Where, as here, there is ample competent evidence supporting its findings they are binding on review. See Eisnach v. Industrial Commission, 633 P.2d 502 (Colo.App. 1981). IV.
Under ยง 8-43-201, C.R.S. (1995 Cum. Supp.), the claimant had the burden to prove he sustained a compensable injury. The question of whether the claimant carried the burden of proof is one of fact for resolution by the ALJ. Metro Moving and Storage Co. v. Gussert, 914 P.2d 411 (Colo.App. 1995); Eisnach v. Industrial Commission, 633 P.2d 502 (Colo.App. 1981). In determining whether the claimant carried his burden of proof, it was for the ALJ to assess the weight, credibility and inferences to be drawn from the evidence.
