The Tribal Council of respondent Navajo Tribe enacted ordinances
imposing taxes on the value of leasehold interests in tribal lands
and on receipts from the sale of property produced or extracted or
the sale of services within those lands. Petitioner, a mineral
lessee on the Navajo Reservation, brought an action in Federal
District Court, claiming that the taxes were invalid without
approval of the Secretary of the Interior (Secretary). The District
Court agreed, and enjoined the Tribe from enforcing the tax laws
against petitioner. The Court of Appeals reversed, holding that no
federal statute or principle of law mandated approval by the
Secretary.
Held: The Secretary's approval of the taxes in question
is not required. Pp.
471 U. S.
198-201.
(a) While § 16 of the Indian Reorganization Act of 1934
requires a tribal constitution written under the Act to be approved
by the Secretary, the Act does not require the constitution to
condition the power to tax on the Secretary's approval. In any
event, the Act does not govern tribes, like the Navajo, that
declined to accept its provisions. And there is nothing to indicate
that Congress intended to recognize as legitimate only those tribal
taxes authorized by constitutions written under the Act. Pp.
471 U. S.
198-199.
(b) Nor does the Indian Mineral Leasing Act of 1938 require the
Secretary's approval of the Navajo taxes. While § 4 of the Act
subjects mineral leases issued under the Act to regulations
promulgated by the Secretary, the regulations have not required
that tribal taxes on mineral production be submitted for his
approval. In enacting § 4, Congress could properly make a
distinction between a tribe acting as a commercial partner in
selling the right to use its land for mineral production and acting
as a sovereign in imposing taxes on activities within its
jurisdiction. And even assuming that the Secretary could review
tribal taxes on mineral production, it does not follow that he must
do so. Pp.
471 U. S.
199-200.
(c) Nor do statutes requiring the Secretary's supervision in
other contexts indicate that Congress has limited the Navajo Tribal
Council's authority to tax non-Indians. The power to tax members
and non-members
Page 471 U. S. 196
of a tribe alike is an essential attribute of the tribal
self-government that the Federal Government is committed to
promote. Pp.

200-201.
731 F.2d 597, affirmed.
BURGER, C.J., delivered the opinion of the Court, in which all
Members joined, except POWELL, J., who took no part in the
consideration or decision of the case.
CHIEF JUSTICE BURGER delivered the opinion of the Court.
We granted certiorari to decide whether the Navajo Tribe of
Indians may tax business activities conducted on its land without
first obtaining the approval of the Secretary of the Interior.
I
In 1978, the Navajo Tribal Council, the governing body of the
Navajo Tribe of Indians, enacted two ordinances imposing
Page 471 U. S. 197
taxes known as the Possessory Interest Tax and the Business
Activity Tax. The Possessory Interest Tax is measured by the value
of leasehold interests in tribal lands; the tax rate is 3% of the
value of those interests. The Business Activity Tax is assessed on
receipts from the sale of property produced or extracted within the
Navajo Nation, and from the sale of services within the nation; a
tax rate of 5% is applied after subtracting a standard deduction
and specified expenses. The tax laws apply to both Navajo and
non-Indian businesses, with dissatisfied taxpayers enjoying the
right of appeal to the Navajo Tax Commission and the Navajo Court
of Appeals.
The Navajo Tribe, uncertain whether federal approval was
required, submitted the two tax laws to the Bureau of Indian
Affairs of the Department of the Interior. The Bureau informed the
Tribe that no federal statute or regulation required the Department
of the Interior to approve or disapprove the taxes.
Before any taxes were collected, petitioner, a substantial
mineral lessee on the Navajo Reservation, brought this action
seeking to invalidate the taxes. Petitioner claimed in the United
States District Court for the District of Arizona that the Navajo
taxes were invalid without approval of the Secretary of the
Interior. The District Court agreed, and permanently enjoined the
Tribe from enforcing its tax laws against petitioner.
