Manipulation of competition

Two kinds of manipulation, and why one code covers both

Match-fixing extracts value from outside the competition: a wager, a bribe, a third party's stake. It requires a payer. The subject of this page extracts value from inside the competition — a better draw, a higher draft pick, a fresher squad for a final — and requires only a format that rewards losing. There is no bribe, usually no bet, and frequently no technical rule broken at all.

The Olympic Movement Code on the Prevention of the Manipulation of Competitions reaches both, and it does so through four words in its definitions. Article 1.1 defines "benefit" to include money, gains, gifts and winnings, and then adds: "Sporting advantage is also a benefit." Without that sentence the Code would be a betting instrument. With it, losing a group match to secure an easier quarter-final is a Code violation on its face.^[1]

The offence itself, at Article 2.2(a), is "An intentional arrangement, act or omission aimed at an improper alteration of the result or the course of a competition in order to remove all or part of the unpredictable nature of the sports competition with a view to obtaining an undue benefit for oneself and/or for others". Two phrases carry weight: the course of a competition as well as its result, and omission as well as act — a deliberate non-performance qualifies. Article 2.6 then lists eight things that are not relevant to whether a violation occurred, of which two matter here: whether the participant's effort or performance was, or could be expected to be, affected; and "Whether or not the manipulation included a violation of a technical rule of the respective Sports Organisation." That last is the answer to "but they broke no rule". The standard of proof is the balance of probabilities, and sanctions run "from a minimum of a warning to a maximum of life ban", with mutual recognition by all other sports organisations.^[1]

The Athletics Integrity Unit names the non-betting variant outright and separates it from betting-driven fixing in its own glossary: "Deliberately losing, know[n] as Tanking, is to gain an undue sporting advantage in a competition. For instance, when athletes lose an event on purpose to compete against easier opponents in the latter phases of a competition." That is the cleanest official statement anywhere that the two are distinct offences inside one programme.^[2]

The federation codes are far less tidy. FIFA has no best-efforts obligation. Article 20(1) of its Disciplinary Code sanctions anyone who "directly or indirectly, by an act or an omission, unlawfully influences or manipulates the course, result or any other aspect of a match", with a minimum five-year ban and a fine of at least CHF 100,000 — and the word "unlawfully" is doing all the work, because playing badly on purpose is not obviously unlawful. UEFA's formulation is broader: acting "in a manner that is likely to exert an unlawful or undue influence on the course and/or result of a match… with a view to gaining an advantage", with liability extending to the club or association. UEFA also explains why outcomes of this kind are never reversed — a complaint filed after the competition stage has finished "can have no impact on the sporting result… and, therefore, the match cannot be replayed, unless the competent disciplinary body decides otherwise."^[3] [4]

The operative rule: “best efforts”, and how few sports have one

The generalisation worth making at the outset is that most sports have no best-efforts rule at all, and reach non-trying only through a residual clause about conduct that brings the sport into disrepute. UEFA's disciplinary regulations carry exactly such a hook; so do most codes.^[4]

Badminton is the outlier that actually wrote the rule down. Its Players' Code of Conduct requires players to be "Always us[e] one's 'best efforts' to win a match", alongside a duty to complete a match in progress unless reasonably unable to do so, and a general obligation not to engage in conduct contrary to the integrity of the game. The federation's own integrity material lists "not using best efforts" as a distinct corruption offence.^[5] [6] The sports that write it down are, unsurprisingly, the ones whose draws and seedings are decided by results.

There is a structural reason so few bother. A best-efforts rule is easy to draft and close to unenforceable against a competent professional, because effort is unobservable and tactical variation is legitimate. It bites only where the non-effort is ostentatious — serves driven into the net, no rally lasting more than four shots. That is the London 2012 fact pattern, and it is close to the only fact pattern that has ever produced a finding.

