delivered the opinion of the Court.
For the third time in 50 years the Court is asked specifically to rule that professional baseball’s reserve system is within the reach of.the federal antitrust laws.1 *260Collateral issues of state law and of federal labor policy are also advanced.
I
The Game
It is a century and a quarter since the New York Nine defeated the Knickerbockers 23 to 1 on Hoboken’s *261Elysian Fields June 19, 1346/with Alexander jay Cart-' wright as the instigator and the umpire. The teams were amateur, but the contest marked a significant date in baseball’s beginnings. That early game led ultimately to the development of professional baseball' and its tightly organized structure.
The Cincinnati Red Stockings came into existence in 1869 upon an outpouring of local pride. With only one Cincinnatian on- the payroll, this professional team traveled over 11,000 miles that summer, winning 56 games and tying one. Shortly thereafter, .on St. Patrick’s Day in 1871, the National Association of Professional Baseball Players was founded and the professional league was born.
The ensuing colorful days are well known. The ardent follower and the student of baseball'know of General Abner Doubleday; the formation of the National League in 1876; Chicago’s supremacy in the first year’s competition under the leadership of A1 Spalding and with Cap Anson at third base; the formation of the American Association and then of the Union Association in the 1880’s; the introduction of Sunday baseball; interleague warfare with cut-rate admission prices and player raiding; the developmént of the reserve “clau’se”; the emergence-in 1885 of the Brotherhood of Professional Ball Players, and in 1890 of the Players League; the appearance of the American League, or “junior circuit,” in 1901, rising from. the minor Western Association; the first World *262Series in 1903, disruption in 1904, and the Series’ resumption in ■ 1905; the short-lived Federal League on the majors’ scene during World War I years; the troublesome and discouraging episode' of the 1919 Series; the home run ball»; the shifting of franchises; the expansion of the leagues; the installation- in 1965 of the major league draft of potential new players; and the formation of the Major League Baseball Players Association in 1966.2
Then there are the many names, celebrated for one reason or another, that have sparked the diamond and its environs and that have provided tinder for recaptured thrills, for reminiscence and comparisons, and for conversation and anticipation in-season and off-season: Ty Cobb, Babe Ruth, Tris Speaker, Walter Johnson, Henry Chadwick, Eddie Collins, Lou Gehrig, Grover Cleveland Alexander, Rogers Hornsby, Harry Hooper, Goose Goslin, Jackie Robinson, Honus Wagner, Joe McCarthy, John McGraw, Deacon Phillippe, Rube Mar-quard, Christy Mathewson, Tommy Leach, Big Ed Delahanty, Davy Jones, Germany Schaefer, King Kelly, Big Dan Brouthers, Wahoo Sam Crawford, Wee Willie Keeler, Big Ed Walsh, Jimmy Austin, Fred Snodgrass, Satchel Paige, Hugh Jennings, Fred Merkle, Iron Man McGinnity, Three-Finger Brown, Harry and Stan' Coveleski, Connie Mack, Al Bridwell, Red- Ruffing, Amos Rusie, Cy Young, Smokey Joe Wood, Chief Meyers, Chief Bender, Bill Klem, Hans Lobert, Johnny Evers, Joe Tinker, Roy Campanella, Miller Huggins, Rube Bressler, Dazzy Vance, Edd Roush, Bill Wambsganss, Clark Griffith, Branch Rickey, Frank Chance, Cap Anson, *263Nap Lajoie, Sad Sam Jones, Bob O’Farrell, Lefty O’Doul, Bobby Veach, Willie Kamm, Heinié Groh, Lloyd and Paul Waner, Stuffy Mclnnis, Charles Comiskey, Roger Bresnahan, Bill Dickey, Zack Wheat, George Sisler, Charlie Gehringer, Eppa Rixey, Harry Heilmann, Fred Clarke, Dizzy Dean, Hank Greenberg, Pie Traynor, Rube Waddell, Bill Terry, Carl Hubbell, Old Hoss Radbourne, Moe Berg, Rabbit Maranville, Jimmie Foxx, Lefty Grove.3 The list seems endless.
And one recalls the appropriate reference to the “World Serious,” attributed to Ring Lárdner, Sr.; Ernest L. Thayer’s “Casey at the Bat”;4 the ring of “Tinker to *264Evers to Chance”;5 and all the other happenings, habits, , and superstitions about and around baseball that made. it the “national pastimé” or, depending upon the point of view, “the great American tragedy.” 6'
II
The Petitioner
The petitioner, Cürtis Charles Flood, born in 1938, began his major league career in 1956 when he signed a contract with the Cincinnati Reds for a salary of $4,000 for the season. He had no attorney or agent to advise him on that occasion. He was traded to the St. Louis Cardinals before the 1958 season. Flood rose to fame as a center fielder with the Cardinals during the- years 1958-1969. In those . 12 seasons he compiled- a batting average of .293. His best offensive season was 1967 when he achieved .335! He was .301 or better in six of the 12 St. Louis yéars. He participated in the 1964, 1967, and 1968 World Series. He played errorless ball in the field in. 1966, and once enjoyed 223 consecutive errorless games. Flood has received seven Golden Glove Awards. He was co-captain of his team from 1965-1969. He ranks among the 10 major league outfielders possessing the highest lifetime fielding averages:
*265Flood’s St. Louis compensation for the years shown was:
1961 $13,500 (including a bonus for signing)
1962 $16,000
1963 $17,500
1964 $23,000
1965 $35,000
1966 $45,000
1967 $50,000
1968 $72,500
10B9 $90,000
These figures do not include any so-called fringe benefits or World Series shares.
