Questione giuridica chiave
Whether the appeal against the inadmissibility judgment met the federal motivation requirements
Decisione estratta
The appeal was not properly reasoned against the inadmissibility ruling and was rejected insofar as it was admissible.
Motivazione estratta
Under Art. 42 paras. 1-2 LTF, a remedy must explain briefly why the challenged decision is unlawful. The filing mainly addressed the merits of the disability-insurance dispute and did not engage with the specific ground of inadmissibility. The late request to extend the deadline for the advance on costs could not cure the lack of timely payment.
