*455 OPINION

We granted allowance of appeal in this matter to determine whether the Superior Court erred in holding that the legislature’s amendment of the Pennsylvania Corrupt Organizations Act (Pa.C.O.A.), 18 Pa.C.S. § 911 et seq., to include wholly illegitimate enterprises, applied to criminal activity that occurred under the Act in effect prior to the amendment, which this Court interpreted as applying solely to legitimate enterprises in Commonwealth v. Besch, 544 Pa. 1, 674 A.2d 655 (1996). For the reasons that follow, we find that the Superior Court erred. Accordingly, we reverse its decision.

Appellant was found guilty by a jury of single counts of possession of a controlled substance, possession with intent to deliver a controlled substance, delivery of a controlled substance, criminal conspiracy, corrupt organizations and corrupt organizations (conspiracy). He was sentenced to a term of imprisonment of forty-eight to ninety-six months for delivery of a controlled substance and concurrent terms of twenty-seven to sixty months for each of the conspiracy and corrupt organization convictions.1

Appellant appealed the judgment of sentence to the Superi- or Court. While his appeal was pending, this Court issued its decision in Besch, where we interpreted the applicable Pa. C.O.A. as not encompassing the prosecution of wholly illegitimate enterprises. Accordingly, Appellant argued that because the charges relating to his corrupt organization convictions stemmed solely from the government’s allegation of his participation in a wholly illegitimate drug enterprise, his convictions could not stand.2 The Superior Court rejected this argument, noting that

[i]f Besch were the last relevant pronouncement concerning the scope of the corrupt organizations statute, we would be *456constrained to reverse appellant’s conviction. It is not. Within two weeks after the Besch decision, the Pennsylvania legislature amended the statute, and in so doing expressed its disagreement with the supreme court’s ruling.[3] The legislature stated that it never intended to exempt illegal or illegitimate businesses from the reach of the Act.

Shaffer, 696 A.2d at 183. Former Senator Michael Fisher explained the House of Representatives’ motive in seeking to amend the Pa.C.O.A.. He stated before the Senate:

[B]ut most importantly, Mr. President, the House of Representatives, in the action which they took on April 30, added amendments to that bill in an attempt to overrule the decision of the majority, the four person majority of the Pennsylvania Supreme Court on April 17.

S.B. 1172, 180 th Legis.; Pa. Legis. Journal No. 36, at 2028 (June 5,1996) (emphasis added).

The Superior Court found the foregoing legislative action controlling regarding the interpretation to be given the Pa. C.O.A. Moreover, because prior decisions of the Superior Court, and one non-precedential opinion of this Court, had interpreted the Pa.C.O.A. in accordance with the legislature’s subsequently stated intent, the Superior Court concluded that our decision in Besch had no effect on its determination. See id., 696 A.2d at 182, citing Commonwealth v. Yacoubian, 339 Pa.Super. 413, 489 A.2d 228 (1985), and Commonwealth v. Wetton, 537 Pa. 100, 641 A.2d 574, 579 n. 5 (1994) (Zappala, J., Opinion in Support of Reversal, wherein Yacoubian was cited to with approval in dicta). Yacoubian, where the Superior Court held that Pennsylvania’s racketeering act could be read broadly enough to encompass illegitimate as well as legitimate “enterprises” and rejecting the argument that the preamble limited application of the statute to legitimate entities, was overruled in Besch.

*457While the Superior Court recognized a duty to maintain and effectuate the decisional law of this Court, given the legislature’s stated intent contrary to our interpretation in Besch, the court concluded that

to apply the rationale of Besch in disposing of the instant case would be to ignore the intent of the legislature, despite the Besch court’s belief that it correctly had discerned and applied same[,]

Shaffer, 696 A.2d at 183. By its holding, the Superior Court treated the legislature’s action as effectively overruling Besch.

We must now decide what effect, if any, the legislature’s subsequent amendment of the Pa.C.O.A. had on our prior decision in Besch since, as noted by the Superior Court, “[i]f Besch were the last relevant pronouncement,” Appellant’s conviction would be reversed.4

Appellant was charged with and convicted of violating the same provisions of the Pa.C.O.A. as the appellant in Besch. These sections, 18 Pa.C.S. §§ 911(b)(3) & (4), provide:

(3) It shall be unlawful for any person employed by or associated with any enterprise to conduct or participate, directly or indirectly, in the conduct of such enterprise’s affairs through a pattern of racketeering activity.

