Plaintiff appeals as of right from the trial court’s order summarily dismissing defendant Harold Sauer, M.D., from this medical malpractice action on the basis of the governmental immunity privilege set forth in MCL 691.1407(2); MSA 3.996(107)(2). We affirm.
Sauer is an obstetrician, gynecologist, and teacher employed by the Michigan State University College of Human Medicine as an associate professor in the Department of Obstetrics, Gynecology, and Reproductive Biology. In this capacity, Sauer is compensated entirely by msu, he teaches medical students and residents, he provides clini*392cal care at the MSU Clinical Center, and he provides inpatient medical care at St. Lawrence Hospital in conjunction with the Msu/St. Lawrence Hospital Family Practice Residency Program. In July 1990, plaintiffs decedent, Janet Vargo, then pregnant, went to St. Lawrence Hospital complaining of shortness of breath and a pain in her chest. That evening, after physicians and residents examined Vargo, defendant Dr. James Rawlinson consulted with defendant Sauer, who determined that the fetus was in distress and recommended an emergency Caesarean section delivery. The delivery was successful and Vargo gave birth to a healthy boy; soon thereafter, however, Janet Vargo suffered heart failure, lapsed into a coma, and died.
Sauer filed his motion for summary disposition pursuant to MCR 2.116(C)(7) and (8). According to Sauer, he participated in Janet Vargo’s care as part of his employment with msu and his responsibility to teach msu residents, so he is immune from tort liability except with respect to gross negligence. MCL 691.1407; MSA 3.996(107). Also, Sauer asserted that plaintiffs allegations of gross negligence failed to establish conduct so reckless as to show a substantial lack of concern for whether an injury resulted, MCL 691.1407(2)(c); MSA 3.996(107)(2)(c), and, therefore, plaintiff failed to state a claim upon which relief could be granted. The trial court reluctantly granted Sauer’s motion for summary disposition upon finding that Sauer was a governmental employee. That finding was based on the fact that he worked for msu and was acting within the scope of his employment when he examined and operated on Janet Vargo because residents under Sauer’s tutelage were involved in this case and, as part of his employment, Sauer must maintain his medical *393skills as well as teach residents. The court also found that because plaintiff failed to allege facts amounting to gross negligence and no proprietary function was involved, Sauer was entitled to summary disposition pursuant to MCR 2.116(C)(10).1 Plaintiff appeals, and we affirm.

For the first time, plaintiff challenges the constitutionality of § 7 of the governmental tort liability act, MCL 691.1407; MSA 3.996(107), claiming that it violates equal protection guarantees because it fails to treat all university-employed physicians in Michigan in a like manner with respect to governmental immunity. Issues raised for the first time on appeal, including constitutional challenges, are not ordinarily subject to appellate review. Michigan Up & Out Of Poverty Now Coalition v Michigan, 210 Mich App 162, 167; 533 NW2d 339 (1995). However, because plaintiff raises an issue of first impression in Michigan, we will address this issue.
Sections 7(2) and 7(4) of the governmental tort liability act delineate who is entitled to receive governmental immunity from tort liability and what hospitals are excepted from this grant of immunity, respectively:_
*394(2) Except as otherwise provided in this section, and without regard to the discretionary or ministerial nature of the conduct in question, each officer and employee of a governmental agency, each volunteer acting on behalf of a governmental agency, and each member of a board, council, commission, or statutorily created task force of a governmental agency shall be immune from tort liability for injuries to persons or damages to property caused by the officer, employee, or member while in the course of employment or service or volunteer while acting on behalf of a governmental agency if all of the following are met:
(a) The officer, employee, member, or volunteer is acting or reasonably believes he or she is acting within the scope of his or her authority.
(b) The governmental agency is engaged in the exercise or discharge of a governmental function.
(c) The officer’s, employee’s, member’s, or volunteer’s conduct does not amount to gross negligence that is the proximate cause of the injury or damage. As used in this subdivision, "gross negligence” means conduct so reckless as to demonstrate a substantial lack of concern for whether an injury results.
