Vanda v. Minnesota Mining & Manufacturing Co.Vanda v. Minnesota Mining & Manufacturing Co.
Writ of certiorari to review a decision of the Workmen’s Compensation Commission granting employee compensation for a 30-percent per
*516
manent partial disability of the back. Employer does not contend that employee’s disability is less than 30 percent nor does it deny liability for at least part of this 30 percent. What employer contends is that in view of the expert testimony on the issue of causation, the commission should have held it liable for only a part of the disability. We reject this contention. The longstanding rule, applied by this court in numerous cases, is that when the usual tasks ordinary to an employee’s work substantially aggravate, accelerate, or combine with a preexisting disease or latent condition to produce a disability, the entire disability is compensable, no apportionment being made on the basis of relative causal contribution of the preexisting condition and the work activities. Forseen v. Tire Retread Co. Inc.
Affirmed.
