Whether the appeal satisfied the reasoning requirements of Art. 42 LTF.
Decisione estratta
The appeal did not sufficiently address the only issue decided below and failed to explain why the cantonal findings were incorrect or the judgment unlawful.
Motivazione estratta
The submission contained no argument on the set-off between ongoing invalidity benefits and contributions due for 2001/2002, so it did not meet the minimum requirements of a reasoned appeal under Art. 42 paras. 1 and 2 LTF.
