Question juridique clé
Whether the cantonal court had to grant a remedial period for the appeal under Art. 61 lit. b ATSG
Solution extraite
A remedial period had to be granted; no obvious abuse was shown.
Motifs extraits
The lawyer was retained shortly before the deadline, requested the file immediately, and could not reasonably file a fully reasoned appeal without the medical records. In such circumstances, a brief or missing justification does not by itself amount to abuse.
