Questão jurídica principal
Whether the insured person's new letters about possible extra lessons were admissible noven
Decisão extraída
The letters were inadmissible new evidence because the issue of hypothetical additional income had already been contested before the cantonal court and should have been produced earlier.
Fundamentação extraída
Under Art. 99(1) BGG, noven are admissible only if prompted by the cantonal judgment; here the insured had to adduce the evidence already in cantonal proceedings.
