personal property for purposes of ad valorem tax assessment under the Equal Protection Clause of

State Constitution. The district court found that the Tax Injunction Act, 28 U.S.C. § 1341, and
comity principles bar Colonial from suing in federal court. For the following reasons, we AFFIRM
the district court’s decision.
                                                 BACKGROUND
         Colonial is a corporation “engaged in interstate commerce as a common carrier of refined
petroleum products and operates a large diameter refined petroleum pipeline extending from
Pasadena, Texas, to Linden, New Jersey (New York Harbor), with stub lines serving parts of
Tennessee.” (J.A. 26) Colonial’s pipeline “is the largest refined petroleum products pipeline in the
world,” (J.A. 30), and serves as a “transportation system for . . . heating oil, diesel fuel, kerosene,
jet fuel and gasoline.” (J.A. 29) Colonial has operated the pipeline in Tennessee for more than forty
years.
        Under Tennessee Code Annotated (“T.C.A.”) § 67-5-501(8)(G), “Colonial’s real and
personal property is classified and assessed as public utility property.” (J.A. 30) Under T.C.A.
§ 67-5-1301(a)(7), Colonial’s property “is appraised and assessed by the Comptroller of the
Treasury, Office of State Assessed Properties” (“OSAP”). (J.A. 30) OSAP appraises Colonial’s
property as a single unit pursuant to T.C.A. § 67-5-1302. “The unit value of Colonial, which
traverses thirteen states, is apportioned to Tennessee by a recognized apportionment formula.” (J.A.
30; see T.C.A. §§ 67-5-1322 and 67-5-1323) “OSAP then applies the public utility assessment
percentage of 55% to Tennessee’s share of Colonial’s unit value.” (J.A. 30)
       The record indicates that in the 1990s, airlines and railroads sued the Tennessee State Board
of Equalization (“the Board” or “the State Board”) “seeking ad valorem tax relief in the form of
equalization of ad valorem taxes.” (J.A. 31-32) Prior to this legal action, “all public utility
operating property in Tennessee was assessed at 55% of its equalized value, whether real property
or person property.” (J.A. 32) On September 30, 1997, the lawsuit resulted in “a new form of
equalization adjustment factor to the personal property portion” of public utility property. (J.A. 33;
137)
         The classification of Colonial’s property as either real or personal property before
September 30, 1997 is not legally significant because both the real and personal property of public
utility companies was assessed and taxed at the same rate prior to the equalization adjustment. (J.A.
137; Def. Br. at 6) “On October 9, 1997, Colonial applied to the State Board to classify Colonial’s
operating pipeline property in Tennessee as personal property.” (J.A. 33) “Subsequently, OSAP
recommended to the State Board that substantially all of Colonial’s operating pipeline property be
classified as real property, thereby substantially depriving Colonial of the equalization relief
afforded to personal property by the State Board’s Order of September 30, 1997.” (J.A. 33) The
Board consolidated numerous pipeline classification appeals and on January 25-27, 1999, an
administrative law judge (“ALJ”) conducted a hearing on the appeals. On January 14, 2000, the ALJ
upheld the pipeline classification as real property. On February 14, 2000, Colonial appealed to the
Board. The Board held a hearing on January 31, 2001, and affirmed the ALJ’s decision on March
14, 2001. On May 11, 2001, Colonial appealed the Board’s decision to the Tennessee Court of
Appeals. On December 19, 2002, the Tennessee Court of Appeals reversed the Board’s decision
finding that “the pipelines and surface equipment shall be treated as personal property for purposes
of ad valorem taxation.” ANR Pipeline Co. v. Tenn. Bd. of Equalization, No. M2001-01098-COA-
R12-CV, 2002 WL 31840689, at *4 (Tenn. Ct. App. Dec. 19, 2002) (unpublished case).1 “[O]n

         1
           In an unrelated action, Colonial challenged Maryland’s classification of Colonial’s pipeline as real property.
