Before CORRIGAN, C.J., and GRIFFIN and HOEKSTRA, JJ.
GRIFFIN, Judge.
This case is before us as on leave granted pursuant to a remand from the Supreme Court. Bergeron v. Busch, 453 Mich. 946, 557 N.W.2d 307 (1996). Defendants appeal the order of the lower court denying their motion for summary disposition pursuant to MCR 2.116(C)(7) and for reconsideration. We affirm.

I
The present action was filed in the Oakland Circuit Court and was one of two suits pending against defendants arising out of alleged erroneous investment advice. The case at issue sought relief under various state common-law theories, state securities fraud statutes, the Michigan Consumer Protection Act, and the Racketeer Influenced and Corrupt Organizations Act (RICO). Plaintiffs simultaneously filed a second action in the federal district court seeking recovery *126 under the Employee Retirement Income Security Act (ERISA), as well as federal securities fraud statutes. Defendants removed the state court action to the federal court on the basis of federal question jurisdiction under the RICO. The two cases were thereafter treated as consolidated in federal court, although no formal order of consolidation was entered. Subsequently, pursuant to the parties' stipulation, the federal and state securities fraud claims and the RICO claims were dismissed with prejudice. Defendants then moved for summary judgment with regard to the remaining claims and prevailed with respect to the ERISA claim. However, finding that there was no federal preemption, the federal court declined to exercise supplemental jurisdiction over the state-law claims, denied defendants' motion to dismiss without prejudice the state-law claims, and granted plaintiffs' motion to remand the state-law claims to the Oakland Circuit Court for adjudication.
After remand, defendants moved to dismiss the state court action on the basis of res judicata. The trial court denied defendants' motion, holding that because the federal court did not rule on the state-law claims, there was no prior adjudication on the merits. The sole issue on appeal is whether the trial court erred in denying defendants' motion under MCR 2.116(C)(7) to dismiss on the basis of the doctrine of res judicata.

II
The applicability of res judicata is a legal question that this Court reviews de novo. Board of County Road Commissioners for the County of Eaton v. Schultz, 205 Mich.App. 371,375,521 N.W.2d 847 (1994). Michigan has adopted a broad application of res judicata that bars claims arising out of the same transaction that plaintiff could have brought but did not. Jones v. State Farm Mut. Automobile Ins. Co., 202 Mich.App. 393, 401, 509 N.W.2d 829 (1993). The doctrine serves a two-fold purpose: to ensure the finality of judgments and to prevent repetitive litigation.[1] However, in order for the first action to bar the second, res judicata requires that (1) the prior action was decided on the merits, (2) the matter contested in the second case was or could have been resolved in the first, and (3) both actions involved the same parties or their privies. Energy Reserves, Inc. v. Consumers Power Co., 221 Mich.App. 210, 215, 561 N.W.2d 854 (1997); Board of County Road Commissioners for the County of Eaton, supra.
As a preliminary matter, we are convinced in this case that the requisite similarity in the identity of the parties and claims in the state and federal proceedings is evident from a thorough review of the record. Both the state and federal complaints are based on identical factual allegations arising out of the same transactions and involving the same parties. Both lawsuits are the result of alleged erroneous financial advice that occurred during the same time frame and involved essentially the same assets and investments. The only cognizable difference between the lawsuits are the theories of relief.
We initially note that no federal rule prohibited plaintiffs from filing the two actions involved in this case. Unlike MCR 2.203(A)(1), the federal court rules do not require a plaintiff in federal court to assert all claims arising out of the same transaction in one action. F.R. Civ. P. 18(a). Nevertheless, a plaintiff's ability to split his cause of action is limited by the doctrine of claim preclusion/res judicata. See J Z G Resources, Inc. v. Shelby Ins. Co., 84 F.3d 211 (C.A.6, 1996) (successive federal actions); Cemer v. Marathon Oil Co., 583 F.2d 830 (C.A.6,1978) (federal action followed by state action removed to federal court); Norman Tobacco & Candy Co. v. Gillette Safety Razor Co., 295 F.2d 362 (C.A.5, 1961) (parallel federal actions); see, generally, 6A Wright & *127 Miller, Federal Practice & Procedure (2d ed.), § 1582, p. 525. Thus, the instant case turns on how we treat the federal court's pendent jurisdiction over state-law claims for purposes of res judicata. This Court has considered the res judicata effects of the federal court's pendent jurisdiction on two occasions, in King v. Michigan Consolidated Gas Co., 177 Mich.App. 531, 442 N.W.2d 714 (1989), and Brownridge v. Michigan Mut. Ins. Co., 115 Mich.App. 745, 750-751, 321 N.W.2d 798 (1982).
