We granted a writ of certiorari to .review the Court of Appeals’ decision in Key Corporate Capital, Inc. v. County of Beaufort, 360 S.C. 513, 602 S.E.2d 104 (Ct.App.2004). We reverse.
FACTS
In 1998 and 1999, respondents Key Corporate Capital, Inc., National Tax Assistance Corporation, and TransAm Tax Certifícate Corporation purchased several properties at Beaufort County tax sales. The Beaufort County Treasurer subsequently voided twelve of these tax sales.' See S.C.Code Ann. § 12-51-150 (2000).1
The parties stipulated to the following facts: (1) the tax sales were voided because the Treasurer discovered “errors, *58oversights, and/or miscommunications within the Beaufort County offices;” (2) the tax sales were not voided “due to any actions or inactions on the part of’ respondents; (3) the tax sales would have been set aside by a court if the Treasurer had not voided them; (4) the County retained the purchase price on each property for at least 28 days, and for three of the properties, the funds were held for over a year; (5) the Treasurer’s Office refunded the full purchase price to respondents; and (6) the County earned a 6% rate of interest on respondents’ funds with an actual earned amount of $28,010.93 in interest.
Seeking the interest their money earned while in the County’s possession, respondents brought suit against the County of Beaufort, the Treasurer of Beaufort County, and the Tax Collector of Beaufort County (collectively “petitioners” or “the County”). One of respondents’ theories for relief was unjust enrichment. Petitioners answered, asserting that respondents were limited to the statutory remedy. The master-in-equity heard the matter and ruled in favor of respondents. Specifically, the master found that: (1) the applicable statute, section 12-51-150, was silent as to interest; and (2) applying the rules of equity, petitioners would be unjustly enriched if they retained the interest earned on respondents’ funds when it was petitioners’ errors that caused them to void the tax sales. Therefore, the master awarded respondents actual damages of $28,010.93.
The Court of Appeals affirmed. Key Corporate, supra. First, the Court of Appeals found that section 12-51-150’s silence on the subject of interest did not “entitle[ ] the County to retain the interest.” Key Corp., 360 S.C. at 516, 602 S.E.2d at 106. The Court of Appeals then reasoned that because other sections within Chapter 51 specifically address interest,2 the Legislature’s omission regarding interest in section 12-51-*59150 required that the rules of equity be applied. Like the master-in-equity, the Court of Appeals found “it would be unjust to allow the County to keep the interest on the purchase prices of tax sales that were voided due to the County’s own errors and omissions;” therefore, the Court of Appeals concluded that respondents were entitled to the interest actually earned while in the County’s possession. Id. at 519-20, 602 S.E.2d at 107-08.
ISSUE
Did the Court of Appeals err in affirming the award of interest to respondents?
DISCUSSION
Petitioners argue that the Court, of Appeals erred in not following the plain and unambiguous language of section 12-51-150 which, at the relevant timé, provided only for a return of the “amount paid” to the successful bidder when a tax sale is voided. Petitioners further contend it was error to apply the principles of equity because the statute provided an adequate remedy at law, i.e., the refund of the purchase price paid by the bidder. We agree with both these arguments.
The sale of the property of a defaulting taxpayer is governed by statute. Durham v. United Cos. Fin. Corp., 331 S.C. 600, 603, 503 S.E.2d 465, 467 (1998). “If a statute’s language is plain, unambiguous, and conveys a clear meaning, the rules of statutory interpretation are not needed and the court has no right to impose another meaning.” Buist v. Huggins, 367 S.C. 268, 276, 625 S.E.2d 636, 640 (2006) (internal quotes and citation omitted). Instead, the words of the statute must be given their plain and ordinary meaning without resorting to subtle or forced construction to limit or expand the statute’s operation. Id. Moreover, “it is beyond this Court’s power to effect a change in the statutes enacted by the Legislature.” State v. Corey D., 339 S.C. 107, 120, 529 S.E.2d 20, 27 (2000); see also Keyserling v. Beasley, 322 S.C. 83, 86, 470 S.E.2d 100, 101 (1996) (this Court does “not sit as a superlegislature to second guess the wisdom or folly of decisions of the General Assembly”).
*60We need not go any further than the plain language of section 12-51-150 to determine that it was error to award respondents the earned interest. At the time in question, this statute provided a clear remedy if a tax sale was voided — a “refund” of “the amount paid” to the successful bidder. If the Legislature had intended the County to earn and then refund interest, it could easily have specified these requirements in the statute as it did in sections 12-51-100 and 12-51-130. See footnote 2, swpra.
Indeed, the Legislature amended this section just last year to expressly provide that when a tax sale is voided, the purchaser would be provided a refund plus actual interest earned: Section 12-51-150 now reads as follows, in pertinent part:
If the official in charge of the tax sale discovers before a tax title has passed that there is a failure of any action required to be properly performed, the official may void the tax sale and refund the amount paid, plus interest in the amount actually earned by the county on the amount refunded, to the successful bidder.
S.C.Code Ann. § 12-51-150 (Supp.2006) (emphasized language effective June 14, 2006).
