Questione giuridica chiave
Whether the federal appeal against the cantonal detention decision was sufficiently reasoned under the LTF.
Decisione estratta
The filing did not meet the required reasoning standards because it cited no federal or cantonal rule and did not address the cantonal court's reasoning.
Motivazione estratta
When a challenge concerns cantonal criminal procedure, constitutional rights must be invoked and the appeal must explain clearly and precisely why the decision violates them; this was not done.
