Martha Poe appeals the District Court’s 1 decisions to affirm an award of costs to defendant in Poe v. John Deere Co., Nо. 78-0578-CV-W-5 (W.D.Mo. Dec. 14, 1981), and to grant defendant’s motion for summary judgment in Poe v. John Deere Co., No. 81-0365-CV-W-5 (W.D.Mo. Oct. 21, 1981) because the suit was barred by res judicata. She contends that the award of costs was improper because the court did not have the. power to tax costs against the plaintiff, and in the alternative that there was an abuse of discretion. She alleges that res judicata does not bar her other suit because: a) a claimant who fails to win on one theory may relitigate her claim on a second theory not raised before; b) she raises two separate and distinct causes of action; and c) the causes of action she raises in her second action could not have been raised before. We affirm.
*1105 On August 7, 1978, Ms. Poe filed suit (“Poe P’) in the District Court alleging that John Deere had discriminated against her on the basis of her race and in retaliation for opposing John Deere’s emрloyment practices, in violation of Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e-5, and the Civil Rights Act of 1866, 42 U.S.C. § 1981. The Court granted John Deere summary judgment on the Title VII claim on February 27, 1980. 2 Trial on the § 1981 claim began on April 27, 1981.
On April 27, 1981, after the jury in Poe I was sworn but before any evidence was presented, Ms. Poe moved for leave to amend her complaint. She wanted to include сlaims for actual and punitive damages under the theories of “prima facie tort,” 3 violation of the Missouri Service Letter Statute, invasion of privacy, injurious falsehood, and intentional infliction of emotional distress. The motion was denied. The jury found in favor of John Deere; the judgment еntered on the verdict was not appealed. On October 29,1981, the Clerk of the District Court entered an order settling costs. The total costs taxed in favor of John Deere amounted to $1,384.91. The Court subsequently denied plaintiff’s motion to review the order.
Ms. Poe filed another suit against John Deere (“Poe IP’) in the Circuit Court of Jackson County, Missouri, on Aрril 27,1981, the same day the trial of Poe I began. She sought the same relief and raised the same theories she had attempted to assert in her amended complaint in Poe I. John Deere removed the case to the District Court because of diversity of citizenship. The District Court granted John Deere’s mоtion for summary judgment on res judicata grounds.
I.
Res Judicata
Federal law governs the issue of res judicata.
Poe II
is in a federal court because it is a diversity case, but the question presented is the effect of the judgment rendered, in
Poe I,
by a federal court on a claim arising under federal law, 42 U.S.C. § 1981. Even if
Poe II
had not been removed from the state court, federal law would still have governed this question. See
Stoll v. Gottlieb,
Plaintiff’s contention that
Poe II
raises theories of recovery not presented in
Poe I
does not enable her to escape the effects of res judicata. Final judgment on the merits precludes the relitigation of a claim on any grounds raised before or on any grounds which could have been raised in the prior action.
Federated Department Stores, Inc.
v.
Moitie,
Plaintiff argues that
Poe I
and
II
raise two separate and distinct claims and that
Poe I
should therefore not be given res
*1106
judicata effect. The parameters of a “clаim” cannot be stated with mathematical precision. For the purpose of determining whether a plaintiff presents two separate claims, we have looked to whether or not proof of the same facts will support both actions, or to whether the wrong for which redress is sought is the same in both actions.
Woodbury v. Porter,
When a valid and final judgment rendered in an action extinguishes the plaintiff’s claim pursuant to the rules of merger or bar . . . the claim extinguished includes all rights of the plaintiff to remedies against the defendant with respect to all or any part of the transaction, or series of connected transactions, out of which the action arose.
Restatement (Second) of Judgments § 24(1) (1982). The term “transaction” connotes a common nucleus of operative facts.
(2) What factual grouping constitutes a “transaction”, and what groupings constitute a “series”, are to be determined pragmatically, giving weight to such consideratiоns as whether the facts are related in time, space, origin, or motivation, whether they form a convenient trial unit, and whether their treatment as a unit conforms to the parties’ expectations or business understanding or usage.
Id.
at § 24(2).

We believe this is the correct approach.
Cf. Brown v. St. Louis Police Department,
Poe I and II present the same claim. They emerge from the samе transaction and share precisely the same nucleus of operative facts. The thrust of both cases is whether Ms. Poe was wrongfully discharged on April 21,1977, or whether, as John Deere contends, she was terminated because of *1107 excessive and inexcusable absenteeism and bеcause she made an unauthorized use of the company’s name. Ms. Poe concedes that both cases involve the same facts and that she would present the same evidence in Poe II as she did in Poe I. Poe II is nothing more than an attempt to apply different legal labels to the facts of Poe I. In her briеf to the District Court in opposition to defendant’s motion for summary judgment (D.R. 126) she says the following: “[T]he fact that the facts and transactions at issue in Poe I are also at issue in this suit does not mean that the two suits involve the same cause of action. The weight to be given certain facts, the nature оf the wrongs asserted, the inferences to be drawn from certain premises, and the conclusion to be drawn from all the evidence are entirely different.” We disagree. A court ruling bars relitigation of actions arising out of the same transaction or factual setting. Her concessiоns are fatal to her cause.