“[T]he Maryland Court of Appeals held that the pipeline was personal property under the common law.” (J.A. 35; see
Colonial Pipeline Co. v. State Dep’t of Assessments and Taxation, 371 Md. 16, 39 (2002) (“the pipeline system should
be classified as personal property for Maryland property tax purposes.”))
No. 06-5220                  Colonial Pipeline Co. v. Morgan, et al.                                Page 3


February 14, 2003, the State Board filed an Application for Permission to Appeal in the Supreme
Court of Tennessee.” (J.A. 35) The application was denied on June 30, 2003. Pursuant to ANR
Pipeline Co., OSAP classified Colonial’s pipeline as personal property for 2003.
       On May 18, 2004, the Tennessee state legislature enacted a law that “effectively nullifies the
2002 decision of the Tennessee Court of Appeals by amending T.C.A. § 67-5-501(9),” and
“deprive[s] Colonial of the equalization relief afforded to centrally assessed owners of personal
property.” (J.A. 37; see 2004 Tenn. Pub. Acts, ch. 719 (effective May 18, 2004)) In pertinent part,
T.C.A. § 67-5-501(9) was amended as follows:
                For purposes of classification and assessment of property:
                ...
                (9)(B) Real property includes, but is not limited to, the following:
                ...
                (iii) Mains, pipes, pipelines and tanks permitted or authorized to
                be built, laid or placed in, upon, or under any public or private
                street or place for conducting steam, heat, water, oil, electricity
                or any property, substance or product capable of transportation
                or conveyance therein or that is protected thereby, excluding
                propane tanks for residential use and above ground storage tanks
                which can be moved without disassembly and are not affixed to the
                land[.]
T.C.A. § 67-5-501(9) (emphasis added).
          On August 11, 2004, Colonial appealed its 2004 ad valorem property tax assessment. On
August 18, 2004, a hearing was held on Colonial’s appeal. On September 7, 2004, Colonial received
a letter from the Comptroller’s officer stating that: “[t]he exception filed on behalf of the company
. . . raised issues regarding equalization and classification. . . . The issue of classification is a matter
pending litigation.” (J.A. 40) Colonial maintains that the letter indicates that the Board “deems
itself not to be the proper forum for an administrative appeal of the classification issued presented
by” the amendment to T.C.A. § 67-5-501(9). (J.A. 40) Colonial filed an appeal with the Board on
September 14, 2004. Since no hearing was scheduled to address the appeal, Colonial sued numerous
Tennessee state agencies and officials in federal court on February 24, 2005, alleging that it “ha[d]
no plain, adequate, or complete remedy at law to redress the wrongs complained of . . . apart from
the filing of this action.” (J.A. 41)
         In the district court, Colonial argued that the amendment to T.C.A. § 67-5-501(9) deprives
it of equalization of the ad valorem taxation of its personal property, and maintained that the
pipeline classification as real property is arbitrary, capricious, invidiously discriminatory and
without a rational relation to any legitimate government interest in violation of the Equal Protection
Clause of the Fourteenth Amendment and the Tennessee Constitution. Colonial contended that
while motor carriers – namely, airplanes and trucks – are assessed at a forty percent tax rate for real
property and thirty percent for personal property, Colonial’s property is assessed at fifty-five percent
even though it provides and performs similar transportation and delivery services. “Colonial asserts
it is no different from any other transportation company and should be treated the same for property
tax purposes.” (J.A. 190) Colonial alleges that since Tennessee’s definition of real property was
enacted with a discriminatory purpose and results in discriminatory ad valorem taxation, the
classification constitutes discrimination against and an undue burden on interstate commerce in
violation of the Commerce and Supremacy Clauses.
         Colonial sought declaratory and injunctive relief. More specifically, Colonial asked the
district court to 1) declare that Tennessee state statutes governing real property classifications,
No. 06-5220                Colonial Pipeline Co. v. Morgan, et al.                              Page 4


including T.C.A. § 67-5-501(9), are unconstitutional and unenforceable, and 2) enjoin Tennessee
from classifying and assessing Colonial’s property in any way other than as provided in ANR
Pipeline Co., 2002 WL 31840689, at *4.