(4) It shall be unlawful for any person to conspire to violate any of the provisions of paragraph (1), (2) or (3).

The Pa.C.O.A. defined “enterprise” as

any individual, partnership, corporation, association or other legal entity, and any union or group of individuals associated in fact although not a legal entity, engaged in commerce.

18 Pa.C.S. § 911(h)(3).

Whether Appellant could properly be charged and convicted under the foregoing provisions of the Pa.C.O.A. in effect at the time his criminal activity occurred depended upon whether the *458Pa.C.O.A. embraced wholly illegitimate enterprises. Once the legislature finished its efforts, and the Pa.C.O.A. was signed into law, it was for the Courts, ultimately this Court, to interpret the legislative language. We did so in Besch.

After examining the extensive and specific preamble to the Pa.C.O.A., this Court concluded

[tjhere is no escaping the clear intent of this statute. The General Assembly went to great pains to set forth the parameters of this piece of legislation. Pa.C.O.A. is directed at preventing the infiltration of legitimate business by organized crime in order to promote and protect legitimate economic development within Pennsylvania. Although the Commonwealth acknowledges this to be the precise intent of the General Assembly in enacting Pa.C.O.A., they choose to ignore same. However, once the intent of the General Assembly has been ascertained that intent cannot be ignored, rather, it must be given effect.

Besch, 674 A.2d at 659 (citations omitted).

Thus, based upon our interpretation, the applicable Pa.C.O.A. that Appellant was convicted of violating did not apply to wholly illegitimate enterprises. See Harry C. Erb, Inc. v. Shell Construction Co., 206 Pa.Super. 388, 213 A.2d 383 (1965), citing City of Philadelphia v. Schaller, 148 Pa.Super. 276, 25 A.2d 406 (1942) (judicial construction of a statute becomes part of the legislation from the time of its enactment); see also Commonwealth v. Peters, 453 Pa. 615, 306 A.2d 901 (1973) (per curiam order of this Court noting that our decision interpreting Pa.R.Crim.P. 118 was the law in this Commonwealth after the effective date of the rule).

Although the legislature amended the act to state a different meaning of “enterprise” as follows:

(3) ‘Enterprise’ means any individual, partnership, corporation, association or other legal entity, and any union or group of individuals associated in fact although not a legal entity, engaged in commerce and includes legitimate as well as illegitimate entities and governmental entities.

*45918 Pa.C.S. § 911(h)(3), as amended, June 19, 1996, immediately effective (emphasis added), the amendment could only be applied prospectively. Section 1953 of the Statutory Construction Act, entitled “Construction of amendatory statutes,” provides:

Whenever a section or part of a statute is amended, the amendment shall be construed as merging into the original statute, become a part thereof, and replace the part amended, and the remainder of the original statute and the amendment shall be read together and viewed as one statute passed at one time; but the portions of the statute which were not altered by the amendment shall be construed as effective from the time of their original enactment, and the new provisions shall be construed as effective only from the date when the amendment became effective.

1 Pa.C.S. § 1953 (emphasis added). Moreover, amendatory statutes are to be construed retroactively only if such construction is clearly indicated under the provisions of the statute. Commonwealth v. Scoleri, 399 Pa. 110, 160 A.2d 215, 227 (1960).

The legislature failed to clearly indicate in the amendatory act that the amendment of the Pa.C.O.A. should be applied retroactively. Although the legislative history accompanying the amendment indicated that certain legislators desired to overrule our decision in Besch, the legislature lacked authority to do so. See Commonwealth v. Sutley, 474 Pa. 256, 378 A.2d 780, 784 (1977), citing Greenough v. Greenough, 11 Pa. 489 (1849) (the legislature cannot, by an act of assembly, overrule a judicial decision). Nor can the legislature create retroactive authority by passing “clarifying” legislation. St. Joseph Lead Company and Koppers Company, Inc. v. Potter Township, 398 Pa. 361, 157 A.2d 638, 642 (1959) (“[I]t is elementary that the legislature cannot create authority retroactively simply by passing ‘clarifying’ legislation. The intent of the legislature must be determined as of the time the original act was passed.”)5

