Questione giuridica chiave
Whether the denial of an IV pension was lawful despite the medical evidence on work capacity and medication dependence.
Decisione estratta
The existing evidence did not allow a final assessment of whether a relevant, possibly time-limited impairment in work and earning capacity had existed; further MEDAS clarification was required.
Motivazione estratta
The MEDAS report was largely reliable, but it was unclear from when its work-capacity assessment applied. The experts themselves acknowledged years of medication dependence after the 2003 rehabilitation stay, which could be iatrogenic and thus potentially invalidity-relevant. This ambiguity required a supplementary expert opinion.