The United States Court of Appeals for the Ninth Circuit
reversed. 731 F.2d 597 (1984). Relying on
Southland Royalty Co.
v. Navajo Tribe of Indians, 715 F.2d 486 (CA10 1983), it held
that no federal statute or principle of law mandated Secretarial
approval. [
Footnote 1]
We granted certiorari. 469 U.S. 879 (1984). We affirm.

In
Merrion v. Jicarilla Apache Tribe, 455 U.
S. 130 (1982), we held that the
"power to tax is an essential attribute of Indian sovereignty
because it is a necessary instrument of self-government and
territorial management."
Id. at
455 U. S. 137.
Congress, of course, may erect "checkpoints that must be cleared
before a tribal tax can take effect."
Id. at
455 U. S. 155.
The issue in this case is whether Congress has enacted legislation
requiring Secretarial approval of Navajo tax laws.
Petitioner suggests that the Indian Reorganization Act of 1934
(IRA or Act), 48 Stat. 984, 25 U.S.C. § 461
et seq.,
is such a law. Section 16 of the IRA authorizes any tribe on a
reservation to adopt a constitution and bylaws, subject to the
approval of the Secretary of the Interior. 25 U.S.C. § 476.
The Act, however, does not provide that a tribal constitution must
condition the power to tax on Secretarial approval. Indeed, the
terms of the IRA do not govern tribes, like the Navajo, which
declined to accept its provisions. 25 U.S.C. § 478.
Many tribal constitutions written under the IRA in the 1930's
called for Secretarial approval of tax laws affecting non-Indians.
See, e.g., Constitution and Bylaws of the Rosebud Sioux
Tribe of South Dakota, Art. 4, § 1(h) (1935). But there were
exceptions to this practice. For example, the 1937 Constitution and
By-laws of the Saginaw Chippewa Indian Tribe of Michigan authorized
the Tribal Council, without Secretarial approval, to "create and
maintain a tribal council fund by . . . levying taxes or
assessments against members or nonmembers." Art. 6, §
1(
g). Thus, the most that can be said about this period of
constitution writing is that the Bureau of Indian Affairs, in
assisting the drafting of tribal constitutions, had a policy of
including provisions for Secretarial approval; but that policy was
not mandated by Congress.
Nor do we agree that Congress intended to recognize as
legitimate only those tribal taxes authorized by constitutions
Page 471 U. S. 199
written under the IRA. [
Footnote
2] Long before the IRA was enacted, the Senate Judiciary
Committee acknowledged the validity of a tax imposed by the
Chickasaw Nation on non-Indians.
See S.Rep. No. 698, 45th
Cong., 3d Sess., 1-2 (1879). And in 1934, the Solicitor of the
Department of the Interior published a formal opinion stating that
a tribe possesses "the power of taxation [which] may be exercised
over members of the tribe and over nonmembers."
Powers of
Indian Tribes, 55 I.D. 14, 46. The 73d Congress, in passing
the IRA to advance tribal self-government,
see Williams v.
Lee, 358 U. S. 217,
358 U. S. 220
(1959), did nothing to limit the established, preexisting power of
the Navajos to levy taxes.
Some tribes that adopted constitutions in the early years of the
IRA may be dependent on the Government in a way that the Navajos
are not. However, such tribes are free, with the backing of the
Interior Department, to amend their constitutions to remove the
requirement of Secretarial approval.
See, e.g., Revised
Constitution and Bylaws of the Mississippi Band of Choctaw Indians,
Art. 8, § 1(r) (1975).
Petitioner also argues that the Indian Mineral Leasing Act of
1938, 52 Stat. 347, 25 U.S.C. § 396a
et seq.,
requires Secretarial approval of Navajo tax laws. Sections 1
through 3 of the 1938 Act establish procedures for leasing oil and
gas interests on tribal lands. And § 4 provides that
"[a]ll operations under any oil, gas, or other mineral lease
issued pursuant to the [Act] shall be subject to the rules and
regulations promulgated by the Secretary of the Interior."
25 U.S.C. § 396d. Under this grant of authority, the
Secretary has issued comprehensive regulations governing the
operation of oil and gas leases.
