Those amendments, set forth in
BACKGROUND
In order to place in context the issues presented
*448
in this case, it is necessary to review briefly the legislative history of the challenged statute. In 1980 and 1981, the Legislature enacted several amendments to the Workers’ Disability Compensation Act. As part of those amendments, the benefit rate structure was changed, providing for an increase in weekly compensation from two-thirds of an employee’s average weekly wages to eighty percent of an employee’s after-tax average weekly wages.
After § 354 became effective on March 31, 1982, some employers began to coordinate the workers’ compensation benefits of many of their retired or disabled employees, including some employees who had been injured prior to March 31, 1982. As a result, employees injured before that date were being subjected to a reduction of benefits through coordination, even though they did not receive the increased maximum benefit rates pursuant to the statutory amendment. In
Chambers v General Motors Corp,
1982 WCABO 132, the Workers’ Compensation Appeal Board held that the § 354 coordination-of-benefits provision could not be applied to claimants injured before March 31, 1982. Similarly, this Court, in

Nevertheless, the Supreme Court, in reviewing
Chambers, Franks,
and a third consolidated case, held that the Legislature in fact intended that the benefits of all disabled employees be coordinated after March 31, 1982, even if some of those employees were injured before that date.
Franks v White Pine Copper Div,
On December 30, 1985, the Supreme Court denied a motion to rehear the consolidated cases. However, the author of the
Franks
decision, Justice Patricia J. Boyle, dissented, voting to grant the motion for rehearing. Justice Boyle opined that reconsideration led her to believe — contrary
*450
to her earlier expressed view that the plain meaning of § 354 required the coordination of benefits for all disabled employees after March 31, 1982— that the language of § 354 "is ambiguous and requires construction,” and that "[t]he incorrect methodology of our opinion leaves serious questions regarding the original decision in these cases.”
There was significant public reaction criticizing the Supreme Court’s decision in
Franks.
Critics included members of the Legislature that had passed § 354; James M. Brakora, Director of the Bureau of Workers’ Disability Compensation; and former Governor William G. Milliken. In a letter dated October 25, 1985, Governor Milliken stated that the Supreme Court had misconstrued the intent of his administration and the Legislature because "[i]t was not our intent that the coordination apply in any way to persons who had suffered their injuries prior to the effective date of the amendments.” In response to the
Franks
opinion, the Legislature adopted
(17) The decision of the Michigan Supreme Court in Franks v White Pine Copper Division,422 Mich 636 (1985) is declared to have been erroneously rendered insofar as it interprets this section, it having been and being the legislative intention not to coordinate payments under this section resulting from liability pursuant to section 351, 361, or 835 for personal injuries occurring before March 31, 1982. It is the purpose of this amendatory act *451 to so affirm. This remedial and curative amendment shall be liberally construed to effectuate this purpose.
(18) This section applies to payments resulting from liability pursuant to section 351, 361 or 835 for personal injuries occurring on or after March 31, 1982. Any payments made to an employee resulting from liability pursuant to section 351, 361, or 835 for a personal injury occurring before March 31, 1982 that have not been coordinated under this section as of the effective date of this subsection shall not be coordinated, shall not be considered to have created an overpayment of compensation benefits, and shall not be subject to reimbursement to the employer or carrier.
(19) Notwithstanding any other section of this act, any payments made to an employee resulting from liability pursuant to section 351, 361, or 835 for a personal injury occurring before March 31, 1982 that have been coordinated before the effective date of this subsection shall be considered to be an underpayment of compensation benefits, and the amounts withheld pursuant to coordination shall be reimbursed with interest, within 60 days of the effective date of this subsection, to the employee by the employer or carrier.
(20) Notwithstanding any other section of this act, any employee who has paid an employer or carrier money alleged by the employer or carrier to be owed the employer or carrier because that employee’s benefits had not been coordinated under this section and whose date of personal injury was before March 31, 1982 shall be reimbursed with interest, within 60 days of the effective date of this subsection, that money by the employer or carrier. [MCL 418.354 (17)-(20); MSA 17.237(354) (17)-(20).]
FACTS AND PROCEDURAL HISTORY
In Docket No. 101298, plaintiff, Evert Romein, was receiving workers’ compensation benefits of *452 $99 per week due to injuries he sustained on December 5, 1977, while working for defendant, General Motors Corporation. In September, 1983, gmc began coordinating Romein’s workers’ compensation benefits based upon his receipt of pension and social security old-age benefits. As a result of this coordination, his benefits were reduced to zero dollars. In June, 1984, a hearing referee in the Bureau of Workers’ Disability Compensation ordered that Romein’s workers’ compensation benefits be paid without coordination and that gmc pay a $1,500 penalty. On May 20, 1987, the wcab, citing the Supreme Court’s decision in Franks, reversed the referee’s determination, prompting Romein to apply for leave to appeal in this Court.
