Sanction

Four years' ineligibility for tampering, with no disqualification of results before 7 February 2024

The dispute

Mr. Katir missed an out-of-competition doping control at his registered address in Murcia on 28 February 2023. To explain the missed test, he gave the Athletics Integrity Unit (AIU) travel documents he had altered to show a flight on 28 February instead of 26 February, together with an explanatory letter (submitted on 9 and 29 March 2023). The missed test was still recorded, and in February 2024 he admitted a whereabouts violation (three failures in twelve months) and accepted a two-year ban. While that case was being handled, the AIU noticed that the flight date had been manipulated, and Mr. Katir admitted the falsification at an interview on 3 April 2024. Charged with tampering under ADR Rule 2.5, he received a four-year ban from the Disciplinary Tribunal. He appealed to have the sanction reduced; World Athletics cross-appealed for a five-year ban and the disqualification of his results from 9 March 2023 to 7 February 2024.

Key holdings

1. Tampering is established even though the filing failure was recorded anyway. Knowingly giving falsified documents to explain a missed test is intentional conduct that subverts the doping control process. ¶¶ 109–111
2. The tampering (March 2023) is not a separate second violation, because it was committed before Mr. Katir was notified of the whereabouts violation. The two are sanctioned together as a single first violation, based on the more severe sanction (ADR Rule 10.9.3). ¶ 117
3. No aggravating circumstances justify raising the ban above four years. ¶ 124
4. No exceptional circumstances justify a reduction. A confession made a year later, when confronted with strong evidence, does not reduce the athlete's fault. ¶¶ 127–128
5. Fairness exception applied. With no evidence that the athlete used prohibited substances, his results from 9 March 2023 to 7 February 2024 (the start of his provisional suspension) are not disqualified. ¶ 137