*460The Superior Court’s decision, in treating Besch as a nullity based upon the legislature’s subsequent amendment of the Pa.C.O.A., was clearly erroneous. The Superior Court, in essence, reinterpreted the statutory language of the Pa.C.O.A. in a manner that was contrary to our interpretation in Besch. However, as the foregoing makes clear, once this Court interpreted the legislative language contained in the applicable act, our interpretation became a part of the legislation from the date of its enactment. The legislature’s failure to clearly set forth its intent in the original act could only be remedied prospectively by the later amendment. ' Thus, the Superior Court violated its duty to effectuate the decisional law of this Court since our interpretation of the prior enactment controlled the matter.6

As Superior Court erred in affirming Appellant’s convictions based upon Sections 911(b)(3) & (4), 18 Pa.C.S. §§ 911(b)(3) & (4) of the Pa.C.O.A., we now reverse its decision in this regard.

concurring.

I continue to believe that this Court erred when it held in Commonwealth v. Besch, 544 Pa. 1, 674 A.2d 655 (1996), that the legislature intended for the Pennsylvania Corrupt Organizations Act (“the Act”), 18 Pa.C.S. § 911 et seq., to encompass only legitimate businesses enterprises. However, because Besch was the law at the time the Superior Court reviewed the judgment of sentence and I believe that the Superior Court erred in applying the amendments to the Act retroactively, I am constrained to concur in the result reached by the majority.1

In Besch, the majority held that in order to be subject to the Act, the Commonwealth needed to establish that the “enterprise” was connected to a legitimate business; thus, a connection to an illegitimate business, such as a drug cartel, was not covered under the Act. At the time of the majority’s holding, the Act defined “enterprise” as “any individual, partnership, corporation, association, or other legal entity and any union or group of individuals associated in fact although not a legal entity, engaged in commerce.” 18 Pa.C.S. § 911(h)(3) (emphasis added). The plain language of the statute indicated that the legislature intended for the Act to apply to both legitimate and illegitimate activities. Nevertheless, the majority in Besch disagreed.

In ruling that the Act applied to only legitimate enterprises, the majority took a path divergent from the United State Supreme Court, which in United States v. Turkette, 452 U.S. 576, 101 S.Ct. 2524, 69 L.Ed.2d 246 (1981), considered the identical definition of “enterprise” found in the federal Racketeer Influenced and Corrupt Organizations statute, 18 U.S.C. § 1961(4),2 and concluded that:

*462RICO is equally applicable to a criminal enterprise that has no legitimate dimension or has yet to acquire one. Accepting that the primary purpose of RICO is to cope with the infiltration of legitimate businesses, applying the statute in accordance with its terms, so as to reach criminal enterprises, would seek to deal with the problem at its very source.

Id. at 591.3

The majority justified ignoring the plain language of the statute, as well as the United States Supreme Court’s interpretation of the identical language, based on one sentence in the Act’s preamble which states that:

The vast amounts of money and power accumulated by organized crime are increasingly used to infiltrate and corrupt legitimate businesses operating within the Commonwealth, together with all of the techniques of violence, intimidation, and other forms of unlawful conduct through which such money and power are derived.

18 Pa.C.S. § 911(a)(3). From this, the majority in Besch went on to conclude that:

There is no escaping the clear intent of this statute. The General Assembly went to great pains to set forth the parameters of this piece of legislation. Pa.C.O.A. is directed at preventing the infiltration of legitimate business by *463organized crime in order to promote and protect legitimate economic development within Pennsylvania.

544 Pa. at 10, 674 A.2d at 659.

However, two weeks after this Court’s ruling in Besch, the General Assembly acted to correct this Court’s erroneous interpretation by beginning the process to clarify the definition of enterprise under the Act to include both legitimate and illegitimate enterprises.4 At the time of the amendments to the Act, members of both the House of Representatives and the Senate made clear their disagreement with this Court’s interpretation of the Act. For example, State Representative Albert H. Masland stated:

Our Supreme Court, by a four-to-three vote, decided that the Pennsylvania Corrupt Organization’s [sic] Act did not apply to those corrupt organizations who wholly engaged in illegal activities. In other words, they said, a corrupt organization had to also be involved in legitimate business enterprises for that to come under the purview of the Corrupt Organizations Act.... That was not the intent, I do not believe, of this legislature back in 1970 when the act was passed. I do not think it is our intent today, and I think we ought to join with Chief Justice Nix in his dis[s]enting opinion, along with Justices Castille and Sandra Schultz Newman, and change our act so that the rest of the Supreme Court understands what we intend.

