Key legal question
Whether the appeal could be heard despite non-payment of the court advance within the deadline
Extracted holding
The appeal could not be examined and was not entered into because the advance was not paid on time after proper warning.
Extracted reasoning
The appellant failed to collect the court orders but they were additionally served by ordinary mail; a party seising the Federal Court must ensure that judicial mail reaches them. Since the advance was not paid within the extended deadline, non-entry followed under Art. 108 BGG.
