Claimant contends that the deputy commissioner erred in dismissing his claim. We affirm.

*833The dismissal is authorized by Martin Co. v. Carpenter, 132 So.2d 400 (Fla. 1961). There is competent substantial evidence in the record that (1) claimant knowingly made false representations, (2) the employer relied on the misrepresentations, and (3) there was a causal connection between the misrepresentations and the injury.
