No. The filing did not explain why the lower court's finding about the untimely payment of the cost advance and the resulting non-entry decision was wrong.
Motifs extraits
Under Art. 42(1) and (2) BGG, the appeal must contain requests and reasons showing in a concise manner how the challenged decision violates law. That threshold was not met.