Football supplies the sharpest illustration of the gap. FIFA's one express anti-format-gaming provision is not about effort at all: Article 14(1)(d) sanctions "deliberately receiving a yellow or red card, including in order to be suspended for an upcoming match". Deliberately collecting a booking to clear a suspension before a knockout round is expressly sanctionable; deliberately playing badly is not.^[3]

London 2012: the anchor case

On the evening of Tuesday 31 July 2012, two Olympic women's doubles group matches at Wembley Arena were played to lose. The next morning the Badminton World Federation charged eight players — Wang Xiaoli and Yu Yang of China, Greysia Polii and Meiliana Jauhari of Indonesia, and both South Korean pairs, Jung Kyung Eun with Kim Ha Na and Ha Jung Eun with Kim Min Jung — under sections 4.5 and 4.16 of its Players' Code of Conduct with "not using one's best efforts to win a match" and "conducting oneself in a manner that is clearly abusive or detrimental to the sport". All four pairs appeared before the Disciplinary Committee at a Wembley hotel that morning. All four were disqualified.^[7] [8]

The appeals are consistently misreported. China did not appeal. Indonesia appealed and then withdrew before the appeal was considered. Both Korean pairs appealed and were rejected by the Chair of the Appeals Committee under clause 3.1 of the disciplinary regulations, which permits rejection where "the case is considered to be concluded with any fine or sanction already imposed" — a procedural gate, not a ruling on the merits. There was no appeal to the Court of Arbitration for Sport. Charge, hearing, disqualification, appeal and rejection were disposed of within about fourteen hours of a single day.^[9]

The sanction had live sporting consequences rather than symbolic ones: pairs from Australia, Canada, Russia and South Africa advanced to the quarter-finals, and by the time the federation published its account the Russians and Canadians had reached the semi-finals.^[9]

Two further details are more instructive than the disqualifications. First, the harsher punishments came from national federations, not the world body: South Korea imposed lifetime bans on its two pairs and two coaches, reported as reduced on appeal to six months for the players and two years for the coaches — a reduction attested only in agency reporting, with no Korean federation document confirming it — and Indonesia lifted its suspensions in November 2012. Second, and better: at its Council meeting of 30 November 2012 the federation decided it would not sanction any coach or entourage member because doing so was "not legally feasible", and amended the Code so that it could in future. The athletes were disqualified within hours; the people who may have instructed them were beyond the reach of the code.^[10]

What the federation changed is the part that generalises. It did not abolish the group stage, which had been introduced for London 2012 to give players more matches. It changed what happens after it: from Rio 2016, group winners take fixed positions in the bracket and all second-placed pairs go into a further draw to determine their opponents. Its secretary general put the reasoning plainly — the change would "eliminate any player's thoughts about actively trying to lose a match or matches, irrespective of other match results." The design principle is worth stating in the abstract, because it recurs: if the reward for finishing second is randomised at the moment the group ends, no team can know which opponent losing would buy. Losing becomes uninformative rather than forbidden.^[10]

One further badminton finding exists, and it is the only other clean one. In March 2022 an independent hearing panel found four Chinese men's doubles players had failed to use best efforts to win a match at the Fuzhou China Open in 2018; each received a suspended three-month ban with a two-year probationary period, and prize money was forfeited. A drafting curiosity worth a line: the charge sat inside the federation's betting code even though the offence charged was the non-betting one. Codes do not sort themselves as neatly as the distinction at the top of this page suggests.^[11]

Format-created incentives, and the design fixes

Gijón, 25 June 1982. West Germany beat Austria 1–0 in the final Group 2 match at El Molinón. Algeria had played its own final match the previous day, so both European sides knew before kick-off that a one- or two-goal German win would put both through and eliminate Algeria on goal difference. Hrubesch scored on ten minutes and the remaining eighty were largely uncontested. The best evidence is arithmetical rather than rhetorical: two shots in the entire second half — the fewest of any second half in the 796 World Cup matches in Opta's database — with the last shot in the 54th minute, 0.9 per cent of second-half touches in the opposition box, and 58 per cent of second-half passes played inside their own half against a World Cup average of 41.^[12]

What happened next must be stated carefully, because it is routinely overstated. Algeria protested formally to FIFA seeking the suspension of both associations. The protest was rejected and no disciplinary finding was made. No FIFA document confirming a hearing has been located, so the common formulation that FIFA held a hearing and cleared the two teams should not be written.^[13] The fix came instead through the format: from the 1986 World Cup the final round of matches in each group kicks off simultaneously. The mechanism is informational — neither side can know what result it needs. (No FIFA regulation text or contemporaneous announcement of that change was located; the sourcing is secondary but uniform, and the 1986 schedule itself is the citation of record.)^[14]

