Popp Telecom, Inc., Washington Sharecom, Inc., Humbird Securities Company, and Northern Securities Company (collectively, the "Dissenters") appeal from the district court's1 entry of summary judgment in favor of American Sharecom, Inc. (the "Corporation"), Steven C. Simon ("Simon"), James J. Weinert ("Weinert"), and William J. King ("King") (collectively, "ASI"). We affirm.

This case makes its second appearance before this court. A detailed account of the events in this case is provided in our prior opinion, Popp Telcom, Inc. v. American Sharecom, Inc., 210 F.3d 928, 931-34 (8th Cir.2000). We provide an abbreviated chronology of the events here.

Simon, Weinert, and the Dissenters were shareholders of the Corporation. Simon, Weinert, and King were the President, Vice President, and Chief Financial Officer, respectively, of the Corporation and also served on its Board of Directors. On April 7, 1992, the Corporation's Board approved a "freeze-out" merger with Sharecom Holdings, Inc., a corporation owned exclusively by Simon and Weinert. To complete the merger, the Corporation had to pay all non-acquiring shareholders the fair value of their shares. Simon and Weinert received no cash proceeds but emerged as the owners of the surviving corporation. The Dissenters opposed the merger and challenged the proffered payment of $17,694.64 per share. The Corporation's shareholders approved the merger by a divided vote on May 8, 1992, and the merger became effective on that date.

Following the merger, the Corporation paid off each shareholder except the Dissenters. The Corporation then filed a petition for determination of value in Hennepin County District Court. The Dissenters filed a counterclaim alleging the merger was invalid due to fraud, but the court dismissed the counterclaim as outside the scope of the valuation proceeding. On June 28, 1994, the court found that the Corporation's stock had been undervalued and that each share was worth $111,893. About five months after the valuation proceeding and over two years after the merger, Rochester Telephone Corporation announced that it would acquire the Corporation for about $190 million worth of Rochester Telephone stock.

On December 16, 1994, the Dissenters moved the Minnesota Court of Appeals to remand the valuation proceeding to state court for reconsideration on the basis of newly discovered evidence that ASI had defrauded the court during the proceeding. However, because a satisfaction of judgment had been entered on the valuation proceeding, the Minnesota Court of Appeals ruled that the state district court lacked jurisdiction to vacate the judgment. See Am. Sharecom, Inc. v. LDB Int'l Corp., 553 N.W.2d 433, 435 (Minn.Ct.App. 1996) ("Sharecom II"). The court noted that the Dissenters had another available remedy in the form of a separate common law fraud action. Id. at 434.

The case now on appeal had its genesis in May of 1994, when the Dissenters served, but did not file, a complaint alleging several claims against ASI, including common law fraud. No suit was filed until the Dissenters filed an amended complaint in state court on November 8, 1996, alleging seven claims.2 ASI removed the case to federal court on December 2, 1996, and the Dissenters filed their second amended complaint.

The district court eventually dismissed or granted summary judgment on all claims. The Dissenters appealed, and we reversed and remanded. See Popp Telcom, 210 F.3d at 944. On remand, the Dissenters filed their third amended complaint.3 The Dissenters later brought a motion to add a claim for punitive damages under Minnesota law. This motion was granted on May 7, 2002.

Briefly stated, the Dissenters' claims are based on their belief that Simon and Weinert used a series of schemes to steal control of the Corporation. The Dissenters claim that Simon and Weinert solicited and defrauded unwitting shareholders into selling their stock at low prices to John Van Heuvelen, a longtime friend of Simon. The Dissenters assert that Van Heuvelen was a "strawman" who was actually purchasing the stock for Simon and Weinert. According to the Dissenters, the low prices in the Van Heuvelen transactions allowed Simon and Weinert to depress the value of the Corporation's stock in later tender offers.

The Dissenters also claim that Simon and Weinert misrepresented the value of the Corporation's shares in their tender offers to other shareholders; used unexercised stock options to dilute the price they told shareholders could be paid for the Corporation; made material misrepresentations in, or omitted material facts from, tender offers in order for the Corporation to redeem stock; made material misrepresentations to financial institutions; and lied under oath and concealed information from the Dissenters and the court during the valuation proceeding.

