Pursuant to Maryland Code (1973, Repl. Vol. 2002), Courts and Judicial Proceedings Article, § 12 — 303(3)(i), 1 Appellants (Defendants below), the Honorable Robert L. Ehrlich, Jr., the Honorable S. Anthony McCann, and the Honorable Nancy Kopp, each sued in his or her official capacity as Governor of Maryland, Secretary of the Maryland Department of Health and Mental Hygiene (“DHMH”), and State Treasurer, respectively, sought appellate review of a preliminary injunction issued by the Circuit Court for Montgomery County. The injunction essentially ordered the payment of medical assistance benefits to Appellees (Plaintiffs in the Circuit Court), comprised of Flor Perez and Ana Perez (minors, by their father and next friend, Fidel Perez); Brayan Herrera, Osvaldo Herrera, and Leslie Herrera (minors, by their mother and next friend, Martha Herrera); and Gabriel Ntitebem, Henry Anu, and Vitalis Atemafac (minors, by their mother and next friend, Ajong Pamela Nkahinjo), 2 under the Medical Assis *697 tance Program, Maryland Code (1982, Repl. Vol. 2005), Health-General Article, § 15-103. 3
Appellees, all residents of Maryland, are lawful permanent resident aliens of the United States who immigrated from their respective foreign countries on or after 4 August 2003. Section 15-103(a)(2)(viii) provides that the State
[sjhall provide, subject to the limitations of the State budget and any other requirements imposed by the State, comprehensive medical care and other health care services for all legal immigrant children under the age of 18 years and pregnant women who meet Program eligibility standards and who arrived in the United States on or after August 22, 1996, the effective date of the federal Personal Responsibility and Work Opportunity Reconciliation Act [8 U.S.C. § 1601, et. seq. (1996) (hereinafter “PRWORA”).]
The Circuit Court granted the preliminary injunction based, in part, upon its conclusion that Appellees likely would prevail on their claim that the failure of. the State of Maryland to appropriate funds for Fiscal Year (“FY”) 2006 (1 July 2005 through 30 June 2006) for medical benefits, as provided under § 15 — 103(a)(2)(viii), to resident alien children and resident alien pregnant women in Maryland who immigrated to the United States on or after 22 August 1996, while funding similar benefits to citizens and resident aliens in Maryland who immigrated lawfully before 22 August 1996, violated
*698
Article 24 of the Maryland Declaration of Rights.

Appellants filed a timely appeal with the Court of Special Appeals. We issued, on our initiative, a writ of certiorari to the Court of Special Appeals,
Ehrlich v. Perez,
1. Whether Appellants violated Article 24 of the Maryland Declaration of Rights by not appropriating monies for the State-funded Medical Assistance Program to resident alien children and pregnant women who immigrated to the United States on or after 22 August 1996 (a group not otherwise covered under federal analogous law — Medicaid) where federal law, enacted under the authority held by the Federal Government over national immigration policy, expressly provides the States with complete discretion to provide wholly State-funded medical benefits to this class of legal resident aliens.
2. Whether the Circuit Court was authorized to order, through a preliminary injunction, Appellants to reinstate medical benefits to Appellees, as prescribed under the Medical Assistance Program, both retrospectively from 26 October 2005, the date the original Complaint and Motion for Preliminary Injunction were filed, back to 1 July 2005 and prospectively from 26 October 2005 until final disposition of the case.
I.
In its written memorandum opinion explaining why it issued the preliminary injunction, the Circuit Court summarized the *699 relevant factual and legislative background as follows, in pertinent part:
FACTUAL BACKGROUND
Based solely on the original Complaint filed on October 26, 2005, the Plaintiffs are comprised of Flor Perez and Ana Perez (by their father and next friend, Fidel Perez); Brayan Herrera, Osyaldo Herrera, and Leslie Herrera (by their mother and next friend, Martha Herrera); and Gabriel Ntitebem, Henry Anu, and Vitalis Aternafac (by their mother and next friend, Ajong Pamela Nkahinjo). They have filed their original Complaint against the Defendants, who are comprised of the Governor (Robert L. Ehrlich, Jr.), the Secretary of the Department of Health and Mental Hygiene (S. Anthony McCann), and the Treasurer (Nancy Kopp) for one count of Violation of Maryland Declaration of Rights. On the day of the scheduled hearing for the Request for a Preliminary Injunction, the Plaintiffs filed an Amended Complaint, identifying five additional Plaintiffs. However, for purposes of this Preliminary Injunction, the Court viewed the case in light of the facts as set forth in the original Complaint.
Generally, the Plaintiffs’ Complaint alleges that the State of Maryland, through Governor Ehrlich’s budgetary authority, discriminated and otherwise unconstitutionally denied certain persons living in the State access to health care [under § 15-103, called the Medical Assistance Program]. The Plaintiffs[ ] further contend that the State relied upon the classification of “alienage” in making their decision to deny health care coverage of these individuals.
On April 7, 2005, the General Assembly enacted the fiscal year 2006 Budget. In mid-June, the Department of Health and Mental Hygiene mailed a notice to all resident alien recipients, including the Plaintiffs named herein, to inform them that their current benefits would end starting June 30, 2005 as a result of the Governor’s decision to eliminate such funding. The notice provided for a right to appeal the *700 termination of coverage to the Office of Administrative Hearings (OAH).[ 6 ] The notice also informed the recipients that there were alternative options for publicly subsidized health care coverage. Specifically, the recipients were advised to apply to their local health department for Maryland Children’s Health Program (MCHP) coverage if they are under 19 years of age. The Department also notified the local health departments in each jurisdiction that funding for this coverage group had been eliminated from the fiscal year 2006 Budget and thereby instructed the local departments to assist persons in this group with finding similar care wherever possible.