In King, supra, the plaintiff filed an action in state court alleging racial discrimination in violation of state and federal civil rights statutes and breach of contract. The defendant removed the action to federal court, which declined to exercise pendent jurisdiction over the state-law claims and remanded them back to the state court. Following a trial, a federal jury returned a verdict of no cause of action with respect to the federal claim. The state court then granted the defendant's motion for summary disposition, ruling that the state civil rights claim was barred by res judicata. On appeal, this Court held that the doctrine of res judicata did not preclude adjudication of the plaintiff's state civil rights claim in the state court:
Since plaintiff's state Civil Rights Act claim was not decided on the merits and was not dismissed with prejudice by the federal court, that claim should not be barred by the doctrine of res judicata. The federal court's decision in declining to exercise jurisdiction over the pendent state law claims in this case did not constitute an adjudication on the merits and should not create a situation in which the plaintiff's remanded state claims may be barred by the doctrine of res judicata. In this case, plaintiff did not split his causes of action and prudently raised all of his claims in one complaint. Accordingly, we find that the doctrine of res judicata is not applicable under the facts of this case and that the trial court erred in holding that plaintiff's state Civil Rights Act claim was barred by res judicata. [King, supra at 536, 442 N.W.2d 714.]
In contrast to the plaintiff in King, supra, plaintiffs in the instant case did split their cause of action. Although the federal court treated the instant plaintiffs' federal and state cases as consolidated and rendered one order encompassing both actions, the act of consolidation alone does not preclude the application of res judicata. Consolidation is permitted "as a matter of convenience and economy in administration, but does not merge the suits into a single cause, or change the rights of the parties, or make those who are parties in one suit parties in another." Johnson v. Manhattan R Co, 289 U.S. 479, 496-497, 53 S.Ct. 721, 727-728, 77 L.Ed. 1331 (1933). See also Beil v. Lakewood Engineering & Mfg. Co., 15 F.3d 546, 551 (C.A.6, 1994); Kraft, Inc. v. Local Union 327, Teamsters, 683 F.2d 131, 133 (C.A.6, 1982); State Mut. Life Assurance Co. of America v. Deer Creek Park, 612 F.2d 259, 267 (C.A.6, 1979); People ex rel MacMullan v. Babcock, 38 Mich.App. 336, 342-343, 196 N.W.2d 489 (1972). Accordingly, King is factually distinguishable.
Brownridge, supra, is the second decision of our Court to address the res judicata effects of the federal court's pendent jurisdiction. In Brownridge, the plaintiff commenced an action in federal court for discrimination under federal law. The plaintiff ultimately stipulated the court's dismissal of her claim with prejudice. A week before the federal court entered the final order, the plaintiff commenced an action in state court for wrongful discharge. Applying Michigan's broad rule of res judicata, this Court held that res judicata barred the claim because it arose out of the same transaction as the federal discrimination claim. This Court determined that the plaintiff could have asserted the wrongful discharge claim in the federal action because the federal court could have exercised pendent jurisdiction over it. This Court declined to speculate whether the federal court would have actually exercised jurisdiction, reasoning that the plaintiff's failure to assert the claim in the federal action deprived the federal court of the opportunity to exercise its discretion to hear the state-law claim. Brownridge, supra at 748-749, 321 N.W.2d 798.
The federal court in the instant case, contrary to the situation in Brownridge, had the *128 opportunity to exercise its discretion and in fact did so, choosing to decline to exercise pendent jurisdiction over the state-law claims because the federal basis for the lawsuit no longer existed. Thus, like King, supra, the Brownridge decision is factually distinguishable from the present circumstances.
In our view, the Restatement Judgments, 2d provides the best legal position on this issue. The present situation is squarely addressed by comment e and illustration 10 of the Restatement Judgments, 2d,§ 25, pp. 213-214:
e. State and federal theories or grounds. A given claim may find support in theories or grounds arising from both state and federal law. When the plaintiff brings an action on the claim in a court, either state or federal, in which there is no jurisdictional obstacle to his advancing both theories or grounds, but he presents only one of them, and judgment is entered with respect to it, he may not maintain a second action in which he tenders the other theory or ground. If however, the court in the first action would clearly not have had jurisdiction to entertain the omitted theory or ground ( or, having jurisdiction, would clearly have declined to exercise it as a matter of discretion), then a second action in a competent court presenting the omitted theory or ground should be held not precluded....