In Docket No. 101510, plaintiff, Arturo Gonzalez, was receiving workers’ compensation benefits of $176 per week pursuant to a voluntary agreement of the parties due to a disabling lung condition Gonzalez allegedly had developed as a consequence of his exposure to certain materials while working for defendant, Ford Motor Company. In August, 1982, Ford began to coordinate Gonzalez’s benefits with other benefits he received, thus reducing his weekly workers’ compensation payment to zero dollars. In September, 1984, a hearing referee in the Bureau of Workers’ Disability Compensation found that Ford had improperly coordinated and reduced Gonzalez’s benefits, and ordered Ford to pay a $1,500 penalty. On May 27, 1987, the wcab, citing
In September, 1987, this Court granted leave to *453 appeal in both cases, consolidating them for accelerated consideration. 1
ISSUES
First, gmc and Ford argue that subsections 17 through 20 of § 354 violate the due process, US Const, Am XIV; Const 1963, art 1, § 17, and impairment of contract, US Const, art I, § 10; Const 1963, art 1, § 10, clauses of the United States and Michigan Constitutions by retroactively imposing an additional obligation upon employers, i.e., "by retroactively imposing additional liability upon employers for past compensation periods.” We disagree with this argument because the challenged retroactive legislation is justified by a rational legislative purpose,
Usery v Turner Elkhorn Mining Co,
The Workers’ Disability Compensation Act is remedial in nature and was enacted primarily to
*454
benefit the employees, not the employers, subject to its provisions.
Norwin v Ford Motor Co,
Moreover, in the
Franks
opinion itself, the Supreme Court stated that "[wjorkers’ compensation benefits are social-welfare income-maintenance benefits” and declared, citing
Lahti, supra,
pp 591-592, and
Shavers v Attorney General,
Second, gmc and Ford argue that subsections 17 through 20 of § 354 violate the separation of powers, Const 1963, art 3, § 2, and the one court of justice, Const 1963, art 6, § 1, clauses of the Michigan Constitution. The employers reason that, after the Supreme Court, in Franks, supra, declared what the law is under § 354 regarding an employer’s ability to coordinate the workers’ compensation benefits of employees such as those in the present cases, the Legislature, by passing subsec *456 tions 17 through 20 of § 354, in an attempt to change retroactively what the Court had declared, usurped a judicial function. In their brief on appeal, the employers in these cases place great emphasis on the assertion that it is "unprecedented in the law” for a Legislature to reverse and overrule a court decision by passing a statute with retroactive applicability.
We find the employers’ suggestion regarding the unprecedented nature of the challenged legislation to represent an indulgence in hyperbole. Such legislation may be included in that type of statutory enactment denominated as "curative.” Curative legislation has been defined as legislation enacted to cure defects in prior law. 2 Sands, Sutherland Statutory Construction (4th ed), § 41.11, p 410. See Note,
Congressional reversal of supreme court decisions: 1945-1957,
71 Harv L R 1324 (1958); Hochman,
The supreme court and the constitutionality of retroactive legislation,
73 Harv L R 692 (1960). As an example, we will cite a recent occurrence of such legislation in the federal forum. In 1981, the United States Supreme Court held that the term "wages” must be interpreted consistently for purposes of both income-tax withholding and the Federal Insurance Contributions Act (fica).
Rowan Companies, Inc v United States,
We find the employers’ argument on this issue to be meritless. The Legislature, in passing subsections 17 through 20 of § 354, did not attempt to direct the courts in the exercise of judicial power or to infringe on that power in any way; rather, it merely sought to cure a defect in a prior law erroneously interpreted by the Supreme Court. As noted in plaintiffs’ briefs on appeal, the Legislature’s amendatory language simply makes "explicit [the] . . . retrospective legislative purpose which the Supreme Court found in [Franks] to be wanting in the 1981 version of Section 354.” Under such a circumstance, we detect no violation of the separation of powers or the one court of justice clause of the Michigan Constitution._
*458 Since we uphold the validity of § 354(17)-(20) despite the constitutional challenges raised by the employers in these consolidated cases, we affirm the wcab’s decision in the appeal of Arturo Gonzalez and reverse the decision in the appeal of Evert Romein. However, in light of the confusion in the law regarding the issues presented in these cases, and the fact that a substantial question of statutory consruction was involved, we find that penalty benefits should not be assessed against the employers. MCL 418.801(2); MSA 17.237(801X2).
The decision in Romein is reversed and the decision in Gonzalez is affirmed as modified.
Notes
Subsequent to the date these consolidated cases were submitted to this Court for decision and oral argument was conducted, counsel for the parties unilaterally filed supplemental briefs, including a letter and exhibit by counsel for defendants, a reply by counsel for plaintiffs, and a response to plaintiffs’ reply by counsel for defendants. These documents were improperly filed, MCR 7.212(F), and shall not be considered by this Court in rendering its decision, MCR 7.212(H).
