ORDER ON RESPONDENTS MOTIONS FOR SUMMARY JUDGMENT
U.S. Steel Corp. (U.S. Steel) appeals the final determination of the Indiana Board of Tax Review (Indiana Board) dismissing its Petitions for Correction of Error (188 Petitions) for the 1994-1996 tax years (years at issue). The case is currently before the Court on the Respondents' Motions To Dismiss under Indiana Trial Rule 12(B)(6).
ISSUES
I. Whether the Indiana Board erred when it dismissed U.S. Steel's 138 *1211Petitions for lack of subject matter jurisdiction; and
II. Whether the Indiana Board erred when it found that U.S. Steel improperly brought its claim in a 183 Petition.
For the following reasons, the Court DENIES the Respondents' motions.
FACTS AND PROCEDURAL HISTORY
U.S. Steel is a steel manufacturing plant in Lake County, Indiana, where it owns real and personal property. On May 5, 1998, U.S. Steel filed more than 100 Form 133 Petitions in which it claimed that the property taxes it paid for the years at issue were illegal as a matter of law because Lake County tax officials had improperly removed more than $210 million in assessed value from the County's tax rolls and, as a result, the County's tax rate was overstated, causing U.S. Steel to overpay its taxes." 2
The Lake County Property Tax Assessment Board of Appeals (PTABOA) denied the petitions. U.S. Steel appealed the PTABOA's determination to the State Board of Tax Commissioners. On August 6, 2002, the Indiana Board of Tax Review (Indiana Board)3 issued a final determination dismissing U.S. Steel's 188 Petitions for lack of subject matter jurisdiction. In the alternative, the Indiana Board held that U.S. Steel should have first appealed its tax rate under Indiana Code Section 6-1.1-17 et seq., and that U.S. Steel's claim was improper for a 133 Petition because it implicated the subjective discretion of tax officials. \
On September 5, 2002, U.S. Steel initiated an original tax appeal. The Respondents filed several motions to dismiss U.S. Steel's appeal, which, on October 80, 2002, the Court converted to motions for summary judgment.4 The Court held a hearing on the Respondents' motions on February 7, 2008. Additional facts will be supplied as needed.
ANALYSIS AND OPINION
Standard of Review
This Court gives great deference to final determinations of the Indiana Board when it acts within the seope of its authority. Wittenberg Lutheran Vill. Endowment Corp. v. Lake County Prop. Tax Assessment Bd. of Appeals, 782 N.E.2d 483, 486 (Ind. Tax Ct.2003). Consequently, the Court will reverse a final determination of the Indiana Board only if it is arbitrary, capricious, an abuse of disceretion, or otherwise not in accordance with law; contrary to constitutional right, pow*1212er, privilege, or immunity; in excess of statutory jurisdiction, authority, or limitations, or short of statutory jurisdiction, authority, or limitations;. without observance of procedure required by law; or unsupported by substantial or reliable evidence. Id. at 486-87 (citing Inp.Cop® § 33-3-5-14.8(e)(1)-(5) (Supp.2001) (quotation marks omitted)). Summary judgment is proper only when no genuine issues of material fact exist and the moving party is entitled to judgment as a matter of law. Ind. Trial Rule 56(C).
Discussion
I. The Indiana Board's subject matter jurisdiction
The first issue is whether the Indiana Board erred when it dismissed U.S. Steel's claim for lack of subject matter jurisdiction.5 Pursuant to Indiana Code Section 6-1.5-4-1, the Indiana Board has jurisdiction over all appeals concerning: "(1) the assessed valuation of tangible property; [](2) property tax deductions; [](8) property tax exemptions; [and] (4) property tax credits [ ] that are made from a determination by an assessing official or a county property tax assessment board of appeals to the Indiana [Bloard under any law." Inp.Copm . § 6-1.5-4-1(a) (Supp. 2002) (previously codified at Inp.Copr § 6-1.1-80-11(c) (1998)). The Indiana Board determined that the basis of U.S. Steel's claim concerned the assessed value of tangible property, but nevertheless disclaimed subject matter jurisdiction because U.S. Steel's claim also involved Lake County's tax rate, which it concluded was beyond its statutory jurisdiction as set forth in Indiana Code Section 6-1.5-4-1 (Pet. for Judicial Review, App. A at 5-6.) The Indiana Board, however, is incorrect.
Tax Porutoy § 5.2.1 (1997). In general, property taxes are either rate-driven or budget-driven. Int't Ass'n or Assessince OrricEas, Stanparp on PRroPER-In a rate-driven system, a taxing unit's assessed value is multiplied by a pre-determined tax rate to arrive at the budget; although assessed value in the taxing unit may change, the tax rate does not. Id. In a budget-driven system, a budget is publicly agreed upon and then divided by the taxing unit's assessed value; the resulting quotient is the tax rate. Id. "In this case, the rate is merely a mathematical result and floats upward or downward, depending on the assessed value in the unit of government." Id. (emphasis added). Hence, in a budget-driven system, two types of appeals necessarily implicate the tax rate: (1) appeals that concern assessed value (ie., the denominator in the tax rate formula), and (2) appeals that concern a budget or tax levy (Le., the numerator in the tax rate formula). See generally Stamparp on Property Tax Poutoy at § 5.2.1.