Following the close of discovery, ASI moved for summary judgment. On March 20, 2003, the district court granted ASI's motion and dismissed all claims. The Dissenters now appeal.

We review the grant of summary judgment de novo, viewing the evidence in the light most favorable to the nonmoving party. See United Fire & Cas. Ins. Co. v. Garvey, 328 F.3d 411, 412-13 (8th Cir. 2003). Summary judgment is appropriate where there is no genuine issue of material fact and the moving party is entitled to judgment as a matter of law. Fed. R.Civ.P. 56(c). Summary judgment is mandated if the nonmoving party fails to establish the existence of an essential element of its case. See Celotex Corp. v. Catrett, 477 U.S. 317, 322, 106 S. Ct. 2548, 91 L. Ed. 2d 265 (1986). "[A] complete failure of proof concerning an essential element of the nonmoving party's case necessarily renders all other facts immaterial." Id. at 323, 106 S. Ct. 2548.

The Dissenters' RICO claim had not been passed upon by the district court when this court first entertained the prior appeal. However, when the first case was remanded, the district court held that the Dissenters' RICO claim was barred by the Private Securities Litigation Reform Act of 1995 ("PSLRA").4 In making this ruling, the district court applied the framework set forth in Landgraf v. USI Film Products, 511 U.S. 244, 114 S. Ct. 1483, 128 L. Ed. 2d 229 (1994), and concluded that application of the PSLRA to the Dissenters' RICO claim would not have retroactive effect.5 The district court was guided by the opinions of other courts who have addressed the issue in the context of RICO claims filed after the PSLRA's effective date based on conduct pre-dating the PSLRA. Compare Scott v. Boos, 215 F.3d 940, 945-49 (9th Cir.2000) (holding the PSLRA has retroactive effect when applied to RICO claims filed after the PSLRA's effective date based on conduct occurring prior to the effective date) with Kolfenbach v. Mansour, 36 F. Supp. 2d 1351, 1353-54 (S.D.Fla.1999) (holding, on nearly identical facts, that application of the PSLRA did not have retroactive effect). Relying on the reasoning in Kolfenbach, the district court held that the Dissenters' right to assert their RICO claim expired on the PSLRA's effective date.

Although we agree with the district court's conclusion that the PSLRA bars the Dissenters' RICO claim, we hold that our prior decision in Professional Management Associates, Inc. Employees' Profit Sharing Plan v. KPMG, LLP, 335 F.3d 800 (8th Cir.2003), cert. denied, 540 U.S. 1162, 124 S. Ct. 1176, 157 L. Ed. 2d 1207 (2004) (No. 03-864) (hereinafter "PMA"), is dispositive of the Dissenters' RICO claim. Therefore, we affirm the district court's grant of summary judgment on this claim, but we do so for reasons different from those articulated by the district court.

In PMA, we held that the Securities Litigation Uniform Standards Act of 1998 ("SLUSA") applied to and barred "all actions commenced after its enactment, even if the challenged conduct predate[d] SLUSA." Id. at 804. SLUSA, which was enacted on November 3, 1998, provides for removal to federal court and dismissal of certain class actions brought under state law by any private party alleging "an untrue statement or omission of a material fact in connection with the purchase or sale of a covered security." 15 U.S.C. § 77p(b)(1). The conduct at issue in PMA occurred between 1994 and 1997, but the class action lawsuit was not filed in state court until three years after SLUSA's enactment. PMA, 335 F.3d at 803. The district court concluded that the complaint filed in the case implicitly alleged misrepresentations and omissions in connection with the purchase of a covered security and dismissed the case under SLUSA. Id. at 802.