Despite the Department’s efforts, Plaintiffs, and others similarly situated, have been precluded as a result of their own indigence. Coupled with their inability to pay, most of these programs are unable to provide such necessary services that were previously covered under the Medical Assistance Program. Often times these alternative programs are simply closed to new patients.
*701 LEGISLATIVE BACKGROUND
In order to thoroughly understand the issues at hand, it is imperative that this Court outline the Federal and State statutory programs upon which the Plaintiffs previously relied for their health care services.
A. FEDERAL PROGRAMS
i Medicaid
Medicaid is a federal program established by Title XIX of the Social Security Act. See 42 U.S.C. §§ 1396-1396v. “Congress has authorized grants to states for the purpose of enabling each state, as far as practicable under the conditions in such state, to furnish medical assistance to persons who are eligible thereof.” 81 C.J.S. Social Security and Public Welfare § 247. Eligible individuals include certain indigent persons, such as the “aged,” “blind” and “disabled.” Medicaid also provides coverage for pregnant women and children who fall below a certain income threshold, in addition to covering medically needy persons, such as elderly persons who are confined to nursing homes and whose medical expenses have exhausted their other assets. If a state chooses to take part in the federal Medicaid program, it must comply with the requirements set forth in Title XIX and its implementing regulations in order to receive federal matching funds. In Maryland, the federal matching fund is about 50% of the total expenditures. See Federal Matching Shares for Medicaid, 68 Fed. Reg. 67676 (Dec. 3, 2003).
ii. Federal Welfare Reform Act
On August 22, 1996, Congress enacted legislation that significantly impacted Medicaid coverage for select individuals residing in the U.S. The Personal Responsibility and Work Opportunity Reconciliation Act of 1996, generally know as the “Welfare Reform Act,” was a program designed to further the national immigration policy of “self-sufficiency.” 8 U.S.C. § 1601(1). The statement of national policy concerning welfare and immigration reads, in part: “It is a compelling government interest to remove the incentive for *702 illegal immigration provided by the availability of public benefits.” 8 U.S.C. § 1601(6).
The Act ultimately rendered non-qualified aliens ineligible for Federal Medicaid benefits, while also creating two categories for qualified aliens.
Ali[e]ssa v. Novello,
B. MARYLAND STATE PROGRAMS
i. Maryland’s Welfare Innovation Act
“State participation in Medicaid is voluntary, but if a state participates, it must comply with the federal statutes and regulations governing the programs. However, there is no legal prohibition preventing a state legislature from awarding medical assistance benefits on its own, independent of federal reimbursement.” 81 C.J.S. Social Security and Public Welfare § 247;
see also San Lazaro Ass’n, Inc. v. Connell,
*703
v. Haveman,
“[s]ubject to the limitations in the State budget and any other requirements imposed by the State, comprehensive medical care and other health care services for all legal immigrant children under the age of 18 years and pregnant women who meet Program eligibility standards and who arrived in the U.S. on or after August 22, 1996, the effective date of the federal Personal Responsibility and Work Opportunity Reconciliation Act.”
Md. Ann. Code, Health-General Article § 15-103(a)(2)(viii). The [statutory provision] provides for medical assistance to this newly excluded class of alien, pregnant women and children deemed ineligible for non-emergency, Federal Medicaid benefits. Although the Maryland State Medicaid program, along with federal matching funds, provides the same medical services as available under the Welfare Innovation Act to both citizens and resident aliens who meet the five-year residency requirement, this new provision is limited to those aliens for whom federal Medicaid eligibility was eliminated by the Welfare Reform Act. Therefore, it is funded entirely with state funds. Here, the State used the authority granted by Congress under the Welfare Reform Act. [The benefits established by the adoption of § 15-103] became known as the Medical Assistance Program.
C. THE MARYLAND STATE BUDGET
Every year in Maryland, the Governor submits a proposed budget bill to the General Assembly containing the proposed budgetary measures for the State government for the following fiscal year. Unlike a “give and take” relationship between the Legislative and Executive branches ..., the General Assembly is free to reduce the Governor’s budget *704 ary proposals, but it may not increase or amend. See MD Const., Art. 3, § 52(6).
Except as expressly mandated by the Constitution or statutes, the Governor has complete discretion over the inclusion of appropriations in the Budget and the amount for the executive branch. The constitutional mandates relate to funding the public schools, redemption of the State debt, the payment of certain salaries. With the consent of the General Assembly, the Governor can amend or supplement the Budget Bill prior to its passage. Subject to certain exceptions and limitations, the General Assembly has express power only to strike or reduce appropriations in the Budget Bill. However, this express power includes the implied power to condition or qualify.
Richard E. Israel, Archives of Maryland Online, “Maryland’s Budget Process,” [] www.mdarchives.state.md.us/ megafile/msa/speccol/sc2900/sc2908/html/budget.html (last visited December 29, 2005). Despite its ability to “condition” or “qualify” the revisions in the proposed Budget, the General Assembly is precluded from deciding that a particular appropriation is under funded. Maryland’s Legislative branch is powerless to realign the Governor’s proposed spending like[, for example,] the legislatures in New York and Virginia.
iv. The Fiscal Year 2006 Maryland Budget: The “Carve-Out” Provision
Recently, the fiscal year 2006 Budget as proposed by the Governor eliminated funding for the Medical Assistance Program. This budget cut essentially carved the aforementioned category of legal, resident aliens out of the State’s final Budget Bill. There are currently no funds available in the budget for the women, who were not pregnant, and children, both who were in this program at the beginning of the current fiscal year — however, [§ 15-103] remains in force. Despite their ability to condition or qualify certain budgetary measures, the Maryland General Assembly never had the option to restore funding to the program, as this *705 would have resulted in the General Assembly overstepping its Constitutional boundaries!.] [ 7 ]
On 12 January 2006, the Circuit Court issued a written memorandum opinion and order granting Appellees’ Motion for Preliminary Injunction. In its opinion, the Circuit Court explained its view that Appellees satisfied the four requisite elements for issuance of a preliminary injunction. Specifically, the trial court determined that: the balance of convenience clearly favored Appellees because they suffered great harm as a result of the State’s budget cut; Appellees were irreparably injured as a result of the State’s action because they were unable to afford health care without the unfunded State assistance; the public interest “is best served if the [State is] required to provide benefits to [Appellees] for which they are currently entitled [under § 15 — 103(a)(2)(viii)];” and, finally, Appellees demonstrated that they likely would succeed on the merits of their Article 24 equal protection claim. It is this latter determination to which most of the parties’ attentions are directed on appeal.
