Kernrechtsfrage
Whether the IV office violated the right to be heard by not forwarding the C.___ supplemental opinion before the refusal decision
Extrahierter Entscheid
The right to be heard was violated, but only lightly and the defect was curable on appeal because the supplemental opinion added no new medical findings.
Extrahierte Begründung
The supplemental opinion was part of the decision basis and should have been disclosed, yet it merely confirmed the prior assessment and was not decision-determinative.