On appeal, the plaintiffs claimed the district court erred in applying SLUSA retroactively to the pre-enactment conduct. Id. at 803. In affirming the district court, this court concluded that no retroactivity analysis was needed because SLUSA merely established "a procedural rule regarding the filing of class action lawsuits alleging securities fraud." Id. at 803-04. Relying on Landgraf, we pointed out that, generally, there is no retroactivity concern when a new procedural rule becomes effective after a cause of action accrues but before the filing of a lawsuit because procedural rules regulate secondary conduct rather than primary conduct. Id. at 803. Because SLUSA regulated only "secondary conduct, the filing of the lawsuit, not the primary, allegedly illegal pre-enactment conduct[,]" we held that SLUSA applied to all actions commenced after its enactment, even if the conduct occurred before enactment. Id. at 803-04.

There are several similarities between PMA and the instant case. First, the allegedly illegal conduct giving rise to the Dissenters' RICO claim occurred prior to the PSLRA's effective date, but the Dissenters did not amend their complaint to add the RICO claim until after the PSLRA's enactment. Second, SLUSA and the PSLRA both eliminate causes of action. SLUSA eliminates state law securities class actions, and the PSLRA eliminates securities-based RICO claims. Third, neither SLUSA nor the PSLRA eliminate a party's right to pursue other claims. A party who previously could have brought a state law securities class action may bring a class action in federal court under federal law or may pursue his state law claims in state court in an individual action. See Winne v. Equitable Life Assurance Soc'y of the U.S., No. 03 Civ. 1689, 2003 WL 22434215, at *9 (S.D.N.Y. Oct.27, 2003). Similarly, a party who previously could have brought a RICO claim for securities fraud may still pursue a claim under federal securities laws. See Mathews v. Kidder, Peabody & Co., 161 F.3d 156, 164 (3d Cir.1998). Finally, neither SLUSA nor the PSLRA regulate the underlying, allegedly illegal conduct. Like SLUSA, the only relevant conduct regulated by the PSLRA is the filing of a RICO claim.

Based on the foregoing analysis, we conclude the PSLRA, like SLUSA, is merely a procedural rule regulating the filing of a RICO claim.6 We therefore hold that the PSLRA applies to all securities-based RICO claims commenced after its effective date even if such claims are based on conduct which predates the PSLRA. Accordingly, the Dissenters' RICO claim is barred unless it was pending on the date of the PSLRA's enactment. The Dissenters insist their claim falls within this exception.

On appeal, the Dissenters argue the district court should have applied the relation-back doctrine of Fed.R.Civ.P. 15(c)(2)7 to save their RICO claim. Although the events giving rise to the Dissenters' RICO claim arose by June of 1994, the Dissenters did not amend their original complaint to add the RICO claim until November 8, 1996, almost one year after the PSLRA took effect. Despite their apparent tardiness, the Dissenters argue their RICO claim relates back to their original pleading. Therefore, the Dissenters contend, their RICO claim is preserved because their lawsuit was pending at the time of the PSLRA's enactment. See Mathews, 161 F.3d at 171 (holding that the PSLRA does not apply to securities-based RICO claims pending on the date of its enactment).

The district court's application of Rule 15(c) is reviewed for an abuse of discretion. See Mandacina v. United States, 328 F.3d 995, 1000 (8th Cir.2003). Generally, courts apply the relation-back doctrine with reference to statutes of limitations, but it has been applied in other contexts. See Alpern v. UtiliCorp United, Inc., 84 F.3d 1525, 1543 (8th Cir. 1996). However, we are not aware of any cases in which the doctrine has been applied to save a RICO claim first asserted after the PSLRA's enactment. The district court concluded application of the doctrine was not warranted because the Dissenters had no right to expect that their RICO claim would survive any change in the law merely because the conduct underlying the claim had already occurred. See ABF Capital Mgmt. v. Askin Capital Mgmt., L.P., 957 F. Supp. 1308, 1320 (S.D.N.Y.1997) ("[I]t has long been recognized that `no person has a vested right in any general rule of law or policy of legislation entitling him to insist that it remain unchanged for his benefit.'") (quoting Chicago & Alton R.R. v. Tranbarger, 238 U.S. 67, 76, 35 S. Ct. 678, 59 L. Ed. 1204 (1915)). We find no error in the district court's reasoning.8

In summary, because the Dissenters filed their RICO claim after the PSLRA's effective date, the district court did not err in granting summary judgment in favor of ASI on this claim.

