Key legal question
Whether the medical file sufficiently established a relevant worsening of the insured person's condition
Extracted holding
The file did not show a sufficiently probable relevant physical worsening; further medical investigations were unnecessary.
Extracted reasoning
The treating doctor asserted deterioration, but the specialist reports and orthopedic findings showed only slight changes and no adequate somatic correlate. The new psychological findings were linked mainly to psychosocial stressors and did not amount to a disabling mental illness.
