Questão jurídica principal
Whether the appeal was validly filed through a representative without a specific power of attorney for court proceedings.
Decisão extraída
No. A management mandate was insufficient for litigation representation, and the invited power of attorney was not produced; the insured did not personally appeal.
Fundamentação extraída
Under the applicable cantonal procedural rules, representation in court requires an express power of attorney. After warning, the purported representative failed to demonstrate authority to act in justice, so the appeal could not be examined on the merits.
