Question juridique clé
Whether the Federal Administrative Court correctly declared the administrative appeal inadmissible despite a signed request for annulment and a brief motivation.
Solution extraite
The appeal filing contained sufficient minimum indications of a request to challenge the decision and to seek its modification; after the curing period expired without further action, the court should have decided on the basis of the file rather than declaring the appeal inadmissible.
Motifs extraits
Art. 52 PA requires conclusions, reasons and evidence, but only a minimum of formal care; where a signed filing expresses the will to appeal and gives at least a brief reason, the authority must proceed on the merits if defects are not cured, provided the party was warned of the consequences.