With regard to the likelihood of success on the merits, the Circuit Court explored the principles of equal protection under Article 24. While acknowledging that Appellees are “appropriately classified as ‘aliens,’ ” the court determined that the allegations pertained to the denial of Appellees’ equal protection right “based on their status as individuals who are legally entitled to State funding [under § 15-103(a)(2)(viii) ] — not as a suspect class.” 8 Thus, rather than focusing upon the “ ‘alien- *706 age’ classification” to determine the appropriate standard of review to apply to the State action, the court looked to the “Governor’s decision to cut funding to a legally entitled group of individuals.... ” Recognizing that, in considering equal protection challenges, a rational basis standard of review generally applies to examining State action with regard to economic and social welfare issues, the Circuit Court determined that the “impact on [Appellees] ... is far too disparate to ignore ‘alienage’ as an underlying classification.... ” Therefore, the court reviewed the constitutional claim as to the budget cut under a strict scrutiny standard. The court then concluded that the State failed to advance a sufficient basis “as to how [its] budgetary interest was compelling enough to overcome strict scrutiny.” The court noted that “cutting welfare funds to legally entitled individuals is certainly not narrowly tailored enough to overcome strict scrutiny.” Consequently, the Circuit Court reasoned that the State failed to meet its burden and determined that Appellees likely would succeed on the merits of their equal protection claim.
The Circuit Court ordered “that the benefits payable under the Health-General Article § 15-301, et seq. previously denied to [Appellees] be ... retroactively reinstated” and further ordered “that the benefits payable under the Health-General Article § 15-301, et seq. be ... reinstated until final disposition of this action.” Appellants filed with the Circuit Court a Notice of Appeal to the Court of Special Appeals, an Answer, and a Motion for Stay Pending Appeal on 19 January 2006. Appellees filed an opposition on 23 January 2006. That same day, the Circuit Court issued a separate order staying the part of the preliminary injunction that ordered payment of retrospective benefits, but denied a stay in all other respects.
The Court of Special Appeals issued an order on 7 February 2006 staying the judgments entered on the Circuit Court’s orders, pending appeal, without prejudice to the right of any *707 current Appellee, at that time, to seek from the Circuit Court “appropriate limited relief from the stay upon a full and complete showing that (1) in order to avoid a serious risk to his or her health, the Appellee must receive particularized medical treatment prior to April 7, 2006, (2) the Appellee would have coverage for this treatment if the Orders of the circuit court had not been stayed by this Order, and (3) the Appellee will not be provided with necessary treatment unless the circuit court grants appropriate relief.”
After Appellants’ brief on the merits was filed in the intermediate appellate court, but before further action could be taken by that court, we issued a writ of certiorari to the Court of Special Appeals on 9 March 2006.

General Standards Applicable to the Review of the Grant of Injunctive Relief

(1) the likelihood that the plaintiff will succeed on the merits; (2) the “balance of convenience” determined by whether greater injury would be done to the defendant by granting the injunction than would result from its refusal; (3) whether the plaintiff will suffer irreparable injury unless the injunction is granted; and (4) the public interest.

The Parties’ Main Arguments
A.
Level of Judicial Scrutiny to be Accorded to the Appellants’ Action in the Equal Protection Analysis
Appellants assert that the Circuit Court erred in granting the preliminary injunction because Appellees lacked a real probability of prevailing on the merits of their Article 24 claim. Appellants contend that their failure to appropriate funds for medical benefits to a subcategory of legal aliens who, by virtue of congressional action under PRWORA, were ineligible to receive federal medical benefits is subject to rational basis review under the Supremacy Clause and withstands Appellees’ equal protection challenge under that standard. Under the Supremacy Clause, Appellants contend, consideration of Appellees’ state constitutional claim requires judicial deference to Congress’ plenary power over naturalization and immigration policy. Relying on
Mathews v. Diaz,
Although conceding that the State may not exercise independently a like power over aliens, Appellants maintain that, in adopting the Welfare Reform Act, Congress prescribed a uniform rule for the treatment of an alien sub-class in regard to the provision of medical benefits, which Maryland could follow, citing as support
Plyler v. Doe,
Appellants offer that the reason for the Maryland budget cut was to achieve a cost savings of seven million dollars (equal to the amount of funds appropriated in the Medical Assistance Program in Fiscal Year (“FY”) 2005, inclusive of the estimated number of individuals of the legal alien sub-class to which Appellees belong) of the four billion dollar budget appropriated for medical assistance health care costs generally. They maintain that Congress provided a “sufficient showing of a facially legitimate and bona fide reason” to discriminate against the relevant alien sub-class in the provision of federal Medicaid benefits, by including legislative findings in the Welfare Reform Act. These legislative findings provide that the provisions of the Welfare Reform Act were necessary to achieve the national immigration policy of encouraging self-sufficiency and removing incentives for illegal immigration. The Act’s findings also provide that a State choosing not to provide non-emergency medical benefits to aliens excluded from federal benefits by the Welfare Reform Act, as Maryland did in the FY 2006 Budget, “shall be considered to have chosen the least restrictive means available for achieving the compelling governmental interest of assuring that aliens be self-reliant in accordance with national immigration policy,” quoting 8 U.S.C. § 1601(7). Appellants argue that the Supremacy Clause restrains Maryland State courts from disregarding Congress’ direction in this area of immigration policy.