        On March 17, 2005, Defendants moved to dismiss Colonial’s complaint under Fed. R. Civ.
P. 12(b)(1) for lack of subject matter jurisdiction arguing that the Tax Injunction Act, 28 U.S.C.
§ 1341, and comity principles barred Colonial from suing in federal court. Defendants maintained
that Colonial has a plain, speedy and efficient remedy before the Board and Tennessee state courts.
Contrary to Colonial’s allegation that no hearing was scheduled to address its appeal, Defendants
filed an affidavit from an ALJ assigned to Colonial’s appeal indicating that a status conference was
held on September 28, 2004. Defendants proffered an affidavit from the Comptroller’s office stating
that nothing in the September 7, 2004 letter “was intended to indicate that the Board was unable or
unwilling to entertain Colonial’s appeal of the 2004 assessment.” (J.A. 194)
        For its part, Colonial maintained that “[a]s shown by the taped transcripts of the [legislative]
committee hearings, the individual Defendants, members of the State Board, acting in concert with
members of the Tennessee General Assembly, actively pursued legislative activity during the 2004
legislative session which culminated in the passage and signing of Chapter 719, the contents of
which are in direct conflict with Colonial’s position.” (J.A. 195) Colonial filed a motion under Fed.
R. Civ. P. 12(d) “asking for an opportunity to discover facts that would support its allegations of
federal jurisdiction.” (J.A. 196)
       On November 10, 2005, in a thirty-two page decision, the district court found that:
               the facts presented to the Court, while lengthy, are relatively simple
               and substantially undisputed. The only material factual dispute
               appears to concern the meaning of [the] September 7, 2004 letter.
               Taking the . . . letter and the other facts in the light most favorable to
               Colonial, as the Court would ordinarily do on a motion for summary
               judgment, the Court finds there are no genuine issues of material fact
               that require a preliminary hearing or trial before the Court may rule
               on Defendants’ Motion to Dismiss under Rule 12(b)(1).
(J.A. 200; see Colonial Pipeline Co. v. Morgan, 231 F.R.D. 518, 528 (M.D.Tenn. 2005)) The
district court noted that “[t]he Tennessee Court of Appeals previously demonstrated that it can and
will consider Colonial’s constitutional claims because it ruled in favor of Colonial and other
pipelines in reversing the Board’s property classification decision in 2002.” (J.A. 208) It further
noted that
               Colonial’s last involvement with the state review process took more
               than five years from start to finish, but the undisputed record reflects
               multiple parties were involved in a complex administrative
               proceeding. Colonial began the state review process again in
               September 2004, but has allowed the administrative matter to
               languish while it pursued relief before the Tennessee Tax Study
               Commission, the Tennessee General Assembly, and in this federal
               court. Defendants produced evidence that the matter remains
               pending on the State’s administrative proceeding calendar.
(J.A. 209) The court found that a “taxpayer’s intentional bypass of state remedies is exactly what
the Tax Injunction Act was designed to ward off [,] and the Act bars federal subject matter
jurisdiction where taxpayers pursue federal litigation to avoid paying state taxes or to gain a refund
of state taxes.” (J.A. 202) (alteration in original) (internal quotation marks and citation omitted).
No. 06-5220                Colonial Pipeline Co. v. Morgan, et al.                              Page 5


The district court granted Defendants’ motion to dismiss holding that “as a matter of law . . .
