Decisione estratta
The appeal did not specifically show that the lower court's factual findings were manifestly incorrect or legally defective.

The Federal Court is bound by the lower court's facts unless a proper challenge under Art. 97 and 105 BGG is made. The appellant merely disputed the facts and did not address the decisive legal question of liability until valid deregistration.