Finally, as to the correct standard of review to be applied to the Article 24 challenge, Appellants assert that the Welfare Reform Act grants Maryland the ability to determine whether and to what extent it will use State funds to provide non- *711 emergency medical benefits to resident aliens who do not meet the five-year residency requirement, see 8 U.S.C. §§ 1622(a), 1624(a), provided that any prohibitions, limitations, or restrictions imposed by Maryland are not more restrictive than the prohibitions, limitations, or restrictions imposed under comparable federal programs, see 8 U.S.C § 1624(b). 9
Appellees, on the other hand, maintain (as Appellants seem to concede) that the budget cut of State-funded medical assistance to certain resident aliens was a classification based upon alienage, and is therefore a suspect classification, relying on
Murphy v. Edmonds,
Appellees bring to our attention that a similar medical assistance funding restriction adopted in New York, based on alienage, was found to be unconstitutional, under state and federal equal protection guarantees, in
Aliessa v. Novello,
B.
Judicial Action Possibly Implicating State Budget Appropriations Limitations
Appellants claim that the Circuit Court lacked the authority to issue a preliminary injunction requiring expenditure of State funds to pay for medical benefits that were not appropriated in the FY 2006 Budget. Appellants’ argument is based on the contention that Maryland law does not permit constitutional and statutory requirements governing public expenditures to be overborne by a violation of Article 24 of the Declaration of Rights.
Appellants characterize the Circuit Court’s order as an illegal order for the expenditure of unappropriated funds, in contravention of Article III, § 32 of the Maryland Constitution (which provides that State funds must be appropriated through the comprehensive executive budget procedure pursuant to Article III, § 52);
see also Md. Act. for Foster Child, v. State,
Appellants contend that the Circuit Court’s “departure from the requirements of the Constitution” in granting the prelimi
*714
nary injunction is not justified by a likely equal protection violation under Article 24 because the Maryland Declaration of Rights would not trump the express demands of the Constitution. Rather, Appellants posit that if there exists a conflict between Article 24 and the specific provisions of the Maryland Constitution governing budget and appropriations requirements, then the specific provisions prevail, relying on
Commission on Medical Discipline v. Stillman,
Characterizing the Circuit Court’s preliminary injunction order as an appropriation of funds from the State Treasury, Appellants maintain that the constitutional prerequisites for a lawful expenditure of State funds are not satisfied here and that there has been no appropriation for the benefits that the preliminary injunction orders be paid. Thus, Appellants argue, the payment of funds may not be ordered or made from the State Treasury to satisfy the preliminary injunction.
Appellees counter that the Circuit Court possessed the authority to fashion the preliminary injunction as it did. First, Appellees assert that the Governor’s budgetary authority, although far-reaching, is subject to fundamental constitutional limitations, including Article 24. This Court can give both Article 24 of the Declaration of Rights and Article III, §§52 and 32 of the Maryland Constitution full effect, as part of an integrated document, by requiring the Executive not to violate the Declaration of Rights in the course of exercising his budgetary authority, a reading that Appellees posit is required by both the history of the Budget Amendment and its subsequent interpretations by this Court. Appellees also contend that Article III, § 32 pertains to legislative orders, not judicial orders, relying on
Dorsey, supra,
The Circuit Court did not order the direct expenditure of specific funds; rather the injunctive order “was designed to remedy a constitutional violation and protect [Appellees] from irreparable harm, while leaving the mechanism for rectifying the constitutional violation entirely up to Appellants.” Appellees argue that because the Budget Bill provides for a lump sum appropriation, of which some small portion is restricted for specific purposes (for example, the FY 2005 budget provided for a total of approximately $4 billion for medical care provider costs, of which some portion is used for medical assistance), the general language of the appropriation leaves significant leeway to the DHMH to move funds within broad categorical appropriations in order to satisfy the court’s order. Appellees also highlight that, in recent years, when the State’s medical assistance expenditures exceeded budget projections, Appellants did not deny coverage to eligible recipients, but instead, routinely included in the annual Budget Bill amounts to cover the prior year’s deficiency.
IV.
We consider first whether the failure to fund as to Appellees (and the sub-class of legal aliens of which they are a part) the Medical Assistance Program for FY 2006, i.e., the budget cut, violates the principles of equal protection embodied in Article 24 of the Maryland Declaration of Rights. Article 24 and the Equal Protection Clause of the Fourteenth Amendment are in pan
materia,
and we generally apply them in like manner and to the same extent.