Colonial does have a plain, speedy and efficient remedy and that the Tax Injunction Act bars this
suit.” (J.A. 201)
        On November 28, 2005, Colonial filed a motion for reconsideration. On January 26, 2006,
the district court denied Colonial’s motion. The district court indicated that “the Court assumed in
Colonial’s favor all of the evidence.” (J.A. 58) (emphasis in original). It further indicated that
“[m]ost of the information in [Colonial’s] reply brief [to Defendants’ motion to dismiss] is the same
information Colonial now includes within its Memorandum of Law in Support of Plaintiff’s Motion
to Reconsider and in the hundreds of pages of deposition testimony and exhibits Colonial filed after
this case was closed.” (J.A. 58) “Colonial has not pointed to any intervening change in controlling
law, nor is re-examination of the case necessary to avoid a manifest injustice. The Court carefully
considered all of the parties’ evidence and legal arguments. The Court’s Memorandum and Order
expressly addressed each of the points Colonial now seeks to re-argue in its ‘Motion to Reconsider.’
There is nothing more the Court can add to what it already said.” (J.A. 59) Colonial filed a notice
of appeal on February 2, 2006.
        On appeal, Colonial argues that the district court erred in finding that the Tax Injunction Act
was a bar to federal jurisdiction in the instant case. Colonial maintains that Tennessee cannot
provide Colonial with a fair and impartial administrative review because the Board has “prejudged
the issues, has a pecuniary interest in the outcome of this case, and is not independent of the
[Tennessee] executive branch.” (Colonial’s Br. at 3) In addition, Colonial argues that the Board
does not have authority to address the constitutional challenge raised in the instant case, and
highlights that its prior appeal took over five years to complete. Last, Colonial argues that the public
policy concerns which the Tax Injunction Act was enacted to address are not present in the instant
case.
                                           DISCUSSION
I.     Standard of Review
        This Court reviews de novo the dismissal of a complaint under Fed. R. Civ. P. 12(b)(1) for
lack of subject matter jurisdiction. Am. Landfill, Inc. v. Stark/Tuscarawas/Wayne Joint Solid Waste
Mgmt. Dist., 166 F.3d 835 (6th Cir. 1999). “[E]very federal appellate court has a special obligation
to satisfy itself not only of its own jurisdiction, but also that of the lower courts in a cause under
review.” Greater Detroit Res. Recovery Auth. v. U.S. E.P.A, 916 F.2d 317, 319 (6th Cir. 1990)
(quoting Bender v. Williamsport Area Sch. Dist., 475 U.S. 534, 541 (1986)) (quotation marks
omitted).
II.    The District Court Properly Dismissed Colonial’s Complaint for Lack of Subject
       Matter Jurisdiction
       1.      The Tax Injunction Act
        The district court properly dismissed Colonial’s complaint for lack of subject matter
jurisdiction. The Tax Injunction Act prohibits Colonial from challenging T.C.A. § 67-5-501(9) in
federal court. In pertinent part, the Tax Injunction Act provides:
               [t]he district courts shall not enjoin, suspend or restrain the
               assessment, levy or collection of any tax under State law where a
               plain, speedy and efficient remedy may be had in the courts of such
               State.
No. 06-5220                 Colonial Pipeline Co. v. Morgan, et al.                              Page 6


28 U.S.C. § 1341. The Tax Injunction Act “has its roots in equity practice, in principles of
federalism, and in recognition of the imperative need of a State to administer its own fiscal
operations.” Tully v. Griffin, Inc., 429 U.S. 68, 73 (1976). “A federal district court is under an
equitable duty to refrain from interfering with a State’s collection of its revenue except in cases
where an asserted federal right might otherwise be lost.” Id. at 73; see King v. Sloane, 545 F.2d 7,
8 (6th Cir. 1976) (“The federal courts will not entertain actions for relief from State or local taxes
unless federal rights are protected in no other way.”); see also Mandel v. Hutchinson, 494 F.2d 364,
366 (9th Cir. 1974) (“strong public policy of federal noninterference with state taxation schemes has
been statutorily embodied in 28 U.S.C. § 1341.”). “By express statutory provision, Congress . . .
has directed that federal courts shall not enjoin or restrain the assessment, levy or collection of any
tax under state law where a plain, speedy and efficient remedy may be had in the courts of the
State.” King, 545 F.2d at 8. “The overall purpose of the Tax Injunction Act is consistent with the
view that the ‘plain, speedy and efficient remedy’ exception to the Act’s prohibition was only
designed to require that the state remedy satisfy certain procedural criteria.” Rosewell v. LaSalle Nat.
