Kernrechtsfrage
Whether the cantonal judgment and the IV decision had to be set aside for further medical investigation, including psychiatric examination in Turkish and a new somatic assessment.
Extrahierter Entscheid
No further evidentiary measures were required; the existing medical reports were sufficiently reliable and showed no relevant worsening.
Extrahierte Begründung
The psychiatric report showed no translation problems affecting findings; the claimant had long lived in German-speaking regions and did not timely request an interpreter. Tinnitus was documented but not shown to affect work capacity, and the later pneumonia report did not establish a sustained deterioration before the objection decision.
