A reading of the Switkowski review, the AFL Anti-Doping Tribunal decision and the Court of Arbitration for Sport award. Written looking back at the record as it stood once the appeals were exhausted.
There are two versions of the Essendon saga. There is the one that lived in headlines, all drug dungeons and stomach injections and "the blackest day in Australian sport." And there is the one that lives in the documents, which is quieter, more precise and in some ways more troubling, because the documents do not deal in outrage. They deal in findings.
This piece is about the second version. It sets aside what was shouted and looks at what was actually concluded, by whom, on what standard of proof, and on what evidence. It is not a defence of anyone and it is not a prosecution of anyone. It is an attempt to read the record honestly, including the parts that cut against whatever you walked in believing.
Part One: How the Court of Arbitration for Sport actually reasoned
The single most misunderstood fact of the entire saga is this: no Essendon player ever returned a positive drug test. There was no failed sample, no analytical "gotcha." That is true, and the people who repeat it are not wrong.
What they usually miss is that under the World Anti-Doping Code, you do not need a positive test to establish a violation. A test is one way to prove a substance was used. It is not the only way. The Code expressly allows a violation to be established by "any reliable means," including admissions, witness evidence, documents, and inference from a body of circumstantial material. So the absence of a positive test did not end the matter. It simply meant the case had to be built a different way.
That is exactly what happened, and it is why the AFL Tribunal and the Court of Arbitration for Sport, looking at substantially the same evidence, reached opposite conclusions.
The standard of proof. Anti-doping cases are not criminal trials. The standard is not "beyond reasonable doubt." Nor is it the ordinary civil standard of "more likely than not." It sits between the two, and it has a name: comfortable satisfaction. The tribunal must be comfortably satisfied that the violation occurred, bearing in mind the seriousness of the allegation. The more serious the allegation, the more cogent the evidence needs to be, but the bar never rises all the way to criminal certainty. This is the standard CAS applied, and it is the standard that matters for understanding everything that follows.
Links in a chain versus strands in a cable. Here is the heart of it, and it is worth slowing down for, because this is the actual hinge on which the case turned.
When the matter was before the AFL Anti-Doping Tribunal, the evidence was assessed in a way that has been described as "links in a chain." Picture a chain: it is only as strong as its weakest link. If any single link fails, the whole chain breaks. Assess the evidence that way, and the case has a vulnerability, because several individual pieces of it, taken alone, could not carry the full weight. The Tribunal was not comfortably satisfied. In March 2015 it cleared the players.
On appeal, the case was reframed using a different metaphor, one drawn from the old law of evidence: "strands in a cable." A cable is not a chain. It is made of many individual strands, no one of which could hold the load by itself, twisted together into something that can. The point is that circumstantial evidence does not work like a chain at all. Weak individual strands, woven together, can produce a rope strong enough to bear a conclusion, even though no single strand would have held.
CAS adopted the cable approach. It looked at the whole body of material together rather than testing each piece in isolation to see whether that piece alone proved the case. Assessed that way, the panel was comfortably satisfied. This is not a legal trick or a loophole. It is a genuinely orthodox way to handle circumstantial evidence, and reasonable lawyers can and did argue about which framing was correct. But it explains how two expert bodies looked at the same facts and disagreed. They were not weighing different evidence. They were weighing it differently.
What the panel actually concluded was administered. The substance at the centre of the case was Thymosin Beta-4, a peptide that promotes tissue repair and recovery. No vial was produced in evidence with a player's name on it. Instead, the panel reasoned toward TB-4 from a cluster of facts: the consent forms players signed named "Thymosin"; the sports scientist's stated purpose was soft-tissue recovery; of the various forms of thymosin, the one that fits that purpose is Beta-4, not the immune-boosting forms; the sourcing and supply evidence pointed to TB-4; and so on. Crucially, the panel did not claim to trace the exact vial from supplier to syringe. It concluded, on the whole body of evidence, that the substance used was TB-4, while expressly acknowledging it could not pin down every step of the supply chain.
Why the players could not get their bans reduced. This is the part most people skip, and it is essential. Even once a violation is established, the Code allows for reduced sanctions where an athlete can show "no significant fault or negligence." The players ran this argument. It failed. The panel found they were "significantly at fault," and the reasons are specific: they signed consent forms for injections of substances they could not name; they made little or no inquiry into what they were being given; the program was kept from the club doctor; and across the testing missions conducted that season, the injections were not declared on doping control forms, despite the players being asked each time whether they had taken supplements. The anti-doping authority's chief executive summarised it as, at best, not asking the questions they should have, and at worst, a culture of secrecy and concealment.
Two things are true at once here, and holding both is the whole discipline of reading this case honestly. The players were, in a real sense, let down by the people who were supposed to protect them. And they were also, in the eyes of the Code, responsible for what went into their own bodies. The Code is built that way deliberately. Strict responsibility is the price of the level playing field.
Part Two: The chain of reports, in sequence
The findings did not arrive all at once. They came in stages, and the stages matter, because each body was answering a different question.
