Supreme Court quashes social security appeal for failure to examine pre-accident health status regarding disability onset date.

The Supreme Court quashed the appellate court's decision denying a disability pension to the applicant. The applicant argued the lower court failed to properly evaluate his pre-accident health status when determining the date of disability onset. The court ruled that the appellate court arbitrarily fixed the disability date without considering whether pre-existing conditions justified recognizing the applicant as disabled before the accident.
