WENTWORTH, J.
The Metropolitan School District of Pike Township (the School District) appeals the Department of Local Government Finance's (DLGF) final determination recalculating its capital projects fund ("CPF") levy property tax rate for 2011. The appeal presents one issue for this Court to decide: whether the DLGF's recalculation was correct.
FACTS AND PROCEDURAL HISTORY
The School District is a public school corporation located in Marion County, Indiana. On October 18, 2010, the School District adopted its proposed budget for 2011 and submitted it to the DLGF for approval. As part of that budget proposal, the School District estimated the property tax rate necessary to generate its CPF levy.
On January 21, 2011, the DLGF notified the School District that, inter alia, it was reducing the School District's estimated CPF levy property tax rate pursuant to the formula provided in Indiana Code § 6-1.1-18-12. The School District subsequently filed a protest challenging the rate reduction. On February 11, 2011, the DLGF issued a final determination denying the School District's protest and certifying its budget order as final.
On March 9, 2011, the School District initiated this original tax appeal. The Court heard the parties' oral arguments on October 25, 2011. Additional facts will be supplied as necessary.
LAW
The property tax rate applicable to a public school corporation's CPF levy is capped at $0.4167 per each $100 of assessed valuation within the taxing district. Ind.Code § 20-46-6-5 (2010). The DLGF annually adjusts that maximum rate, however, "to account for the change in assessed value of real property that results from ... an annual adjustment of the assessed value of real property under IC 6-1.1-4-4.5[] or [] a general reassessment of real property under IC 6-1.1-4-4." I.C. § 20-46-6-5; Ind.Code § 6-1.1-18-12(c), (f) (2010). To make the annual adjustment, the legislature provided the DLGF with the following statutory formula:
STEP ONE: Determine the maximum rate for the political subdivision levying a property tax ... under the statute for the year preceding the year in which the annual adjustment or general reassessment takes effect.
STEP TWO: Determine the actual percentage increase (rounded to the nearest one-hundredth percent (0.01%)) in the assessed value (before the adjustment, if any, under IC 6-1.1-4-4.5) of the taxable property from the year preceding the year the annual adjustment or general reassessment takes effect to the year that the annual adjustment or general reassessment takes effect.
STEP THREE: Determine the three (3) calendar years that immediately precede the ensuing calendar year and in which a statewide general reassessment of real property does not first take effect.
STEP FOUR: Compute separately, for each of the calendar years determined in STEP THREE, the actual percentage increase (rounded to the nearest one-hundredth percent (0.01%)) in the assessed value (before the adjustment, if any, under IC 6-1.1-4-4.5) of the taxable property from the preceding year.
STEP FIVE: Divide the sum of the three (3) quotients computed in STEP FOUR by three (3).
STEP SIX: Determine the greater of the following:
(A) Zero (0).
(B)The result of the STEP TWO percentage minus the STEP FIVE percentage.
STEP SEVEN: Determine the quotient of the STEP ONE tax rate divided by the sum of one (1) plus the STEP SIX percentage increase.
I.C. § 6-1.1-18-12(e).1
This Court previously held that steps two and four of the above formula require the use of a zero value when there is no increase in a school district's assessed value from one year to the next. See DeKalb Cnty. E. Cmty. Sch. Dist. v. Dep't of Local Gov't Fin., 930 N.E.2d 1257, 1260-61 (Ind. Tax Ct.2010). Likewise, steps two and four require the use of a zero value, as opposed to a negative value, when a school district's assessed value actually decreases.2 See id. (footnote added).
ANALYSIS
The sole dispute in this case is whether the DLGF properly applied the formula in Indiana Code § 6-1.1-18-12(e) when it adjusted the School District's CPF levy property tax rate. Because this is a pure question of law, the Court will employ a de novo standard of review. See, e.g., Pike Twp. Educ. Found., Inc. v. Rubenstein, 831 N.E.2d 1239, 1241 (Ind.Ct.App.2005).
On appeal, the School District admits that the DLGF applied DeKalb in its 2011 CPF levy property tax rate adjustment by using zeros in steps two and four of the statutory formula. Nevertheless, the School District contends that DeKalb required the DLGF to do something more. The School District asserts that because a CPF levy property tax rate calculation under Indiana Code § 6-1.1-18-12(e) is necessarily affected by previous years' rate calculations,
the DLGF should have accounted for its [improper] use of negative numbers in [steps two and four of] its calculations for 2007-2010 by rerunning those calculations and reflecting the resulting rate in Step 7 for 2010 as the rate in Step 1 for 2011. This w[ould have] ... produce[d] a rate of .3100 for Step 1 for 2011.3
(Cert. Admin. R. at 277 (footnote added).) (See also Pet'r Br. at 2-3, 8-10.)