Hornbeck v. Somerset Co. Bd. of Educ.,
Differing standards have evolved for reviewing classifications challenged under the equal protection guarantees:
In most instances when a governmental classification is attacked on equal protection grounds, the classification is reviewed under the so-called “rational basis” test. Generally under that test, a court “ ‘will not overturn’ ” the classification “ ‘unless the varying treatment of different groups or persons is so unrelated to the achievement of any combination of legitimate purposes that [the court] can only conclude that the [governmental] actions were irrational.’ ” Gregory v. Ashcroft,501 U.S. 452 , [471],111 S.Ct. 2395 , 2406,115 L.Ed.2d 410 , 430 (1991), quoting Vance v. Bradley,440 U.S. 93 , 97,99 S.Ct. 939 , 943,59 L.Ed.2d 171 , 176 (1979). See Pennell v. San Jose,485 U.S. 1 , 14,108 S.Ct. 849 , 859,99 L.Ed.2d 1 , 16 (1988). A statutory classification reviewed under the rational basis standard enjoys a strong presumption of constitutionality and will be invalidated only if the classification is clearly arbitrary. See, e.g., Briscoe v. P.G. Health Dep’t,323 Md. 439 , 448-449,593 A.2d 1109 , 1113-1114 (1991); Hargrove v. Board of Trustees, [ ] 310 Md. [406, 423,529 A.2d 1372 , 1380 (1987)]; State v. Wyand, [ ] 304 Md. [721, 726-27,501 A.2d 43 , 46 (1985)]; Whiting-Turner Contract. Co. v. Coupard,304 Md. 340 , 352,499 A.2d 178 , 185 (1985); Department of Transportation v. Armacost,299 Md. 392 , 409,474 A.2d 191 , 199 (1984); State v. Good Samaritan Hospital,299 Md. 310 , 328,473 A.2d 892 , 901, appeal dismissed,469 U.S. 802 ,105 S.Ct. 56 ,83 L.Ed.2d 7 (1984); Montgomery Co. v. Fields Road,282 Md. 575 , 579-580,386 A.2d 344 , 347 (1978).
*717 Where, however, a statutory classification burdens a “suspect class” or impinges upon a “fundamental right,” the classification is subject to strict scrutiny. Such statutes will be upheld under the equal protection guarantees only if it is shown that “ ‘they are suitably tailored to serve a compelling state interest.’ ” Broadwater v. State,306 Md. 597 , 603,510 A.2d 583 , 585 (1986), quoting Cleburne v. Cleburne Living Center,473 U.S. 432 , 440,105 S.Ct. 3249 , 3254,87 L.Ed.2d 313 , 320 (1985). See, e.g., Graham v. Richardson,403 U.S. 365 , 372,91 S.Ct. 1848 , 1852,29 L.Ed.2d 534 , 541-542 (1971) (“classifications based on alienage, like those based on nationality or race, are inherently suspect and subject to close judicial scrutiny”); Shapiro v. Thompson,394 U.S. 618 , 634,89 S.Ct. 1322 , 1331,22 L.Ed.2d 600 , 615 (1969) (“in moving from State to State ... appellees were exercising a constitutional right, and any classification which serves to penalize the exercise of that right, unless shown to be necessary to promote a compelling governmental interest, is unconstitutional”); Kramer v. Union Free School District,395 U.S. 621 , 627,89 S.Ct. 1886 , 1889-1890,23 L.Ed.2d 583 , 589 (1969) (classification impinging upon the right to vote). See also O.C. Taxpayers v. Ocean City,280 Md. 585 , 594,375 A.2d 541 , 547 (1977) (“we are ... here dealing with the right to vote, and thus the classification is subject to ... special scrutiny”).
Finally, there are classifications which have been subjected to a higher degree of scrutiny than the traditional and deferential rational basis test, but which have not been deemed to involve suspect classes or fundamental rights and thus have not been subjected to the strict scrutiny test. Included among these have been classifications based on gender (Mississippi University For Women v. Hogan,458 U.S. 718 , 723,102 S.Ct. 3331 , 3335,73 L.Ed.2d 1090 , 1097 (1982); Craig v. Boren,429 U.S. 190 ,97 S.Ct. 451 ,50 L.Ed.2d 397 (1976); Reed v. Reed,404 U.S. 71 ,92 S.Ct. 251 ,30 L.Ed.2d 225 (1971)), 10 discrimination against illegitimate *718 children under some circumstances (Weber v. Aetna Casualty & Surety Company,406 U.S. 164 ,92 S.Ct. 1400 ,31 L.Ed.2d 768 (1972); Levy v. Louisiana,391 U.S. 68 ,88 S.Ct. 1509 ,20 L.Ed.2d 436 (1968)), a classification between children of legal residents and children of illegal aliens with regard to a free public education (Plyler v. Doe,457 U.S. 202 , 217-218, 224,102 S.Ct. 2382 , 2395, 2398,72 L.Ed.2d, 786 , 799-800, 803 (1982)), and a classification under which certain persons were denied the right to practice for compensation the profession for which they were qualified and licensed (Attorney General v. Waldron, supra,289 Md. at 716-728 ,426 A.2d at 947-954 ). (Some alterations in original).
Murphy,
Classifications based on alienage employed by a State “are inherently suspect and are therefore subject to strict judicial scrutiny whether or not a fundamental right is impaired.”
Graham,
Statutory discrimination within the larger class of legal resident aliens, providing benefits to some aliens, but not to others, is nonetheless a classification based on alienage.
Nyquist,
*720
Where a federal statute distinguishes between citizens and aliens (and sub-classes of aliens), the U.S. Supreme Court applies a more relaxed standard of review than the strict scrutiny standard of review applied to comparable State statutes. In
Mathews v. Diaz, supra,
Moreover, in
Mathews,
the Court contrasted the federal government’s power to enact laws governing aliens to the States’ lack of authority to do likewise. The Court noted that its decision in
Graham
supported its decision in
Mathews,
stating that “it is the business of the political branches of the Federal Government, rather than that of either the states or the Federal Judiciary, to regulate the conditions of entry and residence of aliens.”
Mathews,
*722 Appellants insist that we should apply a relaxed standard of scrutiny when deciding whether the budget cut undertaken by Appellants violated Article 24 of the Maryland Declaration of Rights, pursuant to the theory of the “uniform rule,” because a federal law (PRWORA) expressly grants to States the discretion whether to provide wholly State-funded medical benefits to the class of resident aliens who immigrated to the United States on or after 22 August 1996. Appellees counter by asserting that, because Congress left complete discretion to the States, we should apply the strict scrutiny standard to the State’s action because the federal statute did not provide a “uniform rule” to which the States are required to adhere in exercising that discretion. The “uniform rule” foundation for application of a relaxed scrutiny review of State action under equal protection attack has not been adopted previously in a reported Maryland case or U.S. Supreme Court decision.
