    Case: 12-14611        Date Filed: 07/01/2013         Page: 2 of 28
    Before WILSON and COX, Circuit Judges, and BOWEN, * District Judge.
    WILSON, Circuit Judge:
    The State of Alabama (State) imposes a 4% sales tax on the gross receipts of
    retail businesses, and a 4% use tax on the storage, use, or consumption of tangible
    personal property. See Ala. Code §§ 40-23-2(1), -61(a).1 Appellant CSX
    Transportation, Inc. (CSX), an interstate rail carrier, pays the 4% sales tax
    whenever it purchases diesel fuel in the State. CSX’s main competitors in the
    State—interstate motor and water carriers—do not. In this appeal, we must decide
    whether exempting CSX’s main competitors from the State’s sales tax is
    discriminatory as to rail carriers in violation of the Railroad Revitalization and
    Regulation Reform Act of 1976 (4-R Act), 49 U.S.C. § 11501(b)(4). We conclude
    that the sales tax is indeed discriminatory and that the State has not offered a
    “sufficient justification” for exempting CSX’s competitors. See CSX Transp., Inc.
    v. Ala. Dep’t of Revenue (CSX II), ––– U.S. –––, 
    131 S. Ct. 1101
    , 1109 n.8 (2011)
    (“Whether the railroad will prevail . . . depends on whether the State offers a
    sufficient justification for declining to provide the exemption at issue to rail
    carriers.”). Accordingly, we reverse.
    *
    Honorable Dudley H. Bowen, Jr., United States District Judge for the Southern District
    of Georgia, sitting by designation.

    For purposes of clarity, both taxes will be referred to as the “sales tax.”

    Case: 12-14611        Date Filed: 07/01/2013         Page: 3 of 28
    I. BACKGROUND
    Rail carriers, motor carriers, and water carriers all compete for the shipment
    of freight in interstate commerce. Although all three purchase diesel fuel toward
    that end, the State taxes each competitor’s purchases differently: water carriers pay
    no tax whatsoever on their diesel fuel purchases, see Ala. Code § 40-23-4(a)(10);
    rail carriers pay the State’s 4% sales tax; and motor carriers pay an excise tax of
    19¢ per gallon, see Alabama Terminal Excise Tax Act (fuel excise tax), 2011 Ala.
    Act 565 (effective October 2012). 2
    The State distributes the revenue from the fuel excise tax as follows: for
    every gallon sold, 13¢ goes to the Alabama Department of Transportation for the
    construction, repair, maintenance, and operation of public roads and bridges, and
    the payment of principal and interest on highway bonds; the remaining 6¢ goes to
    cities and counties for the construction and maintenance of roads and bridges, and
    to the Department of Transportation for general highway purposes. Revenue from
    the sales tax, on the other hand, goes toward a general revenue fund. See Ala.
    Code §§ 40-23-35, 40-23-85.
    2
    During the majority of this litigation, the State codified its fuel excise tax at section 40-
    17-2 of the Alabama Code. In October 2012, the State repealed that section and modified its
    motor fuel tax scheme. See Alabama Terminal Excise Tax Act, 2011 Ala. Act 565 (effective
    October 2012). The new statute changes the timing of the tax’s imposition, but the amount of
    the excise tax (19¢/gallon of diesel fuel) remains the same, and it still exempts motor carriers
    from paying the State’s sales tax on diesel-fuel purchases. For purposes of clarity, both taxes
    will be referred to as the “fuel excise tax.”

    Case: 12-14611     Date Filed: 07/01/2013    Page: 4 of 28
    It is axiomatic that a state has broad discretion in the exercise of its taxing
    power. See Lehnhausen v. Lake Shore Auto Parts Co., 
    410 U.S. 356
    , 359, 
    93 S. Ct. 1001
    , 1003 (1973); Weissinger v. White, 
    733 F.2d 802
    , 805 (11th Cir. 1984).
    That discretion will be reined in, however, where it offends a “specific federal
    right.” Lehnhausen, 410 U.S. at 359, 93 S. Ct. at 1003. At issue here are the
    federal rights Congress has afforded rail carriers pursuant to the 4-R Act. That Act
    provides that a state may not:
    (1) Assess rail transportation property at a value that has a higher ratio
    to the true market value of the rail transportation property than the
    ratio that the assessed value of other commercial and industrial
    property in the same assessment jurisdiction has to the true market
    value of the other commercial and industrial property.
    (2) Levy or collect a tax on an assessment that may not be made under
    paragraph (1) of this subsection.
    (3) Levy or collect an ad valorem property tax on rail transportation
    property at a tax rate that exceeds the tax rate applicable to
    commercial and industrial property in the same assessment
    jurisdiction.
    (4) Impose another tax that discriminates against a rail carrier
    providing transportation subject to the jurisdiction of the Board under
    this part.
    49 U.S.C. § 11501(b) (emphasis added).
    Enacted to “restore the financial stability of the railway system of the United
    States,” the 4-R Act “target[s] state and local taxation schemes that discriminate
    against rail carriers.” CSX II, 131 S. Ct. at 1105 (internal quotation marks
    4
    Case: 12-14611     Date Filed: 07/01/2013     Page: 5 of 28
    omitted). CSX contends that the State’s sales tax discriminates against it in
    violation of § 11501(b)(4) because CSX’s main competitors do not pay the sales
    tax when they purchase diesel fuel, giving them a competitive advantage over
    CSX.