The district court granted summary judgment in favor of ASI on the Dissenters' common law fraud claims9 because the Dissenters failed to establish detrimental reliance and lacked standing. On appeal, the Dissenters argue they are entitled to pursue their claims based on the law of the case doctrine or, in the alternative, because they state cognizable claims for common law fraud. We are not persuaded by either argument.

"The law of the case doctrine prevents the relitigation of a settled issue in a case and requires courts to adhere to decisions made in earlier proceedings." Kan. Pub. Employees Ret. Sys. v. Blackwell, Sanders, Matheny, Weary & Lombardi, L.C., 114 F.3d 679, 687 (8th Cir. 1997). Contrary to the Dissenters' assertion, neither our opinion in Popp Telcom, 210 F.3d 928, nor that of the Minnesota Court of Appeals in Sharecom II, 553 N.W.2d 433, decided that the Dissenters had established the requisite elements of a common law fraud claim. These opinions recognized only the Dissenters' right to bring a common law fraud claim, but they never reached or assessed the merits of that claim. See Popp Telcom, 210 F.3d at 939; Sharecom II, 553 N.W.2d at 434.10

The Dissenters also contend they state cognizable common law fraud claims. In order to maintain a common law fraud claim under Minnesota law, a plaintiff must prove: (1) a false representation of material fact that is susceptible of knowledge; (2) made with knowledge that it is false or asserted as if it is based on the person's own knowledge without knowing whether it is true or false; (3) made with the intent to induce another to act in reliance on the representation; and (4) causing the other party to act in reliance to its detriment. See Sharecom II, 553 N.W.2d at 434; Davis v. Re-Trac Mfg. Corp., 276 Minn. 116, 149 N.W.2d 37, 38-39 (Minn.1967). Detrimental reliance is an essential element of a common law fraud claim, and failure to establish detrimental reliance dooms a claim for common law fraud. See Breezy Point Airport, Inc. v. First Fed. Sav. & Loan Ass'n of Brainerd, 288 Minn. 534, 179 N.W.2d 612, 615 (Minn. 1970) ("It is elementary that absent the essential element of reliance, an action for fraud must fail."); Nilsen v. Farmers' State Bank of Van Hook, N.D., 178 Minn. 574, 228 N.W. 152, 153 (Minn.1929) (holding that a plaintiff must show reliance upon false representations to recover).

The Dissenters allege numerous fraudulent activities by Simon and Weinert designed to induce the Corporation's shareholders to sell their shares. However, the Dissenters were not induced to sell their shares by any of the alleged fraudulent activities of Simon and Weinert, a fact they admit. The Dissenters took no action in reliance on any omissions or misrepresentations of material fact by Simon and Weinert prior to the merger. While the evidence supports the allegation that ASI engaged in fraudulent conduct to convince shareholders to sell their shares, the Dissenters never sold their shares. The Dissenters' lack of reliance is further evidenced by their vote against the proposed merger with Sharecom. The Dissenters had no control beyond that vote and eventually were paid fair value for their shares as determined by a judge.11

We conclude the Dissenters cannot establish detrimental reliance, an essential element of their common law fraud claims. Accordingly, we hold that summary judgment in favor of ASI was appropriately granted on these claims.

We find no error in the district court's grant of summary judgment in favor of ASI on this claim. In the present case, ASI obtained the Dissenters' stock through the merger and paid the judicially determined fair value in return. Because ASI paid for what it received, the Dissenters cannot establish an unjust enrichment claim under Minnesota law. See Service-Master of St. Cloud v. GAB Bus., Servs., Inc., 544 N.W.2d 302, 306 (Minn.1996).

