Kernrechtsfrage
Whether the cantonal court could enter into the insured person's appeal despite a lack of legal interest
Extrahierter Entscheid
The cantonal court should not have entered the appeal because the insured person was not adversely affected in a legally relevant way and lacked a current legal interest.
Extrahierte Begründung
Due to Art. 43(1) IVG and the widow's pension situation, the reduction in the IV degree did not change the actual pension amount; any possible future interest, including potential supplementary benefits, was too remote.