Bank, 450 U.S. 503, 522 (1981). Since the Tax Injunction Act “limit[s] drastically federal district
court jurisdiction to interfere with so important a local concern as the collection of taxes,” California
v. Grace Brethren Church, 457 U.S. 393, 408 (1982) (quotation marks and citation omitted), a
district court does not have jurisdiction over state and local tax matters where a “plain, speedy and
efficient remedy” is available in state court. 28 U.S.C. § 1341.
        The Supreme Court has interpreted the “plain, speedy and efficient” exception of the Tax
Injunction Act narrowly. See Grace Brethren Church, 457 U.S. at 413 (“we must construe narrowly
the ‘plain, speedy and efficient’ exception to the Tax Injunction Act”). A state remedy is plain,
speedy and efficient if it provides the aggrieved party with a “full hearing and judicial determination
at which [a taxpayer] may raise any and all constitutional objections to the tax,” with ultimate review
available in the United States Supreme Court. Rosewell, 450 U.S. at 514 (quotation marks and
citation omitted); see also Hedgepeth v. Tennessee, 215 F.3d 608, 615 (6th Cir. 2000) (“The state
need only provide a full hearing at which a taxpayer may present and secure a judicial determination
at which he or she may raise any and all constitutional objections to the tax.”). This Court has found
that “[t]he plain, speedy and efficient remedy contemplated by [the Tax Injunction Act] merely
requires that the state provide certain minimal procedural protections against illegal tax collection.”
Hedgepeth, 215 F.3d at 615 (6th Cir. 2000). “State procedures that call for an appeal to a state court
from an administrative decision meet these minimal criteria.” Northwest Airlines, Inc. v. Tenn. State
Bd. of Equalization, 11 F.3d 70, 72 (6th Cir.1993). “The state remedy need not be the best of all
possible remedies.” Alnoa G. Corp. v. City of Houston, Tex., 563 F.2d 769, 772 (5th Cir. 1977).
“[T]he likelihood of plaintiff’s success in the state court is not a factor to be considered when
determining whether the jurisdictional prohibition of § 1341 applies.” Cities Serv. Gas Co. v.
Oklahoma Tax Comm’n, 656 F.2d 584, 586 (10th Cir. 1981). Although delay in reviewing a
taxpayer’s claim may be troubling, Long Island Lighting Co. v. Town of Brookhaven, 889 F.2d 428,
433 (2d Cir. 1989), “[n]owhere in the Tax Injunction Act did Congress suggest that the remedy just
be the speediest.” Rosewell, 450 U.S. at 520.
        2.      Tennessee Provides a Plain, Speedy and Efficient Remedy
        Colonial argues that A) it does not have a state forum for raising its constitutional challenges
to T.C.A. § 67-5-501, and B) Board proceedings are too lengthy to constitute a plain, speedy and
efficient state remedy. Colonial’s arguments are meritless inasmuch as Colonial has a plain, speedy
and efficient state remedy within the meaning of the Tax Injunction Act.
No. 06-5220                Colonial Pipeline Co. v. Morgan, et al.                            Page 7


               A.      Colonial Has A State Forum For Raising Constitutional Claims
        Under Tennessee law, Colonial may challenge OSAP’s property assessment by filing
exceptions with the Board. T.C.A. §§ 67-5-1301(c), 67-5-1327(c) and 67-5-1328(a). Colonial may
raise a broad range of claims before the Board:
               [w]hile the choice of methods for contesting the validity of taxes that
               are assessed pursuant to T.C.A. § 67-5-1301, et seq. is extremely
               limited, once a taxpayer is in the proper forum, a wide variety of
               types of objections may be raised. These include objections based on
               federal and state constitutional provisions, statutes and case law.