Analysis of the question of whether the State action here is shielded by the “uniform rule” theory from what otherwise should be a strict scrutiny standard of review does not yield a succinct or ready answer. The U.S. Supreme Court has noted that it has “long recognized the preeminent role of the Federal Government with respect to the regulation of aliens within our borders.”
Toll v. Moreno,
*724 In conjunction with recognition of the exclusive power of the federal government to regulate aliens, the Supreme Court also expressed, on numerous occasions, reservations about Congress delegating that authority to the States. In 1889, the Supreme Court articulated generally those reservations:
The power of exclusion of foreigners being an incident of sovereignty belonging to the Government of the United States, as a part of those sovereign powers delegated by the Constitution, the right to its exercise at any time when, in the judgment of the Government, the interests of the country require it, cannot be granted away or restrained on behalf of anyone. The powers of Government are delegated in trust to the United States, and are incapable of transfer to any other parties.
Chae Chan Ping v. United States,
[pjerhaps Congress could induce wider state participation in school construction if it authorized the use of joint funds for the building of segregated schools. But could it seriously be contended that Congress would be constitutionally justified in such authorization by the need to secure state cooperation? Congress is without power to enlist state cooperation in a joint federal-state program by legislation which authorizes the States to violate the Equal Protection Clause. Katzenbach v. Morgan,384 U.S. 641 , 651 n. 10,86 S.Ct. 1717 ,16 L.Ed.2d 828 , 836 n. 10 (1966).

In
Graham v. Richardson, supra,
Assuming that the power over immigration and naturalization possessed by the federal government includes establishing a single, uniform, and articulated directive for treating aliens regarding State-only funded medical assistance benefits, such that we will employ a rational basis standard of review to a State’s elimination of State-only funded benefits for certain resident aliens,
15
we conclude that PRWORA prescribes no
*726
uniform rule in any event. Rather, Congress has provided discretion to the States with regard to their decisions whether to provide State-funded medical benefits, on the basis of alienage, to those resident aliens who do not meet the requirements for federal medical assistance. The grant of discretion, without more, is not a uniform rule for purposes of imposing only a rational basis test. The unbridled discretion afforded by Congress prevents us from characterizing the material provisions of PRWORA as “uniform.” In suggesting that a “uniform rule” principle exists, the U.S. Supreme Court unhelpfully declared only a one element requirement — that the rule prescribed by Congress be uniform. In
Plyler v. Doe,
*727
As the Court of Appeals of New York noted in
Aliessa v. Novello, supra,
Recent decisions from state and federal courts lend support for this conclusion. In
Aliessa,
the Court of Appeals of New York adopted a similar position on the “uniform rule” principle.
Aliessa,
The New York high court compared State and Congressional authority with regard to immigration and naturalization.
Aliessa,
This uniformity requirement for applying a relaxed scrutiny standard of review to State action in a somewhat similar context also has been noted by the U.S. Court of Appeals for the Ninth Circuit. In
Sudomir v. McMahon,
The Court in
Sudomir
distinguished its material facts from those in
Plyler
on the basis that the “State [in
Plyler]
had employed the federal classification ‘for
its own
discriminatory poliey[.]’”
Sudomir,
Because we conclude that PRWORA does not provide a “uniform rule” for subsequent State actions,
22
we shall
*731
employ a strict scrutiny standard of review in our consideration of the State action here that, in effect, discriminated in the provision of State-funded medical assistance benefits based on an alienage classification or sub-classification.
See also Kurti v. Maricopa County,
In
Shapiro v. Thompson, supra,
*732 The Court rejected this funding justification, under strict scrutiny analysis, stating that
[w]e recognize that a State has a valid interest in preserving the fiscal integrity of its programs. It may legitimately attempt to limit its expenditures, whether for public assistance, public education, or any other program. But a State may not accomplish such a purpose by invidious distinctions between classes of its citizens. It could not, for example, reduce expenditures for education by barring indigent children from its schools. Similarly, in the cases before us, appellants must do more than show that denying welfare benefits to new residents saves money. The savings of welfare costs cannot justify an otherwise invidious classification.
Shapiro,
With respect to the remaining three factors to be considered in acting on a preliminary injunction request, we conclude that the Circuit Court did not abuse its discretion in resolving them in favor of Appellees. First, considering Appellees’ personal interests and the burden to the State, the trial court determined that the relative cost to Appellees of searching for other medical coverage was substantial, but the cost to the State to maintain the cancelled program was relatively minimal. The balance of convenience, it was concluded, favored Appellees. Second, Appellees provided suffi *733 cient factual averments, if proven at trial, of their on-going medical needs and inability to obtain alternative health care, without State assistance, for the Circuit Court to find reasonably that Appellees likely would suffer irreparable injury unless the requested preliminary injunction was issued. Third, in light of the public policy goals of the Welfare Innovation Act, the Circuit Court did not abuse its discretion in concluding that the public interest was best served by requiring the State to provide benefits to “some of the most vulnerable segments of its population.” Consequently, the Circuit Court generally acted within the permissible range of its discretion in deciding to grant preliminary injunctive relief in favor of Appellees.
V.
We consider next whether the court properly ordered Appellants to reinstate medical benefits to Appellees, as prescribed under the Medical Assistance Program. The Circuit Court’s order of 12 January 2006 provided that the medical benefits be reinstated as of 1 July 2005. Additionally, the Circuit Court ordered that the medical benefits be reinstated prospectively from 26 October 2005, the date the original Complaint and Motion for Preliminary Injunction were filed, until final disposition of the case.
