OPINION
HARTZ, Judge.The Workers’ Compensation Division (the WCD) dismissed employer’s claim against the New Mexico Subsequent Injury Fund (the Fund) on the ground that employer had not filed a certificate of pre-existing impairment prior to worker’s subsequent injury, as required by a statute that became effective after the subsequent injury but before employer filed its claim against the Fund. Employer appeals. We reverse. FACTS
Because the Fund did not challenge the facts stated in employer’s docketing statement, we accept those facts as true for purposes of this appeal. See State v. Calanche, 91 N.M. 390, 574 P.2d 1018 (Ct.App.1978). Worker suffered an accidental work-related injury on July 21, 1987. Prior to that injury he had sustained an injury that caused a permanent physical impairment. Although employer had actual knowledge of the pre-existing physical impairment, at the time of worker’s subsequent injury it had not yet filed a certificate attesting to the pre-existing impairment. On September 23, 1987, worker filed a compensation claim against employer. Employer brought in the Fund as a party to the action on April 12, 1988.
Under the law in effect at the time of worker’s subsequent injury, employer could recover from the Fund even though prior to the injury it had not filed a certificate of pre-existing impairment, as long as employer had actual knowledge of worker’s pre-existing condition. See Fierro v. Stanley’s Hardware, 104 N.M. 50, 716 P.2d 241 (1986). In 1988, however, the legislature amended the Subsequent Injury Act to forbid an employer from recovering from the Fund for the subsequent injury unless a certificate had been filed before the subsequent injury. NMSA 1978, § 52-2-6(D) (Supp.1988) (Subsequent Injury Act is applicable only to disability arising out of accident taking place after certificate of pre-existing impairment has been filed). This amendment was effective March 8, 1988. 1988 N.M. Laws, ch. 109, § 4.
Acting on the Fund’s motion for summary judgment, the WCD decided that the amendment should apply in this case and dismissed employer’s claim against the Fund. Thus, employer’s claim was extinguished even though at the time of the subsequent injury it had no reason to know that it would be held to a prior-filing requirement.
DISCUSSION
Starting from the proposition that the filing requirement is a procedural matter, see City of Roswell v. Chavez, 108 N.M. 608, 775 P.2d 1325 (Ct.App.1989) (filing certificate is procedural prerequisite to recovery from the Fund), the Fund argues that the amendment to the filing requirement is a change in procedure, rather than substantive rights, and therefore should be applied retroactively. See Wilson v. New Mexico Lumber & Timber Co., 42 N.M. 438, 81 P.2d 61 (1938) (statutes dealing only with remedial procedure are generally given retroactive effect).
Nevertheless, in workers’ compensation cases the uniform rule in this state has been that a claim for benefits is governed by the law in effect at the time the cause of action accrued. See Noffsker v. K. Barnett & Sons, .72 N.M. 471, 384 P.2d 1022 (1963) (amount of medical expenses recoverable without court approval); Davis v. Meadors-Cherry Co., 65 N.M. 21, 331 P.2d 523 (1958) (worker’s right to an additional award because of aggravation of injury); Wilson v. New Mexico Lumber & Timber Co. (statute of limitations); Bateman v. Springer Bldg. Materials Corp., 108 N.M. 655, 777 P.2d 383 (Ct.App.1989) (worker’s right to attorney fees); Strickland v. Coca-Cola Bottling Co., 107 N.M. 500, 760 P.2d 793 (Ct.App.1988) (definition of disability). Amendments to the Workers’ Compensation Act have been applied only prospectively. Jaramillo v. Kaufman Plumbing & Heating Co., 103 N.M. 400, 708 P.2d 312 (1985) is not in point. The passage from that opinion quoted in the special concurrence related to whether a district court could determine that the worker had not been disabled in the past and then require the worker to repay prior disability benefits. The statute at issue had been enacted decades earlier, so there was no question as to “retroactive” application of the statute in the sense that we confront in this cage.
This uniformity in result follows from the sui generis nature of the Workers’ Compensation Act. See Bateman v. Springer Bldg. Materials Corp. As stated in Davis v. Meadors-Cherry Corp., 65 N.M. at 24, 331 P.2d at 525, “We are firmly committed to the doctrine that the remedy in a Workmen’s Compensation case is a part of the right[.]” For example, even though a statute of limitations is often considered a matter of remedial procedure and therefore applied retroactively, see, e.g., Standard Acc. Ins. Co. v. Miller, 170 F.2d 495 (7th Cir.1948), the New Mexico Supreme Court has held that the statute of limitations in our Workers’ Compensation Act is “a limitation upon the right as well as the remedy” and should not be applied retroactively. Wilson v. New Mexico Lumber & Timber Co., 42 N.M. at 442, 81 P.2d at 64. Therefore, we believe that it is not fruitful to analyze whether a provision of the Workers’ Compensation Act is a matter of remedial procedure in determining whether it should be applied retroactively. The teaching of our cases can be expressed in a simple rule upon which the legislature and litigants can rely: in the absence of express statutory language or compelling reasons to the contrary, any new provisions of the Workers’ Compensation Act shall apply only to causes of action accruing after the effective date of the provision.1
The same rule should apply to the Subsequent Injury Act. Employers’ claims for reimbursement under the Subsequent Injury Act, NMSA 1978, Sections 52-2-1 to 52-2-14 (Repl.Pamp.1987 and Supp.1988), are dependent on claims for benefits filed under the Workers’ Compensation Act. See § 52-2-5 (Supp.1988) (payments from subsequent injury fund may be made as reimbursement to employer for benefits paid under Workers’ Compensation Act). Because of the relationship between workers’ compensation claims and claims against the Fund, it is appropriate to apply equivalent rules of construction in interpreting the two acts. See Rader v. Don J. Cummings Co., 109 N.M. 219, 784 P.2d 88 (App.1989).
Turning to the dispute before us, the statute does not provide explicitly for retroactive application of the filing requirement. Nor is there any compelling reason to apply the requirement retroactively. On the contrary, we would find it offensive to impose a statutory requirement retroactively when the affected party, as in this case, would have had no reason to know of the requirement in time to comply with it, particularly when compliance would have been relatively easy. See 2 N. Singer, Sutherland Statutory Construction § 41-05 (Sands 4th ed.1986) (a decision regarding retroactivity properly rests on subtle judgments concerning fairness).
We reverse the grant of summary judgment and order the hearing officer to reinstate employer’s claim against the Fund.
IT IS SO ORDERED.
ALARID, J., concurs. DONNELLY, J., specially concurs.. We note that this rule is consistent with the result in Canton Textile Mills, Inc. v. Lathem, 253 Ga. 102, 317 S.E.2d 189 (1984), cited by the special concurrence, because the language of the statute was explicit.