Northwest Airlines, Inc. v. Tenn. State Bd. of Equalization, 861 S.W.2d 232, 236 (Tenn.1993); see
also Richardson v. Tenn. Bd. of Dentistry, 913 S.W.2d 446, 456-57 (Tenn.1995). In the instant case,
the Board’s final decision may be appealed to the Tennessee Court of Appeals, and ultimately to the
Tennessee Supreme Court or to the United States Supreme Court if federal constitutional issues are
involved. See T.C.A. § 4-5-322(b)(1(B)(ii).
        Colonial argues that the Board does not have authority to hear its constitutional claims. This
argument is plainly without merit. To the extent that Colonial raises “as applied” constitutional
challenges to T.C.A. § 67-5-501, the Board has authority to hear and decide these claims.
Richardson, 913 S.W.2d at 456-457. Admittedly, the Board is not authorized to hear and decide
“facial” constitutional claims concerning T.C.A. § 67-5-501. Id. However, “facial” constitutional
claims which the Board is not authorized to hear may be submitted to and argued before the
Tennessee Court of Appeals. Id. The Board’s limited authority to decide constitutional issues
“do[es] not establish that the State fails to provide a plain, speedy and efficient remedy for tax
challenges.” Wilson v. Bredesen, 113 F. App’x 70, 73 (6th Cir. 2004) (unpublished case). Since
state courts will be able to address Colonial’s constitutional challenges regardless of whether the
claims may be characterized as “facial” or “as applied” constitutional challenges, Colonial has a
state forum for raising constitutional claims.
               B.      Length of Board Proceedings
         Colonial contends that Board proceedings are too lengthy to constitute a plain, speedy and
efficient state remedy. In support of this contention, Colonial points to its last administrative
proceeding. Admittedly, Colonial’s last administrative proceeding “took more than five years from
start to finish.” (J.A. 209) However, this last “proceeding involved multiple parties and tax years,
months of discovery, a three-day evidentiary hearing before an administrative law judge during
which the parties introduced extensive testimony and exhibits, and subsequent appeals to the State
Board, the [Tennessee] Court of Appeals, and the Tennessee Supreme Court.” (Def. Br. at 25) The
district court found that “the undisputed record reflects multiple parties were involved in a complex
administrative proceeding.” (J.A. 209) The length of the last proceeding does not appear
unreasonable given the complexity of the administrative proceeding.
         Although “Colonial began the state review process again in September 2004,” it “has
allowed the administrative matter to languish while it pursued relief before the Tennessee Tax Study
Commission, the Tennessee General Assembly, and . . . th[e] federal court.” (J.A. 209) In fact, the
district court found that “Defendants produced evidence that the matter remains pending on the
State’s administrative proceeding calendar.” (J.A. 209) Since there is no indication that the Board
No. 06-5220                     Colonial Pipeline Co. v. Morgan, et al.                                          Page 8


proceedings will be excessively delayed,2 the record does not support Colonia’s contention that the
current appeal before the Board – which involves only one party and one tax year – will take long
to resolve.
         Moreover, Colonial’s contention that Tennessee cannot provide a plain, speedy and efficient
remedy is belied by Colonial’s success in the last proceeding. See ANR Pipeline Co., 2002 WL
31840689, at *4. Although the Board ruled against Colonial on the property classification issue in
the last proceeding, the Tennessee Court of Appeals reversed the Board. See id. The amendment
of T.C.A. § 67-5-501 does not establish that the state fails to provide a plain, speedy and efficient
remedy for Colonial’s tax challenges. Since the Tennessee Court of Appeals adequately addressed
Colonial’s concerns in the last proceeding, it is unclear why Colonial now seeks to adjudicate its
claims in federal court.
         3.       The State Board’s Alleged Bias
        Colonial alleges that the State Board A) has asserted a position contrary to its classification
claims, and B) is inherently biased. Colonial’s arguments are meritless.
