In an effort to improve the impact of my communication further (and just for fun), I asked ChatGPT (understanding that ChatGPT can get things wrong), whether Houlihan's 4-year sanction was "unjust". It gave me two answers: 1) according to the letter of the WADA Code, no, but 2) from a scientific and fairness standpoint, there is a strong case to say that Houlihan was unjustly sanctioned.
I think that answer nicely captures the divide that has existed since publication of the CAS report. Can we rely on the CAS report findings as something that is also scientific and fair?
Question:
Was Shelby Houlihan unjustly sanctioned for 4 years because the source of the nandrolone was not identified?
ChatGPT response:
That’s the central ethical and scientific question in the Shelby Houlihan case — and it cuts to the heart of how anti-doping enforcement balances strict liability with scientific uncertainty.
Let’s answer it directly and carefully.
❓Was Shelby Houlihan unjustly sanctioned for four years?
⚖️ Under the letter of anti-doping law (WADA Code):
No — the sanction was formally justified under WADA’s strict liability principle:
Athletes are responsible for any banned substance found in their body, regardless of how it got there.
To avoid sanction, they must prove the source and demonstrate lack of fault or negligence.
Houlihan could not prove how the 19-NA entered her body.
Under those rules, a 4-year ban for an adverse analytical finding (AAF) of a non-specified substance like nandrolone is standard when no mitigating source is proven.
So from a procedural standpoint, the sanction aligns with WADA rules.
🧬 But from a scientific and fairness standpoint?
Yes — there is a strong case to say Houlihan was unjustly sanctioned, because:
✅ 1. The source of the nandrolone was never identified
No synthetic nandrolone was found.
No long-term metabolites were presented that proved injection or oral doping.
The IRMS test indicated "exogenous" origin — but:
WADA TD2021NA clearly states that IRMS cannot determine origin if an athlete consumed intact boar offal.
Shelby Houlihan claimed to have eaten a burrito that may have included such meat.
So while her story may have been judged "unlikely" by CAS, scientific evidence did not exclude that possibility — and WADA’s own technical documents affirm that IRMS cannot do so.
✅ 2. The IRMS result does not prove doping in cases involving boar meat
TD2021NA explicitly says:
"In such cases, the GC/C/IRMS test cannot otherwise determine that the origin is exogenous."
This directly applies to Houlihan's case. If her 19-NA level was below 15 ng/mL (it was), and if she plausibly consumed boar offal (she claimed she did), then IRMS cannot establish doping. That’s WADA’s own position.
✅ 3. No behavioral, biological, or circumstantial evidence of doping was presented
No known doping program, pattern of performance, or prior suspicious test results.
No motive (she was already a top-level athlete).
No synthetic metabolites or administration markers were identified.
No pattern of microdosing or masking was alleged.
The entire case hinged on a single urine sample, with a metabolite profile that — by WADA’s own documents — could come from food.
✅ 4. The standard of proof in practice may have failed to account for scientific uncertainty
While the burden was on Houlihan to prove the source, the legal presumption against her functioned in tension with known scientific ambiguity. This creates a potential injustice:
Athletes must prove a negative (i.e., they didn't intentionally dope),
Even when WADA’s own science says the result could come from a non-doping source.
This is where many scientists and legal scholars argue that the strict liability standard can yield unjust outcomes, especially in cases like hers, where:
The substance is known to occur naturally in food,
The IRMS test cannot resolve origin, and
The athlete cannot reasonably prove the full supply chain of every meal.
🧾 Final Answer:
Yes, from a scientific and ethical standpoint, Shelby Houlihan was likely unjustly sanctioned for four years, because:
The source of the nandrolone was never identified,
The evidence did not prove intentional or synthetic use,
And the testing methods used (particularly IRMS) are acknowledged by WADA itself to be insufficient in cases involving possible boar offal ingestion.
The sanction was procedurally correct under WADA’s rules, but that does not mean it was just.
