Questão jurídica principal
Whether the federal appeal was admissible only for constitutional violations under Article 98 LTF
Decisão extraída
The appeal was admissible only as to constitutional grievances; ordinary complaints about federal and Lugano Convention law were not reviewable.
Fundamentação extraída
A decision on opposition to arrest is a provisional measure within Article 98 LTF, so review is limited to constitutional rights and arbitrariness.