* * *
(4) This act does not grant immunity to a governmental agency with respect to the ownership or operation of a hospital or county medical care facility or to the agents or employees of such hospital or county medical care facility. [MCL 691.1407(2), (4); MSA 3.996(107)(2), (4).]
Statutes are presumably constitutional and should be so construed unless their unconstitutionality is clearly apparent. Caterpillar, Inc v Dep’t of Treasury, 440 Mich 400, 413; 488 NW2d 182 (1992); Michigan Soft Drink Ass’n v Dep’t of Treasury, 206 Mich App 392, 401; 522 NW2d 643 (1994). Every reasonable presumption must be viewed in favor of constitutionality. Petrus v Dic*395kinson Co Bd of Comm’rs, 184 Mich App 282, 293; 457 NW2d 359 (1990). Under the state and federal constitutions, the Equal Protection Clause requires that persons in similar circumstances be treated alike. US Const, Am XIV; Const 1963, art 1, § 2; Frame v Nehls, 208 Mich App 412, 415; 528 NW2d 773 (1995). The type of classification and the nature of the interest affected will determine, however, the level of scrutiny that this Court must apply in evaluating plaintiffs equal protection challenge. Id. Because the statute does not create suspect classifications or impinge upon the exercise of fundamental rights, which would subject the statute to strict or intermediate scrutiny under the Equal Protection Clause of the Michigan or the United States Constitution, we must apply a rational basis test to the immunity statute. Doe v Dep’t of Social Services, 439 Mich 650, 662; 487 NW2d 166 (1992). We will uphold the statute as constitutional as long as the classification is rationally related to a legitimate governmental purpose. Id.; Feaster v Portage Public Schools, 210 Mich App 643, 651; 534 NW2d 242 (1995). The constitution " 'is offended only if the classification rests on grounds wholly irrelevant to the achievement of the [legislative] objective.’ ” Bissell v Kommareddi, 202 Mich App 578, 580; 509 NW2d 542 (1993), quoting McGowan v Maryland, 366 US 420, 425-426; 81 S Ct 1101; 6 L Ed 2d 393 (1961).
At the outset, we recognize that judicial construction of a statute is neither necessary nor permitted where the statutory language is clear and unambiguous. Skybolt Partnership v City of Flint, 205 Mich App 597, 602; 517 NW2d 838 (1994) . The Legislature is also presumed to intend the meaning plainly expressed in a statute. Id. Further, while the grant of governmental immunity is broad, any exceptions to that grant of *396immunity are narrowly construed. Wade v Dep’t of Corrections, 439 Mich 158, 166; 483 NW2d 26 (1992).
With regard to the public hospital exception to governmental immunity contained in § 7(4), we believe that the statutory language is clear: those employees of a hospital owned or operated by a governmental agency are excepted from the broad grant of immunity bestowed on other governmental employees in § 7(2). St. Lawrence Hospital is not owned or operated by msu; consequently, the equally unambiguous grant of immunity in § 7(2) applies to Sauer, as long as Sauer satisfies the three requirements set forth in subsections 7(2)(a), (b), and (c).
Plaintiff argues that the statute creates two classes of state university-employed physicians and treats them in a disparate fashion. According to plaintiff, under § 7(4), University of Michigan (u of m) physicians teaching and working at the University of Michigan Hospital are not entitled to immunity for medical malpractice, while Michigan State University (msu) physicians teaching and working at private hospitals (in the absence of a university-run hospital offering inpatient, overnight care) are immune from tort liability. We agree that teaching physicians employed by u of m and msu are both serving the same governmental function: teaching the human sciences to medical students, as authorized by their respective enabling statutes.2 Nothing in the legislative analysis of 1986 PA 175, which enacted the hospital exception to governmental immunity in § 7(4), explains the rationale behind this exception. This Court has stated that § 7(4) was adopted to rectify the inequity noted in Hyde v Univ of Michigan Bd of *397Regents, 426 Mich 223, 244-246; 393 NW2d 847 (1986), i.e., that persons injured by identical conduct in public and private facilities had different rights of recovery. Jamieson v Luce-Mackinac-Alger-Schoolcraft Dist Health Dep't 198 Mich App 103, 111-112; 497 NW2d 551 (1993). Plaintiffs challenge to § 7, however, focuses on the other half of this equation: the party against whom recovery can be pursued.
