Well, it's no surprise Court of Sport Arbitration (CAS) found "Rodchenkov evidence is hearsay with limited probative value&

CAS #88 wrote:... the IOC DC fundamentally erred in its application of the relevant legal framework to the facts of the Sochi Appellants’ cases. In particular, rather than seeking to determine whether the specific requirements set out in the relevant provisions of the WADC have been made out in individual cases, the IOC DC took a generic and “broad brush approach” to its assessment of the evidence. It proceeded from a foregone conclusion and applied assumptions and circular inferential reasoning to reach its ultimate conclusion that the Sochi Appellants were each guilty of ADRVs.

1. The IOC DC began by assuming the existence of an institutionalised system to protect certain doped athletes during the Sochi Games. This assumption, however, was based solely on the “contradictory and untrue” allegations made by Dr. Rodchenkov. Notwithstanding that, the IOC DC’s reasoning proceeded on the assumption that Dr. Rodchenkov’s allegations were true and accurate.

2. The IOC DC further assumed, again on the basis of Dr. Rodchenkov’s allegations, that particular individual athletes were involved in the scheme of institutionalised doping. It proceeded on that assumption despite the absence of any conclusive evidence connecting individual athletes to the scheme.

3. On the basis of those two assumptions, the IOC DC concluded that the individual Sochi Appellants must each have (a) used the Duchess Cocktail; (b) provided clean urine to be used to replace dirty urine samples with clean ones; and (c) communicated the number of their doping control samples at the Sochi Games to the persons who were responsible for tampering with, and substituting the contents of, the samples provided by the Sochi Appellants during the doping control process.

“not hearing Dr Rodchenkov before a proper Disciplinary Commission or Hearing Panel [...] is convincingly probable to be contested before a Court as being not compatible with the principles of international law, Swiss procedural law and in particular with article 6 § 1 of the European Convention for the Protection of Human Rights regarding the right to a fair process” (Decision of the IBSF Doping Hearing Panel in the matter of Aleksander Tretiakov dated 18 December 2017, para 53).

1. The McLaren Reports are merely the views and conclusions of one person based on a compilation of unverified witness testimony, documents and forensic analyses.

2. The McLaren Reports expressly make it clear that the reports are not intended to assess whether any individual athletes have committed an ADRV. Since the McLaren Reports were published, Prof. McLaren has confirmed repeatedly that the reports were not intended, and did not seek, to investigate potential ADRVs by individual athletes.

3. In any event, there is no indication that the findings contained in the McLaren Reports have been verified or tested since they were published. Prior to the proceedings before the CAS, the Sochi Appellants have had no opportunity to question Prof. McLaren. The contents of his reports must therefore be considered “a mere manifestation of Professor McLaren’s personal views”.

... neither Prof. McLaren nor the investigations conducted by the IOC have revealed any evidence that the Athlete actually consumed any Prohibited Substance.

Although Dr. Rodchenkov alleges that the Athlete was a “protected athlete” and was therefore authorised to take the Duchess Cocktail, he also confirmed that he never personally witnessed any athletes consuming that “cocktail”. Accordingly, Dr. Rodchenkov’s testimony is mere hearsay, which should be disregarded.

Dr. Rodchenkov’s testimony ... has been contradictory. As noted above, according to the First McLaren Report, Dr. Rodchenkov’s original evidence to Prof. McLaren stated that an FSB agent was present at each doping control station at the Sochi Games and was responsible for sending the DCFs to Ms. Rodionova, for onward transmission to Dr. Rodchenkov. In a later statement recorded in the Second McLaren Report, however, Dr. Rodchenkov changed his account to one where it was the athletes, rather than an FSB agent, who transmitted pictures of their DCFs to Ms. Rodionova.

