This case is before the court on petition for review of a decision of the court of appeals,
Racine Steel Castings v. Hardy,
This case arose from the slip-and-fall injury of petitioner, John R. Hardy (Hardy), suffered on July 15, 1981, during the course of his employment with Racine Steel. Hardy sought treatment for discomfort associated with his work injury from Jose Kanshepol-sky, M.D. (Dr. Kanshepolsky). Dr. Kanshepolsky performed a surgical procedure upon Hardy described as an "anterior cervical fusion,” which rendered him a quadriplegic. It is undisputed that Racine Steel has paid and will continue to pay worker’s compensation benefits to Hardy for his aggravated injury.
Hardy filed a submission of controversy with the patients compensation panel pursuant to ch. 655, Stats. (1983-84), alleging negligence on the part of Dr. Kanshepolsky, on March 7, 1983. On November 30, 1984, the panel found Dr. Kanshepolsky negligent in his treatment of Hardy. A settlement was then reached between Dr. Kanshepolsky and Hardy. During the pendency of the case before the patients compensation panel, on August 29,1983, Racine Steel filed a summons and complaint, seeking a declaratory judgment that sec. 102.29(3) is unconstitutional and that Racine Steel was entitled to subrogation against any proceeds of the medical malpractice claim. Subsequently, on February 26, 1986, the trial court found sec. 102.29(3) unconstitutional and held that Racine Steel was accordingly entitled to subrogation. Specifically, the trial court held:
*559 "[Section 102.29(3)] denies equal protection to all Wisconsin employers whose employees’ work-related injuries are aggravated by doctors, chiropractors or podiatrists. This limited classification, as analyzed above, makes no sense, is wholly arbitrary and frustrates the general purpose and sound public policy of third-party liability as set forth in 102.29(1) of the Workers’ Compensation Act. Because it is arbitrary and has no rational basis, it must 'rest on grounds wholly irrelevant to the achievement of the State’s objective,’ as set forth in McGowan v. Maryland, supra.”
Because the court found the equal protection argument dispositive, it did not resolve the due process issue.
The court of appeals affirmed the decision of the trial court, likewise finding no rational basis to support the statutory classification.
Racine Steel,
The question before us concerns the constitutionality of a statute, which is a question of law reviewable by this court without deference to the decisions of the courts below.
Guertin v. Harbour Assurance Co. of Bermuda, Ltd.,
Because neither party in the present case asserts the existence of a fundamental right or implication of a suspect class, this court will examine the challenged classification under sec. 102.29(3) for a rational basis. Under this rational basis analysis, "[e]qual protection of the law is denied only where the legislature has made irrational or arbitrary classification. ... The basic test is not whether some inequality results from the classification, but whether there exists any reasonable basis to justify the classification.”
Guertin,
*561 "[I]t is the court’s obligation to locate or to construct, if possible, a rationale that might have influenced the legislature and that reasonably upholds the legislative determination. The rationale which the court locates or constructs is not likely to be indisputable. But it is not our task to determine the wisdom of the rationale or the legislation. The legislature assays the data available and decides the course to follow.” Sambs,97 Wis. 2d at 371 .
Section 102.29 generally governs third-party liability to recipients of worker’s compensation. Third-party liability in malpractice actions is specifically addressed under 102.29(3):
"Nothing in this chapter shall prevent an employe from taking the compensation he or she may be entitled to under it and also maintaining a civil action against any physician, chiropractor or podiatrist for malpractice. The employer or compensation insurer shall have no interest in or right to share in the proceeds of any civil action against any physician, chiropractor or podiatrist for malpractice." 2 ( Emphasis added.)