* * * * * *
10. A commences an action against B in a federal court for treble damages under the federal antitrust laws. After trial, judgment is entered for the defendant. A then seeks to commence an action for damages against B in a state court under the state antitrust law grounded upon substantially the same business dealings as had been alleged in the federal action. Even if diversity of citizenship between the parties did not exist, the federal court would have had "pendent" jurisdiction to entertain the state theory. Therefore unless it is clear that the federal court would have declined as a matter of discretion to exercise that jurisdiction (for example, because the federal claim, though substantial, was dismissed in advance of trial), the state action is barred. [Emphasis added.]
The comment and illustration are derived from United Mine Workers v. Gibbs, 383 U.S. 715, 725-727, 86 S.Ct. 1130, 1138-1139, 16 L.Ed.2d 218 (1966), in which the Court stated:
Pendent jurisdiction ... exists whenever there is a [federal] claim ... and the relationship between that claim and the state claim permits the conclusion that the entire action before the court comprises but one ... "case." The federal claim must have substance sufficient to confer subject matter jurisdiction on the court. The state and federal claims must derive from a common nucleus of operative fact ... such that he [the plaintiff] would ordinarily be expected to try them all in one judicial proceeding....
[Pendent jurisdiction] need not be exercised in every case in which it is found to exist. It has consistently been recognized that pendent jurisdiction is a doctrine of discretion, not of plaintiff's right.... Certainly, if the federal claims are dismissed before trial, even though not insubstantial in a jurisdictional sense, the state claims should be dismissed as well. Similarly, if it appears that the state issues substantially predominate, whether in terms of proof, of the scope of the issues raised, or of the comprehensiveness of the remedy sought, the state claims may be dismissed without prejudice and left for resolution to state tribunals. [Citations omitted.]
The federal court's pendent jurisdiction is discretionary, and the federal court should "consider and weigh in each case, and at every stage of the litigation, the values of judicial economy, convenience, fairness, and comity in order to decide whether to exercise jurisdiction over a case brought in that court involving pendent state-law claims." Carnegie-Mellon Univ. v. Cohill, 484 U.S. 343, 350, 108 S.Ct. 614, 619, 98 L.Ed.2d 720 (1988). Where the court dismisses all the federal claims before trial, the court normally should decline to exercise jurisdiction over the state-law claims and dismiss them. Id. 108 S.Ct. at 619, n. 7, 484 U.S. at 350, n. 7 and accompanying text. In lieu of dismissal, however, *129 the court may remand to the state court a removed case involving pendent claims. Id. 108 S.Ct. at 623, 484 U.S. at 357. In most cases, remand is preferable to dismissal for the sake of judicial economy. Id.; Lee v. City of Beaumont, 12 F.3d 933, 937 (C.A.9, 1993). Of course, the federal court may in some cases retain jurisdiction over state claims. See Lee, id. at 937.
We are persuaded by and hereby adopt the Restatement position with regard to this issue because it best accounts for the discretionary nature of pendent jurisdiction. The federal court's continuing duty to review throughout the litigation whether to exercise pendent jurisdiction stems from the doctrine's underpinningsjudicial economy and comity. Carnegie-Mellon, 108 S.Ct. at 618-619, 484 U.S. at 349-350. The Restatement approach gives due deference to the comity aspect of the federal court's pendent jurisdiction because, if not for the federal question involved, the state-law claims would not fall within the federal court's jurisdiction and res judicata would not bar a subsequent state court action asserting the claims.
Consistent with Gibbs and the Restatement, most state and federal courts have held that when the federal claim in a federal action is dismissed before trial and it is clear that the federal court would have declined to exercise jurisdiction over a related state claim that could have been raised in the federal action through pendent jurisdiction, a subsequent action in state court on the state claim that would have been dismissed without prejudice in the prior federal action is not barred by the doctrine of res judicata. See, e.g., Parks v. City of Madison, 171 Wis.2d 730, 492 N.W.2d 365 (1992) (and cases cited therein); Sattler v. Bailey, 184 W.Va. 212, 400 S.E.2d 220 (1990) (and citations therein); Merry v. Coast Community College Dist., 97 Cal.App.3d 214, 158 Cal.Rptr. 603 (1979). See, generally, Note, The res judicata implications of pendent jurisdiction, 66 Cornell L.R. 608 (1981).[2] We adopt this rule and, pursuant to it, affirm the decision of the lower court. Plaintiff's state-law claims are not barred by res judicata.
