OPINION
¶ 1 The question we address is whether Arizona’s statutory provision governing the priority of mechanics’ liens (Arizona Revised Statutes (“AR.S.”) section 33-992(A)) permits a court to shift lien priorities by applying the doctrine of equitable subrogation. Because § 33-992(A) expressly provides that mechanics’ liens have priority over all subsequent encumbrances (subject to a narrow exception not applicable here), we hold thаt allowing a subsequent lienholder to equitably subrogate its loan to a position ahead of a mechanic’s lien would contravene the plain statutory requirement. We therefore affirm the superior court’s grant of summary judgment.
BACKGROUND
¶ 2 First National Bank of Arizona provided a $44,000,000 construction loan to Summit at Copper Square, LLC (“Summit”) to build a 165-unit mixed-use commercial and residential condominium project in downtown Phoеnix. The bank recorded a deed of trust on the project to secure Summit’s payment obligations under the construction loan, which was later increased by approximately $10,000,000.
¶ 3 Summit contracted with The Weitz Company (“Weitz”) to serve as the general contractor on the project. Construction commenced, and on January 18, 2006, Weitz served a preliminary twenty-day mechanic’s lien notice. See A.R.S. § 33-992.01. The prоject continued according to the parties’ agreement, with Summit paying Weitz on a monthly basis in response to Weitz’s payment applications. As the project neared completion, however, Summit was unable to pay about $4,000,000 of Weitz’s billed work.
¶ 4 Summit started selling individual condominium units in September 2007, before construction was completed. Ultimately, as relevant here, 92 units were sold. Most of the purchases were financed by various commercial lenders, but some units were sold for cash. Proceeds from the sales were applied to pay off allocated portions of the construction loan, but the outstanding balance of Weitz’s construction contract remained unpaid.
¶ 5 Weitz recorded a mechanic’s lien against the project in May 2008. In November, Weitz filed a complaint seeking to foreclose its lien against, inter alia, the purchasers of the units and the lenders who provided the funds used to finance the purchases (collectively “Lenders”). Lenders moved for partial summary judgment, arguing they were equitably subrogated to First National Bank’s position, and thus had priority over Weitz’s lien. In response, Weitz also sought partial summary judgment, asserting that its lien had priority under A.R.S. § 33-992(A) over all other liens or encumbrances attaching after commencement of the project.
¶ 6 Following oral argument on the motions, the superior court ruled in favor of Weitz, finding it would be improper to apply equitable subrogation because the construction loan had not been fully discharged. The court therefore concluded Weitz’s lien was superior to Lenders’ liens under AR.S.

I. Historical Preference of Mechanics’ Liens
¶ 8 A lien is defined as a “legal right or interest that a creditor has in another’s property, lasting [usually] until a debt or duty that it secures is satisfied.” Black’s Law Dictionary 941 (8th ed.2004). Every person who provides labor or materials for the construction of any building “shall have a lien” on such building for the work done or materials supplied. AR.S. § 33-981. Enforcement of the lien is contingent upon compliance with detailed statutory procedures, see A.R.S. §§ 33-981 to -1008, and the lien’s priority is governed by § 33-992(A), which provides in part:
The hens provided for in this article ... are preferred to all liens, mortgages or other encumbrances upon the property attaching subsequent to the time the labor was commenced or the materials were commenced to be furnished except any mortgage or deed of trust that is given as security for a loan made by a construction lender ... if the mortgage or deed of trust is recorded within ten days after labor was commenced or the materials were commenced to be furnished.
(Emphasis added.) Legislative recognition that mechanics’ liens have priority over subsequent liens has been in existence since 1865, almost half a century before statehood:
[T]he liens created by this aсt shall be preferred to every other lien or incum-brance, which shall have been attached upon said property subsequent to the time at which the work was commenced or the materials furnished; but nothing herein contained shall be construed as impairing any valid incumbrance upon the said lands, duly made and recorded before such work was commenced or materials furnished.
Acts of Arizona, 1865, p. 38 sec. 4; see also Compiled Laws of thе Territory of Arizona as Chapter XXVII, see. 4 (1874); Revised Statutes of Arizona Territory, Title 40, Ch. 2, p. 759-64 (1901); Revised Statutes of Arizona Civil Code, Title 29, Ch. 2, p. 1256, ¶ 3658 (1913).