That portion of sec. 102.29(3) which bars an employer from sharing in malpractice award proceeds is asserted to constitute an unconstitutional classification because such a sharing right exists generally as to all other third parties, including health care providers other than physicians, chiropractors, or podiatrists. Racine Steel has sought to demonstrate the alleged disparity by explaining that as a result of the opera *562 tion of the statute, two employers who are paying additional compensation for medical aggravation of a work-related injury are treated differently: one employer is barred from subrogation against a medical malpractice award because of the fortuity that its employee suffers an aggravation at the hands of a health care provider who is a physician, whereas a similarly situated employer whose employee’s injury is aggravated by a dentist is entitled to share in the proceeds of a malpractice action.
Our analysis of the propriety of the classification embodied in sec. 102.29(3) commences with our rejection of the analytical framework set forth by Racine Steel. Specifically, we fundamentally disagree with the argument of Racine Steel that sec. 102.29(3) creates impermissible classifications of
employers.
Section 102.29(3) applies equally to all employers. Fortuity may operate such that the statute’s provisions deny subrogation to employer A one day and permit subrogation to the same employer regarding the injury of a different employee the following day. In short, whether employer A or employer B is affected unfavorably by the provisions of sec. 102.29(3) is not due to a statutory classification of employers but is rather a function of circumstances equally likely to befall any employer. As observed by this court in
Treiber v. Knoll,
This court has previously addressed the question of standing to challenge the constitutionality of a statute: "In order to be able to raise [a] constitutional question ... , a party must have standing. A person does not have standing to challenge a statute on constitutional grounds upon a point not affecting his rights. Nor can one challenge the unequal protection afforded to members of a class unless he is a member of that class.”
Wirth,
*565
Additionally, we note that Racine Steel’s concession that sec. 102.29(3) would be cured of the alleged disparities if subrogation were denied to
all
health care providers does not threaten Racine Steel’s standing. Certainly, if the only remedy which would be available to respond to the purported equal protection violation would be the expansion of the class as to which employers were denied subrogation, Racine Steel would not be "harmed” without such "relief’ and would, therefore, not have standing to challenge the statute. However, "when the 'right invoked is that of equal treatment,’ the appropriate remedy is a
mandate
of equal treatment, a result that can be accomplished by withdrawal of benefits from the favored class as well as by extension of benefits to the excluded class.”
Heckler v. Mathews,
Having found that Racine Steel has standing to challenge sec. 102.29(3), we proceed to consider the merits of the equal protection challenge. We must determine whether Racine Steel has established beyond a reasonable doubt that there exists no rational basis for classification presented under sec. 102.29(3).
Underlying our analysis of the constitutionality of sec. 102.29(3) is a familiar principle: this court is firmly committed to avoiding disruption of the all-pervasive legislative scheme which balances the corn-
*566
peting interests of employer against employee.
Mulder v. Acme-Cleveland Corp.,
The bar to employer subrogation against malpractice proceeds was introduced into the worker’s compensation scheme in 1949. Chapter 107, sec. 7, laws of 1949. As first enacted, however, only physicians and surgeons were included within the subrogation proscription. The drafting records contain no revelation of the purpose sought to be accomplished by the limited *567 subrogation bar. The court of appeals, however, opined that an examination of the legislative history of the statute suggests that a rational basis for the statute may once have existed.
Specifically, the court of appeals and Hardy, on appeal, outline the fact that at the time the subrogation bar was enacted in 1949, employers were entitled to name a panel of physicians from which the employee was to choose. Sec. 102.42(2), Stats. (1949). Because the employer limited the employee’s choice of physicians to those it had itself chosen, the rational basis addressed by the court of appeals presumably existed in the fact that the employee should not suffer by foregoing full economic remuneration from awards resulting from the malpractice of a physician selected by the employer. In 1975, both sec. 102.29(3) and sec. 102.42(2) were amended to include within the subrogation bar physicians, chiropractors, and podiatrists. Chapter 147, secs. 24, 28, laws of 1975. This articulated rational basis under which the burden of the malpractice of physicians, chiropractors, and podiatrists was deemed justifiably placed upon employers who had themselves chosen a panel of practitioners was present within ch. 102 until 1977 when the employer’s right to name these health care providers under sec. 102.42(2) was removed. Chapter 195, sec. 24, laws of 1977. While it is true that the relationship between sec. 102.42(2) and sec. 102.29(3) may have constituted a rational basis for the classification of physicians, chiropractors, and podiatrists under sec. 102.29(3), merely because this relationship has been terminated, it does not follow that an equally forceful rational basis does not elsewhere exist.
