Key legal question
Whether the disability pension decision had to be upheld on the existing medical record
Extracted holding
No. The record did not cover the relevant period sufficiently because the alleged somatic deterioration and hospital stay required further clarification.
Extracted reasoning
The insured had plausibly alleged a relevant worsening, including back pain and a two-week hospitalization before the objection decision. Under the investigative principle, the authorities had to obtain further medical reports instead of dismissing the allegation as unsubstantiated.