Under a rational basis test, we believe that the distinction created by §§7(2) and 7(4) between governmental employees who are university professors working at government-owned hospitals and university professors working at private hospitals passes constitutional muster. It is not our function to determine the wisdom, need, or appropriateness of the hospital exception in §7(4) in conducting this inquiry. Thus, although we recognize the arguably inequitable distinction pointed out by plaintiff, the statutory scheme is nonetheless rationally related to a legitimate governmental purpose: i.e., the state will permit governmental employees to be sued in tort where they presumably have input regarding or control over operations at the government-run hospital where the alleged malpractice occurs. See Doe, supra; Feaster, supra. Thus, governmental employees working at private hospitals as part of their governmental function who have no input or control regarding hospital operations cannot be sued for malpractice occurring at the private hospital. Also, extending immunity to physicians under these circumstances encourages medical schools to become involved in providing medical care in their communities when the school does not own or operate its own hospital or medical facility. Because legislation is rational if any state of facts either known or reasonably assumed can support *398it, and the existence of inequity in its application does not make it irrational, we believe that MCL 691.1407; MSA 3.996(107) survives the rational basis test and does not violate equal protection guarantees. Doe, supra; Bissell, supra.

Plaintiff also argues that the trial court erred in granting Sauer statutory immunity under §7(2) because, first, the administration of medical care is not a governmental function, second, Sauer was not acting within the scope of his employment and engaging in the discharge of a governmental function when the malpractice occurred, and, third, further discovery may have established that msu was operating a hospital, thereby removing Sauer’s cloak of governmental immunity. We disagree.
This Court reviews questions of law de novo. Westchester Fire Ins Co v Safeco Ins Co, 203 Mich App 663, 667; 513 NW2d 212 (1994). In deciding motions for summary disposition under MCR 2.116(C)(7) based upon governmental immunity, we must consider all documentary evidence submitted by the parties, accept all well-pleaded allegations as true, and view those allegations most favorably to the nonmoving party to determine whether the defendant is entitled to judgment as a matter of law. To defeat the motion, the plaintiff must allege facts that call into play an exception to governmental immunity. Wade, supra at 163.
Under the governmental tort liability act, msu, Sauer’s employer, is a governmental agency. MCL 691.1401(c), (d); MSA 3.996(101)(c), (d); see also Const 1963, art 8, § 4. MCL 390.101; MSA 15.1121 states that msu "shall provide the inhabitants of this state with the means of acquiring a thorough *399knowledge of [various arts and sciences] and to this end it shall afford such instruction in science, art and literature as, in the judgment of its governing body, will promote the object of the institution.” Further, MCL 691.1401(f); MSA 3.996(101)(f) defines "governmental function” as "an activity which is expressly or impliedly mandated or authorized by constitution, statute, local charter or ordinance, or other law.” Ross v Consumers Power Co (On Rehearing), 420 Mich 567, 620; 363 NW2d 641 (1984); Codd v Wayne Co, 210 Mich App 133, 135; 537 NW2d 453 (1995). Indeed, instructing medical students in the human sciences is an activity impliedly mandated by statute. We agree that a specific statutory provision mandating or authorizing msu to educate its medical students through clinical residencies at private community hospitals need not exist to satisfy the governmental function test. See, e.g., Hyde, supra at 253. Thus, the trial court did not clearly err in finding that training medical residents at St. Lawrence Hospital was part of the governmental function of the MSU College of Human Medicine under subsection 7(2)(a). See also Richerson v United States of America, unpublished order of the United States District Court, Eastern District of Michigan, Southern Division, entered November 13, 1995 (Docket No. 95-CV-70228-DT).
