Key legal question
Whether the Federal Tribunal could review only the Federal Administrative Court's non-entry decision, not the merits of the AI pension dispute.
Extracted holding
The review was confined to the refusal to enter into the appeal; the merits request to keep the disability pension was inadmissible.
Extracted reasoning
The challenged judgment concerned only the non-entry based on failure to pay the advance; therefore the Federal Tribunal could not address the substantive pension claim.
