Questão jurídica principal
Whether the cantonal appeal against the IV decision of 31 January 2013 was filed in time.
Decisão extraída
The appeal period started with defective service to the representative organization on 6 February 2013, so the 8 March 2013 appeal was timely.
Fundamentação extraída
The IV office had treated the Lung League as the insured person's representative over time and should have served the denial decision on it. Because defective service may not prejudice the party, the copy sent to the Lung League triggered the 30-day appeal period.
