Plaintiff Jerry Charles, a Muslim inmate, filed an action against officials with the Wisconsin Department of Corrections’ Division of Adult Institutions (collectively, “DOC”), alleging separate violations of his First Amendment right to the free exercise of religion as well as the Religious Land Use and Institutionalized Persons Act (“RLUIPA”), 42 U.S.C. § 2000cc-l(a), because DOC officials prohibited him from possessing Islamic prayer oil in his cell and from celebrating more than one religious feast per year. The district court granted summary judgment in favor of the DOC on both of Charles’ First Amendment claims and on his religious feast claim under RLUIPA.
The court, however, held that the DOC violated RLUIPA by refusing to allow Charles to possess a reasonable quantity of prayer oil but reserved judgment on the DOC’s constitutional challenge to RLUIPA *605 in order to allow the United States to intervene and defend the statute. Following intervention by the United States, the district court held that RLUIPA was a constitutional exercise of Congress’ power under the Spending Clause and that it did not violate the Tenth Amendment or the First Amendment’s Establishment Clause. As a result, the court entered summary judgment in favor of Charles on his prayer oil claim under RLUIPA. We affirm.
BACKGROUND
Charles is a practicing Muslim inmate at the Oshkosh Correctional Institute, a medium-security prison operated by the DOC. According to Muslim practices, Charles prays five times a day and undergoes ritual cleansing or purification, in part to eliminate offensive body odors pri- or to prayer. 1 This ritual cleansing often involves the application of fragrant prayer oil. In April 2001, the DOC implemented two, revised Internal Management Procedures (“IMPs”), # 6 and # 6A. 2 These IMPs addressed “Religious Beliefs and Practices” and “Religious Property,” respectively.
IMP # 6 identified seven “umbrella religion groups” (including Protestant, Muslim, Native American, Catholic, Jewish, Buddhist, and Wiccan) and established procedures and guidelines for each group. IMP # 6A addressed the quantity and type of religious property that each inmate could possess in DOC institutions and listed specific, approved items for each umbrella religion group. Inmates purchase religious and other personal property with personal funds, managed by the correctional institution in which the inmate is being held. IMP # 6A lists religious books and publications, prayer beads, a prayer rug, and a kufi cap as approved items for Muslim inmates but does not list Islamic prayer oil. DOC officials, therefore, prohibited Charles from possessing any such oil, though other kinds of fragrant body oils and lotions were made available to inmates.
The DOC received approximately 14.5 million federal dollars in fiscal year 2001, which comprised roughly 1.6% of DOC’s annual budget, none of which was directed to religious programs. Each time an inmate seeks to purchase a personal property item, the DOC must follow extensive bureaucratic procedures. These procedures are designed to ensure that the requested item is permissible; not a security threat; properly ordered, received, and inventoried by various prison officials; and delivered undamaged to the inmate upon receipt at the correctional institution or following an inmate’s transfer between DOC facilities. According to the DOC, in developing IMP # 6A, DOC officials consulted and conducted research with religious leaders in order to identify specific, allowable religious property and to create fairness among religious faiths.
Congress enacted RLUIPA following the Supreme Court’s decision in
City of Boerne v. Flores,
No government shall impose a substantial burden on the religious exercise of a person residing in or confined to an institution, as defined in section 1997 of this title, even if the burden results from a rule of general applicability, unless the government demonstrates that imposition of the burden on that person—
(1) is in furtherance of a compelling governmental interest; and
(2) is the least restrictive means of furthering that compelling governmental interest.
42 U.S.C. § 2000cc-l(a) (2000).
Rather than rely on the Fourteenth Amendment, Congress invoked the Spending and Commerce Clauses and hinged the applicability of RLUIPA on whether: “(1) the substantial burden is imposed in a program or activity that receives Federal financial assistance; or (2) the substantial burden affects, or removal of that substantial burden would affect, commerce with foreign nations, among the several States, or with Indian tribes.” 42 U.S.C. § 2000cc-1(b). If the sole basis for the applicability of RLUIPA rests in the Commerce Clause power, a defendant can assert an affirmative defense that RLUIPA is inapplicable if the burden at issue “would not lead in the aggregate to a substantial effect on interstate commerce.” 42 U.S.C. § 2000cc-2(g). Finally, RLUI-PA creates a private right of action for individual prisoners and grants the United States power to enforce the statute through injunctive or declaratory relief. 42 U.S.C. § 2000cc-2(a), (f).