The Switkowski review (May 2013). This was commissioned by Essendon itself, not imposed on it, and it was not a doping investigation. Ziggy Switkowski, a former Telstra chief executive, was asked to examine governance. He could not interview the sports scientist, who had already left, and he could not rule on what substances were used. Within those limits, his finding was still severe. He described what he found as a pharmacologically experimental environment that was never adequately controlled, challenged, or documented. He identified the marginalisation of the club's medical staff, the absence of proper records, diffuse lines of authority and a chief executive and board who were not informed. This was a governance verdict and it was damning on its own terms, entirely separate from any question of doping.
The AFL sanctions (August 2013). Before any doping finding existed, the AFL charged the club and several officials with conduct that brought the game into disrepute, centred on governance and duty of care rather than on doping. The club was fined two million dollars, excluded from the 2013 finals and stripped of draft selections. The senior coach was suspended for twelve months. These penalties were for the governance failure. They did not depend on proving that any banned substance had been used and at that point, none had been proven.
The AFL Anti-Doping Tribunal (March 2015). This was the first body to rule on doping itself. Applying comfortable satisfaction, assessing the evidence in the chain-like way described above, it was not satisfied that the players had been administered TB-4. It cleared all of them. For a moment, the doping case was over.
The CAS appeal (January 2016). The World Anti-Doping Agency appealed to the Court of Arbitration for Sport. A CAS appeal is a hearing de novo, meaning the case is heard afresh rather than as a review of the Tribunal for error and new evidence is permitted. WADA reframed the evidence as a cable rather than a chain and brought additional material. The panel, chaired by a senior London barrister and including a former Chief Justice of New South Wales, upheld the appeal. It found the violation established to its comfortable satisfaction, rejected the "no significant fault" plea and imposed two-year bans on all 34 players, backdated so that most expired in November 2016. It is worth noting the fault finding was reached by majority, not unanimously.
The Swiss Federal Tribunal (October 2016). A CAS award can be challenged only on narrow grounds and only to the Swiss Federal Tribunal, since CAS sits in Lausanne. The players' challenge was not entertained, partly on the procedural ground that they had accepted the CAS process at the time. The Tribunal also indicated the ban would have stood regardless. That was the end of the road. The finding was final.
The parallel finding (January 2016). Separately, WorkSafe Victoria pursued Essendon under occupational health and safety law for exposing employees to risk. The club was convicted and fined. This matters because it is a finding under an entirely different body of law, by a different authority, on a different test. It did not rely on the doping conclusion at all. It rested on the duty an employer owes the people who work for it.
Part Three: What was proven, what was inferred, and what remains unknown
The honest reader needs three buckets, not one. Collapsing them into a single "guilty" or "innocent" is what produces a decade of people talking past each other.
Established and no longer seriously contestable
- A program of injectable supplements was run on the playing group across the 2012 season, organised by a sports scientist operating with the club's authority.
- Players signed consent forms for injections of substances and those forms asserted compliance with the anti-doping code.
- The club doctor was sidelined, the record-keeping was inadequate and the governance was, by the club's own review, a serious failure.
- The injections were not declared during anti-doping testing that season.
- CAS found, to comfortable satisfaction, that the players used Thymosin Beta-4, a prohibited substance and that finding survived to become final and binding.
- The club was separately convicted of an occupational health and safety breach.
Inferred by the tribunal, on the cable standard, rather than directly proven
- That the specific substance was TB-4 rather than another form of thymosin. This was a conclusion drawn from the body of evidence, not from a vial or a positive test.
- That all 34 players received it. The finding was made across the group rather than proven individually for each man.
- That the players were "significantly at fault." This is a judgement applying the Code's standard, not a finding that any player knowingly doped.
Genuinely unresolved or unknown
- The precise supply chain, vial by vial, from source to player. The panel itself declined to make a complete finding on this and did not need to.
- The exact dosing and frequency for each individual.
- What was in the mind of any individual official. No tribunal ever found that the senior coach, or any coach, knew the substances were prohibited. That question was not the subject of the doping case against the players and was never determined.
- The status of AOD-9604, a separate substance also used in the program, sat in genuinely contested territory at the relevant time. The compliance picture around it was murkier than the TB-4 question and advice about it was, on the record, conflicting. This ambiguity is real and should not be flattened.
Why the two versions diverge
If you hold those three buckets in mind, most of the public confusion dissolves. The people who say "they never tested positive, it was a stitch-up" are standing in the first bucket and ignoring that the Code never required a positive test. The people who say "they were drug cheats, simple as that" are treating the inferred bucket as if it were the proven one and ignoring that no individual intent was ever established. Both are reading one bucket and calling it the whole.
The record itself is more careful than either camp. It says: the governance failed, beyond argument. It says: a prohibited substance was used, established to the requisite standard and now final. It says: the players bore responsibility under a Code that holds them responsible regardless of who misled them. And it says, by its silence, that some things, including exactly what was administered to whom and what any official truly knew, were never nailed down and likely never will be.
That is where the findings stop. Everything past that point is no longer a matter of the reports. It is a matter of judgement and judgement is a separate conversation.
