Questão jurídica principal
Whether the cantonal court committed excessive formalism by declaring the appeal inadmissible for lack of ratification by the current lawyer.
Decisão extraída
Yes. The defect was readily curable, and the court should have invited A. to regularize the representation issue before declaring the appeal inadmissible.
Fundamentação extraída
The procedural situation was unclear, but the absence of ratification of the earlier lawyer's filing was an easily repairable defect. No overriding public interest justified an immediate inadmissibility ruling; the authority had to warn and give an opportunity to cure.