Barbados v Grenada, 27 January 1994. The score was 3–2 after extra time, 2–2 at ninety minutes — not 2–1, as almost every retelling has it. The Caribbean Cup qualifiers used a golden-goal variant in which the first extra-time goal ended the match and counted double. Barbados needed a two-goal margin to qualify. Leading 2–0 they conceded on 83 minutes, at which point a one-goal win no longer sufficed, and with about three minutes left they deliberately scored an own goal to force extra time, where a golden goal would deliver the margin. Grenada then tried to score at either end — a goal at either goal would deny Barbados the two-goal margin — and Barbados defended both. No disciplinary finding was made against either association or any player. The value of the case is not the farce but the fact that both sides played optimally against the incentives they were given: the rule produced the outcome, not the teams. No organiser documentation of the double-counting rule has been located; it is known only from contemporaneous and later journalistic accounts.^[15]

The 1998 Tiger Cup supplies the only located case in which a governing body fined both associations over a mutual attempt to lose. Indonesia and Thailand each sought to avoid meeting the hosts in the semi-final, and in injury time an Indonesian defender deliberately scored an own goal past two Thai defenders trying to prevent it. FIFA is reported to have fined both associations US$40,000 for violating the spirit of the game, with the defender banned for a year domestically and for life internationally. Both teams then lost their semi-finals. No FIFA primary decision has been located; the figures are uniformly reported and secondary.^[16]

The 2026 World Cup produced the modern version of the problem and, so far, nothing else. Paraguay's goalless draw with Australia on 25 June 2026 sent Australia through as runners-up and drew heavy criticism, on a combined expected-goals figure of 0.82. No disciplinary proceedings have been announced and no finding has been made; FIFA's post-tournament sanctions announcement of 21 August 2026 concerns incidents at the final and nothing else. Two errors circulating about it are worth correcting: the "investigation ordered" reported afterwards was South Korea's president ordering an inquiry into South Korea's own campaign, not a FIFA inquiry into the match; and on the third-placed-team mathematics a 1–0 loss would in fact have eliminated Australia, so the incentive was not the one critics assumed. The live structural criticism — and it is criticism, not finding — is that a 48-team format with twelve groups and eight best third-placed teams advancing makes a side's fate depend on results in other groups played later, which simultaneity inside a group cannot cure.^[17] [18]

Tanking in league sport

State the frame before the detail: in the North American leagues, losing on purpose is essentially never a rule violation. The draft rewards it by design — the worst team picks first — and the leagues have responded almost entirely by changing the reward rather than prohibiting the behaviour. Where clubs have been punished, the charge has been conduct detrimental to the league over statements or resting decisions, never a finding that games were thrown.

The NBA's lottery is an arms race in its own right. A coin flip between the worst team in each conference decided the first pick from 1966 to 1984; an unweighted lottery among non-playoff teams was adopted in June 1984 for the 1985 draft; it was reduced to the first three picks in 1986; weighted from 1990, with the worst record on 16.67 per cent; re-weighted in 1993 to give the worst team 25 per cent, effective 1994; and expanded to 13 and then 14 teams. The flattening came from a vote on 28 September 2017 and was first applied at the 2019 lottery: the three worst records each hold 14 per cent, four picks are drawn rather than three, and the worst team can fall no lower than fifth.^[19]

And the league changed it again on 28 May 2026. The Board of Governors approved a "3-2-1 Lottery", framed expressly as an anti-tanking measure and effective with the 2027 draft. The lottery expands from 14 teams to 16, each holding three, two or one ball; non-playoff teams get three except the three worst records, which are "draft relegated" and lose one; the two lowest play-in seeds get two balls and the losers of the 7v8 play-in get one. Balls are drawn to set the first sixteen picks, with relegated teams unable to fall below twelfth and others able to fall to sixteenth. No team's own pick may be first in two consecutive drafts, or top-five in three consecutive drafts, and the restriction attaches to the team's own pick even after it is traded. Most significantly, the league took express authority to reduce lottery odds, modify draft positions and impose significant fines for tanking — the first time a major North American league has written a tanking penalty into its draft rules.^[20]

The actual sanctions, and what each was for, are constantly muddled. Mark Cuban was fined US$600,000 on 21 February 2018 — personally, as owner, and not the club — "for public statements detrimental to the NBA" made on a podcast. The Dallas Mavericks as a club were fined US$750,000 on 14 April 2023 for conduct detrimental to the league in an elimination game, having rested key players. The Utah Jazz were fined US$500,000 on 12 February 2026 for pulling two players before the fourth quarter of two games "even though these players were otherwise able to continue to play and the outcomes of the games were thereafter in doubt", the commissioner adding that "Overt behavior like this that prioritizes draft position over winning undermines the foundation of NBA competition." Three months later came the lottery overhaul.^{[21] [22] [23]}

