Question juridique clé
Whether the federal debt-enforcement complaint was admissible despite the applicant not challenging both independent grounds of the cantonal decision.
Solution extraite
The complaint was inadmissible insofar as the appellant failed to address the second, independent ground of the cantonal decision, which alone justified dismissal.
Motifs extraits
Where a decision rests on two independent reasons, the complaint must attack both. The appellant did not show any violation of federal law regarding timeliness or restoration of time limits, and the factual assertion of later knowledge could not be considered.