Affirmed.
CORRIGAN, C.J., concurred.
HOEKSTRA, Judge (dissenting).
I respectfully dissent.
The majority opinion sets forth the three requirements of res judicata. That two of the three have been met is not disputed. First, the state and federal suits shared the same parties and privities. Second, the dismissal of the federal claims by the federal court constituted a ruling on the merits. The analysis in this case turns on the remaining third requirement, i.e., whether the claims raised in the state litigation were or could have been resolved in the federal litigation. The precise issue in this case requires us to determine the preclusive effect of a federal court summary judgment rejecting a plaintiff's federal claim on the plaintiff's subsequent state court action to enforce related state claims.
As a threshold matter, I note my areas of agreement with the majority. The majority correctly decides that the federal claims and the state claims arise out of the same factual transaction. The majority also correctly *130 demonstrates that plaintiffs could have tried all their claims in the federal court, although no federal rule of civil procedure prohibited plaintiffs from filing two actions. Last, the majority correctly finds no merit in plaintiffs' argument about consolidation, which was that the doctrine of res judicata did not apply to this case because the dismissal of the federal claim was actually only a partial dismissal of a single action.[1]
I believe that the proper legal conclusion to draw from the facts in this case is that the lower court erred in denying defendants' motion for summary disposition because the dismissal of plaintiffs' federal action with prejudice, which was a suit separate from the state action, requires dismissal of the state action by operation of the doctrine of res judicata. This Court in Brownridge v. Michigan Mut. Ins. Co., 115 Mich.App. 745, 321 N.W.2d 798 (1982), reached a similar conclusion where the plaintiff commenced an action against the defendant in both federal and state courts. See also Carter v. Southeastern Michigan Transportation Authority, 135 Mich.App. 261, 263,351 N.W.2d 920 (1984); Ingham Co. Employees' Ass'n v. Ingham Circuit Court, 170 Mich.App. 118,122, 428 N.W.2d 7 (1988). In Brownridge, supra at 748, 321 N.W.2d 798, both of the plaintiff's actions arose out of the same transaction, involved points that properly belonged to the subject of the litigation, and involved the same matter in issue. Emphasizing the origins of the plaintiff's claims, this Court stated that it saw no reason why the existence of the federal court's discretion in exercising pendent jurisdiction over the plaintiff's state claims should limit the res judicata effect of a federal judgment where the plaintiff had not given the federal court an opportunity to exercise its jurisdiction. Id. at 749,321 N.W.2d 798.
Here, too, plaintiffs failed to give the federal court an opportunity to exercise jurisdiction over both its federal and state-law claims. Instead, plaintiffs chose to split their cause of action and file two separate complaints, one in federal court and one in state court, thereby creating multiple litigation from the same operative facts. Therefore, on the principles espoused in Brownridge, this Court should find that application of the doctrine of res judicata in this case bars plaintiffs' claims in state litigation because the state claims could have been resolved in the federal litigation. However, the majority declines to follow the holding in Brownridge, despite conceding that plaintiffs' two suits arose from the same factual transaction, that plaintiffs' two suits could have been joined in one federal action, and that plaintiffs' two suits retained their individual character at the federal level. Indeed, the majority appears to overrule this Court's holding in Brownridge without explicitly stating so.
The majority instead attempts to fit this case within an exception to the doctrine of res judicata found in the Restatement Judgments, 2d. Specifically, the majority relies on a caveat within comment e to § 25 of the Restatement, which states that a second action is not precluded by operation of the doctrine of res judicata where the court having jurisdiction of the first action would clearly have declined to exercise jurisdiction over the second as a matter of discretion. For support, the majority quotes the Supreme Court's language on pendent jurisdiction in United Mine Workers v. Gibbs, 383 U.S. 715, 725-727, 86 S.Ct. 1130, 1138-1140, *131 16 L.Ed.2d 218 (1966), and cites a line of cases from other state courts deciding what facts will satisfy the determination that the court in the first action would "clearly have declined" to exercise jurisdiction over the entire cause of action, see Parks v. City of Madison, 171 Wis.2d 730, 492 N.W.2d 365 (1992); Sattler v. Bailey, 184 W.Va. 212, 400 S.E.2d 220 (1990); Merry v. Coast Community College Dist., 97 Cal.App.3d 214, 158 Cal.Rptr. 603 (1979).