ANALYSIS
We undertake a de novo review of the district court’s grant of summary judgment in favor of Charles, because the parties do not dispute any material facts and present only questions of law for our consideration.
O’Kane v. Apfel,
A. Spending Clause Authority
As a starting point, we note that the parties do not dispute that if RLUIPA is constitutional it would apply in this case because the DOC receives federal funding. 42 U.S.C. § 2000ec-1(b). The United States Constitution gives Congress the power to “lay and collect Taxes, Duties, Imposts, and Excises, to pay the Debts and provide for the Common Defence and general Welfare of the United States.” U.S. Const. art. I, § 8, cl. 1. The Supreme Court has held that Congress may attach conditions to the receipt of federal money incident to its Spending Clause power.
South Dakota v. Dole,
First, under the plain language of the Constitution, use of the Spending power must be in pursuit of “the general Welfare.” U.S. Const. art. I, § 8, cl. 1;
Dole,
1. Pursuit of the general welfare
The Court of Appeals for the Ninth Circuit recently held that RLUIPA satisfies the first part of the
Dole
test in that Congress’ attempt to protect prisoners’ religious rights is in line with the protections afforded by the Constitution through the First Amendment’s Free Exercise Clause.
Mayweathers v. Newland,
2. Unambiguous conditions
The second part of the
Dole
test requires that Congress make unambiguous the presence of any conditions attached to the receipt of federal funds.
Dole,
Congress is not required to list every factual instance in which a state will fail to comply with a condition. Such specificity would prove too onerous, and perhaps, impossible. Congress must, however, make the existence of the condition itself — in exchange for the receipt of federal funds — explicitly obvious.
Mayweathers,
The DOC argues that RLUIPA’s conditions are ambiguous because the statute employs a “least restrictive means” test. According to the DOC, Pennhurst stands for the proposition that the least restrictive means test is too indefinite a standard under which to impose conditions upon the receipt of federal funding. In other *608 words, there is too much guesswork involved.
The DOC’s reading of
Pennhurst,
however, is not one we are willing to adopt. At issue in
Pennhurst
was whether the Developmental^ Disabled Assistance and Bill of Rights Act of 1975, 42 U.S.C. § 6000
et seq.,
had as a condition of accepting federal funding the requirement that States provide “appropriate treatment” to disabled residents in the “least restrictive environment.”
Pennhurst,
As for RLUIPA, we find that Congress clearly and unambiguously attached conditions to the acceptance of federal funding for prisons, and that the State of Wisconsin, particularly the DOC, was put on notice of those conditions. As the Mayweathers court noted, Congress cannot delineate every instance in which a State may or may not comply with the least restrictive means test; it is simply impossible to do. There are far too many circumstances affecting the States in different ways for Congress to have envisioned all aspects of compliance and noncompliance. Rather, Congress permissibly conditioned the receipt of federal money in such a way that each State is made aware of the condition and is simultaneously given the freedom to tailor compliance according to its particular pe-nological interests and circumstances. If the DOC objected to the imposition of the least restrictive means test, it certainly could have refused federal funding.
3. Conditions must be related to a federal interest
The
Dole
Court’s third requirement is that any conditions attached to federal funding be related to a federal interest.
New York v. United States,
The DOC argues that the conditions imposed by RLUIPA cannot be related to a federal interest because the DOC
*609
does not allocate any of its federal funding specifically to religious programs in prisons and because federal funds comprise roughly 1.6% of the DOC’s annual budget. Those arguments are misplaced. First, the Supreme Court’s decision in
Dole
upheld the conditioning of federal highway funding upon a State establishing a minimum drinking age.
Dole,
4. Independent Constitutional bar
The final part of the
Dole
test recognizes that “other constitutional provisions may provide an independent bar to the conditional grant of federal funds.”