In response, the DLGF argues that because the School District has protested only the 2011 budget order, it is improper to go back and recalculate step seven rates for prior "closed" years. (See Resp't Resp. Br. at 5-6.) (See also Cert. Admin. R. at 407 (stating that because the School District never appealed its step seven rate from 2010 or an earlier year, "the STEP ONE value for 2011 is the STEP SEVEN value that was determined for 2010, and upon which a budget order was issued").) More specifically, the DLGF contends that the School District's appeal
is asking this Court to determine the accuracy of [its] CPF tax rate calculations for the tax years 2007, 2008, 2009, and 2010. [The School District never] protested [the rate calculations for those years, however, and] the DLGF [therefore never] issued a final determination in response[.] ... Thus, this Court lacks [subject matter] jurisdiction to alter DLGF calculations ... for [those] tax years ... and may not order the DLGF to provide the retroactive cumulative relief [the School District] now seeks. ... In short, [the School District] is not asking the Court to apply DeKalb to the year [it] protested, instead [it] is seeking to retroactively apply DeKalb to tax years that were never protested.
(Resp't Resp. Br. at 5-6.) The DLGF's argument fails, however, for two interrelated reasons.
First, when a judicial opinion rendered in a civil case makes a pronouncement of the law, that pronouncement has not only prospective effect, but also retrospective effect. Don Medow Motors, Inc. v. Grauman, 446 N.E.2d 651, 654 (Ind.Ct. App.1983) (citing Center Sch. Twp. v. State ex rel. Bd. of Sch. Comm'rs, 150 Ind. 168, 49 N.E. 961, 963 (1898)). This is so because, in theory, "the law has not changed; the last judicial decision is said to have enunciated the law as it has always existed." Id. (emphasis added) (citations omitted). Thus, when the 2010 DeKalb decision explained why steps two and four of the formula contained in Indiana Code § 6-1.1-18-12(e) required zero values as opposed to negative values, that meant that the DLGF should have been using those zero values since 2007 when Indiana Code § 6-1.1-18-12(e) first became applicable to public school corporations. See supra note 1.
Second, the DLGF has acknowledged that the formula contained in Indiana Code § 6-1.1-18-12(e) is "cumulative" in its effect, as each year's CPF levy property tax rate calculation plays a part in successive years' rate calculations. (See Oral Argument Tr. at 34-35.) See also I.C. § 6-1.1-18-12(e). Nonetheless, the DLGF's argument in this case — that the statute requires it merely to transfer the School District's 2010 step seven value to step one of the current year's calculation — is contrary to the plain and ordinary meaning of the statute and yields an illogical result. Indeed, step one of the formula in Indiana Code § 6-1.1-18-12(e) specifically instructs the DLGF to "determine" the maximum rate for the prior year, not just passively "carry it over" or "transfer it." See, e.g., Johnson Cnty. Farm Bureau Coop. Ass'n v. Indiana Dep't of State Revenue, 568 N.E.2d 578, 580-81 (Ind. Tax Ct.1991) (explaining that the best evidence of the legislature's intent in enacting a statutory provision is found in the actual language used within the statute itself), aff'd by 585 N.E.2d 1336 (Ind.1992). Moreover, logic dictates that previous CPF levy property tax rate calculation errors should not be allowed to corrupt the accuracy of current and future years' calculations. See, e.g., Uniden Am. Corp. v. Indiana Dep't of State Revenue, 718 N.E.2d 821, 828 (Ind. Tax Ct.1999) (explaining that statutes must be read in such a way that prevents an illogical or absurd result). Accordingly, the DLGF's use of negative numbers in steps two and four of the formula for tax years 2007 through 2010 to produce a CPF levy property tax rate calculation for 2011 is wrong: it should have used zeros as it was statutorily required.4
As a final matter, the Court does not agree with the DLGF's contention that it lacks subject matter jurisdiction in this case because the School District seeks retroactive relief for tax years it never protested and for which no final determinations were therefore issued. Indeed, the DLGF misunderstands what "relief" is really at issue in this case.5 The School District does not ask the DLGF to recalculate the CPF levy property tax rate for years 2007 through 2010 using zero values instead of negative values in steps two and four to recover "lost" funds from each of those years.6 Rather, the School District simply seeks to correct those erroneous calculations for the sole purpose of ensuring the accuracy of its 2011 CPF levy property tax rate calculation, which is the subject of the final determination at issue, so that it may levy and collect the funds to which it is statutorily entitled.7
CONCLUSION
For the foregoing reasons, the DLGF's final determination in this matter is REVERSED. The matter is REMANDED to the DLGF with instructions to recalculate the School District's CPF levy property tax rates for 2007 through 2010 by using zero values instead of negative values in steps two and four of the formula contained in Indiana Code § 6-1.1-18-12(e). These corrections will result in both a step one and a step seven value for 2011 of 0.3100.8 (See Cert. Admin. R. at 283 (footnote added).)
