Key legal question
Whether the appeal satisfied the formal requirements of Art. 42 LTF.
Extracted holding
The appeal did not set out admissible conclusions or sufficient reasoning and was therefore inadmissible.
Extracted reasoning
The appellant only alleged a worsening of health and payment of AVS/AI contributions, without explaining why the cantonal findings were manifestly incorrect or unlawful, despite a prior warning and the limited review of facts under Arts. 97(1) and 105(2) LTF.