    CSX filed this lawsuit against Alabama’s Department of Revenue and its
    Commissioner in 2008. After the district court dismissed the complaint, we
    affirmed the dismissal based on our precedent in Norfolk Southern Railroad Co. v.
    Alabama Department of Revenue, 
    550 F.3d 1306
    , 1316 (11th Cir. 2008), which
    established the rule that a railroad could not challenge its competitors’ exemptions
    from a sales tax as discriminatory under the 4-R Act. See CSX Transp., Inc. v. Ala.
    Dep’t of Revenue (CSX I), 350 F. App’x 318, 319 (11th Cir. 2009) (per curiam).
    CSX appealed, and the Supreme Court granted certiorari, overruled our decision in
    Norfolk, and held that “CSX may challenge Alabama’s sales and use taxes as
    tax[es] that discriminat[e] against rail carrier[s] under § 11501(b)(4).” CSX II, 131
    S. Ct. at 1114 (alterations in original) (internal quotation marks omitted). The
    Court appeared to impliedly assume that the State’s exemptions for CSX’s
    competitors would be discriminatory unless “the State offers a sufficient
    justification for declining to provide the exemption at issue to rail carriers.” Id. at
    1109 n.8.
    5
    Case: 12-14611     Date Filed: 07/01/2013     Page: 6 of 28
    After we remanded the case back to the district court, the court conducted a
    bench trial and issued an order holding that the State’s sales tax did not
    discriminate against CSX in violation of § 11501(b)(4). See CSX Transp. Inc. v.
    Ala. Dep’t of Revenue (CSX III), 
    892 F. Supp. 2d 1300
    , 1317 (N.D. Ala. 2012).
    The district court reasoned that because the State’s motor carriers paid a roughly
    equivalent amount in taxes pursuant to the State’s fuel excise tax, the motor
    carriers’ exemption from the sales tax was not discriminatory. Id. at 1313 (finding
    that “the tax rate imposed per gallon of diesel fuel for rail carriers and motor
    carriers is essentially the same”). As to the water carriers, the district court held
    that CSX had offered “no evidence regarding the purported discriminatory effect as
    it relates to water carriers.” Id. at 1316. The district court dismissed the matter,
    and this appeal followed.
    II. ANALYSIS
    We review the district court’s application of the 4-R Act de novo, see
    Alphamed, Inc. v. B. Braun Med., Inc., 
    367 F.3d 1280
    , 1285 (11th Cir. 2004),
    taking special heed of the guidance provided by the Supreme Court in CSX II.
    “‘Discrimination,’” the Court wrote, “‘is the failure to treat all persons equally
    when no reasonable distinction can be found between those favored and those not
    favored.’” CSX II, 131 S. Ct. at 1108 (quoting Black’s Law Dictionary 534 (9th
    ed. 2009)). For example, “[t]o charge one group of taxpayers a 2% rate and
    6
    Case: 12-14611     Date Filed: 07/01/2013     Page: 7 of 28
    another group a 4% rate, if the groups are the same in all relevant respects, is to
    discriminate against the latter.” Id. A tax exemption is analogous because the
    “State takes the favored group’s rate down to 0%.” Id. Therefore, CSX II’s
    holding suggests that a tax exemption disfavoring a rail carrier creates a rebuttable
    presumption of discrimination, unless the State can “offer[] a sufficient
    justification for declining to provide the exemption at issue to rail carriers.” Id. at
    1110 n.8.
    A. Comparison Class
    Before we address whether the exemption at issue is discriminatory, there
    remains a first-order question that the Court left untouched and has yet to be
    answered in this circuit: against what do we compare the railroads? The matter is
    one of scope, as any model of discrimination requires a fixed set of participants. If
    we compare CSX to all of the State’s taxpayers, it is no worse off because most
    taxpayers pay the sales tax when they purchase diesel fuel. On the other hand, if
    we compare CSX to motor and water carriers, questions of favorable treatment
    arise because they do not pay the sales tax. Among our sister circuits there are
    essentially two camps: the functional approach and the competitive approach.
    We acknowledge that the question of the proper comparison class has not
    been the central inquiry of this appeal. In the proceedings below, the district court
    and the parties adopted the competitive approach, assuming that CSX must be
    7
    Case: 12-14611    Date Filed: 07/01/2013   Page: 8 of 28
    compared with only motor and water carriers. Although we ultimately conclude
    that the competitive approach is appropriate in this circumstance, we are obliged to
    say a few words concerning the diversity of opinions on this matter.
    Employing the functional approach, the Seventh and Ninth Circuits have
    compared the rail carriers to other “commercial and industrial” taxpayers based on
    § 11501(b)(4)’s three preceding subsections, which all contain the phrase
    “commercial and industrial.” See Kansas City S. Ry. Co. v. Koeller, 
    653 F.3d 496
    ,
    508 (7th Cir.), cert. denied, 
    132 S. Ct. 855
     (2011); Atchison, Topeka & Santa Fe
    Ry. Co. v. Arizona, 
    78 F.3d 438
    , 441 (9th Cir. 1999). For example, in Koeller the
    Seventh Circuit considered whether an Illinois subdivision’s method of calculating
    taxes discriminated against railroads in violation of § 11501(b)(4). Seven hundred
    taxpayers comprised the tax base of the subdivision: eight of the 700 taxpayers
    were railroads, pipelines, and utilities (RPU properties). Koeller, 653 F.3d at 500.