We have long acknowledged the presumption that in adopting an amendment to a statute, the Legislature intended to change the existing law. See Vernon v. Harleysville Mut. Cas. Co., 244 S.C. 152, 155, 135 S.E.2d 841, 844 (1964); see also North River Ins. Co. v. Gibson, 244 S.C. 393, 398, 137 S.E.2d 264, 266 (1964) (where the Court recognized “the rule of construction that the adoption of an amendment which materially changes the terminology of a statute ... raises a presumption that a departure from the original law was intended”); Hyde v. S.C. Dep’t of Mental Health, 314 S.C. 207, 210, 442 S.E.2d 582, 583 (1994) (Toal, J., dissenting) (“Where a statute has been amended, there is a presumption that the legislature intended to change the law.”).3
We see no reason not to apply this presumption and therefore conclude that the Legislature’s amendment to section 12-*6151-150 sought to effect a change in the law. Because the amendment materially changed the terminology of the statute, a departure from existing law clearly was intended, rather than a clarification of original intent. See North River Ins. Co. v. Gibson, supra. In fact, to hold otherwise would indicate that this amendment essentially was a futile act, which we are disinclined to do. See Denene, Inc. v. City of Charleston, 352 S.C. 208, 212, 574 S.E.2d 196, 198 (2002) (“The Court must presume the legislature did not intend a futile act, but rather intended its statutes to accomplish something.”); TNS Mills, Inc. v. S.C. Dep’t of Revenue, 331 S.C. 611, 503 S.E.2d 471 (1998) (same).
Accordingly, we hold that the plain language of the prior version of section 12-51-150 clearly limits respondents’ remedy to a refund of the purchase price without interest.
Moreover, we find it was error to fashion an equitable remedy in this case. While equitable relief is generally available where there is no adequate remedy at law, an adequate legal remedy may be provided by statute. Santee Cooper Resort, Inc. v. S.C. Pub. Serv. Comm’n, 298 S.C. 179, 185, 379 S.E.2d 119, 123 (1989). Indeed, a “court’s equitable powers must yield in the face of an unambiguously worded statute.” Id. There is simply nothing inadequate about the remedy of a full refund provided by the plain language of the prior version of section 12-51-150; hence, there was no reason for the lower courts to resort to equity principles.
Finally, as to respondents’ argument that an equitable remedy is justified by the Court of Appeals’ opinion in H & K Specialists v. Brannen, 340 S.C. 585, 532 S.E.2d 617 (Ct.App. 2000), we simply disagree. In II & K Specialists, the Court of Appeals held that section 12-51-1004 applied to the case *62because the tax sale was set aside in a later court action. The Court of Appeals deemed the master-in-equity’s return of the property to the delinquent taxpayers “as the ultimate redemption” thereby triggering section 12-51-100’s remedy of the return of the purchase price plus interest to the successful bidder. Id. at 588, 532 S.E.2d at 619. While the Court of Appeals did note that the County’s errors and omissions created the “inequitable situation” present in the case,5 this does not establish that the Court of Appeals fashioned an equitable remedy in favor of the appellant. Id. at 589, 532 S.E.2d at 620. On the contrary, the Court of Appeals merely held that the setting aside of the tax sale was tantamount to a redemption which triggered section 12-51-100 and the remedy contained therein. In the instant case, however, there is no question that the applicable statute is section 12-51-150 which, in its previous form, did not provide the successful bidder with interest on the purchase price.
CONCLUSION
In sum, we hold that the version of section 12-51-150 in effect at the relevant time only required the County, upon voiding the tax sales, to refund the purchase price, and not the interest, to respondents. Therefore, the Court of Appeals’ opinion is
REVERSED.
MOORE and BURNETT, JJ., concur. TOAL, C.J., dissenting in a separate opinion in which PLEICONES, J., concurs.. The version of section 12-51-150 relevant to the instant action states as follows:
In the case that the official in charge of the tax sale discovers before a tax title has passed, the failure of any action required to be properly performed, the official may void the tax sale and refund the amount paid to the successful bidder. If the full amount of the taxes, assessments, penalties, and costs have not been paid, the property must be brought to tax sale as soon as practicable.
S.C.Code Ann. § 12-51-150 (2000) (emphasis added). As will be discussed infra, this statutory section was recently amended to also provide .to the successful bidder any interest earned on the purchase price. See 2006 S.C. Act No. 386, effective June 14, 200(S.
. See S.C.Code Ann. § 12-51-100 (where the defaulting taxpayer redeems the property, the successful bidder at tire tax sale is entitled to be "refunded the purchase price plus the interest"); S.C.Code Ann. § 12-51-130 (County is directed to invest amounts paid at a tax sale that exceed the amount owed by delinquent taxpayer in a separate account "so as not to be idle,” and if taxpayer does not claim the overage within the specified time period, County is entitled to both the overage and "the earnings for keeping the overage").
. But see Stuckey v. State Budget and Control Bd., 339 S.C. 397, 401, 529 S.E.2d 706, 708 (2000) ("A subsequent statutory amendment may be interpreted as clarifying original legislative intent.”).
. This section, entitled "Cancellation of sale upon redemption; notice to purchaser; refund of purchase price,” states:
Upon the real estate being redeemed, the person officially charged with the collection of delinquent taxes shall cancel the sale in the tax sale book and note thereon the amount paid, by whom and when. The successful purchaser, at the delinquent tax sale, shall promptly be notified by mail to return the tax sale receipt to the person officially charged with the collection of delinquent taxes in order to be expeditiously refunded the purchase price plus the interest provided in Section 12-51-90.
*62S.C.Code Ann. § 12-51-100(2000).
. The County failed to provide the delinquent taxpayers with proper notice, which led to the tax sale being set aside by the master, and then erroneously refunded the purchase price to the delinquent taxpayers instead of the successfully bidder.
