In October 2022 the Athletics Integrity Unit (AIU), on behalf of World Athletics, reported an anti-doping rule violation against the Kenyan Athlete Ibrahim Mukunga Wachira after his sample tested positive for the prohibited substances 19-norandrosterone (Nandrolone) and Tamoxifen.

Following notification a provisional suspension was ordered and the Athlete filed a statement in his defence. He explained with evidence that he underwent medical treatment in a clinic in Kenya for his knee injury and that Nandrolone injections had been administered.

The AIU had requested assistance from the Anti-Doping Agency of Kenya (ADAK) to investigate the Athlete's explanations. Hereafter ADAK's investigations confirmed that the Athlete underwent treatment in this clinic.

In May 2024 the AIU charged the Athlete with an anti-doping rule violation and thereupon the he failed to respond. The AIU determines that the his medical treatment could not explain the presence of Tamoxifen in his sample and that there are aggravating circumstances present in this case.

Because the Athlete did not respond within the set deadline the AIU determines in June 2024 that the Athlete was deemed to have waived his right for a hearing and accepted the consequences. In addition the AIU establishes that he had had failed to sign and submit the Admission of Anti-Doping Rule Violations and Acceptance of Consequences Form.

Therefore the AIU decides on 17 June 2024 to impose a 6 year period of ineligibility on the Athlete, starting on the date of the provisional suspension, i.e. on 4 October 2022.

In March 2024 the Athletics Integrity Unit (AIU), on behalf on World Athletics, reported an anti-doping rule violation against the Kenyan Athlete Elias Kiprono Kemei after his sample tested positive for the prohibited substance Trimetazidine.

Following notification the Athlete timely admitted the violation, waived his right for a hearing, accepted a provisional suspension and the sanction proposed by the AIU.

The Athlete explained that he he had used the substance while he was unaware that it was prohibited. Because he had timely admitted the violation he received a 1 year reduction from the AIU.

Therefore the AIU decides on 17 June 2024 to impose a 3 year period of ineligibility on the Athlete, starting on the date of the provisional suspension, i.e. on 19 March 2024.

In October 2023 the International Tennis Federation (ITF) reported an anti-doping rule violation against the American tennis player Casey Kania after his A and B samples tested positive for the prohibited substance Cannabis.

In this case there were delays in the proceedings attributed to the Athlete because he did not respond timely or properly. Ultimately the Athlete admitted the violation, waived his right for a hearing and accepted the sanction proposed by the ITF.

The Athlete denied the intentional use of Cannabis and explained with limited evidence that he had used a product on the advice of his family doctor without a prescription. The ITF deemed that the violation was not intentional and considers that there have been delays in the proceedings attributed to the Athlete.

Therefore the ITF decides on 2 February 2024 to impose a 2 year period of ineligibility on the Athlete, starting on the date of the decision.

In December 2023 the Anti-Doping Agency of Kenya (ADAK) reported an anti-doping rule violation against the Tanzanian bodybuilder Obadia Andabwile Mwampeta after his sample tested positive for the prohibited substances 19-norandrosterone (Nandrolone), and Stanozolol.

Following notification ADAK was unable to locate the Athlete and he failed to respond. Thereupon the case was referred to the Kenya Sports Disputes Tribunal and a decision was rendered based on the written submissions of the Parties.

In view of the evidence the Panel finds that the presence of multiple prohibited substances have been established in the Athlete's sample and accordingly that he committed an anti-doping rule violation. 

Without the Athlete's response the Panel deems that he failed to demonstrate that the violation was not intentional, nor how the substances had entered his system. Furthermore the Panel finds that there are no grounds for a reduced sanction.

Therefore the Panel decides on 2 May 2024 to impose a 4 year period of ineligibility on the Athlete, starting on the date of the decision.

In December 2023 the Anti-Doping Agency of Kenya (ADAK) reported an anti-doping rule violation against the Tanzanian bodybuilder Erick Kanshumba after his sample tested positive for the prohibited substances 19-norandrosterone (Nandrolone), Boldenone, Boldione, Mesterolone and Metenolone.

Following notification ADAK was unable to locate the Athlete and he failed to respond. Thereupon the case was referred to the Kenya Sports Disputes Tribunal and a decision was rendered based on the written submissions of the Parties.

