning.
Decisão extraída
The filing was manifestly inadmissible because it did not engage with the challenged decision or explain any legal violation.
Fundamentação extraída
A public-law appeal must state requests and reasons and address the decisive considerations of the lower court; the appellant's letter did neither, so there was no basis to review the detention.
