Whether the prosecutor's appeal regarding the costs imposed on P.________ and Z.________ should be upheld after the Federal Tribunal's rulings.
The appeal had to be rejected as to P.________ and Z.________ because the Federal Tribunal itself had held that the cost allocation against them was unjustified.
Under Art. 107(2) LTF, after allowing a recourse the Federal Tribunal may decide the merits itself or remit the case. Since it had already decided that the costs could not be charged to P.________ and Z.________, the cantonal court had no basis to depart from that conclusion.