The court of appeals held, and Hardy would appear to concede, that there does exist a rational
*568
basis which would support a distinction in subrogation rights between third parties generally and all health care providers.
See Racine Steel,
*569 Professor Tribe, commenting upon underinclusi-veness, has observed:
"Parallel to its concern that the political process be allowed primacy in defining the ends to be served, the Court has recognized the legislative need for approximation in choosing the means of serving them.
"'Underinclusiveness’ is one such variant of approximation which the Court may invalidate as too arbitrarily departing from 'mathematical nicety.’ Underinclusive classifications do not include all who are similarly situated with respect to a rule, and thereby burden less than would be logical to achieve the intended government end. In defense of underinclusiveness it has been argued that piecemeal legislation is a pragmatic means of effecting needed reforms, where a demand for completeness may lead to total paralysis_” L. Tribe, supra p. 8, §16-4 at 1446-47 (footnotes omitted).
The United States Supreme Court has consistently accorded some tolerance to the failure of legislative classifications to address problems with absolute precision.
The problem of legislative classification is a perennial one, admitting of no doctrinaire definition. Evils in the same field may be of different dimensions and proportions, requiring different remedies. Or so the legislature may think. Tigner v. Texas,310 U.S. 141 [(1940)]. Or the reform may take one step at a time, addressing itself to the phase of the problem which seems most acute to the legislative mind. Semler v. Dental Examiners,294 U.S. 608 [1935)]. The legislature may select one *570 phase of one field and apply a remedy there, neglecting the others. A. F. of L. v. American Sash Co.,335 U.S. 538 [(1949]. Williamson v. Lee Optical Co.,348 U.S. 483 , 489, reh’g denied349 U.S. 925 (1955).
In seeking to preserve, to the greatest extent possible, the judgment of the legislature, this court has similarly recognized that if "the law presumably hits the evil where it is most felt, it is not to be overthrown because there are other instances to which it might have been applied.”
State v. Hart,
In
Omernik,
"[I]t is not required that all ills or ailments be cured or their cure attempted in a single piece of legislation.... We hold the legislative classification here to have a reasonable basis, repeating that, within the limits of what is reasonable,'... it is for the legislature and not for the court to determine the exact point at which a classification is to operate.’” Id. (quoting State ex rel. Harvey v. Morgan,30 Wis. 2d 1 , 9,139 N.W.2d 585 (1966)).

Finally, the United States Supreme Court very recently stated with respect to an equal protection claim: "It of course is possible that Mississippi might have enacted a statute that more precisely serves these goals and these goals only; as we frequently have explained, however, a state statute need not be so perfectly calibrated in order to pass muster under the rational basis test.”
Bankers Life and Casualty Co. v. Crenshaw,
Moreover, were it necessary for this court to find a rational basis to support not only the classification distinguishing physicians, chiropractors, and podiatrists from third parties generally, but also to locate, a rationale for the omission of additional health care *573 providers within the subrogation bar of sec. 102.29(3), such a rational basis for this "subclassification” could be found. Specifically, we observe that elsewhere within the ch. 102 worker’s compensation scheme provisions regarding health care refer exclusively to physicians, chiropractors, and podiatrists. The following sections demonstrate a scheme throughout ch. 102 indicating a legislative determination that physicians, chiropractors,' and podiatrists are generally the best equipped to assess disability and to treat work-related injuries: Section 102.13, Stats, (employer’s right to require examination of employee by physician, chiropractor, or podiatrist); sec. 102.17(l)(e) and (g) (department of industry, labor and human relations right to direct an employee to be examined by physician, chiropractor, or podiatrist); sec. 102.42(2) (requirement that employer offer to employee choice of any physician, chiropractor, or podiatrist practicing in this state). Significantly, chiropractors and podiatrists were included within sec. 102.29 as well as within each of these provisions as a result of the same legislation adopted under ch. 147, laws of 1975. We note that Racine Steel has directed the court’s attention to several sections in ch. 102 which include provisions regarding additional health care providers. 3 However, these tangential references to addition *574 al health care services and providers do not detract from the fundamental scheme highlighting physicians, chiropractors, and podiatrists as the health care providers fundamental to the assessment and treatment of work-related injuries or consequential disability. None of the statutory sections cited by Racine Steel creates obligations on the part of the employee to submit to examination by an additional health care provider nor do these sections specifically identify any additional medical practitioners whose services must be provided by the employer to the employee. As such, these provisions are not as fundamentally related to the assessment and treatment of work-related injuries as are those which do exclusively pertain to physicians, chiropractors, and podiatrists.
