Key legal question
Whether the appellant's bias allegation against the justice of peace was admissible before the Federal Court
Extracted holding
The bias argument was inadmissible because it was a new ground not shown to have been raised before the cantonal court.
Extracted reasoning
The file did not show that the appellant invoked bias in the appeal to the Chamber des tutelles, and he did not demonstrate having raised that exception there. New arguments are barred by Art. 99 LTF.
