Summary

Under Oklahoma's last injurious exposure rule, American Interstate Insurance Company, which insured the employer on that date, was responsible for the claim.

Questions Presented
- Whether competent evidence supported the Workers' Compensation Court's finding that Cauthon's last injurious exposure occurred on May 15, 1999.
- Whether Oklahoma's last injurious exposure rule requires an occupational-disease claimant to prove that the final exposure caused or contributed to the injury, rather than merely showing potentially causal or contributory conditions.
Holdings
- Competent evidence supported the Workers' Compensation Court's finding that Cauthon's last injurious exposure occurred on May 15, 1999.
- Under title 85, section 11(B)(4), an occupational-disease claimant may establish a presumptive date of last injurious exposure by showing potentially causal or contributory conditions at the employment. The employer or carrier may rebut that presumption, after which the claimant must show that the last exposure caused or contributed to the injury.
Key quotations
“The last injurious exposure rule relieves the employee of proving the allocation of liability among successive employers and their insurance carriers.” (¶ 12)
“This presumption does not shift the burden of proof from the claimant, but creates a rebuttable presumption which shifts the burden of producing evidence.” (¶ 14)
“COURT OF CIVIL APPEALS' OPINION VACATED; ORDER OF WORKERS' COMPENSATION COURT SUSTAINED.” (¶ 15)
Factual background
Gary Cauthon worked as a welder-fitter for Heat Transfer & Equipment from March 1991 through May 15, 1999, with alleged repeated exposure to fumes, dust, chemicals, and smoke that caused respiratory and related injuries. Connecticut Indemnity insured Heat Transfer from April 1, 1997, through March 31, 1999, and American Interstate insured it from April 1, 1999, through Cauthon's last day of employment. Medical evidence supported May 15, 1999, as the date of last injurious exposure, although the carriers disputed which insurer was liable.
Procedural history
The Workers' Compensation Court found that Gary Cauthon's last injurious exposure occurred on May 15, 1999, and assigned responsibility for benefits to American Interstate, the carrier on the risk at that time. A three-judge panel affirmed. The Court of Civil Appeals reversed and remanded, after which the Oklahoma Supreme Court granted certiorari, vacated the Court of Civil Appeals' opinion, and sustained the Workers' Compensation Court's order.