But at the age of 31, in October 1969, Flood was traded to the Philadelphia Phillies of the National League in a multi-player transaction. . He was not consulted about the trade. He was informed by telephone and received formal notice only after the deal had been consummated. In December he complained to the Commissioner of Baseball and asked that he be made a free agent and be placed at liberty to strike his own bargain with any other major league team. His request was denied.
Flood then instituted this antitrust suit7- in January 1970 in federal court for the Southern District of New York. The defendants (although not all were named in each cause of action) were the Commissioner of Baseball, the presidents of the two major leagues, and the 24 major league clubs. In general, the complaint charged violations of the federal antitrust laws and civil rights statutes, violation of state statutes and the common law, and the imposition of a form of peonage and involuntary *266servitude contrary to the Thirteenth Amendment and 42 U. S. C. § 1994, 18 U. S. C. § 1581, and 29 IT. S. C. §§ 102- and 103. . Petitioner sought declaratory and in-junctive relief and treble damages.
Flood declined to play for Philadelphia in 1970, despite a $100,000 salary offer, and he sat out the year. After the season was concluded, Philadelphia^ sold its rights to Flood to the Washington Senators.. Washington and the petitioner were able to conie tó terms for 1971- at a salary ■ of $110,000.8 Flood started the season but, apparently because he was dissatisfied with his performance,-he left the Washington club on April 27, early in the campaign. He has not played baseball since then.

The Present Litigation
Judge Cooper, in a detailed opinion, first denied a preliminary injunction, 309 F. Supp. 793 (SDNY 1970), observing on the way:'
“Baseball has been the national pastime for over one hundred years and/ enjoys a unique place in our American heritage. Major league professional baseball is avidly followed by millions of fans, looked upon with fervor and pride and provides a special source-.of inspiration and competitive team spirit especially for the young.
“Baseball’s status in the life of the nation is so pervasive that it would not strain credulity to say. the Court can take judicial notice that baseball is everybody’s business. To put it mildly and- with restraint, it would be unfortunate indeed if a fine sport, and profession, which brings surcease from daily travail and an escape from the ordinary to *267most inhabitants of this land, were to suffer in the least because of undue concentration by any one or any group on commercial and profit considerations. ' The game is on higher ground; it behooves every one to keep it there.” 309 F. Supp., at 797.
Flood's application for an early trial was granted. The court next deferred until trial its decision on the defendants’ motions to dismiss the primary causes of action, but granted a defense motion for summary judgment on an additional cause of action. 312 F. Supp. 404 (SDNY 1970).
Trial to the court took place in May and June 1970. An- extensive record was developed. In an ensuing opinion, 316 F. Supp. 271 (SDNY 1970), Judge Cooper first noted that:
“Plaintiff’s witnesses in the main concede that some form of reserve on players is a necessary element of the organization of baseball as a league sport, but contend that the present all-embracing system is needlessly restrictive and offer various, alternatives which in their view might loosen the bonds without sacrifice to the game. . . .
“Clearly the preponderance of credible proof does not favor elimination of the reserve clause. With the sole exception of plaintiff himself, it shows that even plaintiff’s witnesses do not contend that it is wholly undesirable; in fact they regard substantial portions meritorious. ...” 316 F. Supp., at 275-276.
He then held that Federal Baseball Club v. National League,, 259 U. S. 200 (1922), and Toolson v. New York Yankees, Inc., 346 U. S. 356 (1953), were controlling; that' it was not necessary to reach the issue whether exemption from .the antitrust laws would result because aspects of *268baseball now are a subject of collective bargaining; that the plaintiff’s state-law claims, those based on common law as well as on statute, were to be. denied because baseball was not “a matter which admits of diversity of treatment,” 316 F. Supp., at 280; that the involuntary servitude claim failed because of the absence' of “the essential element of this cause of action, a showing of compulsory service,” 316 F. Supp., at 281-282; and that judgment was to be entered for the defendants. Judge Cooper included'a statement of personal conviction to the effect that “negotiations could produce an accommodation on the reserve system which would be eminently fair and equitable to all concerned” and that “the reserve clause can be fashioned so as to find acceptance by player and club.” 316 F. Supp., at 282 and 284.