The Philadelphia "Process" era of 2013 to 2016 carries a negative finding worth stating: the league never fined or sanctioned the club over it. Its response was structural — the lottery flattening — plus the club's own decision to install a chairman of basketball operations above its general manager.^[24]

The other leagues vary widely. The NFL has no lottery and no anti-tanking mechanism at all: selection order is the reverse of the previous season's finish, non-playoff teams taking slots one to twenty by record with ties broken first on strength of schedule.^[25] Major League Baseball introduced a draft lottery in its 2022 agreement, first held that December: all eighteen non-postseason clubs enter, the lottery sets the top six picks, and the worst record is not guaranteed one; the stated purpose is "To remove an incentive for a club to finish with the worst overall record." Its distinctive repeat-tanking bar has actually bitten — large-market clubs cannot receive a lottery selection in consecutive years and small-market clubs cannot in three consecutive years, with ineligible clubs picking no earlier than tenth. For the 2025 lottery only sixteen of eighteen non-playoff clubs were eligible, the club with the worst record among those excluded. A separate prospect-promotion incentive awards extra picks to clubs whose top prospects win major awards after starting the season on the opening-day roster — a reward for not manipulating service time.^[26] [27] The NHL, in changes adopted for 2021 and 2022 and with no later amendment located, cut its lottery from three draws to two, so the worst-finishing club can fall no further than third — the frequently repeated formulation that it can fall no more than two spots confuses draws with places — and from 2022 capped how far a club can climb and barred any club from advancing by winning a draw more than twice in five years.^[28] The AFL uses a reverse-ladder order heavily modified by free-agency compensation and academy bid-matching, and abolished automatic results-based priority picks in 2012, replacing them with picks at the Commission's discretion.^[29]

One league has sanctioned a club over tanking, and how it charged the case is the point. On 19 February 2013, after interviewing 58 people, the AFL fined Melbourne A$500,000, banned its football operations manager from all club functions for eleven months and suspended its former senior coach for sixteen rounds. It expressly found that the club had not deliberately set out to lose matches — no board or executive directive, and neither coaches nor players setting out to lose — and instead found the two individuals had acted "in a manner which was prejudicial to the interests of the AFL". No draft picks were stripped. Set that beside the Cuban and Jazz fines and the pattern is unmistakable: leagues punish the conduct around tanking while declining to find that anyone tanked.^[30]

Resting players: from unwritten norm to written rule

The NBA's Player Participation Policy, approved on 13 September 2023 and effective that season, is the most developed written rule of its kind in world sport. It defines a star player as any player named to an All-NBA or All-Star team in any of the prior three seasons, and then imposes five rules: no more than one star unavailable for the same game; stars must be available for national-television and in-season tournament games; one-game star absences must be balanced between road and home, "with a preference… for such absences to occur in home games"; no long-term shutdown or near-shutdown, including a star beginning to play a materially reduced role in circumstances affecting the integrity of the game; and a rested healthy player must be present at the game and visible to fans.^[31]

Investigations trigger automatically on multiple star absences, on a star missing a national-television game, and on any statement by a general manager, coach, team personnel, investor, player or player representative that contradicts the injury report. Review is conducted by the league office with an independent physician. Long-term injury management is pre-approvable on two grounds — age 35 or over on opening night, or a career workload above 34,000 minutes or 1,000 games; or a serious injury history — on written medical submission at least a week before the first game to be missed. Penalties escalate: US$100,000 for a first violation, $250,000 for a second, and thereafter "$1 million more than its previous penalty", so a third offence costs $1.25m.^[31]

Six fines have been imposed under the policy: the Brooklyn Nets ($100,000, January 2024), the Atlanta Hawks ($100,000, November 2024, over a tournament game), the Utah Jazz ($100,000, March 2025), the Cleveland Cavaliers ($100,000 in November 2025 and then $250,000 in December 2025 as a second violation, the largest to date), and the Indiana Pacers ($100,000, February 2026, where the independent physician found the players could have played, including on reduced minutes). No team has reached the $1.25m tier.^[23] [31]

Three categories must be kept apart or the picture is wrong: participation-policy fines for player-availability breaches; conduct-detrimental fines under the league constitution, which is where the Mavericks' $750,000 and the Jazz's $500,000 sit; and injury-reporting fines for inaccurate disclosure, a separate offence again — the Philadelphia 76ers were fined US$100,000 on 3 December 2025 for failing to disclose a player's availability accurately before a game.^{[23] [31] [37]}