As we have noted previously, “injunctive relief is a preventive and protective remedy,
aimed a,t future acts,
and is not intended to redress past wrongs.”
El Bey v. Moorish Science Temple,
We conclude that the Circuit Court’s order for retrospective relief through a preliminary injunction was not appropriate. Here, the court’s order for retrospective reinstatement of medical assistance benefits was not a preservation of the status quo. Rather, it was, in effect, an award of past damages to Appellees. Damages, if any, may be awarded only upon disposition of the case upon the merits, not through the grant of a preliminary injunction. In the present case, the
*735
Circuit Court effectively awarded damages to Appellees in the form of undetermined retrospective medical assistance benefits without either a final adjudication on the merits of liability or a determination of actual damages, if any, suffered by Appellees.
See Benson v. State,
Appellants contend that the court lacks the authority to order the executive and legislature branches prospectively to reinstate medical assistance benefits to Appellees. Appellants arguments are misplaced. First, Appellants characterize the Circuit Court’s order as an illegal appropriation of funds. While Appellants note correctly that Article III §§ 32 and 52 of the Maryland Constitution provide a comprehensive executive budgetary procedure for appropriating monies, the order prospectively reinstating medical benefits to Appellees in the present case does not operate as an order directing the appropriation of specific funds. 25 Rather, the order serves as *736 a judicial determination that Appellants’ action warranted the issuance of a preliminary injunction because there is a likelihood that Appellants’ action was unconstitutional.
Second, Appellants argue that the Declaration of Rights does not overbear the express terms of the Constitution. If there were a conflict between Article 24 and the budget provisions of the Constitution, the more specific budget provisions would prevail. It is unclear to us why Appellants advance this argument when no issue has been presented that questions the validity of the budget and appropriations provisions of the Maryland Constitution. Assuming, as we do, that Appellants actually mean to argue that the equal protection guarantees of Article 24 do not apply to the budget appropriation process, we reject the argument because the executive and legislative budget authority is subject to the constitutional limitations of the Declaration of Rights.
See, e.g., Judy,
Third, and related to their second argument, Appellants contend that by providing expressly that the prohibition against unappropriated expenditures applies to “any order,”
*737
Article III, § 32 invalidates the Circuit Court’s preliminary injunction. Article III, § 32, however, pertains to legislative orders for the appropriation of funds.

JUDGMENT OF THE CIRCUIT COURT FOR MONTGOMERY COUNTY AFFIRMED IN PART AND VACATED IN PART; CASE REMANDED TO THAT COURT FOR FURTHER PROCEEDINGS. COSTS TO BE PAID BY APPELLANTS.
Judges WILNER and CATHELL join in the judgment only.
Notes
. Maryland Code (1973, Repl. Vol. 2002), Courts and Judicial Proceedings Article, § 12 — 303(3)(i) provides that a party may appeal from an interlocutory order entered by a circuit court that "[g]rant[s] or dissolves] an injunction, but if the appeal is from an order granting an injunction,” then the order may be appealed "only if the appellant has first filed his answer in the cause[.]”
. A First Amended Complaint filed in the Circuit Court on 21 December 2005 (the day of the scheduled hearing for the request for a preliminary *697 injunction) sought to add several new plaintiffs, including Jhonny Francis Guerrel, Yoharis Francis Tamayo, and Ydalis Francis Tamayo (minors, by their father and next friend, Yohara Tamayo Ruiz), and Eelaaf Zahid and Muhammad Loulak Zahid (minors, by their father and next friend, Muhammad Zahid Iqbal). In its 12 January 2006 memorandum opinion and order granting the preliminary injunction, the Circuit Court stated that, in deciding whether to issue a preliminary injunction, it "viewed the case in light of the facts as set forth in the original Complaint.”
. Maryland Code (1982, Repl.Vol.2005), Health-General Article, § 15-103 outlines the administration of the Medical Assistance Program. All statutory references in this opinion are to the Health-General Article unless otherwise specified.
. Article 24 of the Maryland Declaration of Rights provides "[t]hat no man ought to be taken or imprisoned or disseized of his freehold, liberties or privileges, or outlawed, or exiled, or, in any manner, destroyed, or deprived of his life, liberty or property, but by the judgment of his peers, or by the Law of the land.”
. We have re-written the questions for our consideration for clarity.
. Neither the trial court nor the parties explicated the origin of this apparent opportunity to litigate an administrative appeal of Appellants’ action.
See Furnitureland v. Comptroller,
. We note that it appears that the General Assembly, had it chosen to do so, could have restored funding to the program by adopting a Supplemental Appropriation Bill for that purpose. See Constitution of Maryland, Article III, § 52(8).
. Although the court expressed the view that "alienage is not a suspect class,” it later relied upon
Nyquist v. Mauclet,
. Appellants supplementally contend that Maryland courts recognize that the deference afforded to the State under rational basis analysis is especially appropriate in reviewing equal protection challenges to public welfare programs, citing
United Wire, Metal and Machine Health and Welfare Fund v. State of Maryland Deposit Insurance Fund Corporation,
. We stated in a footnote that "[i]n Maryland, because of the Equal Rights Amendment to the Maryland Constitution (Article 46 of the
*718
Maryland Declaration of Rights), classifications based on gender are suspect and subject to strict scrutiny.
State v. Burning Tree Club, Inc.,
. Legal resident aliens as a group, by sole virtue of their immigration status, are not to be imagined as dole bludgers. Rather, these individuals are contributing members of society in that "[ajliens like citizens pay taxes and may be called into the armed forces.”
Graham,
. Appellants look to
Soskin v. Reinertson,
*720
In
Doe,
the State supreme court found that a Massachusetts statutory provision barring welfare benefits to certain aliens based on the duration of their State residency was not a classification based on alienage because it distinguished between subgroups of aliens.