Dr. Rodchenkov was rarely present in the Sochi Laboratory and, on the few occasions when he was present, “he was often drunk”. Mr. Kudryavtsev went on to say that, more generally, Dr. Rodchenkov drank alcohol and took drugs on a regular basis, suffered from “mood swings” and liked to tell “unbelievable” and “colourful” stories. Mr. Kudryavtsev suggested that Dr. Rodchenkov “crav[ed] recognition and attention” and “was willing to do absolutely anything for financial gain."

Dr. Rodchenkov was frequently drunk during the Sochi Games and did not spend much time at the Sochi Laboratory. Moreover, after Dr. Rodchenkov left Russia in 2015, he contacted Mr. Chizhov several times via Viber. Dr. Rodchenkov acted in a “very strange” manner during those calls; for example, by asking Mr. Chizhov to remind him how they had swapped samples in Sochi because Dr. Rodchenkov had forgotten. Mr. Chizhov said he had the impression that Dr. Rodchenkov was “drunk or under the influence of psychotropic substances”.

Dr. Rodchenkov suffered from “constant mood swings” and had a tendency to say strange and fantastical things. Mr. Krotov made a number of further allegations concerning Dr. Rodchenkov’s conduct and character. These included assertions that Dr. Rodchenkov was “crazy about money” and “keenly interested in sex”.

prior to the Sochi Games, Dr. Rodchenkov had ordered “everybody” to create an email account on the Gmail platform and to provide Dr. Rodchenkov with the usernames and passwords for those accounts.

Dr. Rodchenkov’s story of what allegedly happened at the Sochi Games was inconsistent, untrue, and cannot have occurred as he claims. Dr. Rodchenkov had no first-hand knowledge of the vast majority of the alleged facts and evidence he had sought to describe. His entire story, at best, was based on the alleged stories of others; “He, himself, has no clue what was going on”.

622. There were numerous inconsistencies regarding what allegedly happened in the Sochi Laboratory. These included: (a) the times at which Dr. Rodchenkov received the photographs of the DCFs; (b) how he came to learn the identities of the athletes whose samples needed to be swapped; (c) his statement that he destroyed all evidence of the DCFs from his phones (and instructed others to do the same), while keeping a diary relating to the events in question; and (d) who was taking and sending the photographs of the DCFs.

623. Other aspects of Dr. Rodchenkov’s story defied logic, including: (a) how the sample bottles were transported around the Sochi Laboratory – i.e. hidden in the laboratory coat of Mr Kudryavtsev; and (b) his account of rinsing the sample bottles (in a room which had no running water) and depositing the urine into a large plastic tub and proceeding to empty the tub into a toilet, which was situated next to the main entrance and security booth of the Sochi Laboratory, on a frequent basis.

There was no contemporaneous evidence in support of Dr. Rodchenkov’s story. His diary entries, which recorded him going to bed by midnight almost every night during the Sochi Games, would prove that his whole story of nighttime swapping was fabricated.

625. Further, five witnesses who were there at the relevant time had given evidence that Dr. Rodchenkov’s account was fiction; they were credible witnesses, unlike Dr. Rodchenkov.

Frankly, to my resolutely non-legal mind, based on these two judgements, the CAS arbitrators – Christoph Vedder, the President, Hamid Gharavi and Dirk-Reiner Martens – are to be congratulated.

They seem to have made every effort, most properly in my view, to follow the evidence that was presented to them, while endeavouring to shut out the overheated geopolitical atmosphere still enveloping any issue pertaining to Vladimir Putin’s Russia.

Thanks to the 154-page Arbitral Award concerning Russian cross-country skier Alexander Legkov versus the International Olympic Committee (IOC), and the 165-page award covering Russian bobsledder Aleksandr Zubkov’s case against the same adversary - among the most significant CAS rulings of recent times – I now know:

That Russians consume "on average one or two grams more salt per day than Europeans";

That there is a landmark proceeding in the field of how evidence from crime scenes might become contaminated known as, "the infamous Phantom of Heilbronn case"; and

Far more than I would ever have wished to know about "the possibility of male DNA contaminating a female athlete’s urine sample as a result of sexual activity between the man and woman".