Like the majority in this case, these state courts interpret the caveat to mean that it is "clear" that a federal court would have declined pendent jurisdiction over a state claim when the federal court decides the federal claim by summary judgment. Parks, supra at 739, 492 N.W.2d 365; Sattler, supra at 218-219, 400 S.E.2d 220; Merry, supra at 225-227, 158 Cal.Rptr. 603. Moreover, this line of cases holds that res judicata would not bar a subsequent state action even where the plaintiff did not seek the federal court's pendent jurisdiction over the state claim, which is what occurred in this case. Parks, supra at 739, n. 4, 492 N.W.2d 365; Sattler, supra at 218-219, 400 S.E.2d 220; Merry, supra at 226-230, 158 Cal.Rptr. 603. With little discussion of the "clarity" ostensibly required by the Restatement in this case, the majority therefore concludes in this case that application of the doctrine of res judicata does not bar litigation of plaintiffs' state claims because the federal judge dismissed the federal action.
I am unpersuaded by the majority's reliance on this interpretation of the caveat in comment e. In my opinion, the majority's interpretation depends on the precarious proposition that the decision of the federal judge to dismiss plaintiffs' federal claims and decline supplemental jurisdiction of plaintiffs' state claims "clearly" indicates that the federal court would not have jointly resolved plaintiffs' state and federal issues had they been originally filed as one suit in the federal court. In contrast, I perceive no factual basis upon which to believe that, at the outset of this litigation, plaintiffs' decision to file separate lawsuits in the state and federal courts was predicated upon a belief that the federal court would decline to exercise jurisdiction over their state-law claims. Here, the federal court unhesitatingly assumed jurisdiction when defendants petitioned for removal of plaintiffs' separately filed state claims. Only after all the federal claims had been resolved by either voluntary dismissal or summary disposition did the federal court decline supplemental jurisdiction over plaintiffs' state claims and order them remanded to the state court.
Other courts have likewise been critical of this interpretation of the caveat in comment e. Specifically, courts have found the interpretation unworkable because it requires a court to engage in "speculative gymnastics," Nwosun v. General Mills Restaurants, Inc., 124 F.3d 1255, 1258 (C.A.10, 1997), "pure speculation," Gilles v. Ware, 615 A.2d 533, 541 (D.C.App., 1992), or "prognosticative futility," Anderson v. Phoenix Investment Counsel of Boston, Inc., 387 Mass. 444, 451, 440 N.E.2d 1164 (1982). The District of Columbia Court of Appeals emphasized that "[a] federal court is not obliged automatically to dismiss a pendent state claim if it grants summary judgment on a federal claim." Gilles, supra at 541. The court also pointed out the inherently contradictory concept of "predicting that a court will `clearly' decline to do something that is a matter of `discretion.' " Id. Similarly, the majority relies on the holding in Gibbs, 86 S.Ct. at 1139, 383 U.S. at 726 where the Supreme Court stated, "[c]ertainly, if the federal claims are dismissed before trial, even though not insubstantial in a jurisdictional sense, the state claims should be dismissed as well." However, the Supreme Court has since clarified this statement in Gibbs and held that it "does not establish a mandatory rule to be applied inflexibly in all cases." Carnegie-Mellon Univ. v. Cohill, 484 U.S. 343, 350, n. 7, 108 S.Ct. 614, 619, n. 7, 98 L.Ed.2d 720 (1988).
Indeed, a second line of cases proffers an interpretation of the caveat in comment e different from and more persuasive than the post hoc analysis proposed by the majority. This second line of cases holds that in order to show that the court in the first action would "clearly have declined" to exercise jurisdiction over the whole action, a plaintiff must file the state claim in federal court, *132 invoke the court's pendent jurisdiction, and thus build a record reflecting the court's exercise of discretion over pendent jurisdiction.[2] This interpretation of the caveat is aptly expressed within the reporter's notes to § 25, which state that "in cases of doubt, it is appropriate for the rules of res judicata to compel the plaintiff to bring forward his state theories in the federal action, in order to make it possible to resolve the entire controversy in a single lawsuit." Restatement Judgments, 2d, § 25, p. 228.