¶ 9 As recognized by our supreme court, the purpose of the mechanics’ lien statutes is to protect the rights of those who furnish labor and materials to improve another person’s property. Collins v. Stockwell,
II. Plain Statutory Language
¶ 10 In construing AR.S. § 33-992(A), our fundamental goal is to give effect to legislative intent. Hall v. Read Dev., Inc.,
¶ 11 The language of § 33-992(A) is unambiguous. It expressly provides that mechanics’ liens have priority over “all liens, mortgages, or other encumbrances” (excеpt for construction loans) attaching subsequent to the time the labor was commenced or materials provided. In this case, it is undisputed that Weitz perfected its mechanic’s lien and that the deeds of trust relating to the purchased units attached to the subject property after Weitz commenced work on the project. Therefore, under the plain language of § 33-992(A), Weitz’s mechanic’s lien has рriority over Lenders’ deeds of trust. See Calik v. Kongable,
¶ 12 Lenders argue nonetheless that the doctrine of equitable subrogation is a valid exception to this statutory order of priority, permitting the superior court to elevate the priority of Lenders’ loans to that of the construction loan. Equitable subrogation allows “[o]ne who fully performs an obligation of another, secured by a mortgаge, [to] become[] by subrogation the owner of the obligation and the mortgage to the extent necessary to prevent unjust enrichment.” Sourcecorp, Inc. v. Norcutt,
¶ 13 Asserting that Arizona courts have consistently recognized and applied equitable subrogation in the context of mechanics’ liens, Lenders rely on three prior decisions from this court. See Cont’l Lighting & Contracting, Inc. v. Premier Grading & Utils., LLC,
¶ 14 In Petermarir-Donnelly, the Apache Junction Chamber of Commerce borrowed $10,000 from Eyre, secured by a mortgage on property where the Chamber intended to construct a baseball facility.
¶ 15 Lamb also involved the foreclosure of a mechanic’s lien and a determination of priority.
¶ 16 In fairness to our colleagues who decided the Peterman-Donnelly and Lamb cases, nothing in either decision suggests that the parties in those cases argued or briefed the specific issue we address here— the resolution of a conflict between specific statutory language and an equitable doctrine. In any event, we disagree with those decisions insofar as they may be interpreted to stand for the proposition that a court may apply equitable subrogation to override the plain language of § 33-992(A). See Morgan v. Carillon Inv., Inc.,
III. Legislative Acquiescence
¶ 17 Arizona courts recognize that “[i]f the legislature amends a statute after it has been judicially construed, but does not modify the statute in a manner that changes the court’s interpretation, we presume the legislature approved of the court’s construction and intended that it remain a part of the statute.” Galloway v. Vanderpool,
¶ 18 First, the principle of legislativе acquiescence applies only when a statute has been “construed by the court of last resort.” See, e.g., Sw. Paint & Varnish Co. v. Ariz. Dep’t of Envtl. Quality,
IV. Equity Follows the Law
¶ 20 It is also well-established that equity cannot override unambiguous statutory language. See, e.g., Valley Drive-in Theatre Corp. v. Superior Court,
¶ 21 Lenders have not cited and our research has not revealed any other authority holding that a statute that governs the priority of mechanics’ liens may be superseded by the doctrine of equitable subrogation. Instead, the few cases that have addressed the issue are consistent with our analysis. See, e.g., Ex parte Lawson,
¶ 22 The Nevada Supreme Court’s analysis in the Fontainebleau ease is instructive. In that case, a developer sought to construct a multi-billion dollar casino project in Las Vegas.
¶23 Although the Nevada court had applied the doctrine of equitable subrogation in other contexts, it had never considered how equitable subrogation interacts with Nevada’s statute gоverning the priority of mechanics’ liens. Id. at 1209. Nevada’s mechanics’ lien priority statute originated in 1861, when it was passed by the Legislative Assembly of the Territory of Nevada. 1861 Laws of the Territory of Nevada, eh. 16, at 35. The current statute, Nevada Revised Statutes (“NRS”) 108.225, reads as follows:
1. [Mechanics’] liens ... are preferred to: Any lien, mortgage or other encumbrance which may have attached to the property after the commencement of construction of a work of improvement.
Any lien, mortgage or other encumbrance of which the lien claimant had no notice and which was unrecorded against the property at the commencement of construction of a work of improvement.
2. Every mortgage or encumbrance imposed upon, or conveyance made of, propеrty affected by [mechanics’] liens ... after the commencement of construction of a work of improvement are subordinate and subject to the [mechanics’] liens ... regardless of the date of recording the notices of liens.
Based on this language, the court determined that “[t]he Legislature has spoken and has created a specific statutory scheme whereby a mechanic’s lien is afforded priority over a subsequent lien, mortgage, or encumbrance in order to safeguard payment for work and materials provided for construction or improvements on land.” Fontainebleau,
¶ 24 Consistent with the reasoning in Fon-tainebleau, we conclude that equitable subro-gation cannot operate to supersede the statutory requirement that mechanics’ liens have priоrity over all subsequent encumbrances, except for construction loans filed within the narrow time constraints of the statute. See State ex rel. Morrison v. Anway,
CONCLUSION
¶ 25 For the foregoing reasons, we affirm the superior court’s decision confirming that Weitz’s lien has priority over Lenders’ liens.
