Question juridique clé
Whether the appeal was admissible absent a decision on opposition or another appealable decision.
Solution extraite
The appeal was inadmissible because the appellant challenged a letter of 12 October 2012 rather than an appealable opposition decision.
Motifs extraits
Under Art. 52(1) LPGA, administrative decisions must first be contested by objection unless the objection route is unavailable; under Art. 56(1) LPGA, only opposition decisions or decisions not subject to objection are appealable. The challenged correspondence was not such a decision.