    Of the remaining 692 taxpayers, 14 conducted commercial and industrial
    operations, several were residents, and the vast majority used the land for
    agricultural purposes. Id. After severe floods and an increase in the price of diesel
    fuel sent the subdivision into a budgetary crisis, its commissioners increased the
    annual maintenance assessment—which for all intents and purposes was a “tax.”
    Id. Although the majority of the subdivision’s landowners saw modest hikes in
    their annual assessments, the RPU properties saw “astronomical increase[s].” Id.
    8
    Case: 12-14611      Date Filed: 07/01/2013     Page: 9 of 28
    at 502. Norfolk Southern’s assessment, for instance, jumped a whopping 8,300%
    in one year, from $1,126 to $93,920. Id.
    Before reaching the question of whether the tax was discriminatory, the
    Seventh Circuit acknowledged the different comparison-class options at its
    disposal. The court opted for the functional approach, in part because of “the need
    to read subsection (b)(4) in light of the approach taken in the first three subsections
    of the 4-R Act, which all directly or indirectly look to other commercial and
    industrial property.” Id. at 509 (internal quotation marks omitted). Yet the
    Seventh Circuit also recognized that “there are no competitors of the railroads—
    motor carriers, air carriers, barges, [or] Great Lakes ships—that [the subdivision] is
    trying to tax.” Id. (alteration in original) (emphasis in original) (internal quotation
    marks omitted). Therefore, opting for the competitive approach in Koeller would
    have yielded the bizarre result that a tax singularly raising a rail carrier’s tax rate
    by 4,800% was not discriminatory. With that in mind, the court compared the rail
    carriers with “the 14 additional commercial and industrial taxpayers” who did not
    suffer such a dramatic increase in their tax obligations, and held that the tax was
    discriminatory. Id. at 509–10.
    Contrarily, the Eighth Circuit has endorsed the narrower “competitive
    approach” model, at least when considering a state’s sales tax. See Union Pac.
    R.R. Co. v. Minn. Dep’t of Revenue, 
    507 F.3d 693
    , 695 (8th Cir. 2007); Burlington
    9
    Case: 12-14611     Date Filed: 07/01/2013    Page: 10 of 28
    N., Santa Fe Ry. Co. v. Lohman, 
    193 F.3d 984
    , 986 (8th Cir. 1999) (choosing the
    competitive model, but acknowledging that “the comparison class should be
    appropriate to the type of tax and discrimination challenged in a particular case”
    (emphasis added)). In Lohman, the Eighth Circuit addressed a scenario identical to
    the one before us: whether an exemption to Missouri’s sales tax caused the sales
    tax to violate § 11501(b)(4). See Lohman, 193 F.3d at 984. In that case too, motor
    carriers paid a fuel excise tax rather than a sales tax. Id. at 985. The court
    ultimately held that “the proper comparison class for Missouri sales and use taxes
    is the competitive mode.” Id. at 986. Paying homage to the 4-R Act’s broad
    purpose of restoring the railroads’ financial stability, the court emphasized that
    “[s]tability cannot be restored without making the railroads competitive.” Id.
    Furthermore, the court continued, if Congress “had wanted [§ 11501(b)(4)] to have
    the same comparison class as the property tax subsections, and none other, it would
    have written it that way.” Id.; see also Atchison, 78 F.3d at 445 (Nielsen, J.,
    dissenting) (“If Congress wanted [§ 11501(b)(4)] to share the same broad
    comparison class as the three preceding subsections, and none other, it would have
    said so. It did not.”). This result made sense, the court reasoned, because a broad
    comparison class in that instance would have put the railroads “at a competitive
    disadvantage.” Lohman, 193 F.3d at 986.
    10
    Case: 12-14611        Date Filed: 07/01/2013       Page: 11 of 28
    We have carefully studied the different approaches available to us, and we
    conclude that in light of the 4-R Act’s purpose of ensuring “financial stability” for
    rail carriers, the competitive model best serves that goal in the context of a state’s
    sales tax on diesel fuel. 3 Moreover, CSX and the State stipulated, and the district
    court agreed, that the proper comparison class for this case was CSX’s
    competitors.4 Having determined that the appropriate comparison class is CSX’s
    competitors, we turn to the question of whether the sales tax is discriminatory.
    B. Discrimination
    As noted earlier, the Supreme Court held that tax exemptions can be
    discriminatory under the 4-R Act. CSX II, 131 S. Ct. at 1114. Given that we have
    opted for a competitive model in this case, and CSX’s competitors do not pay the
    State’s sales tax, we hold that CSX has established a prima facie case of
    3
    We therefore decline to adopt Justices Thomas’s dissent in CSX II, which would have
    held that the appropriate comparison class in all 4-R Act discrimination cases is all commercial
    and industrial taxpayers. See CSX II, 131 S. Ct. at 1115 (Thomas, J., dissenting) (“I would hold
    that, to violate § 11501(b)(4), a tax exemption scheme must target or single out railroads by
    comparison to general commercial and industrial taxpayers.”). While this comparison class
    might be appropriate in certain situations, like Koeller, it fails to address discriminatory taxes
    that place rail carriers at a significant disadvantage vis-à-vis their competitors.