Doe,
Applying a similar rationale, the U.S. Court of Appeals for the Tenth Circuit, in
Soskin,
determined that "[a] state’s exercise of the option to include fewer aliens in its aliens-only program [under the provisions of PRWORA] ... should not be treated as discrimination against aliens as compared to citizens. Rather, what the State is doing is discriminating within the aliens-only program against one class of aliens as compared to other classes of aliens.”
Soskin,
Rather, Graham and Nyquist make clear that discrimination among sub-classes of resident aliens remains a suspect classification and thus a State's discriminatory action will be subjected to strict judicial scrutiny review.
. The Court stated further that “[d]ivision by a State of the category of persons who are not citizens of that State into subcategories of U.S. citizens and aliens has no apparent justification, whereas, a comparable classification by the Federal Government is a routine and normally legitimate part of its business."
Mathews,
Regarding discrimination in the treatment of aliens by a State, the Court stated that "whereas the Constitution inhibits every State’s power to restrict travel across its own borders, Congress is explicitly empowered to exercise that type of control over travel across the borders of the United States.”
Mathews, 426
U.S. at 85,
"State alien residency requirements that either deny welfare benefits to noncitizens or condition them on longtime residency, equate with the assertion of a right, inconsistent with federal policy, to deny entrance and abode. Since such laws encroach upon exclusive federal power, they are constitutionally impermissible.” Graham v. Richardson,403 U.S. 365 , 380,91 S.Ct. at 1848 ,29 L.Ed.2d at 534 .
Mathews,
. No party in the present action suggests the unconstitutionally of Congress' enactment of PRWORA itself. Thus, we focus our examination on the State's action. In doing so, we nonetheless consider the authority of Congress to authorize the States to, at their discretion, discriminate against aliens in the distribution of State-funded medical assistance benefits.
. We note that there is some basis for limiting the federal government's authority to effectuate national immigration policy to only certain areas, which basis does not include regulating the guidelines used by States when providing solely State-funded medical assistance benefits to aliens. In
Plyler v. Doe,
*726 With respect to the actions of the Federal Government, alienage classifications may be intimately related to the conduct of foreign policy, to the federal prerogative to control access to the United States, and to the plenary federal power to determine who has sufficiently manifested his allegiance to become a citizen of the Nation.
In
Mathews
v.
Diaz,
[t]he decision to share that bounty [welfare benefits] with our guests may take into account the character of the relationship between the alien and this country: Congress may decide that as the alien’s tie grows stronger, so does the strength of his claim to an equal share of that munificence.
Also, in
Graham v. Richardson,
. An example of the divergence among States acting on maintaining coverage of medical assistance benefits for aliens ineligible for federal Medicaid is seen by the treatment in New York's and Maryland’s current coverage.
See Aliessa,
. It matters not to our analysis that Maryland chose to exercise the discretion purportedly accorded by PRWORA in 1996 to continue to extend medical benefits to the relevant sub-class of aliens not covered by federal medical benefits until FY 2006 when it recanted those benefits. The State may not act independently in a discriminatory manner with regard to distributing State-funded medical benefits to lawful resident aliens unless it survives a strict scrutiny standard of review. The purported discretionary authorization of PRWORA does not reduce that standard of review of the State's action.
. The Court of Appeals of New York determined also that the relevant provision of the New York Medicaid statute also violated a separate article of its State constitution, which mandates care for the needy. Maryland does not have a similar article in its State constitution.
. To support its conclusion of requiring uniformity in the federal directive before it will apply relaxed scrutiny to a State action, the Court of Appeals of New York relied upon
Graham, supra,
. Immediately following this analysis, the court stated that
[fit would make no sense to say that Congress has plenary power in the area of immigration and naturalization and then hold that the Constitution impels the states to refrain from adhering to the federal guidelines.
Sudomir v. McMahon,
. In further support of its conclusion, the Ninth Circuit relied on
Monmouth Medical Center v. Hau Kwok,
. The U.S. Court of Appeals for the Tenth Circuit has viewed more narrowly this uniformity requirement for applying a relaxed scrutiny standard. In
Soskin v. Reinertson,
. Additionally, we do not find the reasons provided in PRWORA to justify denying eligibility for federal benefits (promoting self-sufficiency and discouraging illegal aliens) to meet the strict scrutiny standard of review applied to the State’s action in the present case.
. As we stated in
State Department v. Baltimore County,
[I]t is quite clear from our cases that a preliminary injunction will lie when it is necessary to preserve the status quo. Tyler v. Secretary of State,230 Md. 18 , 20,185 A.2d 385 , 386 (1962); Dolan v. Motion Picture Etc. Union,206 Md. 256 , 258-260,111 A.2d 462 , 463 (1955) (in suit to enjoin union from expelling plaintiffs, alleging threat of loss of jobs and other property rights, chancellor should have issued a preliminary injunction pending a decision on his own jurisdiction in order to preserve status quo); Kahl v. Con. Gas, El. Lt. & Power Co.,189 Md. 655 , 658,57 A.2d 331 , 332-33 (1948) (no abuse in refusing preliminary injunction in view of defendant's stipulation and agreement to maintain the status quo); Martin v. United States Wkrs. Ass’n,189 Md. 383 , 388,56 A.2d 28 , 30 (1947) (order refusing to dissolve injunction reversed for lack of indispensable party; effect of injunction was to change the status quo by assisting the plaintiff to gain possession of assets belonging not to defendants but to a party not before the court); 43 C.J.S. Injunctions § 2, at 406 (1945) (sole object of preliminary injunction is to preserve subject in controversy in its then existing condition and to prevent any act whereby right in controversy may be materially injured or endangered).