Lake County is a budget-driven system. (Amended R. at 20.) When U.S. Steel challenged the removal of assessed value from Lake County's tax rolls, it necessarily implicated the issue of Lake County's tax rate. This implication, the Indiana Board maintains, was enough to strip it of subject matter Jurisdiction under Indiana Code Section 6-1.1-4-1. To read Indiana Code Section 6-1.5-4-l(a)(l) so narrowly, however, would render it a nullity because the Indiana Board could disclaim subject matter jurisdiction over all appeals concerning assessed valuation on *1213grounds that they necessarily implicate a tax rate. This Court presumes that the Legislature did not intend to enact a nullity when it gave the Indiana Board jurisdiction over appeals concerning "the assessed valuation of tangible property." See IL.C. 6-1.5-4-1(a)(1); Walker Mfg. Co. v. Dep't of Local Gov't Fin., 772 N.E.2d 1, 6 (Ind.Tax Ct.2002) (rejecting an interpretation of the law that would nullify a jurisdictional statute). Instead, when a taxpayer's appeal implicates a budget-driven system's tax rate (as U.S. Steel's appeal does), then the Indiana Board must determine whether the appeal concerns assessed value or whether it concerns a budget or tax levy. If the Indiana Board determines that the taxpayer's appeal concerns assessed value, then Indiana Code Section 6-1.5-4-1 gives the Indiana Board subject matter jurisdiction over the appeal. I1.C. § 6-1.5-4-1(a)(1).
Here, the Indiana Board admitted that U.S. Steel's appeal concerned assessed value; thus, the Indiana Board has subject matter jurisdiction over U.S. Steel's 183 Petition despite the fact that its claim implicates Lake County's tax rate. See id. The Indiana Board's reason for disclaiming subject matter jurisdiction therefore fell "short of fits] statutory jurisdiction[.]" ILC. § 83-3-5-14.8(e)(3). Hence, the Court DENIES the Respondents' motions for summary judgment. The Court GRANTS summary judgment to U.S. Steel on this issue.6
II. Whether U.S. Steel's claim was properly brought in a 133 Petition
'The Respondents argue that even if the Indiana Board has subject matter jurisdiction over U.S. Steel's claim, U.S. Steel's appeal must still fail because U.S. Steel did not first appeal Lake County's tax rate under Indiana Code Section 6-1.1-17 et seq.7 In the alternative, the Respondents argue that U.S. Steel cannot bring its claim in a 133 Petition because it challenges the subjective discretion of the tax officials. The Respondents are wrong on both counts.
A. Whether U.S. Steel should first have appealed under I.C. § 6-1.1-17 et seq.
The Respondents argue that before U.S. Steel filed its 138 Petitions, it should have appealed Lake County's tax rate pursuant to Indiana Code Section 6-1.1-17 et seq. Indiana Code Section 6-1.1-17-5 does not, however, grant taxpayers a right to appeal a tax rate. Rather, the law merely provides that ten or more taxpayers may object to the "tax rate ... of a political subdivision[.]"8 Ixp.Copm § 6-1.1-17-5(b) (1998). Onee an objection has *1214been made, tax officials simply must adopt a "finding," which is presented along with the budget to the County Board of Tax Adjustment (County Board). See Inp. Cope §§ 6-1.1-17-5(b), (c), & (d) (1998). The County Board is without authorization to even address the taxpayers' objection. See Imp.Cope § 6-1.1-17-6 (1998). Thus, Indiana Code Section 6-1.1-17-5 is merely a mechanism for ten or more taxpayers to place their objection on record."9
The right of appeal afforded to ten or more taxpayers is "to initiate an appeal . on a political subdivision's budget [.]" § 6-1.1-17-13 (1998). U.S. Steel's claim, however has nothing to do with Lake County's budget.10 Therefore, to require U.S. Steel to object to its tax rate under Indiana Code Section 6-1.1-17 et seq. would not result in a final determination that it could have appealed to the then-State Board. Consequently, the procedures available to U.S. Steel under Indiana Code Section 6-1.1-17 et seq. are irrelevant to U.S. Steel's 183 Petitions.11
B. Subjectivity and 133 Petitions
In the alternative, the Respondents argue that U.S. Steel improperly brought its claim in a 188 Petition because the removal of assessed value from Lake County's tax rolls involved subjective judgment on the part of tax officials, and the only errors reviewable by a 188 Petition are those which can be corrected without resort to subjective judgment.12 Again, the Respondents are incorrect.
A taxpayer may file a 188 Petition to request a correction of errors that result from one or more of the following reasons:
(1) The description of the real property was in error.
(2) The assessment was against the wrong person.
(3) Taxes on the same property were charged more than one (1) time in the same year.
(4) There was a mathematical error in computing the taxes or penalties on the taxes.
(5) There was an error in carrying delinquent taxes forward from one (1) tax duplicate to another.
(6) The taxes, as a matter of law, were illegal.
*1215(7) There was a mathematical error in computing an assessment.
