Supreme Court allows appeal when a party raises valid objections to a written expert opinion requiring oral clarification.

The Supreme Court quashed the appellate court's decision to dismiss the claimant's request to summon a neurologist for oral examination. The lower court rejected the request because the expert's written opinion was deemed sufficiently reasoned, despite the claimant raising specific objections regarding the date of disability onset and internal contradictions. The Supreme Court ruled that the appellate court erred by failing to order oral clarification when the objections were not general but pointed to serious doubts in the expert's reasoning and conclusions.