    4
    Our approach creates tension with the Seventh Circuit’s holding in Koeller only to the
    extent that Koeller established a bright-line rule for § 11501(b)(4) cases. See Koeller, 653 F.3d
    at 509 (“Given our preference for clarity, however, rather than an ill-defined ‘all the
    circumstances’ type of test, we are content for now to endorse reference to other commercial and
    industrial users.”). While we recognize the virtues of bright-line rules, § 11501(b)(4) is a broad
    statute, designed to strike down all discriminatory taxes that place rail carriers at a competitive
    disadvantage—and Congress “specifically chose to omit any reference to a comparison class in
    subsection [(b)(4)].” Atchison, 78 F.3d at 445 (Nielsen, J., dissenting). Thus, while a malleable
    approach might not lend itself to the most efficient application, the language and purpose of
    § 11501(b)(4) require that “the comparison class should be appropriate to the type of tax and
    discrimination challenged in a particular case.” Lohman, 193 F.3d at 986.
    11
    Case: 12-14611      Date Filed: 07/01/2013    Page: 12 of 28
    discrimination. Quite simply, the sales tax overburdens the rail carriers because its
    competitors do not pay it. It therefore becomes the State’s burden to justify its
    discriminatory tax. See id. at 1110 n.8.
    The State devotes the majority of its brief to defending the motor carriers’
    exemption to the sales tax on the ground that the motor carriers pay a roughly
    equivalent amount of taxes under the fuel excise tax. This argument misses the
    mark. Rather than framing the tax in question at its highest level of abstraction as
    “all the taxes paid on diesel-fuel purchases,” we agree with the Eighth Circuit that
    “we look only at the sales and use tax with respect to fuel to see if discrimination
    has occurred.” Union Pacific, 507 F.3d at 695 (internal quotation marks omitted).
    We are persuaded that even though in some years—depending on the price of
    diesel fuel—the State’s taxing arrangement might yield a fair result, “the actual
    fairness of those arrangements is too difficult and expensive to evaluate.” Lohman,
    193 F.3d at 986 (quoting Trailer Train Co. v. State Tax Comm’n, 
    929 F.3d 1300
    ,
    1303 (8th Cir. 1991)).
    This construction of the 4-R Act finds support in the Act’s text. Section
    11501(b)(4) prohibits the states from “impos[ing] another tax that discriminates
    against a rail carrier,” but the statute hardly “suggests that an individually
    discriminatory tax should be assessed for fairness against the entire tax structure of
    the state.” Kansas City S. Ry. v. McNamara, 
    817 F.2d 368
    , 377 (5th Cir. 1987). If
    12
    Case: 12-14611     Date Filed: 07/01/2013    Page: 13 of 28
    the 4-R Act required us to examine the tax regime for an entire commodity, it
    would have said so rather than speaking in the singular about “another tax.” Like
    the Eighth Circuit in Lohman, we find the Fifth Circuit’s well-reasoned opinion in
    McNamara to speak directly on this issue.
    In McNamara, the Fifth Circuit struck down a Louisiana tax imposed on
    transportation and communication utilities, which included rail carriers. Id. at 370.
    Using a commercial and industrial taxpayer comparison class, the Fifth Circuit
    held that the tax was discriminatory, and that Louisiana could not justify it based
    on the fact that other commercial and industrial taxpayers paid a roughly
    equivalent amount in sales and use taxes. Id. at 377. Refusing to consider the
    sales tax, the Fifth Circuit held that “[d]etermining the intrinsic economic fairness
    of a tax system to a particular taxpayer is a paradigm of the kind of polycentric
    problem for which courts are ill-suited.” Id.
    McNamara provided the rationale for the Eighth Circuit in Lohman and its
    progeny to hold that courts should not evaluate a state’s sales tax against other
    taxes in the state’s code. See Lohman, 193 F.3d at 986. Here, the district court
    below rejected the Eighth Circuit’s reliance on McNamara because McNamara
    employed the functional approach rather than the narrower competitive approach,
    and when the comparison class is thereby “drastically reduced” it does not “impose
    substantial theoretical and practical difficulties on a court.” CSX III, 
    892 F. Supp. 13
    Case: 12-14611         Date Filed: 07/01/2013        Page: 14 of 28
    2d at 1311. Because the comparison class has been narrowed, the dissent assures
    us, federal courts would not engage in “such a searching, time-consuming,
    expensive, and impracticable analysis.” Dissenting Op. at 6. We disagree.