On appeal, the Second Circuit felt “compelled to affirm.” 443 F. 2d 264, 265 (1971). It regarded the issue of state law as one' of first impression, but concluded that the Commerce Clause precluded its application. Judge Moore added a concurring opinion in which he predicted, with respect, to the'suggested overruling of Federal Baseball and Toalson, that “there is no likelihood that such an event will occur.”9.- 443 F. 2d, at 268, 272.
*269We granted certiorari in order to look once , again at this troublesome and unusual, situation. 404 U. S. 880 (1971,);
IV
The Legal Background
A. Federal Baseball Club v. National League, 259 U. S. 200 (1922), was a suit for treble damages instituted by a member of the Federal League (Baltimore) against the National and American Leagues and others. The. plaintiff obtained a. verdict in the trial court, but the Court of Appeals reversed. The main brief filed by the plaintiff with this Court discloses that it was strenuously argued, among other things, that the business in which the defendants were engaged was interstate commerce; that the interstate relationship among the several clubs, located as they were in differént States, was predominant; that organized baseball represented an investment of colossal wealth; that it was an engagement in moneymaking; that gate receipts were divided by agreement between the home club and the visiting club; and that the business of baseball was to be distinguished from the mere playing of the game as a sport for physical exercise and diversion. See also 259 U. S., at 201-206.
• Mr. Justice Holmes, in speaking succinctly for a unanimous Court, said:
“The business is giving exhibitions of base ball, •which are purely staté affairs. . . . But the fact that in order to give the exhibitions the Leagues must induce free persons to cross state lines and *270must arrange and pay for their doing so is not enough to change the character of the business. . . . [T]he transport is a mere incident, not the essential thing. That to which it is incident, the exhibition, although made for money would not be called trade or commerce in the commonly accepted-use of those words. As it is put by the defendants, personal effort, not related to production, is not a subject of commerce. That which in its consummation is not commerce does not become commerce among the States because the transportation That we have- mentioned takes place. To repeat, the illustrations, given by the Court below, a firm of lawyers sending out a member to argue a case, or the Chautauqua lecture bureau sending out lecturers, does not engage in such commerce because the lawyer or leeturer goes to another State.
“If we are right the plaintiff’s business is to be described in the same way and the restrictions by contract that prevented the plaintiff from getting players to break their bargains and the other conduct charged against the defendants were not an interference with commerce among the States.” 259. Ur S., at 208-209.10
*271The Court thus chose not to be persuaded by opposing examples proffered , by the plaintiff, among them .(a) Judge Learned Hand’s decision on a demurrer to a Sherman Act complaint with respéct ’ to. vaudeville entertainers traveling a theater circuit covering several States, H. B. Marienelli, Ltd. v. United Booking Offices, 227 F. 165 (SDNY 1914); (b) the first Mr. Justice Harlan’s opinion in International Textbook Co. v. Pigg, 217 U. S. 91 (1910), to the effect that correspondence courses pursued through the mail constituted commerce among the States; and (c) Mr. Justice Holmes’ own opinion, for another unanimous Court,'on demurrer in a Sherman Act case, relating to cattle shipment, the interstate movement of which was interrupted for the finding of purchasers at the stockyards, Swift & Co. v. United States, 196 U. S. 375 (1905). The only earlier case the' parties wére able to loeate where the question was raised whether organized baseball was within the Sherman Act was American League Baseball Club v. Chase, 86 Misc. 441, 149 N. Y. S. 6 (1914). That court had answered the question in the negative.
B. Federal Baseball was cited a year later, and without, disfavor, in another opinion by Mr. Justice Holmes for a unanimous Court. The complaint charged antitrust violations with respect to vaudeville bookings. It was held, however, that the claim was not frivolous and that the bill should not have been dismissed. Hart v. B. F. Keith Vaudeville Exchange, 262 U. S. 271 (1923).11
It has also been cited, not unfavorably, with respect to the practice of law, United States v. South-Eastern *272Underwriters Assn., 322 U. S. 533, 573 (1944) (Stone, C. J., dissenting)with respect to out-of-state contractors, United States v. Employing Plasterers Assn., 347 U. S. 186, 196-197 (1954) (Minton, J., dissenting); and upon a general comparison reference, North American Co. v. SEC, 327 U. S. 686, 694 (1946).
In the years that followed, baseball continued to be subject to intermittent antitrust attack. The • courts, however, rejected these challenges on the -authority of Federal Baseball. In some cases stress was laid, although unsuccessfully, on new factors such as the development of radio and television with their substantial additional revenues to baseball.12 For the most part, however, the Holmes opinion was generally and necessarily accepted as controlling authority.13 And in the 1952 Report of the Subcommittee on Study, of Monopoly Power of the House Committee on the Judiciary, H. R. Rep. No. 2002, 82d Cong., 2d Sess., 229, it was said, in conclusion:
“On the other hand the overwhelming preponderance of the evidence established baseball’s need for some, sort of reserve clause. Baseball’s history shows that chaotic conditions prevailed when there _was no reserve clause. Experience points to no feasible substitute to protect the integrity of the game or to guarantee a comparatively even com*273petitive struggle. The evidence adduced at the hearings would clearly not justify the enactment of legislation flatly condemning the reserve clause.”
