Key legal question
Whether the claimant's possible juvenile disability under Art. 26 IVV had to be medically clarified before assessing the pension claim
Extracted holding
The file did not allow a reliable finding that she had freely renounced vocational training; further medical clarification was required on whether invalidity prevented her from acquiring adequate vocational skills.
Extracted reasoning
The psychiatric expert linked the lack of vocational training to a personality disorder, and no other medical opinions addressed this point. By relying on the remaining file without clarifying the medical issue, the cantonal court violated the duty to investigate under Art. 61 lit. c ATSG.