2. Breach of Fiduciary Duty and Unfairly Prejudicial Conduct

The district court properly dismissed the Dissenters' breach of fiduciary duty and unfairly prejudicial conduct claims because they are derivative claims belonging to the Corporation. A shareholder asserting a cause of action belonging to the corporation must seek redress "in a `derivative' action on behalf of the corporation rather than in a direct action by the individual shareholder." Northwest Racquet Swim & Health Clubs, Inc. v. Deloitte & Touche, 535 N.W.2d 612, 617 (Minn.1995). The relevant inquiry for determining whether a claim is direct or derivative is "whether the injury to the individual plaintiff is separate and distinct from the injury to other persons in a similar situation as the plaintiff." Id. If the injury is not separate and distinct, only a derivative action is available. See id. Because any injury the Dissenters suffered as a result of Simon and Weinert's alleged breaches of fiduciary duty is not separate and distinct from the injury to other minority shareholders, their breach of fiduciary duty claim is derivative. Further, the Dissenters' unfairly prejudicial conduct claim is based on allegations that the actions of Simon, Weinert, and King constituted waste and misappropriation of corporate assets. However, waste and misappropriation of corporate assets "are traditional derivative claims that rightfully belong to the corporation." Wessin v. Archives Corp., 592 N.W.2d 460, 465 (Minn. 1999).

In order to state a claim under the Minnesota Securities Act, Minn.Stat. § 80A.01, a plaintiff "must allege a misstatement or omission in connection with his own decision to purchase or sell a security." Davis v. Midwest Disc. Sec., Inc., 439 N.W.2d 383, 388 (Minn.Ct.App. 1989). Humbird Securities Company and Northern Securities Company argue on appeal that because they exchanged their stock for value, there was a sale under § 80A.01. However, there is no connection in this case between any alleged fraud or misrepresentation by ASI and some decision by the Dissenters to sell their stock. Rather than deciding to sell their stock, the Dissenters were forced to sell. Although the Dissenters objected to the freeze-out merger, the merger eliminated the Dissenters' ability to make a decision regarding the sale of the stock. As a result, § 80A.01 does not apply and the district court correctly granted summary judgment.

The district court held that the Dissenters could not maintain their claim under the Minnesota Prevention of Consumer Fraud Act ("CFA"), Minn.Stat. §§ 325F.68-325F.70, because they were sellers in this case, and the CFA only protects consumers. On appeal, the Dissenters argue that the CFA is not expressly limited to consumers and applies to any fraud in connection with the sale of merchandise whether such fraud involves the buyer or the seller. We are not persuaded by the Dissenters' argument. Although the CFA should be construed broadly to enhance consumer protection, see Ly v. Nystrom, 615 N.W.2d 302, 308 (Minn. 2000), the Dissenters cite no Minnesota case which has applied the CFA to allow the seller to bring a claim alleging fraud on the part of the consumer. The cases cited by the Dissenters are clearly distinguishable.12 Accordingly, we hold the Dissenters were not consumers protected by the CFA and the district court properly granted summary judgment in favor of ASI on this claim.

5. Civil Liability for Theft and Transfer of Stolen Property

The district court concluded there was no stolen property to support these claims because the Dissenters had no choice but to surrender their shares in the freeze-out merger. We agree. The Dissenters argue that ASI's fraudulent conduct in tricking other shareholders into selling their shares, which eventually allowed ASI to obtain the Dissenters' shares in the freeze-out merger, meets the requirements for theft under Minnesota law. See Minn.Stat. § 609.52, subd. 2(4) (defining theft to include obtaining property or services from another person "by swindling"). However, no theft occurred in this case because the Dissenters sold their shares pursuant to a court-supervised merger. In addition, the Dissenters cannot claim they were swindled out of their shares because they never relied on any of ASI's misrepresentations prior to the merger. In this case, the Dissenters never sold their shares in reliance on any fraudulent representations by ASI. Instead, as we have previously stated, the Dissenters were forced to sell their shares in the freeze-out merger. We conclude the district court did not err in granting summary judgment in favor of ASI on these claims.

For the foregoing reasons, the judgment of the district court is AFFIRMED.
