Appeal from workmen’s compensation appeal board. Plaintiff Kido claims injury in March of 1952, occurring during the course of employment. He alleges that at that time he fell on a slippery floor at defendant’s plant and suffered back injuries which have been continuing and for which he seeks compensation. The hearing referee found that such an accident had occurred and awarded compensation. The workmen’s compensation appeal board reversed the award and entered an order denying compensation. It is from this order plaintiff appeals.

Plaintiff’s contention is that the appeal board in considering the evidence overlooked important testimony. We are unable to accept this argument. The testimony which plaintiff claims was ignored was his *433own. It had to do with the alleged accident and whether or not this accident had been reported to defendant. The appeal board found that there had been no such accident. It was entitled and indeed was obliged to weigh and accept or reject plaintiff’s testimony regarding the occurrence. Plaintiff’s testimony as to reporting the alleged accident was unrebutted but also unsupported. The fact that the board rejected the testimony does not constitute any irregularity in the review process as conducted by the board but, indeed, is inherent in the nature of the process.

The workmen’s compensation appeal board* is trier of the facts in compensation cases and makes its own determination as to the credibility of witnesses and the weight to be given their testimony. Spada v. Ford Motor Company (1934), 269 Mich 354; Gotich v. Kalamazoo Stove Company (1958), 352 Mich 88; Hollingsworth v. Auto Specialties Manufacturing Company (1958), 352 Mich 255; Coates v. Continental Motors Corporation (1964), 373 Mich 461.

The appeal board found as a matter of fact that there had been no accident. In doing so, it rejected plaintiff’s testimony that there had been an accident and that the accident had been reported.

The findings of fact made by the workmen’s compensation appeal board, in absence of fraud, were conclusive. CL 1948, § 413.12 (Stat Ann 1960 Rev § 17.186).

Judgment affirmed.