Therefore, if plaintiffs wished to preserve their state claims, then they were obligated to plead them in the federal court because there is no reason to believe that it was "clear" at the outset of this litigation that the district court would have declined to exercise pendent jurisdiction over the state claims. F.R. Civ. P. 18; Federated Dep't Stores, Inc. v. Moitie, 452 U.S. 394, 404, 101 S.Ct. 2424, 2431, 69 L.Ed.2d 103 (1981) (Blackmun, J., concurring); Gilles, supra at 543.
The reason for this rule is evident. The rule of res judicata is designed to forestall a plaintiff from getting "two bites at the apple." We cannot countenance a plaintiff's action in failing to plead a theory in a Federal court with the hope of later litigating the theory in a State court because it was possible, or even probable, that the Federal court would have declined to exercise its pendent jurisdiction. Rather, such a plaintiff should plead his State claim in the Federal court and if that court fails to hear the claim the plaintiff may then ordinarily file suit in a State court. [Anderson, supra at 452, 440 N.E.2d 1164.]
I would therefore reject plaintiffs' contention that they were not required to plead related state claims in their federal complaint because defendants subsequently sought removal of the state claims to the federal court and the federal court granted summary judgment with regard to the federal claims.
In essence, my disagreement with the majority stems from a differing opinion about which point in the litigation is relevant to the analysis of the three requirements for applying the doctrine of res judicata. The majority's point of convergence is the federal court's disposition of plaintiffs' claims, whereas I believe the focus should be on the origin of plaintiffs' claims. By focusing its analysis on the federal court's dismissal of plaintiffs' claims, the majority overlooks an important characteristic of the doctrine of res judicata. The doctrine does not apply when a court itself splits a cause of action, either by dismissing a claim without prejudice attributed to the litigant, Wildfong v. Fireman's Fund *133 Ins. Co., 181 Mich.App. 110, 448 N.W.2d 722 (1989), or by declining jurisdiction on a pendent state claim, King v. Michigan Consolidated Gas Co., 177 Mich.App. 531, 442 N.W.2d 714 (1989). Rather, the doctrine applies when the litigant splits the cause of action. See, e.g., Aquatherm Industries, Inc. v. Florida Power & Light Co., 84 F.3d 1388, 1395 (C.A.11,1996).
Ironically, the majority acknowledges the strong public policies at work in this case. In its first footnote, the majority quotes our Supreme Court's statements in Krolik & Co. v. Ossowski, 213 Mich. 1, 7, 180 N.W. 499 (1920), that "[t]he law abhors multiplicity of suits" and that "[a]ttempts to split a claim into separate causes of action have often met with disfavor." It cannot be disputed that plaintiffs in this case split their cause of action, even though, by exercising reasonable diligence, plaintiffs could have brought all issues arising from the allegedly erroneous investment advice in a single proceeding. This result is precisely what the doctrine of res judicata seeks to avoid. See, e.g., Detroit v. Nortown Theatre, Inc., 116 Mich.App. 386, 323 N.W.2d 411 (1982).
Because all requirements for applying the doctrine of res judicata in this case have been met, I would reverse the order of the trial court and remand for entry of an order dismissing plaintiffs' claims against defendants.
NOTES
[1]  As noted in Krolik & Co. v. Ossowski, 213 Mich. 1, 7, 180 N.W. 499 (1920): "The law abhors multiplicity of suits. Attempts to split a claim into separate causes of action have often met with disfavor." See also Rogers v. Colonial Federal Savings & Loan Ass'n, 405 Mich. 607, 275 N.W.2d 499 (1979); Loud v. General Builders Supply Co., 249 Mich. 331, 228 N.W. 715 (1930); Ginsburg v. McBride, 248 Mich. 221, 226 N.W. 873 (1929); Carter v. Southeastern Michigan Transportation Authority, 135 Mich.App. 261, 263, 351 N.W.2d 920 (1984); Eyde v. Charter Township of Meridian, 118 Mich.App. 43, 50, 324 N.W.2d 775 (1982).