                  A.        The Board Has Not Asserted a Position Contrary to Colonial’s Claims
        Colonial cites the September 7, 2004 letter from the Comptroller’s office in support of its
contention that the Board has asserted a position contrary to Colonial’s claims. It cites Northwestern
Airlines, Inc. for the proposition that it must bring its tax assessment challenge in federal court
because of the Board’s alleged bias. Admittedly, the Comptroller’s September 7, 2004 letter
references pending litigation. However, the reference to pending litigation appears to have been
erroneous. The record indicates that the Board has not been involved in any litigation in which it
has taken a position in conflict with the classification claims made in Colonial’s complaint.
        In Northwest Airlines, Inc., this Court permitted an assessment challenge in federal court
because the Board was involved in pending litigation in which it had asserted a position that directly
conflicted with the taxpayer’s claim. 11 F.3d at 72-73. In Wilson, this Court recognized that
                  [t]he “peculiar” and “unique” facts of [Northwest Airlines, Inc.]
                  presented “a rare exception” to the jurisdictional bar established by
                  the Tax Injunction Act for one reason. Id. at 71, 73. In that case, the
                  Tennessee Board of Equalization had taken a factual position on the
                  assessment level of personal property in an unrelated case pending in
                  federal court, and the position conflicted with the position of the
                  airlines when they appeared before the Board. Id. at 72-73. In this
                  unusual context, the court held that the Board's concurrent litigation
                  position “preclud[ed] it from properly considering the evidence
                  submitted by the airlines in support of their claims” before the Board.
                  Id. at 73-74.



         2
           In an unrelated case, Colonial presented evidence to support its contention that “Georgia’s ad valorem tax
system is plagued with . . . problems that render it virtually useless for correcting unequal tax assessments.” Colonial
Pipeline Co. v. Collins, 921 F.2d 1237, 1240 (11th Cir. 1991). More specifically, Colonial argued that “only two part-
time hearing officers are available to hear these appeals which has resulted in a backlog of more than 70 appeals,” id.
at 1240, and that Georgia’s “appeals procedure is excessively burdensome because it creates circumstances where a
centrally-assessed taxpayer must pursue simultaneous . . . appeals in each county in which it owns property.” Id. at 1241.
In the instant case, since Colonial has presented no evidence that would suggest systemic delays or backlogs in matters
pending before the Board, Colonial has a viable state remedy.
No. 06-5220                Colonial Pipeline Co. v. Morgan, et al.                            Page 9


Wilson, 113 F. App’x at 74 (citing Northwest Airlines, Inc., 11 F.3d at 71-74). In Northwestern
Airlines, Inc., the Board adopted a position which prevented it from “properly considering the
evidence submitted by [the taxpayers] in support of their claims.” Wilson, 113 F. App’x at 74
(quoting Northwest Airlines, Inc., 11 F.3d at 73-74).
        In the instant case, the Board has not been involved in pending litigation and has not
otherwise asserted a position that directly conflicts with Colonial’s claims. This case is
distinguishable from Northwestern Airlines, Inc., and analogous to Wilson, because no impediment
exists that would preclude the Board from considering Colonial’s classification claims. Like the
taxpayer in Wilson, Colonial cannot circumvent the state remedy by suing in federal court.
               B.      The Board’s Composition
        Colonial maintains that the Board’s composition renders the Board inherently unable to
conduct an impartial administrative appeal. More specifically, it argues that four of the seven
members of the Board are members of the Tennessee government’s executive branch; that three of
the four remaining Board members have executive functions and are elected by the Tennessee
General Assembly; and that five of the seven members have revenue collection responsibilities in
Tennessee. Colonial contends that the Board worked in conjunction with the Comptroller to deny
equalization of ad valorem taxation, and that all Defendants acted jointly and severally and in
cooperation with members of the Tennessee General Assembly in pursuit of common scheme to
amend T.C.A. § 67-5-501(9) and deprive Colonial of equalization of ad valorem taxed. Colonial
alleges that employees and members of the Board and the Comptroller’s office drafted or supported
the legislation that amended T.C.A. § 67-5-501(9).