    Although the class of taxpayers might have been narrower had we opted for
    the functional approach, the “theoretical difficult[ies]” that concerned the
    McNamara court would remain. McNamara, 817 F.2d at 377. We would still be
    forced to decide whether a state’s fixed-percentage sales tax for one market
    participant is roughly equivalent to an ad valorem excise tax for another market
    participant. In addition, the authoritative value of that assessment would ebb and
    flow with every oscillation in diesel fuel’s market value—we would operate for
    some months, perhaps even years, under the fiction that the two taxes are
    equivalent.5 Id. (“Furthermore, there is no reason in principle why the railroads
    could not sue for such a judicial assessment each year (or for each tax bill) because
    the dynamic nature of any state’s economy will alter the relative benefits and
    burdens of its tax system from moment to moment.” (emphasis in original)). And
    if the price of diesel fuel causes rail carriers to bear a significantly larger tax
    burden than its competitors, at what point must we reverse course and hold that the
    5
    The dissent also points out that under today’s holding, “the sales and use taxes would
    discriminate against a rail carrier even if its competitors paid four times as much tax as the rail
    carrier for the same commodity.” Dissenting Op. at 7–8. But if we were to adopt the dissent’s
    approach and accept the State’s justification for its discriminatory tax—that motor carriers pay
    some other commodity tax, that is sometimes equivalent—the reverse would also be true. That
    is to say, the sales and use tax exemption would not discriminate against a rail carrier even if its
    competitors paid four times less in tax as the rail carrier for the same commodity.
    14
    Case: 12-14611        Date Filed: 07/01/2013        Page: 15 of 28
    sales tax is discriminatory? After one year of inequity? Three? 6 To adjust the
    comparison class makes little difference, and it behooves us to bear in mind the
    words of the Supreme Court:
    [C]ourts as institutions are poorly equipped to evaluate with precision
    the relative burdens of various methods of taxation. The complexities
    of factual economic proof always present a certain potential for error,
    and courts have little familiarity with the process of evaluating the
    relative economic burden of taxes.
    Minneapolis Star & Tribune Co. v. Minn. Comm’r of Revenue, 
    460 U.S. 575
    , 589–
    90, 
    103 S. Ct. 1365
    , 1374 (1983) (footnote omitted).
    We therefore decline to undertake the Sisyphean burden of evaluating the
    fairness of the State’s overall tax structure in order to determine whether a single
    tax exemption causes a state’s sales tax to be discriminatory. This case, then,
    becomes much simpler than it would appear at first blush. Rail carriers pay the
    State’s sales tax—motor and water carriers do not. It is not a sufficient
    justification for the State to counter that its tax code will ultimately level the
    playing field.
    Even if it were true that the exemptions at issue were not enacted to
    unfavorably target rail carriers, our decision would be the same because
    discrimination under § 11501(b)(4) “can be shown even if there is no direct
    6
    This is to say nothing of the added value that the motor carriers receive from being able
    to accurately forecast their year-to-year tax burden by virtue of being subject to a fixed excise tax
    rather than a variable ad valorem tax.
    15
    Case: 12-14611      Date Filed: 07/01/2013    Page: 16 of 28
    evidence of targeting,” as long as the tax imposes a proportionately heavier burden
    on rail carriers. Koeller, 653 F.3d at 510. Here, the rail carriers’ main competitors
    have received favorable treatment: tax exemptions. In response, the State offers no
    “reasonable distinctions between the favored and the disfavored”; therefore it has
    failed to carry the burden set forth by the Supreme Court in CSX II. Id. In CSX II,
    the Supreme Court queried the State: “Can you justify why motor and water
    carriers are taxed differently than rail carriers?” The State responds: “Motor and
    water carriers are taxed differently because they are taxed differently.” But the
    Supreme Court demanded a justification from the State, not a Zen proverb.
    Section 11501(b)(4) does not allow us to sit idly by and take the State at its word
    that, in the long run, its tax code will burden CSX no more than its competitors.
    Moreover, no one can seriously dispute that the water carriers, who pay not a cent
    of tax on diesel fuel, are the beneficiaries of a discriminatory tax regime.
    III. CONCLUSION
    In short, after establishing a comparison class of competitors and showing
    that its competitors did not pay the sales tax on diesel fuel purchases, CSX made a
    prima facie showing of discrimination under § 11501(b)(4). The burden shifted to
    the State to provide a “sufficient justification” for the exemptions. It did not. We
    reverse the district court, hold that the State’s sales tax violates the 4-R Act, and
    16
    Case: 12-14611     Date Filed: 07/01/2013   Page: 17 of 28
    remand to the district court with instructions to enter declaratory and injunctive
    relief in favor of CSX consistent with this opinion.
    REVERSED AND REMANDED.

    COX, Circuit Judge, dissenting:
    I dissent. Though I agree that the appropriate comparison class consists of
    the stipulated competitors, I do not agree that a tax exemption for interstate motor
    carriers discriminates against interstate rail carriers when motor carriers in fact
    carry a similar or heavier tax burden for purchase of the same commodity. As for
    the tax exemption for interstate water carriers, I conclude that the district court
    improperly placed the burden on CSX to provide evidence of the exemption’s
    discriminatory effect. I would affirm the district court’s ruling to the extent that it
    finds no violation of the 4-R Act with respect to the motor carriers’ exemption but
    remand for reconsideration as to interstate water carriers.
    The Railroad Revitalization and Regulatory Reform Act of 1976 (the 4-R
    Act) prohibits a state taxing authority from taking certain actions that place unfair
    burdens on railroads. The statute’s first three subsections bar a state from making
    unfair assessments on railroad property, collecting a tax on such unfair
    assessments, and collecting an ad valorem property tax at a rate greater than that
    imposed on other “commercial and industrial property,” 49 U.S.C. § 11501(b)(1)–
    (3).1   At issue in this case is § 11501(b)(4), which prohibits a state and its
    1
    Section 11501(b)(1)–(3) reads:
    (b) The following acts unreasonably burden and discriminate against interstate
    commerce, and a State, subdivision of a State, or authority acting for a State or
    subdivision of a State may not do any of them:
    18
    Case: 12-14611        Date Filed: 07/01/2013       Page: 19 of 28
    subdivisions from “[i]mpos[ing] another tax that discriminates against a rail
    carrier.” Id. § 11501(b)(4).
