In this workers’ compensation case, the Commission adopted the administrative law judge’s opinion and found the appellant entitled to receive benefits. From that decision, comes this appeal.
On November 3,1982, while employed by Western Waterproofing in Oklahoma, the appellee suffered a compensable back injury. On January 17, 1983, Dr. Warren G. Low performed a lumbar laminectomy at L3/4, excising the disc and exploring the L5/S1. On April 4, 1983, Dr. Low released the appellee, assessing his permanent partial disability at 20% to the body as a whole. Dr. Low noted that there was no evidence of disc space infection or other abnormalities. Western Waterproofing paid the appellee $18,000.00 compensation for his permanent partial disability.
Shortly after he was released by Dr. Low, the appellee applied for a job with the appellant. On his job application, dated April 18, 1983, the appellee stated that he had no prior physical conditions which might limit his ability to work. The appellee and one of his witnesses, Freddy Scott, testified that the appellee told Raymond Roberts, president of the appellant corporation, about the prior back condition and that Roberts instructed the appellee not to include that information on his application, as it would increase the company’s insurance rates. Roberts testified that he did not tell the appellee to conceal his prior injury, and that he did not know of the prior injury until the appellee injured his back while working for the appellant.
The appellee began work for the appellant on either May 2, 1983, or May 3,1983, and, after working one full day, slipped and fell while attempting to move a 300 pound scaffold on wet ground, injuring his back. The appellee was treated for this injury by Dr. William Blankenship. Initially, Dr. Blankenship diagnosed the appellee’s injury as an acute strain to the lumbar spine. He further noted that the appellee, by history, had previously injured his back, with pain primarily in his right side and leg, but that he *243had been pain-free for the two months prior to the May, 1983, injury. Dr. Blankenship noted that the May, 1983, injury resulted in pain in the left side and leg (later spreading to both legs). On September 9, 1983, Dr. Blankenship stated in a letter that, after comparing the myelograms from the earlier injury, it was his opinion that the appellee was suffering from a continuation of his original injury.
The appellant initially accepted the claim as compensable, paying medical and temporary total disability benefits. Now the appellant fully controverts the claim. The Commission, without discussion, found that the May, 1983, injury was an aggravation of the preexisting injury or a new injury, thus rendering the appellant liable for the benefits. Furthermore, the Commission, finding the testimony of Scott and the appellee to be the more credible, held that the appellant was estopped from raising the defense of misrepresentation.
At the hearing before the Commission, the appellant requested permission to introduce as additional evidence a medical report prepared by a Dr. Metcalf on April 5,1983, and a copy of a joint petition settlement agreement between the appellee and Western Waterproofing. Both of these documents relate to the earlier injury. Dr. Metcalfs report rated the appellant’s permanent partial disability at 40.5% to the body as a whole (20.5% for physical limitation and 20% for pain). The joint petition agreement, dated April 21, 1983, states that the appellee was 27% disabled. The appellant, in seeking to have these documents introduced into evidence, stated that, despite its ongoing investigation, the documents had just been discovered. The Commission, noting that the administrative law judge had reserved the question of permanent disability for future determination, held the appellant had failed to show that the documents were relevant, were not cumulative, or were of a nature likely to change the result in the case. The Commission observed that the appellant was not precluded from offering the documents during further proceedings to determine permanent disability.
The appellant first contends that the Commission erred in holding that the appellant was estopped from raising the defense of misrepresentation on the employment application. Under the test set forth in Shippers Transport of Georgia v. *244 Stepp, 265 Ark. 365, 578 S.W.2d 232 (1979), the employer must show three things in order to successfully raise the defense of misrepresentation on an employment application:
(1) The employee must have knowingly and willfully made a false representation as to his physical condition. (2) The employer must have relied upon the false representation and this reliance must have been a substantial factor in the hiring. (3) There must have been a causal connection between the false representation and the injury.