C. The Court granted certiorari, 345 U. S. 963 (1953), in the Toolson, Kowalski, and Corbett cases, cited in nn. 12 and 13, supra, and, by a short per curiam (Warren, C. J., and Black, Frankfurter, Douglas, Jackson, Clark, and Minton, JJ.), affirmed the judgments of the respective courts of appeals in those three cases. Toolson v. New. York Yankees, Inc., 346 U. S. 356 (1953). Federal Baseball was cited as holding “that the business of providing public baseball games for profit between clubs of professional baseball players was not within the scope of the federal antitrust laws,” 346 U. S., at 357, and:
“Congress has had the ruling under consideration but has not seen fit . to bring such business under these laws by legislation having prospective effect. The business has thus been left for thirty years to develop, on the understanding that it was. not subject to existing antitrust legislation. The present cases ask us to overrule the prior decision and, with retrospective effect, hold the legislation applicable. We think that if there are evils in this field which now warrant application to it of the antitrust laws it should be by legislation. Without re-examination of the underlying issues, the judgments below, are affirmed on the authority of Federal Baseball Club of Baltimore v. National League of Professional Baseball Clubs, supra, so far as that decision determines that Copgress had no intention of including the business of baseball within the scope of the federal -antitrust laws.” Ibid.
This quotation reveals four reasons for the Court’s affirmance of Toolson and its companion cases: (a) Congressional awareness for three decades of the. Court’s ruling in Federal Baseball, coupled with congressional *274inaction, (b) The fact that baseball was left alone to develop. for that period upon the understanding that the reserve system was not subject to existing federal antitrust laws, (e) A reluctance to overrule Federal Baseball with consequent retroactive effect, (d) A professed desire that any needed remedy be provided by legislation rather than by court decree. The emphasis in Toolson. was on the determination, attributed evén to Federal Baseball, that Congress had no intention to include baseball within the reach of the federal antitrust laws. Two Justices (Burton and Reed, JJ.) dissented, stressing the factual aspects, revenue sources, and the absence of an express exemption of organized baseball from the Sherman Act. 346 U. S., at 357. The 1952 congressional study was mentioned. Id., at 358, 359, 361.
It is of interest to note that in Toolson the petitioner had argued flatly that Federal Baseball “is wrong and must be overruled,” Brief for Petitioner, No. 18, O. T. 1953, p. 19, and that. Thomas Reed Powell, a constitutional scholar of no small stature, urged, as counsel for an amicus, that “baseball is a unique enterprise,” Brief for Boston American League Base Ball Co. as Amicus Curiae 2, and that “unbridled competition as applied to baseball would not be in the public interest.” Id., at 14.
D. United States v. Shubert, 348 U. S. 222 (1955), was a civil, antitrust action against defendants engaged in the production of legitimate theatrical attractions throughout the United States and in' operating theaters for the presentation of such attractions. The District Court had dismissed the complaint on the authority of Federal Baseball and Toolson. 120 F. Supp. 15 (SDNY 1953). This Court reversed. Mr. Chief Justice Warren noted the Court’s broad conception of “trade or commerce” in the antitrust statutes and the .types of enterprises already held to bé within the reach of that phrase. *275He stated that Federal Baseball and Toolson afforded no basis for a conclusion that businesses built around the performance of local exhibitions are exempt from the antitrust laws. 348 U. S., at 227. He then went on to elucidate the holding in Toolson by meticulously spelling out the factors mentioned above:
“In Federal Baseball, the Court, speaking through Mr. Justice Holmes, was dealing with the business of baseball 'and nothing else. . . . The travel, the Court concluded, was 'a mere incident, not the essential thing.5 ...
“In Toolson, where the issue was the same as in Federal Baseball, the Court was confronted with a unique combination of circumstances. For over 30 years there had stood a decision of this Court specifically fixing the status of the baseball business under the antitrust laws and more particularly the validity of the so-called ‘reserve clause.5 During this period, in reliance on the Federal Baseball precedent, the baseball business had grown and developed. . . ' And Congress, although it had actively considered the ruling, had not seen fit to reject it by amendatory legislation. Against this' background, the Court in Toolson was asked to overrule Federal Baseball on the ground that it was out of step with subsequent decisions reflecting present-day concepts of interstate commerce. The Court, in view of the circumstances of the case, declined to do so. But neither did the Court necessarily reaffirm all that was said in Federal Baseball.. Instead, ‘[w]ithout re-examination of the .underlying issues,5 the Court adhered to Federal Baseball. ‘so far as that decision determines that Congress had no intention of including the business of baseball within the seope of the federal antitrust laws.5 346 *276U. S., at 357. In short, Toolson was a narrow application of the rule of stare decisis.
