Question juridique clé
Whether the complaint met the Federal Supreme Court's reasoning requirements
Solution extraite
No. The appellant did not engage with the decisive reasoning of the cantonal court, so the complaint was manifestly insufficiently reasoned.
Motifs extraits
Under Art. 42 BGG, the appellant had to explain concretely how the challenged judgment violated federal law; its submissions were mostly factual assertions and did not address the lower court's reasoning on service of the reminder and the lack of a qualified objection to the estimated assessment.
