McRoberts v. Gen. Elec. Co.
2013 Ohio 3083
Ohio Ct. App.2013Background
- McRoberts, GE machinist, sought workers’ compensation for left carpal tunnel syndrome and other conditions.
- Industrial Commission initially allowed several added conditions but disallowed three including left carpal tunnel syndrome.
- A magistrate held a bench trial; GE’s expert testified carpal tunnel syndrome was not more likely than not caused by GE but was a contributory factor.
- Trial court upheld the magistrate’s denial; McRoberts appeals under R.C. 4123.512.
- Court applies de novo standard for legal questions and manifest weight review for factual findings.
- Court ultimately holds McRoberts’ left carpal tunnel syndrome is not compensable as a pre-existing condition aggravated by employment.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Is left carpal tunnel syndrome an compensable occupational disease? | McRoberts contends work at GE caused the condition. | GE argues condition pre-existed and was aggravated, not caused by employment. | Not compensable; not proven proximate cause by employment. |
| Does dual causation render GE the proximate cause? | Work factors contributed to 30% of cause. | Dual causation does not satisfy proximity when pre-existing factors predominate. | Rejected; pre-existing disease aggravated by employment is not compensable unless aggravation itself is compensable. |
| Does aggravation of a pre-existing carpal tunnel by employment qualify as a compensable occupational disease? | Argues aggravation is a compensable occupational disease. | Brody controls; aggravation of pre-existing non-industrial condition is not compensable. | Not compensable; aggravation alone does not create a compensable injury. |