The comparable clause in European football is a contractual one. Article 6.01(a) of the UEFA Champions League regulations requires clubs, on entering, "to play in the competition until their elimination and to field their strongest team throughout the competition" — wording that has carried unchanged for at least a decade. No instance was located of UEFA sanctioning a club under it for fielding a weakened side. A written obligation that is never enforced is itself the finding.^[32]

The grey area, and where the rules actually draw the line

The honest way to handle the margins is to state where rules draw the line rather than where it ought to be drawn.

Resting before a final is not prohibited anywhere in world sport as such. It becomes actionable only where a league has written a participation rule or a competition has a strongest-team clause. Outside those, it is coaching.

A weakened side in a dead rubber is covered on paper by the Champions League clause and, so far as can be established, has never produced a sanction. The gap between the rule as written and the rule as enforced is the observation worth making.

Choosing a favourable weight class or event is a legitimate entry decision in every combat sport reviewed, and nothing in the Olympic Code or the codes surveyed reaches it, because there is no alteration of the result or the course of a competition.

Losing a heat to save energy is ordinary tactics where the heat decides only lane assignment. The athletics definition bites on a seeding benefit — losing on purpose to meet easier opponents later — not on a fatigue benefit.^[2]

And there is one case where the rules explicitly forgave it. After the men's team sprint at London 2012 on 2 August, the British rider Philip Hindes appeared to say he had deliberately crashed in a qualifying heat to force a restart; he later said the remark had been lost in translation. The IOC said the incident was not being investigated, on the basis that a restart after a crash was permitted by the rules as written, and no disciplinary finding was made. It is a clean illustration that "the rules permitted it" remains a real defence — and that the Olympic Code's provision disapplying the technical-rule requirement has never been used to override one.^[33]

Enforcement reality: proving that someone did not try

Sanctions for not trying, in pursuit of a sporting rather than a financial advantage, are extraordinarily rare. The verifiable global list is essentially three matters: the eight badminton players disqualified on 1 August 2012; the four Chinese doubles players sanctioned in March 2022 over a 2018 match; and the two associations fined over the 1998 Tiger Cup, on secondary sourcing only. The AFL's Melbourne case and the NBA fines belong to an adjacent category — sanctions for conduct around tanking, with no finding of tanking.^{[9] [11] [16] [30]}

The comparison that explains why happened in the same week of the same Games. On 31 July 2012 Japan drew 0–0 with South Africa in the Olympic women's football group stage in Cardiff, and the coach, Norio Sasaki, said at the post-match press conference that he had instructed his players not to win, so that Japan would finish second and stay in Cardiff for the quarter-final rather than travel to Glasgow. On 1 August 2012 — the same day that eight badminton players were disqualified for the same category of conduct — the chairman of the FIFA Disciplinary Committee, Marcel Mathier, reviewed those comments and decided that no disciplinary action would be taken. Two days later the IOC said it was content with that decision.^[34] [35]

Same Games, same week: an open admission in football produced nothing, and a visible performance in badminton produced eight disqualifications. The difference was not the conduct. It was that badminton had a best-efforts rule and football did not.

The evidentiary problem underneath is structural. The offence is a state of mind — an intention not to try — evidenced only by performance, and performance is legitimately variable; there is no equivalent of a positive sample or a betting alert. The doctrine is permissive rather than restrictive: the Olympic Code sets the standard at the balance of probabilities and says a technical-rule breach is not required. The bottleneck is proof, not law. In practice, findings have followed only where the non-performance was visible to the naked eye at the moment it happened, or where the actor said so afterwards — and even an admission produced nothing in the football and cycling cases above.^[1]

Which is why the bodies that have acted at scale have acted on the format and not on the conduct: simultaneous kick-offs from 1986, a post-group re-draw from Rio 2016, flattened lottery odds from 2019, a lottery rewritten again for 2027. The design fix is cheaper than the disciplinary one, and on the evidence it works better. No charge or sanction anywhere in world sport for not trying on a non-betting basis was located for 2024, 2025 or 2026 — the only live proceeding being a badminton matter opened in August 2026 in which no finding has been made.^{[14] [10] [19] [20] [36]} For the formats that create these incentives in the first place, see competition formats.