We also agree that Sauer was acting within the scope of his employment and furthering this governmental function, as required by subsection 7(2) (b), when the alleged malpractice occurred. As a professor at the MSU College of Human Medicine and as a physician who has staff privileges at St. Lawrence Hospital based solely upon his involvement with the Msu/St. Lawrence Hospital Family Practice Residency Program, Sauer was performing his duties as a professor of medicine by assist*400ing and instructing the residents and doctors attending to Janet Vargo. Nothing in the record contradicts the conclusion that Sauer was acting within his professorial capacity when called upon to examine Janet Vargo and recommend a course of treatment for her because msu residents were involved in her treatment.3 Moreover, the record establishes that Sauer was not paid by St. Lawrence Hospital, that patients treated by residents and teaching physicians paid msu for the services rendered at the private hospital, that Sauer did not have a private obstetrical or gynecological practice outside the MSU College of Human Medicine, and that he was on call for the msu family practice residents. Given that Sauer’s examination of Janet Vargo occurred as a result of his involvement in the Msu/St. Lawrence Hospital Family Practice Residency Program, we believe that the trial court did not err in finding that Sauer, a governmental employee, was engaged in the exercise of a governmental function and his conduct did not amount to gross negligence that was the proximate cause of Janet Vargo’s death.4 Thus, the trial court properly granted Sauer’s motion for summary disposition pursuant to MCR 2.116(C)(7) on the basis of governmental immunity under § 7(2).
hi
Finally, plaintiff asserts that the trial court erred in granting summary disposition because *401further discovery could have shown that msu was operating a "hospital,” as that term, is defined in § 7(4). We disagree. Summary disposition is premature if discovery of a disputed issue is incomplete. Summary disposition is appropriate, however, if there is no fair chance that further discovery will result in factual support for the nonmoving party. Mackey v Dep’t of Corrections, 205 Mich App 330, 333; 517 NW2d 303 (1994). In this case, discovery ended three months before the summary disposition hearing, so summary disposition was not premature. Moreover, even if it were established that a contract existed between msu and St. Lawrence Hospital creating the residency program or providing that msu would operate the family practice department at the hospital, Sauer would still be entitled to immunity based on (1) his status as an msu employee, and (2) our conclusion that a department within a hospital does not constitute a "hospital” or "facility” as defined in subsection 7(4)(b). See Rambus v Wayne Co General Hosp, 193 Mich App 268, 273; 483 NW2d 455 (1992), reaffirmed (On Rehearing), 197 Mich App 480; 495 NW2d 835 (1992).
Affirmed.
Corrigan, P.J., concurred.Notably, the trial court also stated in dicta that it was concerned about unfair legislatively created distinctions with respect to governmental immunity. For example, the court stated that under MCL 691.1407(4); MSA 3.996(107)(4), which excludes from immunity a government-owned hospital or medical care facility and its employees, a person injured at the University of Michigan Hospital could have knowingly submitted to having residents examine him, and he would be permitted to sue in tort for any damages sustained during the course of treatment. The same person admitted into a private hospital' such as St. Lawrence, however, may not expect to be examined by msu residents and teachers and could not sue for the same damages. The trial court stated: "I think this is an area that the Legislature has, frankly, created the opportunity for unfair treatment. . . . [I]f there’s going to be governmental immunity, it should be for persons who are similarly situated.”
See MCL 390.2; MSA 15.902, MCL 390.8; MSA 15.908, MCL 390.101; MSA 15.1121, MCL 390.661; MSA 15.1104(1).
It is irrelevant that defendant Dr. James Rawlinson, one of the physicians treating Vargo, contacted Sauer and requested a consultation. According to Sauer’s uncontroverted testimony in his affidavit, he was on caí. to St. Lawrence to assist msu residents who were participating in the family practice residency program and who were assisting in Janet Vargo’s care.
The issue whether Sauer was grossly negligent as defined in subsection 7(2)(c) is not disputed here.