    We use a two-step inquiry to evaluate a claim of discrimination in violation
    of § 11501(b)(4). See CSX Transp., Inc. v. Ala. Dep’t of Revenue, 
    131 S. Ct. 1101
    ,
    1109 n.8 (2011) (CSX II). The plaintiff railroad (CSX here) has the initial burden
    to establish a prima facie case of discriminatory tax treatment. If the plaintiff does
    so, the burden shifts to the defendant taxing authority (the State here) to establish
    that the differential tax treatment is justified and does not discriminate against the
    railroad. Id. (“Whether the railroad will prevail—that is, whether it can prove the
    alleged discrimination—depends on whether the State offers a sufficient
    justification for declining to provide the exemption at issue to rail carriers.”). If
    the defendant cannot meet its burden, the tax treatment violates § 11501(b)(4).
    The parties in this case have agreed that CSX’s competitors are interstate
    motor carriers (“on-highway motor carriers of property in interstate commerce”)
    and interstate water carriers (“carriers of property in interstate commerce by ships,
    (1) Assess rail transportation property at a value that has a higher ratio to
    the true market value of the rail transportation property than the ratio that
    the assessed value of other commercial and industrial property in the same
    assessment jurisdiction has to the true market value of the other
    commercial and industrial property.
    (2) Levy or collect a tax on an assessment that may not be made under
    paragraph (1) of this subsection.
    (3) Levy or collect an ad valorem property tax on rail transportation
    property at a tax rate that exceeds the tax rate applicable to commercial
    and industrial property in the same assessment jurisdiction.

    barges and other vessels”). (Dkt. 63 ¶ 10, at 3.) I proceed through the two-step
    analysis first with respect to motor carriers and then with respect to water carriers.
    A. Motor Carriers
    Like the majority, I have no doubt that CSX has established a prima facie
    § 11501(b)(4) violation by showing that the sales and use taxes apply to rail
    carriers but exempt motor carriers. (Op. at 11–12.) Where I disagree is in the
    second step of the analysis: whether the State has justified the differential
    treatment.
    The State explains the exemption by pointing out that motor carriers must
    pay the 19¢ state excise tax per gallon of fuel they purchase. Rail carriers do not
    pay this tax. According to the State’s argument, the fact that rail carriers are not
    subject to the excise tax justifies the differential treatment in the sales and use
    taxes, and the sales and use taxes do not discriminate against rail carriers.
    The district court agreed with the State. CSX Transp., Inc. v. Ala. Dep’t of
    Revenue, 
    892 F. Supp. 2d 1300
    , 1312–14 (N.D. Ala. 2012) (CSX III). The court
    compared the state sales and use taxes (measured in terms of what rail carriers paid
    per gallon of fuel, including the 4% tax) to the state motor-fuel excise tax
    (measured in terms of what motor carriers paid per gallon, including the 19¢-per-
    gallon tax) assessed from January 2007 to December 2009. Id. at 1313. The court
    found that “motor carriers actually pa[id] a higher” state tax. Id. Even adding to
    20
    Case: 12-14611        Date Filed: 07/01/2013       Page: 21 of 28
    the comparison the additional sales and use taxes imposed on rail carriers by
    counties and cities in Alabama, motor carriers and rail carriers paid “substantially
    similar” taxes during the period in question. Id. 2 And that comparison failed to
    incorporate the motor-fuel excise taxes assessed by counties and cities on motor
    carriers, which ranged from 1¢ to 6¢ added to the state excise tax imposed on
    motor carriers. Id. In sum, the district court found, the taxes paid by rail carriers
    and motor carriers for fuel was “essentially the same.” Id. Because its findings are
    not challenged on appeal, I accept them as accurate.
    None of these findings are relevant, CSX argues, because the State cannot
    justify differential treatment by showing that the entities that are exempt from sales
    and use taxes are subjected to a separate tax not imposed on rail carriers. The
    majority agrees with CSX’s position.                  It refuses to compare the two taxes,
    regardless of the numbers the taxing arrangement yields. (See Op. at 12.) But
    based on my reading of the Supreme Court’s opinion in CSX II and case law in
    other circuits, I find this position both unsupported and contrary to Congress’s
    intent.
    CSX’s argument and the majority opinion follow the approach taken by the
    Eighth Circuit in Union Pacific Railroad Co. v. Minnesota Department of Revenue,
    2
    I assume that sales and use taxes imposed by cities and counties are at issue in this case.
    Given that CSX named no city or county as a defendant, this assumption may not be true; I
    hesitate to agree that a city or county can be enjoined from imposing a tax when it has not been
    named as a party. But even if they can, my conclusion remains the same.
    21
    Case: 12-14611    Date Filed: 07/01/2013   Page: 22 of 28
    
    507 F.3d 693
     (8th Cir. 2007). There, the Eighth Circuit considered Minnesota’s
    generally applicable sales tax on railroad fuel that exempted two primary
    competitors (motor carriers and air carriers) because they paid a separate excise
    tax, see id. at 694—a scenario nearly identical to the one confronting us here.