(8) Through an error of omission by any state or county officer the taxpayer was not given credit for an exemption or deduction permitted by law.
Inp.Copg § 6-L1-15-12(@) (1998). U.S. Steel brings its claim under "[t]he taxes, as a matter of law, were illegal" provision of subdivision (6).
When a taxpayer files a 183 Petition, it "must be able to show with probative evidence that the error is an objective error, and not a subjective error." Barth, Inc. v. State Bd. of Tax Comm'rs, 756 N.E.2d 1124, 1128 (Ind.Tax Ct.2001) (emphasis added). Thus, taxpayers cannot use the 183 Petition to challenge any part of their assessment that implicates an official's exercise of lawful subjective discretion, le., discretion that is authorized by law. See King Indus. Corp. v. State Bd. of Tax Comm'rs, 699 N.E.2d 338, 340 n. 4 (Ind.Tax Ct.1998) (noting that "a certain amount of ... subjective judgment must be included in the assessment process").
In this case, however, U.S. Steel challenges the allegedly unlawful subjective discretion-ie., discretion that is not authorized by law-of Lake County in removing assessed value from its tax rolls. The Indiana Board cannot, then, invoke the "subjective" discretion of those tax officials as a reason to deny U.S. Steel's 133 Petitions, because no tax official is vested with discretion to act unlawfully. See Ind. Cope § 6-1.1-2-8 (1998) (providing that "[the] total tax rate ... shall be determined in the manner provided by law" (emphasis added)); Hennel v. Bd. of Comm'rs of Vanderburgh County, 132 Ind. 32, 31 N.E. 462, 463 (1892) (holding that when an assessor levies a tax without authority to do so, the assessment, is void); Newsom v. Bd. of Comm'rs of Bartholomew County, 92 Ind. 229, 233, 1883 WL 5754 (1883) (indicating that an illegal tax is one not levied and collected "in the manner prescribed by law"); Board of Comm'rs of Howard County v. Armstrong, 91 Ind. 528, 536 (1883) (holding that illegal taxes are "without authority of law as to the manner in which they were made"); State v. McGinnis, 34 Ind. 452, 454 (1870) (voiding the acts of an unlawfully constituted board of equalization); Donch v. Bd. of Comm'rs of Lake County, 4 Ind.App. 374, 30 N.E. 204, 206 (1892) (holding that "[wlhen the amount which shall be paid for the support of government ... has been fixed by a method prescribed by law, that must be regarded as the amount demanded by the law; and it cannot be considered as otherwise than unjust and wrongful for an officer, without authority ..., to assume to change the requirement of the law, and thereupon to collect a larger amount"). Accordingly, the Indiana Board's dismissal of U.S. Steel's 183 Petitions because they involve a subjective determination is baseless.
Indiana Code Section 6-1.1-15-12(a)(6) provides taxpayers with a remedy when their "taxes, as a matter of law, [are] ilegal." 1.0. § 6-1.1-15-12(a)(6) (emphasis added). To determine something "as a matter of law" simply means to apply the law to undisputed, material facts. See Central Realty, Inc. v. Hillman's Equipment, Inc., 253 Ind. 48, 246 N.E.2d 383, 389 (1969); Young v. Citizens' St. R. Co., 148 Ind. 54, 47 N.E. 142, 143 (1897); Union Sch. Tp. v. First Nat. Bank of Crawfordsville, Ind., 102 Ind. 464, 2 N.E. 194, 197 (1885). Here, U.S. Steel and the Respondents do not dispute that assessed value was removed from Lake County's *1216tax rolls; hence, the parties do not dispute any material facts.13 The only question is whether Lake County's removal of assessed valuation from its tax rolls (and, hence, the resulting tax rate) was, as a matter of law, illegal-a question that falls squarely within the ambit of the 188 Petition. See 1.C. § 6-1.1-15-12(a)(6). Thus, it is appropriate for U.S. Steel to claim in its 138 Petitions that its taxes, as a matter of law, were illegal. The Indiana Board acted "without observance of procedure required by law" when it declined to hold a hearing on and reach the merits of U.S. Steel's claim. Sse Inp.Copnm § 83-8-5-14.8(e)(4). The Court, therefore, DENIES the Respondents' motions for summary judgment on this issue and GRANTS summary judgment to U.S. Steel.14
The Court REMANDS U.S. Steel's 183 Petitions to the Indiana Board. On remand, the Indiana Board shall hold a hearing pursuant to the provisions of Indiana Code Section 6-1.1-15-12(e). See Inp. Cope § 6-1.1-15-12(e) (providing that a 133 Petition is subject to the appeals procedure under sections 4 through 8 of Indiana Code Section 6-1.1-15). After such hearing, the Indiana Board shall reach the merits of U.S. Steel's claim.
CONCLUSION
The Court DENIES the Respondents' motions for summary judgment and GRANTS summary judgment to U.S. Steel. The Court REMANDS U.S. Steel's 133 Petitions to the Indiana Board. On remand, the Court ORDERS the Indiana Board to reach the merits of U.S. Steel's claims in a manner consistent with this opinion.