265 Ark. at 369 (quoting 1 B A. Larson, Workmen’s Compensation Law, Section 47.53). All these factors must be present in order to claim the defense. Id. The appellee’s testimony, corroborated by that of Scott, was that the appellant knew of the prior injury and instructed the appellee not to include that information on his application. Questions of credibility and the weight to be given the evidence are exclusively within the province of the Commission. Morrow v. Mulberry Lumber Co., 5 Ark. App. 260, 635 S.W.2d 283 (1982). The reviewing court may not displace the Commission’s choice between two fairly conflicting views even though, if it were reviewing the matter de novo, the court might have made a different decision. De Francisco v. Arkansas Kraft Corporation, 5 Ark. App. 195, 636 S.W.2d 291 (1982). Here the Commission chose to believe the testimony of Scott and the appellee over that of Roberts. We cannot say that the Commission erred in so doing. We find that this evidence constitutes substantial evidence, supporting the Commission’s decision that the appellant was estopped from asserting the Shippers defense. The appellant could not have relied on the misrepresentation when it knew the true facts before the appellee was hired.
The appellant next contends that there is no substantial evidence to support the Commission’s finding that the May, 1983, injury was either a new injury or an aggravation, rather than a recurrence, of the prior injury. If the second injury is a recurrence of the first, the employer at the time of the first injury is liable. Moss v. El Dorado Drilling Co., 237 Ark. 80, 371 S.W.2d 528 (1963). If, however, an intervening cause, such as a second accidental injury, aggravates the original injury, then the employer at the time of the second injury is responsible for the *245consequences of that second injury. Bearden Lumber Co. v. Bond, 7 Ark. App. 65, 644 S.W.2d 321 (1983). “[I]n all our cases the test was and is the same: Is the second episode a natural and probable result of the first injury or was it precipitated by an independent intervening cause?” 7 Ark. App. at 72.
In the case at bar, Dr. Low’s report of April 4,1983, releasing the appellee for work, indicated that no disc space infections or other abnormalities existed. It is undisputed that the second injury occurred immediately after the appellee slipped while attempting to move a 300 pound scaffold on wet ground. Although Dr. Blankenship’s September 9,1983, letter states that the May, 1983, injury was a continuation and recurrence of the previous injury, his May 3, 1983, letter stated that the appellee had suffered an acute lumbar strain. As noted earlier in this opinion, the weight to be given these reports is the province of the Commission, not this Court. Morrow, supra. It is the Commission’s responsibility, as the fact finder, to reconcile any conflicts in the evidence. City of Magnolia v. Caswell, 269 Ark. 708, 600 S.W.2d 32 (Ark. App. 1980). There is substantial evidence which supports the Commission’s finding that the May, 1983, injury was either an aggravation of the earlier injury or a new injury. Therefore, even though the evidence might support the opposite result, we must affirm.
The appellant’s final point concerns the Commission’s right to remand a case to the administrative law judge for the taking of additional evidence under Ark. Stat. Ann. Section 81-1327 (c) (Supp. 1983). The appellant contends that the Commission abused its discretion in denying its motion for the submission of additional evidence. In Nicholas v. Hempstead County Memorial Hospital, 9 Ark. App. 261, 658 S.W.2d 408 (1983), we stated:
Clearly the Commission is vested with discretion in determining whether and under what circumstances a case appealed to them should be remanded for the taking of additional evidence. On appeal an exercise of that discretion will not be lightly disturbed.
9 Ark. App. at 267. (quoting Haygood v. Belcher, 5 Ark. App. 127, 633 S.W.2d 391 (1982).) A case should only be remanded if the newly discovered evidence is relevant, is not merely cumula*246tive, would change the result, and was diligently discovered and produced by the movant. Mason v. Lauck, 232 Ark. 891, 340 S.W.2d 575 (1960); Hill v. White-Rodgers, 10 Ark. App. 402, 665 S.W.2d 292 (1984); Haygood 5 Ark. App. at 133. The Commission found that the appellant failed to meet these criteria, and since we find no abuse of the Commission’s discretion, we affirm on this point.
The newly discovered evidence is non-cumulative only to the extent it establishes a different degree of permanent disability than that established by the evidence previously considered. The remainder of the evidence is cumulative, as it merely affirms Drs. Low and Blankenship’s records, indicating the location of the injury, the pain suffered by the appellee, and that the previous claim had been settled. In the case at bar, the degree of permanent disability apportionable between the employers is not an issue, since that question was specifically reserved for future proceedings. The Commission correctly noted that this evidence may be offered on the permanent disability question at a later date.
Affirmed.
