Question juridique clé
Whether the federal appeal met the reasoning requirement of Art. 42 BGG against a non-entry decision.
Solution extraite
No. The appellants did not engage with the cantonal court's timeliness reasoning in a substantive way; their brief was therefore insufficiently reasoned.
Motifs extraits
An appeal against a non-entry decision must address the grounds that justified non-entry. The single remark that 22 June 2011 was a Saturday was plainly incorrect and did not confront the decisive timeliness calculation.