. . If the Toolson holding is to be expanded— or contracted — the appropriate remedy lies with Congress.” 348 U. S., at 228-230.
E. United States v. International Boxing Club, 348 U. S. 236 (1955), was a companion to Shubert and was decided the same day. This was a civil antitrust action against defendants engaged in the business of promoting professional championship boxing contests. Here again the District Court had dismissed the complaint in reliance upon Federal Baseball and Toolson. The Chief Justice observed that “if it were not for Federal Baseball and Toolson, we think that it.would be too clear for dispute that the Government’s allegations bring the defendants within, the scope of the Act.” 348 U. S., at 240-241. He pointed out that the defendants relied on the two baseball cases but also would have been content with a more restrictive interpretation of them than the Shubert defendants, for the boxing defendants argued that the cases immunized only businesses that involve exhibitions of an athletic nature. The Court accepted neither argument. It again noted, 348 U. S., at 242, that “Toolson neither overruled Federal Baseball nor-necessarily reaffirmed all that was said in Federal Baseball." It stated:
“The controlling consideration in Federal Baseball and Hart was, instead, a very practical one— the degree of interstate activity involved in the particular business under- review. It follows that stare decisis cannot help the defendants here; for, contrary to their argument, Federal Baseball did not hold that all businesses based on professional sports were outside the scope of the antitrust laws. The- issue confronting us is, therefore, not whether a previously granted exemption should continue, *277but whether an exemption should be granted in the first instance. And that issue is for Congress to resolve, not this Court.” 348 U. S., at 243.
The Court noted the presence - then in Congress of various bills forbidding, the application of the antitrust laws to “organized professional sports enterprises”; the holding of extensive hearings on some of these; subcommittee opposition; a postponement recommendation as to baseball; and the fact that “Congress thus left intact the then-existing coverage of the antitrust laws.” 348 U. S., at 243-244.
Mr. Justice Frankfurter, joined by Mr. Justice Minton, dissented. “It would baffle the subtlest ingenuity,” he said,- “to find a single differentiating factor between other sporting, exhibitions . . . and baseball insofar as the conduct of the sport is relevant to the criteria or considerations by which the Sherman Law becomes applicable to a 'trade or commerce.’ ” 348 U. S., at 248. He went on:
“The Court decided- as it did in the Toolson case as an application of the doctrine of stare decisis. That doctrine is not, to be sure,, an imprisonment of reason. But neither is it a whimsy. It can -hardly be that this Court gave a preferred position to baseball because it is the great American sport. ... If stare decisis be one aspect of law, as it is, to disregard it in identic situations is mere caprice.
“Congress, on the.other hand, may yield to sentiment and be capricious, subject only to due process. ...
“Between them, this case and Shubert illustrate that nice but rational distinctions áre inevitable in adjudication. I agree with the Court’s opinion in' Shubert for precisely the’ reason that constrains me to dissent in this case.” 348 U. S., at 249-250.
*278Mr. Justice Minton also separately dissented on the ground that boxing is not trade or commerce. He added the comment that “Congress has not attempted” to control baseball and boxing. 348 U. S., at 251, 253. The two dissenting Justices, thus, did not call for the overruling of Federal Baseball and Toolson; they merely felt that boxing should be under the same umbrella of freedom as was baseball and, as Mr. Justice Frankfurter said, 348 U. S., at 250, they could not'exempt baseball “to the exclusion of every other sport different not one legal jot or tittle from it.” 14
F. The parade marched on. Radovich v. National Football League, 352 U. S. 445 (1957), was a civil Clayton Act case testing the application of the antitrust laws to professional football. The District Court dismissed. The Ninth Circuit affirmed in part on the basis of Federal Baseball and Toolson. The court did not hesitate to “confess that the strength of the pull” of the baseball cases and of International Boxing. “is about equal,” but then observed that “[fjootball is a team sport” and boxing an individual one. 231 F. 2d 620, 622.
This Court reversed with an opinion by Mr. Justice Clark. He said that the Court made its ruling in Tool-son “because it was concluded that more harm would be done in overruling -Federal Baseball than in upholding a ruling which at best was of dubious validity.” 352 U. S., at 450. He noted that Congress had not acted. He then said:
“All this, combined with the flood of litigation that woüld follow its repudiation, the harassment that would .ensue, and the retroactive effect of such a decision, led the Court to the practical result that *279it should sustain the unequivocal line of authority-reaching over many years.
■ “[S]ince Toolson and Federal Baseball are still cited as controlling authority in antitrust actions involving other fields of business, we now specifically limit the rule there established to the facts there involved, i. e., the business of organized professional baseball. As long as the Congress continues to acquiesce wfe should adhere to — but not extend— thé interpretation of the Act made in those cases....
