Associated Evidence Record
Evidence for
Thomas Dekker’s Retested EPO Sample and the Tour de France Exclusion
Investigative question
What do the documented retest, team action, and Dekker’s own public statements establish about his 2007 EPO case, and what remains unverified about broader blood-doping allegations?
Event boundary
The packet covers the December 2007 out-of-competition sample, its 2009 retesting and confirmation, Dekker’s removal from the 2009 Tour de France team, and his public responses in July and September 2009. It does not establish the separate Fuentes or HumanPlasma allegations because the captured sources do not provide usable corroboration for those matters.

Claim ledger
| Item | Claim | Support | Qualification |
| Claim 1 | A December 2007 out-of-competition urine sample from Thomas Dekker was retested using newer methods and reported positive for EPO in 2009. | Dekker's counter-analysis positive for EPO — Cyclingnews, Dekker protests his innocence; L'Equipe hints at more doping - Monsters and Critics | The captured sources describe the laboratory result and retesting process; they do not provide the underlying laboratory file. |
| Claim 2 | Dekker’s counter-analysis confirmed the EPO positive. | Dekker's counter-analysis positive for EPO — Cyclingnews, Thomas Dekker (cyclist) - Wikipedia | Cyclingnews reports the counter-analysis confirmation; Thomas Dekker (cyclist) - Wikipedia independently summarizes the same result but is a Wikipedia triage source, not authoritative evidence. |
| Claim 3 | Silence-Lotto removed Dekker from its 2009 Tour de France team after the positive test was reported. | Dekker's counter-analysis positive for EPO — Cyclingnews, Dekker protests his innocence; L'Equipe hints at more doping - Monsters and Critics | The sources report the team action contemporaneously; the packet does not include a team disciplinary document. |
| Claim 4 | In July 2009, Dekker publicly protested his innocence and said he felt betrayed by the retesting of the 2007 sample. | Dekker protests his innocence; L'Equipe hints at more doping - Monsters and Critics | This establishes what Dekker said at the time, not that the positive result was erroneous. |
| Claim 5 | In September 2009, Dekker’s lawyer issued a statement saying that Dekker acknowledged making a mistake, accepted responsibility, and would apologize. | Dekker's counter-analysis positive for EPO — Cyclingnews, Thomas Dekker (cyclist) - Wikipedia | The statement was issued through his lawyer; it is a public admission and accountability statement, not a detailed account of every instance or substance used. |
| Claim 6 | Dekker described the EPO use in the September 2009 statement as a one-time mistake. | Dekker's counter-analysis positive for EPO — Cyclingnews, Dekker protests his innocence; L'Equipe hints at more doping - Monsters and Critics | This is Dekker’s characterization of his conduct. It should not be treated as proof that the use occurred only once. |
| Claim 7 | At the time of the sample collection, Dekker was riding for Rabobank. | Dekker's counter-analysis positive for EPO — Cyclingnews, Thomas Dekker (cyclist) - Wikipedia | This establishes team affiliation during the sample period, not team knowledge, authorization, or institutional involvement. |
| Claim 8 | The captured material does not substantively document a verified link between Dekker and the Fuentes blood-doping files or the HumanPlasma investigation. | Dekker's counter-analysis positive for EPO — Cyclingnews, Dekker protests his innocence; L'Equipe hints at more doping - Monsters and Critics | The absence of usable corroboration in this packet is not proof that no such link existed; ↑ "Boogerd and Dekker questioned about HumanPlasma doping scandal". Velonation.com. Retrieved 12 June 2012. is a non-substantive technical failure and DPG Media Privacy Gate is only a privacy-gate capture. |
Evidence assessment
The captured evidence supports a restrained account of Thomas Dekker’s 2007 EPO positive: a retested sample was reported positive, the counter-analysis confirmed the result, Silence-Lotto removed him from its Tour team, and Dekker later accepted responsibility while describing the use as a one-time mistake. The proposed Fuentes-files framing should not be retained because the only captured source tying Dekker to Fuentes is Wikipedia, while the other potentially relevant captures are non-substantive or inaccessible. The packet therefore passes only after reframing around the documented EPO case.
