Whether the cantonal appeal against the non-entry decision was admissible despite being filed out of time without a restitution request.
No. The cantonal court rightly declared the appeal inadmissible because the time limit was not respected and no restitution of time was sought.
The appellant did not dispute that he missed the deadline, and he did not show before the cantonal court that he had sought restitution or explained when and how he learned of the remedy. The challenge was therefore barred for lack of exhausted cantonal remedies.
