Questão jurídica principal
Whether the filing constituted an admissible appeal against a formal social insurance decision.
Decisão extraída
No. The filing did not include a formal challenged decision and was not clearly an appeal; after the cure period lapsed unused, it was deemed withdrawn.
Fundamentação extraída
Under the cantonal procedural rules, the challenged decision must accompany the appeal. Defective or unclear filings must be returned and corrected within a short deadline; if not corrected, they are deemed withdrawn. The appellant failed to submit any formal decision despite an express invitation.
