On February 18, 1969, while in the course of her employment with the defendant, plaintiff fell on a concrete floor after slipping in a pool of oil. On June 9, 1970, the parties to this action entered into an "Agreement to Redeem Liability” under which, in exchange for $10,500, *65plaintiff waived any right to medical benefits and weekly payments under the Workmen’s Compensation Act arising from the accident. A hearing was held before a workmen’s compensation referee on June 15, 1970, and a redemption order was entered.
On November 1, 1971, plaintiff filed a claim for benefits in the workmen’s compensation bureau seeking benefits for the February 18, 1969, accident. The referee dismissed the claim with prejudice, finding that defendant’s liability had been redeemed. The appeal board affirmed.
On August 31, 1973, plaintiff filed this action to set aside the redemption order. Plaintiff alleged that the February 18, 1969, fall resulted in severe pain in the back, shoulders and buttocks. She was examined by several doctors at defendant’s direction. All the doctors diagnosed plaintiff’s medical problems as minimal, so plaintiff attempted to return to work but found the pain unbearable. Plaintiff was again examined and her symptoms were said to be due to either a sprain, bursitis or a psychosis. Believing that she had no real physical illness, plaintiff settled with defendant for $10,500. After she signed the redemption agreement plaintiff discovered that she had a herniated disc and a fractured coccyx. Plaintiff’s pain was not "in her head” but in fact was caused by bone spurs compressing nerve roots in the spine.
Plaintiff alleged that there was a mutual mistake regarding the nature of her injuries due to the erroneous diagnoses of the physicians to which she was sent. Plaintiff thus sought to have the redemption agreement nullified as being unfair and based upon a good faith mistake on the part of both parties.
Defendant moved for and was granted summary *66judgment. The trial court ruled that a redemption order issued by the workmen’s compensation bureau is a final determination that cannot be vacated by a court exercising equity jurisdiction unless the order is shown to have been fraudulently procured. Plaintiff appeals.
In granting summary judgment for the defendant, the trial court relied upon the rule set out in Johnston’s Administrator v United Airlines, 23 Mich App 279, 285; 178 NW2d 536 (1970):
"A redemption order is a final determination and an award made and accepted cannot be disturbed except upon a showing that it was procured by fraud. Panozzo v Ford Motor Co. (1931), 255 Mich 149 [237 NW 369]; Catina v Hudson Motor Car Co. (1935), 272 Mich 377 [262 NW 266].”
We find that this rule describes too narrowly the available judicial relief from a final redemption order.
An approved redemption agreement, unlike an approved lump sum settlement agreement, is not subject to reopening by the workmen’s compensation bureau upon a showing of change in the claimant’s physical condition. Norbut v I Stephenson Co, 217 Mich 345, 347; 186 NW 716 (1922). Relief from a redemption agreement is available, however, in equity. Panozzo v Ford Motor Co, 255 Mich 149; 237 NW 369 (1931). In Panozzo the claimant sought to have a compensation settlement order set aside, claiming that it was procured by fraud. The Court followed the rule that a court of equity may grant such relief from a final settlement receipt which was procured by fraud. The Court did not say that such relief was available only when fraud is shown. Nor do the cases *67cited in Panozzo limit relief from settlement or redemption orders to actions in which fraud was alleged and proven. In Smith v Port Huron Gas & Electric Co, 217 Mich 519; 187 NW 292 (1922), and American Life Insurance Co v Balmer, 238 Mich 580; 214 NW 208 (1927), the Court compared workmen’s compensation awards to awards of arbitrators, stating that they were res judicata and could be attacked only in equity where the applicable claim of fraud, accident or mistake could be made. See Palmer v Patron’s Mutual Fire Insurance Co of Michigan, 217 Mich 292; 186 NW 511 (1922). In cases decided since Panozzo the Supreme Court has recognized the possibility of impeaching in a court of equity a compensation agreement entered into by mistake. Righi v Robert Gage Coal Co, 269 Mich 46; 256 NW 617 (1934), Hughson v Kalamazoo, 271 Mich 36; 260 NW 111 (1935), Baughman v Grand Trunk W R Co, 277 Mich 70; 268 NW 815 (1936).1 In Avery v Eddy Paper Corp, 295 Mich 277; 294 NW 679 (1940), for example, the Supreme Court affirmed a circuit court order setting aside a final settlement receipt where a doctor made misstatements (not necessarily fraudulent) to the claimant concerning the extent of his injury.
It has been recognized in other jurisdictions that relief from a compensation settlement is available where shown to have been procured by or based upon a mutual mistake of a material fact. Maryland Casualty Co v McWilliams, 175 F2d 475 (CA 5, 1949), Hansen’s Case, 350 Mass 178; 213 NE2d 869 (1966), Morgan v Duncan, 361 Mo 683; 236 SW2d 281 (1951), Herrera v C & R Paving Co, 73 *68NM 237; 387 P2d 339 (1963), Clark v Gastonia Ice Cream Co, 261 NC 234; 134 SE2d 354 (1964).2
Little justification can be found for limiting the power of a court to set aside a redemption order to cases of fraud. The injustice such a rule can permit, on the other hand, is demonstrated in the case at bar. Although the plaintiff has alleged that the redemption agreement was based on completely erroneous diagnoses and that she is suffering from a much more serious disability then previously believed, she has had no opportunity to prove her allegations in any manner. To require proof of fraud in the procurement of the redemption agreement before any relief will be granted is improper. The argument is well-stated in 3 Larson, Workmen’s Compensation Law, § 81.52:
"In view of the practical protective function of workmen’s compensation, the desirability of preserving a right to reopen for genuine mistake seems too self-evident for argument. In the nature of things, there are bound to be many occasions when even the most thorough and skillful diagnosis misses some hidden compensable condition. Should the claimant then be penalized because of an erroneous disposition, either by award or settlement, when the only fault lies in the imperfections of medical science?”
We hold that a court exercising equity jurisdiction may set aside a workmen’s compensation redemption order where the claimant has a meritorious claim for greater compensation than he has received and where in entering into the redemption agreement the claimant relied upon false representations (even though made in good faith) concerning his medical condition made by *69the employer’s doctor. See 0Alvarez v Employer’s Fire Insurance Co, 531 SW2d 218 (Tex Civ App, 1976).
The order of the trial court granting summary judgment for the defendant is reversed. This cause is remanded to the trial court for further proceedings.
D. F. Walsh, J., concurred.Compare, Denton v Utley, 350 Mich 332; 86 NW2d 537 (1957): mistake on part of plaintiff as to extent of his injuries may justify setting aside release of tortfeasor. See Hall v Strom Construction Co, 368 Mich 253; 118 NW2d 281 (1962).
But see, Lambert v Remington Rand, Inc, 334 Ill App 176; 78 NE2d 852 (1948), Griffin v Coal Operators Casualty Co, 84 So 2d 481 (La App, 1955).
