Key legal question
Whether the appeal against the federal criminal court's cost order was admissible although it concerned only costs after the seizure complaint became moot.
Extracted holding
The appeal was admissible because the cost decision was accessory to an appealable coercive measure, namely the seizure.
Extracted reasoning
A costs ruling alone would not normally qualify as a coercive measure, but where it is incidental to a decision on an appealable seizure order, federal review is open.