        For their part, Defendants maintain “that none of the[se] employees . . . are members of the
State Board of Equalization who will be in a position to rule on Colonial’s appeal.” (Def. Br. at 31)
Defendants contend that Board members have no pecuniary interest in the outcome of Colonial’s
constitutional challenge because “the property taxes at issue are county and local taxes, not state
taxes.” (Def. Br. at 34) Defendants argue that “the composition of the State Board, as mandated
by statute, see Tenn. Code Ann. § 4-3-5101 (2005), does not appear to depart in any marked way
from the usual composition of such state boards.” (Def. Br. at 35)
       With respect to this issue, the district court found that
               Colonial has produced no evidence to establish the Board is even
               involved in pending litigation on classification issues of interest to
               Colonial, let alone that the Board has taken a position in such
               litigation contrary to Colonial’s view. While the Board members’
               involvement in the passage of Chapter 719 certainly indicates their
               support of a change in the law, their involvement does not indicate
               any prejudgment of the facts of Colonial’s specific tax case.
(J.A. 207) (emphasis in original) (footnote omitted). The district court properly considered and
rejected Colonial’s bias claims. Indeed, “[a]dministrative decision-makers are presumed to carry
out their duties with honesty and integrity.” Jones v. Greene, 946 S.W.2d 817, 825 (Tenn. Ct. App.
1996); see Doolin Sec. Sav. Bank v. F.D.I.C., 53 F.3d 1395, 1407 (4th Cir. 1995) (“we decline to
abrogate the presumption of honesty and integrity of administrators who serve as adjudicators”).
As the district court stated, “[a]n agency’s support of a public opinion on a policy issue does not
disqualify the agency on the grounds of bias from later acting in its adjudicative role.” (J.A. 206)
It is important to remember that “[e]ven if the Board had taken a position contrary to [the taxpayer]
on this issue, moreover, the Board’s position is a legal one subject to de novo review in state court,
which again would provide her an ample avenue of state relief.” Wilson, 113 F. App’x at 74
No. 06-5220                Colonial Pipeline Co. v. Morgan, et al.                            Page 10


(emphasis in original). Since the Tennessee Court of Appeals will conduct a de novo review of the
Board’s legal conclusion, Colonial’s allegations of bias are unpersuasive. As Colonial’s last appeal
illustrates, the state court may reverse the Board’s decision. Therefore, we decline to accept
Colonial’s bias claims.
       4.      Public Policy Concerns
        Last, Colonial argues that this case does not present any of the public policy concerns which
the Tax Injunction Act was enacted to address. More specifically, Colonial maintains that it has not
withheld the payment of taxes. “The taxes for ad valorem tax year 2004 were paid under protest,
but paid nonetheless.” (J.A. 148) Colonial contends that since the state has not experienced a
revenue interruption, this “case does not involve any of the dangers that the Tax Injunction Act was
enacted to address.” (Colonial’s Br. at 58) Colonial does not cite any case law in support of this
proposition. The Tax Injunction Act “has its roots in equity practice, in principles of federalism, and
in recognition of the imperative need of a State to administer its own fiscal operations.” Tully, 429
U.S. at 73. Comity principles bar Colonial from suing in federal court because
               the state’s interest in administration of its judicial system is important
               . . . [and] federal court interference would be an offense to the state’s
               interest, and . . . such interference would both unduly interfere with
               the legitimate activities of the state and readily be interpreted as
               reflecting negatively upon the state courts’ ability to enforce
               constitutional principles.
Gilbertson v. Albright, 381 F.3d 965, 972 (9th Cir. 2004). Therefore, even if tax payments have not
been withheld, the Tax Injunction Act bars the instant action.
                                           CONCLUSION
       As discussed above, Colonial’s claims are the precise type of claims the Tax Injunction Act
was intended to bar. The district court lacks subject matter jurisdiction because the Tax Injunction
Act, 28 U.S.C. § 1341, and comity principles prohibit the district court from issuing an injunction
enjoining the collection of state taxes. For the foregoing reasons, we AFFIRM the district court’s
decision.
