Question juridique clé
Whether the federal appeal was admissible despite only challenging the factual findings and relying on new evidence.
Solution extraite
The appeal was inadmissible because the appellant did not show arbitrariness in the findings below and the new employer confirmation was an inadmissible late piece of evidence.
Motifs extraits
Factual findings can only be attacked by a precise arbitrariness complaint under Art. 97(1) and 106(2) BGG. The confirmation dated 5 April 2013 was new evidence and could have been filed earlier in the cantonal appeal; Art. 99(1) BGG did not permit it.