    Based on its earlier opinion in Burlington Northern, Santa Fe Railway Co. v.
    Lohman, 
    193 F.3d 984
     (8th Cir. 1999), the Eighth Circuit refused to consider any
    other tax as a justification for the facial discrimination. See Union Pac., 507 F.3d
    at 695 (“[W]e ‘look only at the sales and use tax with respect to fuel to see if
    discrimination has occurred.’” (quoting Lohman, 193 F.3d at 986)).
    But as the district court recognized, see CSX III, 892 F. Supp. 2d at 1310–11,
    the Eighth Circuit’s simplistic approach to evaluating challenges under
    § 11501(b)(4) incorrectly relies on distinguishable case law. Lohman, on which
    Union Pacific rests, refuses to consider other taxes as justification for facially
    discriminatory tax treatment. 193 F.3d at 986. The Lohman court relies on two
    cases for the proposition that the fairness of this tax scheme is “too difficult and
    expensive to evaluate,” id.: the Fifth Circuit’s opinion in Kansas City Southern
    Railway Co. v. McNamara, 
    817 F.2d 368
     (5th Cir. 1987), and the Eighth Circuit’s
    own opinion in Trailer Train Co. v. State Tax Commission, 
    929 F.2d 1300
     (8th Cir.
    22
    Case: 12-14611       Date Filed: 07/01/2013      Page: 23 of 28
    1991). 3 But both McNamara and Trailer Train address a materially distinct fact
    pattern, and their analyses are unsuitable for this case.
    In McNamara and Trailer Train, the court considered a different kind of
    tax—a specific tax that “targeted” railroads for differential treatment, 4 rather than a
    general tax that exempted railroads’ competitors. In each case, the court decided
    that the appropriate comparison class consisted of all commercial and industrial
    taxpayers. In each case, the state argued that the tax did not discriminate against
    railroads because the state’s tax structure, as a whole, treated railroads similarly to
    every other commercial and industrial taxpayer. And in each case, the court
    refused to entertain such a searching, time-consuming, expensive, and
    impracticable analysis. See Trailer Train, 929 F.2d at 1302–03; McNamara, 817
    F.2d at 377–78.
    Here, we have a much narrower issue. The appropriate comparison class
    includes the two stipulated competitors—a far more manageable class than one
    composed of all commercial and industrial taxpayers in Alabama. And in arguing
    that a single tax on motor carriers justifies their exemption from another tax, the
    State does not come close to proposing the massive endeavor that Trailer Train
    3
    The majority opinion also applies McNamara and acknowledges Trailer Train. (See
    Op. at 12–14.)
    4
    In McNamara, Louisiana imposed a tax on “public utilities,” a relatively small group of
    taxpayers that included railroads. 817 F.2d at 374. Notably, “public utilities” also included
    certain motor and water carriers. Id. In Trailer Train, Missouri taxed an activity in which only
    railroads engaged. 929 F.2d at 1302.
    23
    Case: 12-14611    Date Filed: 07/01/2013   Page: 24 of 28
    and McNamara refused to undertake. Like the district court, see CSX III, 892 F.
    Supp. 2d at 1310–11, I would distinguish Trailer Train and McNamara on that
    ground, and I would decline to follow Lohman’s and Union Pacific’s lead because
    they rely on those distinguishable cases.
    That we must evaluate the State’s justification, despite the Eighth Circuit’s
    approach, is all the clearer after CSX II.       There, the Court conceded that
    discrimination cases under the 4-R Act will often “raise knotty questions about
    whether and when dissimilar treatment is adequately justified.” CSX II, 131 S. Ct.
    at 1114. But as the Court then insisted, “Congress has directed the federal courts
    to review a railroad’s challenge[,] and . . . we would flout the congressional
    command were we to declare the matter beyond us.” Id.
    Perhaps the most compelling reason to depart from the Eighth Circuit’s
    approach is that, under that approach, we may reach the bizarre holding that a tax
    discriminates against a rail carrier even though the tax puts the rail carrier at no
    discernible disadvantage. The majority opinion reaches just that result, concluding
    that the sales and use taxes discriminate against rail carriers and in favor of motor
    carriers even though motor carriers pay “essentially the same” tax on their fuel.
    (See Op. at 12 (refusing to evaluate the comparison between the two taxes “even
    though in some years . . . the State’s taxing arrangement might yield a fair
    result”).)   Under the majority’s approach, the sales and use taxes would
    24
    Case: 12-14611     Date Filed: 07/01/2013    Page: 25 of 28
    discriminate against a rail carrier even if its competitors paid four times as much
    tax as the rail carrier for the same commodity.
