Narrative Opinion Summary
This case involves a teacher employed by the San Juan Unified School District who sustained a cumulative psychiatric injury during his employment, leading to a dispute over the apportionment of his disability. The primary legal issue centers on whether the apportionment of 50% of his psychiatric disability to nonindustrial causes was appropriate under California Labor Code sections 4663 and 4750. Dr. Groesbeck initially attributed the disability entirely to industrial causes but later revised his opinion, citing nonindustrial factors such as preexisting personality issues and spousal depression. The Workers' Compensation Appeals Board upheld this apportionment, but the court found it erroneous, emphasizing the lack of substantial evidence for independent contribution by preexisting conditions. The court annulled the apportionment award and remanded the matter for further proceedings, underscoring the necessity for medical testimony to demonstrate a natural progression of preexisting conditions. The ruling highlights concerns about using speculative medical opinions and prophylactic work restrictions in apportionment cases, affirming that employers should only be liable for disabilities directly attributable to new industrial injuries.

Application: The court evaluated the apportionment of disability, emphasizing that it must be based on substantial evidence that a preexisting condition contributed to the disability independently of the industrial injury.
Reasoning: The board's apportionment of disability was based on a preexisting psychiatric condition, but it did not demonstrate the natural progression of this condition.

Application: The court noted the significant impact of job loss on Ditler's mental health, although it found that nonindustrial factors like his wife's depression played a role.
Reasoning: Dr. Groesbeck highlighted the impact of job loss on the individual's mental health, emphasizing the interplay between his job, his wife’s depression, and long-standing personality issues.
Limitations of Prophylactic Work Restrictionssubscribe to see similar legal issues
Application: The court rejected the use of prophylactic work restrictions to imply a prior disability, emphasizing the need for concrete evidence of preexisting conditions.
Reasoning: A prophylactic work restriction cannot be applied retrospectively to imply a prior disability that did not exist, as established in Gross v. Workmen's Comp. Appeals Bd.
Medical Evidence Requirement for Apportionmentsubscribe to see similar legal issues
Application: Dr. Groesbeck's testimony was deemed insufficient for apportionment as it failed to demonstrate that Ditler's preexisting condition was labor disabling and primarily attributed the disability to industrial factors.
Reasoning: Dr. Groesbeck's report and testimony are inadequate for supporting an apportionment finding because his opinion attributed Ditler's psychiatric disability primarily to work conditions.
