What is the effect of the California Workmen's Compensation Act on a claimant who is successful in his claim?

'We are of the view that the statute provides that a claimant, whether successful or not, is entitled to be reimbursed for expenses reasonably and necessarily incurred for the specified medical services. This construction is in accord with the policy of the law enjoined by both statute and precedent directing that workmen's compensation laws be liberally [237 Cal.App.2d 459] construed in favor of extending their benefits. (Subsequent Injuries Fund v. Industrial Acc. Com., 39 Cal.2d 83, 91, 244 P.2d 889.)'