[2]  The Restatement approach does not encourage the practice of claims-splitting such as occurred initially in the present circumstances. On the contrary, in most cases, it forces the plaintiff who asserts both federal and state claims to choose one forum carefully because the plaintiff has a difficult task in showing that the federal court would not have exercised pendent jurisdiction in a case where the court entered judgment after trial:

When the plaintiff fully litigates his federal claim in federal court, that court clearly has the power to hear a closely related pendent claim and will usually choose to exercise pendent jurisdiction. Unless the plaintiff can persuade the state court that the federal court would have declined pendent jurisdiction because of the importance of the state claim or because of possible jury confusion, the state court must bar him from bringing a second action. Although courts will not always exercise their discretion to hear a pendent claim, the Restatement Second forces the plaintiff to assert his state claim in federal court, or risk forfeiting his right to pursue it in any other forum. [66 Cornell L.R., supra at 618.]
Moreover, even where the federal court disposes of the federal claims before trial, collateral estoppel may bar the plaintiff from relitigating factual issues in a subsequent state action.
[1]  Arguably, consolidation never occurred in this case because no formal order of consolidation was entered in the federal case as required by F.R. Civ. P. 42(a). However, even assuming that consolidation occurred because the proceedings in the federal court were consistent with consolidation, federal courts have consistently held that consolidation does not merge separate lawsuits. No Michigan case addresses whether consolidation merges two individual causes of action, but the language of the Michigan court rule on consolidation, MCR 2.505, is indistinguishable from the federal rule, F.R. Civ. P. 42(a). Therefore, the reasoning of the federal rule logically applies with equal force to consolidation issues raised in state litigation. See 3 Martin, Dean & Webster, Michigan Court Rules Practice, pp. 80-81. In addition to the cases cited by the majority for this proposition, see also Red Lake & Pembina Bands v. Turtle Mountain Band of Chippewa Indians, 173 Ct.Cl. 928, 355 F.2d 936, 938, n. 8 (1965) (noting that consolidation does not cause actions to lose their separate identity), and Zdanok v. Glidden Co., Durkee Famous Foods Div., 327 F.2d 944, 950, n. 6 (C.A.2, 1964) (same). Accordingly, neither defendants' removal of the state action to the federal court nor the federal court's subsequent de facto consolidation of the two actions effaces the individual nature of plaintiffs' separately filed federal and state lawsuits.
[2]  See Nwosun, supra at 1258 ("We are persuaded that uncertainty over whether a federal court would have exercised pendant jurisdiction does not justify a conclusion that a plaintiff was denied a full and fair opportunity to litigate a claim."); Gilles, supra at 541; Reeder v. Succession of Palmer, 623 So.2d 1268, 1274 (La., 1993) ("In view of the breadth of the federal trial courts' discretion and the necessary indeterminancy of the discretionary standards, in order for a subsequent court to say that a federal district court clearly would have declined its jurisdiction of a claim not filed, the subsequent court must find that the previous case was an exceptional one which clearly and unmistakably required declination. The rules do not countenance a plaintiff's action in failing to plead a theory in a federal court with the hope of later litigating the theory in a state court as a second string to his bow."); Anderson, supra at 1169 (holding that it is not enough that federal court possibly or probably would have dismissed the pendent state claims); Hayes v. Town of Orleans, 39 Mass.App.Ct. 682, 686, 660 N.E.2d 383 (1996) ("Their voluntary choice of timing and their failure to amend cannot be permitted to subvert the strong policy underlying the doctrine of res judicata."); Blazer Corp. v. New Jersey Sports & Exposition Authority, 199 N.J.Super. 107, 112, 488 A.2d 1025 (1985) (holding that a plaintiff who does not raise state claims in a federal court action will be barred from thereafter asserting them in state court); Rennie v. Freeway Transport, 294 Or. 319, 327, 656 P.2d 919 (1982) ("We are convinced that the better rule, the one more consonant with the policies behind res judicata, is that a plaintiff must attempt to have all claims against a defendant arising out of one transaction adjudicated in one court in one proceeding, at least insofar as possible, despite the fact that the various claims may be based on different sources of law."); Mohamed v. Exxon Corp., 796 S.W.2d 751, 756-757 (Tex.App., 1990) (holding that when no effort was made to present state claims to federal court, state court must presume that federal judgment is res judicata). For a reverse set of facts, see also Heyliger v. State Univ. & Community College System of Tennessee, 126 F.3d 849, 854 (C.A.6, 1997) (citing comment e as authority for holding that pursuant to doctrine of claim preclusion, the plaintiff's earlier Title VII suit in state court bars him from bringing a subsequent title VII action in federal court).