This scheme, embodied within ch. 102, setting apart physicians, chiropractors, and podiatrists from other health care providers, does have a rational basis: the health care providers specified in sec. 102.29(3) typically perform more invasive and potentially injurious procedures. This rational basis justifies the subclassification which, while imperfect, sets apart these practitioners with respect to the fact that they are generally the best equipped regarding the assess *575 ment of disability, treatment of work-related injury, and concomitant greater likelihood of injury in the event of malpractice.
It may indeed have been the intent of the legislature in structuring the subclassification of health care providers to permit the employee to retain the entirety of a malpractice award where the injury resulting from the aggravation was more likely to be severe in order to compensate for the fact that the employer was responsible for the original injury and the employee would not be fully compensated with worker’s compensation benefits. Accordingly, even if it were necessary to examine sec. 102.29(3) not only for a rational basis for the primary classification, but also to find a rational basis for the subclassification created by the purportedly underinclusive classification, there is ample justification to support the inclusion of physicians, chiropractors, and podiatrists and exclusion of other health care providers under sec. 102.29(3). For all the above reasons, we find sec. 102.29(3), Stats., to be constitutional.
By the Court. — The decision of the court of appeals is reversed.
Notes
Before the trial court, Racine Steel articulated an alternative constitutional infirmity, asserting that sec. 102.29(3) unconstitutionally deprived employers of due process by assertedly arbitrarily denying employers subrogation. The trial court did not address this issue because the equal protection arguments were found dispositive. The court of appeals likewise did not address the due process argument. Because this issue was neither briefed nor argued before the court in oral argument, we do not address this issue.
See, e.g., Estate of Atkinson: Atkinson v. Department of Taxation,
That portion of sec. 102.29(3) barring subrogation against proceeds awarded in a malpractice action against a physician, chiropractor, or podiatrist (emphasized above) has recently been repealed by 1987 Wis. act 179, sec. 13 (effective date April 1,1988).
Those provisions set forth by Racine Steel include the following: sec. 102.13(2) (requirement that treating "physician, chiropractor, podiatrist, hospital or health care provider” provide information relating to work-related injury); sec 102.16(3) (bars employer solicitation or requirement that employee or other person purchase "medical, chiropractic, podiatric or hospital tickets or contracts” for medical, surgical, hospital or other health care treatment); sec. 102.42(1) (employer required to provide medical, surgical, chiropractic, podiatric and hospital treatment, *574 medicines and supplies). Additionally, Racine Steel refers to sec. 102.17(l)(d). Section 102.17(l)(d), Stats. (1981-82), refers to the admission of the contents of verified medical and surgical reports prepared by physicians, podiatrists, surgeons, chiropractors, and dentists. The current statute, in effect at the date of Hardy’s injury, additionally includes psychologists within sec. 102.17(l)(d), Stats. (1985-86). With respect to this statute, it should be first noted that surgeons are physicians such that the reference to surgeons is not to an additional health care provider. Second, it is important to recognize that the reports of doctors of dentistry are admissible regarding diagnosis but not disability.