    I cannot agree with that approach. Congress created the 4-R Act to stabilize
    railroads financially. Dep’t of Revenue v. ACF Indus., Inc., 
    510 U.S. 332
    , 336, 
    114 S. Ct. 843
    , 846 (1994). This goal implies that an offending tax must disadvantage
    railroads; I fail to see how a tax that places rail carriers in the same tax position as
    their competitors—or a better one—could threaten railroads’ financial stability. So
    it is clear to me that Congress enacted § 11501(b)(4) to eliminate tax schemes that
    impose a greater tax burden on railroads than other taxpayers. This purpose is
    explicit in the first three subsections of § 11501(b), each of which prohibits
    taxation methods that assess or tax rail carriers’ property at a higher rate than other
    taxpayers. See § 11501(b)(1)–(3). By outlawing “another tax that discriminates”
    in the final subsection, Congress specifically targeted taxes that have a similar
    effect as those referred to in the previous three—placing a greater tax burden on
    railroads than other taxpayers for the same taxable item or event. In finding
    discrimination against rail carriers without determining whether rail carriers have
    actually been disadvantaged, the majority opinion flouts the language of the statute
    and Congress’s clear intent.
    25
    Case: 12-14611        Date Filed: 07/01/2013       Page: 26 of 28
    Turning now to the State’s justification, I agree with the district court that
    the State has met its burden to show that the tax exemption for motor carriers was
    not discriminatory against railroads.
    As I explained above, a tax discriminates against railroads in violation of
    § 11501(b)(4) if the tax imposes a greater tax burden on railroads than it does on
    comparable taxpayers. The district court found that rail carriers paid less state tax
    on fuel than motor carriers during the period in question and that, even adding the
    local taxes imposed on rail carriers (and without adding local excise taxes paid by
    motor carriers), rail carriers and motor carriers paid “essentially the same” tax.
    CSX III, 892 F. Supp. 2d at 1313. These factual findings are not challenged on
    appeal.    And I cannot conclude from these findings that railroads have been
    competitively disadvantaged in any way by the sales and use taxes’ exemptions for
    motor carriers.5 I would hold that the State has met its burden to justify the
    5
    CSX contends that, even if rail carriers face the same tax burden as motor carriers in
    terms of purchasing and consuming fuel, rail carriers are still disadvantaged because they must
    maintain their own rights-of-way (tracks) while motor carriers’ rights-of-way (highways) are
    maintained in part by the excise taxes they pay. CSX argues that the district court’s refusal to
    consider these uneven operating expenses in its comparison to the two taxes, see CSX III, 892 F.
    Supp. 2d at 1314–15, was error because any analysis of relative tax burdens must include an
    analysis of the tangible benefits received or not received.
    I disagree. True, railroads have to maintain their tracks. But that burden is not a tax
    burden that the 4-R Act prohibits, and no tax affects that burden. Say, for example, that the State
    eliminated both the motor-fuel excise tax and the motor-carrier exemptions in the sales and use
    taxes, leaving a system in which rail carriers and motor carriers paid identical 4% taxes on the
    purchase and use of their fuel. By CSX’s logic, even that totally equal tax scheme would
    disadvantage railroads in violation of the 4-R Act because railroads have higher overhead
    26
    Case: 12-14611        Date Filed: 07/01/2013       Page: 27 of 28
    differential treatment and, therefore, that the tax exemption does not discriminate
    against rail carriers within the meaning of § 11501(b)(4).
    B. Water Carriers
    The district court held that the sales and use taxes’ exemptions for water
    carriers did not discriminate against rail carriers in violation of the 4-R Act, in part
    because CSX “fail[ed] to meet it[s] evidentiary burden of proof.” CSX III, 892 F.
    Supp. 2d at 1316. This conclusion is not entirely unreasonable; after all, the
    Supreme Court in CSX II did hint that the rail carrier must “prove the alleged
    discrimination” to prevail. CSX II, 131 S. Ct. at 1109 n.8 (“Whether the railroad
    will prevail—that is, whether it can prove the alleged discrimination—depends on
    whether the State offers a sufficient justification . . . .”).
    But the district court required too much of CSX. The rail carrier bringing a
    § 11501(b)(4) claim can establish its prima facie case simply by showing that the
    tax in question exempts competitors.                 See id. at 1108 (noting that a state
    discriminates against one group of taxpayers by charging them a higher tax rate
    than another group). It then becomes the state’s burden to show that the tax did not
    expenses. Motor carriers still would not be responsible for maintaining the public highways of
    Alabama.
    The difference in right-of-way maintenance costs has no place in the comparison of tax
    burdens. That railroads must pay for their own tracks is the inherent burden of operating a
    transportation network on private rights-of-way. In other words, it is a fundamental competitive
    disadvantage that railroads face. Congress did not intend the 4-R Act to eliminate all of
    railroads’ competitive disadvantages, only those created by taxes. And here, the State has shown
    that the sales and use tax exemptions for motor carriers creates no tax disadvantage for railroads.
    27
    Case: 12-14611       Date Filed: 07/01/2013   Page: 28 of 28
    in fact discriminate against the railroad. See id. at 1109 n.8 (“[W]hether [the
    railroad] can prove the alleged discrimination[ ]depends on whether the State
    offers a sufficient justification . . . .”).
    In requiring more from CSX than a showing that the tax exempts water
    carriers, the district court muddied the two-step inquiry and applied an incorrect
    legal standard. When a district court uses the wrong legal standard, we can remand
    for application of the appropriate standard. See Kearse v. Sec’y, Fla. Dep’t of
    Corr., 
    669 F.3d 1197
    , 1198 (11th Cir. 2011). Accordingly, I would remand this
    case so the district court can apply the correct standard (based on the existing
    record) and determine whether the State has offered sufficient justification for the
    tax exemption given to water carriers.