See 25 CFR pt. 211
(1984). The Secretary, however, does not demand that
Page 471 U. S. 200
tribal laws taxing mineral production be submitted for his
approval.
Petitioner contends that the Secretary's decision not to review
such tax laws is inconsistent with the statute. In
Merrion, we emphasized the difference between a tribe's
"role as commercial partner," and its "role as sovereign." 455 U.S.
at
455 U. S.
145-146. The tribe acts as a commercial partner when it
agrees to sell the right to the use of its land for mineral
production, but the tribe acts as a sovereign when it imposes a tax
on economic activities within its jurisdiction.
Id. at
455 U. S. 146;
cf. White v. Massachusetts Council of Construction Employers,
Inc., 460 U. S. 204,
460 U. S.
206-208 (1983). Plainly Congress, in passing § 4 of
the 1938 Act, could make this same distinction.
Even assuming that the Secretary could review tribal laws taxing
mineral production, it does not follow that he must do so. We are
not inclined to impose upon the Secretary a duty that he has
determined is not needed to satisfy the 1938 Act's basic purpose --
to maximize tribal revenues from reservation lands.
See
S.Rep. No. 985, 75th Cong., 1st Sess., 2-3 (1937). Thus, in light
of our obligation to "tread lightly in the absence of clear
indications of legislative intent,"
Santa Clara Pueblo v.
Martinez, 436 U. S. 49,
436 U. S. 60
(1978), we will not interpret a grant of authority to regulate
leasing operations as a command to the Secretary to review every
tribal tax relating to mineral production. [
Footnote 3]
Finally, we do not believe that statutes requiring Secretarial
supervision in other contexts,
see, e.g., 25 U.S.C.
§§ 81, 311-321, reveal that Congress has limited the
Navajo Tribal Council's authority to tax non-Indians. As we noted
in
New Mexico v. Mescalero Apache Tribe, 462 U.
S. 324 (1983), the Federal Government is "firmly
committed to the
Page 471 U. S. 201
goal of promoting tribal self-government."
Id. at
462 U. S.
334-335;
see, e.g., Indian Financing Act of
1974, 88 Stat. 77, 25 U.S.C. § 1451
et seq. The power
to tax members and non-Indians alike is surely an essential
attribute of such self-government; the Navajos can gain
independence from the Federal Government only by financing their
own police force, schools, and social programs.
See
President's Statement on Indian Policy, 19 Weekly Comp.Pres.Doc.
98, 99 (Jan. 24, 1983).
III
The Navajo Government has been called "probably the most
elaborate" among tribes. H.R.Rep. No. 78, 91st Cong., 1st Sess., 8
(1969). The legitimacy of the Navajo Tribal Council, the freely
elected governing body of the Navajos, is beyond question.
[
Footnote 4]
See,
e.g., 25 U.S.C. §§ 635(b), 637, 638. We agree with
the Court of Appeals that neither Congress nor the Navajos have
found it necessary to subject the Tribal Council's tax laws to
review by the Secretary of the Interior; accordingly, the judgment
is
Affirmed.
JUSTICE POWELL took no part in the consideration or decision of
this case.
[
Footnote 1]
The Ninth Circuit rejected petitioner's other contentions, which
included Commerce Clause and contractual challenges to the two
taxes. Petitioner has not sought review of this aspect of the Court
of Appeals' judgment.
[
Footnote 2]
For example, in
Washington v. Confederated Tribes of
Colville Indian Reservation, 447 U. S. 134,
447 U. S.
152-154 (1980), we sustained taxes imposed on nonmembers
by the Colville and Lummi Tribes even though the Tribes were not
organized under the IRA.
[
Footnote 3]
Section 2 of the 1938 Act provides a limited exemption for
tribes organized under the IRA. 25 U.S.C. § 396b. Because we
conclude that the 1938 Act does not require the Secretary to review
tribal taxes, however, the Navajo Tribe's decision not to accept
the IRA is irrelevant.
[
Footnote 4]
The Tribal Council has 88 members who are elected every four
years. There are approximately 79,000 registered tribal voters, and
69% of these persons voted in the last tribal election in 1982.