“If this ruling is unrealistic, inconsistent, or illogical) it is sufficient to answer, aside from the distinctions between the businesses, that were we considering the question of baseball for the first time* upon a clean slate we would have no doubts. But Federal Baseball held the business of baseball outside the scope of the Act. No other business claiming the coverage of those cases has such an adjudication. We, therefore, conclude that the orderly way to eliminate error or discrimination, if any there be, is by legislation and not by court decision. Congressional processes are more accom-modative, affording the whole industry hearings and an opportunity to assist in the formulation of new legislation. The resulting product is therefore more likely to protect the industry and the public alike. The. whole scope of congressional action would be known long in advance and effective dates for the legislation could be. set in the future without the injustices of retroactivity and surprise which might follow court action.” 352 U. S., at 450-452 (footnote omitted).
Mr. Justice Frankfurter dissented essentially for the reasons stated in his dissent in International Boxing, *280352 U. S., at 455. Mr. Justice Harlan, joined by Mr. Justice Brennan, also dissented because he, too, was “unable to distinguish football from baseball.” 352 U. S., at 456. Here again the dissenting Justices did not . call for.the overruling of the baseball decisions. They merely could not distinguish the two spqrts and, out of respect for stare decisis, voted to affirm.
G. Finally, in Haywood v. National Basketball Assn., 401 U. S. 1204 (1971), Mr. Justice Douglas, in his capacity as Circuit Justiqe, reinstated a District Court’s injunction.pendeníe lite in favor of a professional basketball player and said, “Basketball ... . does, not enjoy exemption from-the antitrust laws.” 401 U. S., at 1205.15 ’
H. This series of decisions understandably spawned extensive commentary,16 some of it mildly critical and *281much of it not; nearly all of .it looked to Congress for any remedy that might be deemed essential.
I. Legislative proposals have been numerous arid persistent. Since Toolson more than 50 bills have been introduced in Congress relative to the applicability or nonapplicability of the antitrust laws to baseball.17 A few of these passed one house or the other. Those that did would have expanded, .not restricted, the reserve system’s exemption to other professional league sports. And the Act of Sept. 30, 1961, Pub.. L.- 87-331, 75 Stat. 732, and the merger addition thereto effected by the Act of Nov. 8, 1966, Pub. L.. 89-800, § 6 (b), *28280 Stat. 1515, 15 U. S. C. §§ 1291-1295, were also expansive rather than restrictive as to antitrust exemption.18
V
In view of all this, it seems appropriate now to say that:
1. Professional baseball is a business and it is engaged in interstate • commerce.
2. With its reserve system enjoying exemption from the federal antitrust laws, baseball is, in a very-distinct Sense, an exception and an anomaly. Federal Baseball and Toolson have become an aberration confined to baseball.
3. Even though others might regard this as “unrealistic,, inconsistent, or illogical,” see Radovich, 352 TJ. S., at 452, the aberration is an established one, and one that has been recognized not only in Federal Baseball and. Toolson, but in Shubert, International Boxing, and Radovich, as well, a total of five consecutive cases in this Court. It is an aberration that has been with us now for half a century, one heretofore deemed fully entitled to the benefit of stare decisis, and one that has survived the Court's expanding concept of interstate commerce. It rests on a recognition and an acceptance of baseball’s unique characteristics and needs.
4. Other professional sports operating interstate — foot*283ball, boxing, basketball, and, presumably, hockey19 and golf20 — are not so exempt.
5. The advent of radio and television, with their consequent increased coverage and additional revenues, , has not occasioned an overruling of Federal Baseball and Toolson.
6. The Court has emphasized that since 1922 baseball, with full and continuing congressional awareness, has been allowed to develop and to expand unhindered by federal legislative action. . Eemedial legislation has been introduced repeatedly in Congress but none has ever been enacted. The Court, accordingly ^ has. concluded that Congress as yet has had no intention to subject baseball’s reserve system to the reach of the antitrust statutes. This, obviously, has been deemed to be something other than mere congressional silence and passivity. Cf. Boys Markets, Inc. v. Retail Clerks Union, 398 U. S. 235, 241-242 (1970).
7. The Court has expressed concern about the confusion and the retroactivity problems that inevitably would result with a judicial overturning of Federal Baseball. It has voiced a preference that if any change is to be made, it come by legislative action that, by its nature, is only prospective in operation.
8. The Court noted in Radovich, 352 U. S., at 452, that the slate with respect to baseball is hot clean. Indeed, it has not been clean for half a century.
This emphasis and this concern are still with us. We. continue to be loath, 50 years after Federal Baseball and almost, two decades after Toolson, to overturn those cases judicially when Congress, by its positive inaction, *284has allowed those decisions to stand for so long and, far ,beyond mere inference and implication, has clearly evinced a desire not to disapprove them legislatively.