Dole,
Similarly, when Congress engages in a constitutional use of its delegated Article I powers, the Tenth Amendment does not reserve that power to the States. U.S. Const. amend. X;
New York,
B. Establishment Clause Violation
The Establishment Clause provides that, “Congress shall make no law respecting an establishment of religion.” U.S. Const. amend. I. The Supreme Court developed a three-part test in order to discern whether Congress has violated the Clause: “First, the statute must have a secular legislative purpose; second, its principal or primary effect must be one that neither advances nor inhibits religion; finally, the statute must not foster ‘an excessive government entanglement with religion.’ ”
Lemon v. Kurtzman,
The Supreme Court has stated, however, that “the government may (and sometimes must) accommodate religious practices and that it may do so without violating the Establishment Clause.”
Corp. of Presiding Bishop of the Church of Jesus Christ of Latter-Day Saints v. Amos,
The DOC argues that RLUIPA creates rights in favor of religious inmates while excluding non-religious inmates and ignoring the State’s right to administer its correctional system as it sees fit. When the “government acts with the proper purpose of lifting a regulation that burdens the exercise of religion, we see no reason to require that the exemption comes packaged with benefits to secular entities.”
Amos,
does not violate the Establishment Clause just because it seeks to lift burdens on religious worship in institutions without affording corresponding protection to secular activities or to non-religious prisoners. RLUIPA merely accommodates and protects the free exercise of religion, which the Constitution allows.
Mayweathers,
Finally, a provision of RFRA nearly identical to the one at issue in RLUIPA has been held constitutional under the Establishment Clause by this Circuit and several others.
In re Young,
The requirements of RLUIPA cannot fairly be said to amount to government advancement of religion through the government’s own activities or influence. RLUIPA seeks to remove only the most substantial burdens States impose upon prisoners’ religious rights, while giving States’ penological interests due consideration. The statute does not promote religious indoctrination, nor does it guarantee prisoners unfettered religious rights, and not every challenge under RLUIPA will be deemed valid. 4
Because the enactment of RLUIPA does not exalt belief over nonbelief, the statute also does not create rights for religious inmates that do not exist for non-religious inmates. The DOC argues that RLUIPA is problematic because its “accommodation” of religious property somehow increases the overall quantity of personal property that inmates are entitled to possess. RLUIPA, however, does not unnecessarily extend the limit the DOC imposes on the amount of religious property an inmate can possess in his cell. We see nothing in the statute’s provisions prohibiting the DOC from requiring the removal of a non-religious item should an inmate wish to possess a religious item to which RLUI-PA entitles him. And, we sincerely doubt that courts will increase exponentially the amount of religious property to which inmates are entitled by virtue of RLUIPA’s protections (thereby mandating the State to allow prisoners to exceed any limit on personal property) in light of States’ interests in maintaining order and security. It happens in this case, however, that the DOC appeals only the district court’s determination as to the constitutionality of RLUIPA, ignoring how the court resolved the merits of Charles’ claim for prayer oil.
Accordingly, we find that Congress did not violate the Establishment Clause of the First Amendment by its enactment of RLUIPA. There being no independent constitutional bar to the statute, it remains a valid exercise of Congress’ Spending Clause authority, and the district court’s decision to award summary judgment in favor of Charles on his prayer oil claim under RLUIPA is AFFIRMED.
Notes
. Apart from its religious implications, this strikes us as a good thing for all involved in the prison setting — or indeed, anywhere else.
. The DOC claims that severe overcrowding and a quadrupling of the State’s prison population over the last twenty years, forcing approximately 4,000 inmates to be placed in out-of-state contract bed facilities, contributes to the difficulties of prison management and necessitates streamlined procedures for handling things such as inmates' personal property. Hence, the DOC revised IMPs # 6 and #6A.
. We further note, though no party mentioned this fact, that the DOC admitted to sending approximately 4,000 of its inmates to out-of-state facilities because of overcrowding. The DOC does not contend, nor would we expect, that IMPs # 6 and # 6A do not apply to these inmates simply because they are housed out of the state. That fact, in our view, lends validity to RLUIPA’s constitutionality under the Commerce Clause in this case. The DOC certainly engages in interstate commerce to properly handle the requests for religious and other personal property from inmates housed outside Wisconsin.
. In fact, Charles’ claim that the DOC violated RLUIPA by allowing him to celebrate only one religious feast per year was rejected by the district court because the court found that, although the restriction created a substantial burden to Charles’ religious rights, allowing only one feast for each "umbrella religion group” was the least restrictive means of furthering the compelling interest for prison order and security; a decision Charles does not appeal to this Court.