Commonwealth v. Shaffer, 696 A.2d 179, 184 (Pa.Super. 1997) (citing Act 55, 180th Legis. (Pa. 1996)) (emphasis added). Moreover, former Senator Michael Fisher (now Attorney General) stated:

... [B]y concurring with the amendments added by the House of Representatives ... we are clarifying that statute to say that, in fact it is our intent that drug organiza*464tions and drug enterprises across Pennsylvania and other illegitimate enterprises across Pennsylvania were intended to be covered by this Statute.

Id. at 185 (citing S.D. 1172, 180th Legis; Pa. Legis. Journal No 36, at p. 2028-29 (June 5, 1996)) (emphasis added). The Senate went on to pass the clarifying amendment to the Act by a unanimous vote. “While statements made by legislators during the enactment process are not dispositive of legislative intent, they may be properly considered as part of the contemporaneous legislative history.” Washington v. Baxter, 553 Pa. 434, 719 A.2d 733, 738 (1998).

Taken together, the legislative comments and the alacrity with which the General Assembly acted following the decision in Besch, provides ample evidence to support the conclusion that the legislature did not intend for the Act to apply only to legitimate enterprises. The majority in Besch erroneously determined the legislature’s intent. It is well established in the Commonwealth that “[t]he failure of the General Assembly to change the law which has been interpreted by the courts creates a presumption that the interpretation was in accordance with the legislative intent.” Fonner v. Shandon, Inc., 555 Pa. 370, 724 A.2d 903, 906 (1999) (citing Commonwealth v. Willson Products, Inc., 412 Pa. 78, 87-88, 194 A.2d 162, 167 (1963)).5 When the General Assembly does act to make clear that the court’s interpretation is inconsistent with its legislative intent, we should follow the guidance of the legislature and, where possible, amend earlier erroneous interpretations. See Commonwealth v. Lassiter, 554 Pa. 586, 722 A.2d 657, 661 n. 3 (1998) (“actions undertaken in subsequent sessions of the Legislature are relevant in interpreting a statute which was passed in a previous session of the Legislature.”)

*465The majority in the instant matter continues to cling to its unsupported belief that prior to the clarifying amendments by the General Assembly, the Act applied only to legitimate enterprises and that the amendments added new crimes applicable under the Act only in the future. That is not what occurred. The General Assembly in obvious disagreement with this Court’s interpretation of the statute, acted to demonstrate to this Court how the Court had erred in trying to determine the General Assembly’s intent that the Act cover illegitimate organizations. The majority in the instant matter is unwilling to cede its error.

Nevertheless, when the Superior Court heard this case, Besch was the law of this Commonwealth. Therefore, it was constrained under the doctrine of stare decisis to interpret the statute as encompassing only legitimate enterprises.6 The Superior Court, as an intermediate appellate court, is obligated to follow and apply the decisions of the Supreme Court of Pennsylvania, even where it disagrees with this Court’s decision. “If a majority of the Justices of this Court, after reviewing an appeal before us ... join in issuing an opinion, [the] opinion becomes binding precedent on the courts of this Commonwealth.” Commonwealth v. Tilghman, 543 Pa. 578, 673 A.2d 898, 903 (1996).

I agree with the majority that the Superior Court’s attempt to justify its decision, affirming the trial court and rejecting Besch based on the subsequent amendments to the Act, is flawed. The problem with the Superior Court’s reasoning is that while the amendments do provide evidence that the majority in Besch failed to accurately ascertain the legislature’s intent, the amendments do not overrule the Besch decision. “It is elementary that the legislature cannot create authority retroactively by passing ‘clarifying’ legislation.” St. Joseph Lead Co. v. Potter, 398 Pa. 361, 368, 157 A.2d 638, 642 (1959). The legislature’s failure to expressly provide that the *466amendments should be applied retroactively prohibit a finding to the contrary by the courts.7 Therefore, I believe that the Superior Court was constrained to follow Besch, however distastefully.

Stare decisis ensures a level of stability and clarity by providing assured guidance as to what the law is.8 Haphazard *467reversals by the judiciary erodes a level of confidence that people place in the court system. Therefore, while I continue to believe that the decision in Besch was wrongly decided, I feel constrained to concur with the result reached by the majority given the absence of a “savings clause” by the legislature applying its amendments to pending cases.