Accordingly, we adhere once again to Federal Baseball and Toolson and to their application to professional baseball. We adhere also to International Boxing and Rado-vich and to their respective applications to professional boxing and .professional football. If there is any inconsistency or. illogic in all this, it is an inconsistency and illogic of long standing that is to be remedied by the Congress and not by this Court. If we were to act otherwise, .we would be withdrawing from the conclusion as to congressional intent made in Toolson and from the concerns as to retrospectivity therein expressed. Under these circumstances, there is merit in consistency even though some might claim that beneath that consistency is a layer of inconsistency.
The petitioner’s argument as to the application of state antitrust laws deserves, a word. Judge Cooper rejected the state law claims because state antitrust regulation would conflict with federal policy and because national “uniformity1 [is required] in any regulation of baseball and its reserve system.” 316 F. Supp., at 280. The Court of Appeals,' in affirming,' stated, “[A]s the burden on interstate commerce outweighs the states’ interests in regulating baseball’s reserve system, the Commerce Clause precludes the application here of state antitrust law.” 443 F. 2d, at 268. As applied to organized baseball, and in the light of this Court’s observations and holdings in Federal Baseball, in Toolson, in Shubert, in International Boxing, and in Radovich, and despite baseball’s allegedly inconsistent position taken in the past with respect to the application of state law,21 *285these statements adequately dispose of the - state law claims.
The conclusion we have reached makes it unnecessary for us to consider the respondents5 additional argument that the reserve system is a mandatory subject of collective bargaining and that federal labor policy therefore exempts the reserve system from the operation of federal antitrust laws.22
We repeat for this case what was said in Toolson:
“Without re-examination of the underlying issues, the [judgment] below [is] affirmed on the authority of Federal Baseball Club of Baltimore V; National League of Professional Baseball Clubs, supra, so far as that decision determines that Congress had no intention of including the business of baseball within the scope of the federal antitrust laws.” 346 U. S., at 367.
And what the Court said in Federal Baseball in 1922 and what it said in Toolson in 1953, we say again, here in 1972: the remedy, if any is indicated, is for congressional, and not judicial, action.
The judgment of the Court of Appeals is
Affirmed.
Me. Justice White joins in the judgment of the Court, and in all but Part I of the Court’s opinion. Me. Justice Powell took no part in the consideration or decision of this case.The reserve system, publicly introduced into baseball contracts in 1887, see Metropolitan Exhibition Co. v. Ewing, 42 F. 198, 202-204 (CC SDNY 1890), centers in the uniformity of player contracts; the confinement of the player to the club that has him under the contract; the assignability .of the player’s contract; and the ability of the club annually to renew the contract unilaterally, subject to a stated salary minimum. Thus
A. Rule 3 of the Major League Rules provides in part:
“(a) UNIFORM CONTRACT. To preserve morale., and to produce the similarity of conditions necessary to keen competition, the contracts between all clubs and their players in the Major Leagues shall be in a single form which shall be prescribed by the Major League Executive Council. No club shall make a contract different from the uniform contract or a contract containing a non-reserve clause,' except with the written approval of the Commissioner. . . .
“(g) TAMPERING. To preserve discipline and competition, and to prevent the enticement of players, coaches, managers and umpires, there shall be no negQtiations or dealings respecting employment, either present or prospective, between any player, coach or manager ■and any club other than-the club with which he is under contract or acceptance of terms, or by which he is- reserved, or which has the player on its Negotiation List, or between any umpire and any league other than the league with which he is under contract or acceptance of terms, unless the club or league with which he is connected shall have, in writing, expressly authorized such negotiations or dealings prior to their commencement.”
B. Rule 9 of the Major League Rules provides in part:
“(a) NOTICE. A club may assign to another club an existing con-' tract with a player. The player, upon receipt of written notice of such assignment, is by his contract bound to serve the assignee.
“After the date of such assignment all rights and obligations of the *260assignor clubs thereunder shall become the rights and obligations of the assignee club . . . .”
C. Rules 3 and 9 of the Professional Baseball Rules contain provisions parallel to those just quoted.
D. The Uniform Player’s Contract provides in part:
“4. (a) ... The Player agrees that, in addition to other remedies, the Club shall be. entitled to .injunctive arid other equitable relief to prevent a breach of .this contract by the Player, including, among others, the right to enjoin the Player from playing baseball for any other person or organization during the term of this contract.”
“5. (a). The Player agrees that, while under contract, and prior to .expiration of the Club’s right to renew this contract,-' he will not play baseball otherwise than for the Club, except that the -Player may participate in post-season games under the conditions prescribed in the Major League Rules. . . .”
“6. (a) The Player agrees that this contract may be assigned by the Club (and reassigned by any assignee Club) to any other Club in accordance with the Major League Rules and the Professional Baseball Rules.”
“10. (a) On or before January 15 (or if a Suriday, then the next preceding business day) of the year next following the last playing season covered by this contract, the Club may tender to the Player a contract for the term of that year by mailing the same to the Player at his address following his signature hereto, or if none be given, then at his last address of record with the Club. If prior •to the March 1 next succeeding said January 15, the Player and the Club have not agreed upon the terms of such contract, then on or before 10 days after said March 1, the Club shall have the right by written notice to the Player at said address to renew this contract for the period of- one year on the same terms, except that the amount payable to the Player shall be such as the club shall fix in said notice; .provided, however, that said amount, if fixed by *261a Major League Club, shall be an amount payable at a rate not less than 80% of the rate stipulated for the preceding year.
