Disability Benefits Claimant v. Administrative Authority: Sufficiency of Medical Evidence and Duty to Order Expert Examination

The appellant sought an assessment of their residual work capacity by a medical expert, but the lower authority denied this request, relying instead on existing medical documentation, which the appellant challenged as insufficient for a proper assessment of their claim for disability insurance benefits. The court reasoned that while the administrative body has discretion in ordering further expert examinations, this discretion is limited by the duty to adequately investigate the facts of the case, meaning that if the existing medical evidence is manifestly insufficient or contradictory regarding the claimant's capacity to work, the authority must order a new medical assessment to fulfill its obligation to establish the facts objectively.