There is no merit to Ms. Poe’s argument that the theories she raises in Poe II were unavailable to her in Poe I because the District Court in Poe I denied leave to amend her complaint. Ms. Poe filed suit August 7,- 1978. She did not move to amend her complaint until April 27, 1981, the first day of trial. It was well within the District Court’s discretion to deny leave under Fed.R.Civ.P. 15(a) beсause the motion was filed too late. We agree with the Restatement (Second) of Judgments § 25 comment b (1982), that “[i]t is immaterial that the plaintiff in the first action sought to prove the acts relied on in the second action and was not permitted to do so because they were not alleged in the complaint and an application to amend the complaint came too late.” Moreover, Ms. Poe could have appealed from the denial of her motion to amend. She did not.
There is equally little merit to Ms. Poe’s contention that the prima faсie tort and service-letter theories were unavailable pri- or to April 27, 1981. Missouri’s service-letter statute, Mo.Ann.Stat. Sec. 290.140 (Vernon 1965) has been in effect since 1905. It provides: “Whenever any employee .. . shall be discharged ... it shall be the duty of the superintendent or manager ... to issue to suсh employee a letter setting forth the nature and character of service rendered .. . and truly stating for what cause, if any, such employee has quit such service.” People have been litigating service-letter claims in Missouri at least since a private cause of action to effectuate the statute was recognized in
Cheek v. Prudential Ins. Co.,
The doctrine of res judicata is a fundamental precept of common-law adjudication. It has the salutary effects of protecting adversaries from the expense and vexa *1108 tion of multiple lawsuits, conserving the limited time of judges, and fostering reliance on decisions of courts. The doctrine of res judicata is meant to preclude precisely the course оf action which plaintiff pursued in Poe I and II.
II.
Costs
In a separate appeal Ms. Poe challenges only the assessment of costs against her following the jury’s verdict in
Poe I
that John Deere did not discriminate against her in violation of 42 U.S.C. § 1981. She does not appeal from the merits of the judgment against her in
Poe I.
John Dеere argues that an award of costs is not appeal-able. The rule is that a party cannot appeal a judgment upon the issue of costs unless the power of the trial court to assess costs is at issue.
Wetzel v. Ohio,
We reject plaintiff’s attempt to invoke the
Christiansburg
standard. Fed.R. Civ.P. 54(d) provides: “Except when express provision therefor is made either in a statute of the United States or in these rules, costs shall be allowed as of course to the prevailing party unless the court otherwise directs ....” We see no reason to prefer civil-rights plaintiffs over some other class of litigants who have claims based on federal statutes. Congress has preferred civil-rights litigants by providing that courts must ordinarily award attorneys’ fеes if they prevail, but may tax attorneys’ fees against them only if their suit was unreasonable, frivolous, meritless, or vexatious. Congress has not, however, carved out an exception to Rule 54(d) relieving a losing civil-rights litigant of the burden of bearing the costs of litigation. The rationale for this distinction is clear. Whereas the magnitude and unpredictability of attorney’s fees would deter parties with meritorious claims
from
litigation, the costs of suit in the traditional sense are predictable and, compared to the costs of attorneys’ fees, small. See Baez
v. United States Department of Justice,
Ms. Poe also attacks the amount of costs awarded. This issue is within the sound discretion of the district court and *1109 ordinarily is not appealable. 9 A court of appeals lacks jurisdiction to hear an appeal where the sole issue is that the district court abused its discretion as to the amount of costs awarded. Here, however, the appellant has raised an issue of the court’s power over costs under the Christiansburg standard. Although that doctrine does not apply, we can and do review the merits of the cost judgment. No. abuse of discretion is apparent.
Accordingly we affirm.
Notes
. The Hon. Scott O. Wright, United States District Judge for the Western District of Missouri.
. Ms. Poe failed to comply with Title VIPs requirement that she file suit within ninety days of receiving her notice of a right to sue. 42 U.S.C. Sec. 2000e-5(f)(l). Thе dismissal of her Title VII claim is not in issue on this appeal.
. This term, in Missouri law, seems to include any act intentionally inflicting harm, but not within any traditional tort category.
. Restatement (Second) of Judgments Sec. 25 (1982) provides that res judicata applies “even though the plaintiff is prepared in the seсond action (1) To present evidence or grounds or theories of the case not presented in the first action .... ”
. Restatement (Second) of Judgments § 24, comment c (1982), correctly notes the following:
Transaction may be single despite different harms, substantive theories, measures or kinds of relief. A single transaction ordinarily gives rise to but one claim by one person against another. When a person by one act takes a number of chattels belonging to another, the transaction is single, and judgment for the value of some of the goods exhausts the claim and preсludes the injured party from maintaining one action for the remainder. In the more complicated case where one act causes a number of harms to, or invades a number of different interests of the same person, there is still but one transaction; a judgment based on the aсt usually prevents the person from maintaining another action for any of the harms not sued for in the first action.
That a number of different legal theories casting liability on an action may apply to a given episode does not create multiple transactions and hence multiрle claims. This remains true although the several legal theories depend on different shadings of the facts, or would emphasize different elements of the facts, or would call for different measures of liability or different kinds of relief.
The existence of several harms and theories doеs not necessarily create more than one claim.
. The Supreme Court equates “claim” and “transaction” (as it is defined by the Restatement) in a variety of contexts in which the idea of a claim is legally significant. See
United Mine Workers v. Gibbs,
. This Court reversed the District Court’s finding in Rimmer that the statute was facially unconstitutional after Poe I was tried.
. Even if
Porter
had been decided after
Poe I,
counsel was still free to pioneer the development of а prima facie tort theory. See
Federated Department Stores, Inc.
v.
Moitie,
. This Court has in the past ruled on cases where the sole claim on appeal was that the district court had abused its discretion in awarding costs.