“(b) The Club’s right to renew this contract, as provided in sub-paragraph (a) of this paragraph 10, and the promise of the Player not to play otherwise than with the Club have been taken into consideration in determining the amount payable under paragraph 2 hereof.”

These are names only from earlier years. By mentioning some, one risks unintended omission of others equally celebrated.
Millions have known and enjoyed baseball. One writer knowledgeable in the field of sports almost assumed that everyone did until, one day, he discovered otherwise:
“I knew a cové who!d never heard of Washington and Lee, Of Caesar and Napoleon from the ancient jamboree,
But, bli’me, there are queerer things than anything like that, For here’s a cove who never, heard of ‘Gasey at the Bat’!
“Ten million never heard of Keats, or Shelley, Burns or Poe;
But they know ‘the air was shattered by the force of Casey’s blow’;
They never heard of Shakespeare, nor of Dickensj-iike as not, But they know the somber drama from old Mudville’s haunted lot.
“He never heard of Casey! Am l\ireaming? Is it true?
Is fame- but windblown ashes when the summer day is through?
Does greatness fade so quickly and is grandeur doomed to die That bloomed in early morning, eré the dusk rides down the sky?”
“He Never Heard of Casey” Grantland Rice, The Sportlight, New York Herald Tribune, June 1, 1926, p. 23.
“These are the saddest of possible words,
'Tinker to Evers to Chance.’
Trio of bear cubs, and fleeter than birds,
'Tinker to Evers to Chance.’
Ruthlessly pricking our gonfalon bubble,'
Making a Giant hit into a double—
Words that are weighty with nothing but trouble:
‘Tinker to Evers to Chance.’ ”
Franklin Pierce Adams, Baseball’s Sad Lexicon.

“And properly so. Baseball’s welfare and future -should not be for politically insulated interpreters of technical antitrust statutes but rather should be for the voters through their elected representatives. If baseball-is to be damaged by statutory regulation, let the congressman face his constituents the next November and also face the consequences of his baseball voting record.” 443 F. 2d, at 272.
Cf. Judge Friendly’s comments in Salerno v. American League, 429 F. 2d 1003, 1005 (CA2 1970), cert. denied, sub nom. Salerno v. Kuhn, 400 U.S. 1001 (1971):
“We freely acknowledge our belief that Federal Baseball was not one of Mr. Justice Holmes’ happiest days, that the rationale of Toolson is extremely dubious and that, to use the Supreme Court’s *269own adjectives, the distinction between baseball and other professional sports is 'unrealistic,’ ‘inconsistent’, and ‘illogical.’. . . While we should not fall out of our chairs with surprise at the news that Federal Baseball and Toolson had been overruled,'we are not at all certain the Court is ready to give them a happy despatch.”
“What really saved baseball, legally at least; for the . next half century was the protective canopy spread over it by the United States Supreme Court’s decision in the Baltimore Federal League anti-trust suit against Organized Baseball in 1922. In it Justice Holmes, speaking for a unanimous court, ruled.that the business of giving baseball exhibitions for profit was not ‘trade or commerce in the commonly-accepted use of those words’ because ‘personal effort, not related to production, is not a subject of commerce’; nor was it interstate, because the movement of ball clubs across state lines was merely ‘incidental’ to the business. It should be noted that, contrary to what many believe, Holmes did call baseball a business; time and again those who have not troubled to read the text of the decision have claimed incorrectly that the court said baseball was a sport and'not a business.” 2 H. Seymour, Baseball 420 (1971).
On remand of the Hart case the trial court dismissed the complaint at the close of the evidence. The Second Circuit affirmed on the ground that the plaintiff’s evidence failed to establish that the interstate transportation was more than incidental. 12 F. 2d 341 (1926). This Court denied certiorari, 273 U. S. 703 (1926).

While I joined the Court’s opinion in Toolson v. New York Yankees, Inc., 346 U. S. 356, I have lived to regret it; and I would now correct what I believe to be its fundamental error.
The Court’s reliance upon congressional inaction disregards the wisdom of Helvering v. Hallock, 309 U. S. 106, 119-121, where we said:
“Nor does want of specific Congressional repudiations . . .'serve as an implied instruction by Congress to us not to reconsider, in the light of new experience . . . those decisions .... It would require very persuasive circumstances enveloping Congressional silence to *288debar this Court from re-examining its own doctrines. . . . Various considerations, of parliamentary tactics and-strategy might be suggested as reasons for the inaction of . . .. Congress, but they would only be sufficient to indicate that we walk on quicksand when we try to find in the absence of corrective, legislation a controlling legal principle.” "
