Questão jurídica principal
Whether the appeal sufficiently challenged the cantonal president's independent ground of late filing.
Decisão extraída
No. Because the appellant did not contest the principal ground that the recusal request was filed too late, the appeal was manifestly insufficient.
Fundamentação extraída
Where a decision rests on several independent and sufficient grounds, the appellant must show that each ground violates the law; failing to address one decisive ground renders the appeal inadmissible under simplified procedure.
