Supreme Court quashes social security award denial due to failure to order expert witness oral testimony.

The Supreme Court quashed the Social Security Institution's refusal of a death benefit, ruling that the lower court failed to order oral testimony from a work medicine expert. The deceased employee died at his workplace after arriving late and refusing a substitute, yet the lower court relied solely on a written expert opinion without addressing the applicant's objections. The court held that ignoring valid objections to an expert's written report constitutes a procedural violation under the Code of Civil Procedure, necessitating a retrial to establish the factual basis for the accident classification.