In view of the evidence the Panel finds that the presence of multiple prohibited substances have been established in the Athlete's sample and accordingly that he committed an anti-doping rule violation. 

Without the Athlete's response the Panel deems that he failed to demonstrate that the violation was not intentional, nor how the substances had entered his system. Furthermore the Panel finds that there are no grounds for a reduced sanction.

Therefore the Panel decides on 2 May 2024 to impose a 4 year period of ineligibility on the Athlete, starting on the date of the provisional suspension, i.e. on 26 December 2023.

In December 2023 the Anti-Doping Agency of Kenya (ADAK) reported an anti-doping rule violation against the Athlete Caroline Jepchumba Kigen after her sample tested positive for the prohibited substance Testosterone.

Following notification ADAK was unable to locate the Athlete and she failed to respond. Thereupon the case was referred to the Kenya Sports Disputes Tribunal and a decision was rendered based on the written submissions of the Parties.

In view of the evidence the Panel finds that the presence of a prohibited substance has been established in the Athlete's sample and accordingly that she committed an anti-doping rule violation. 

Without the Athlete's response the Panel deems that she failed to demonstrate that the violation was not intentional, nor how the substance had entered her system. Furthermore the Panel finds that there are no grounds for a reduced sanction.

Therefore the Panel decides on 23 May 2024 to impose a 4 year period of ineligibility on the Athlete, starting on the date of the provisional suspension, i.e. on 26 December 2023.

• AAA 2017 No. 01 17 0003 4443 USADA vs Gil Robers
  July 10, 2017
• CAS 2017_A_5296 WADA vs Gil Roberts
  January 25, 2018

In October 2023 the United States Anti-Doping Agency (USADA) reported an anti-doping rule violation against the Athlete Gil Roberts after his sample tested positive for the prohibited substances Enobosarm (Ostarine), LGD-4033 (Ligandrol), RAD140 and SR9009.

Previously in June 2017 the Athlete established No Fault or Negligence when he tested positive for Probenecid. However in December 2022 he accepted a 16 month period of ineligibility for the presence of the prohibited substances Andarine and Ostarine.

Following notification a provisional suspension was ordered. The Athlete filed a statement in his defence and he was heard for the New Era Arbitration Tribunal.

USADA contended that the test result was valid and that the presence of multiple prohibited substances had been established. Accordingly USADA deemed that the Athlete intentionally had committed a third anti-doping rule violation.

The Athlete denied the intentional use of these substances and requested for a reduced sanction. Yet, he could not explain how these substances had entered his system.

He asserted that after the previous cases he was targeted by USADA and he disputed the UCLA Laboratory and the validity of the test result. Further he claimed that he was denied an opportunity to have his B sample tested.

The Sole Arbitrator assessed and addressed the evidence and the issues raised by the Parties and determines that:

• There were no departures of the ISL in the analysis of the Athlete's sample.
• The Athlete failed to provide any evidence that the UCLA Laboratory had departed from the ISL.
• The Athlete did not request that his B sample be opened and analysed within the set deadline.
• There is no evidence that he was subject to excessive testing as a form of retaliation or harassment on the part of USADA.
• The Athlete committed a second anti-doping rule violation and there are no grounds for a reduced sanction.
• The Athlete failed to establish that the violation was not intentional, nor how these substances had entered his system.

Therefore the Arbitration Tribunal decides on 18 June 2024 to impose an 8 year period of ineligibility on the Athlete, starting on the date of the provisional suspension, i.e. on 17 October 2023.

In July 2023 the United States Anti-Doping Agency (USADA) reported an anti-doping rule violation against the swimmer Kensy McMahon after her A and B samples tested positive for the prohibited substance Vadadustat (AKB-6548).

Following notification a provisional suspension was ordered. The Athlete filed a statement in her defence and she was heard for the New Era Alternative Dispute Resolution Arbitration Tribunal.

USADA contended that the Athlete failed to establish that the violation was not intentional. She also did not demonstrate with corroborating evidence how the prohibited substance had entered her system.

The Athlete accepted the test result and denied the intentional use of the substance. She asserted that she carefully checked the products she ingested and that she had been tested multiple times without issues.

After the positive test 18 medications and supplements had been analysed in laboratories and the Athlete also filed the results of a polygraph test and a hairtest. However the presence of Vadadustat was not detected in these 18 products in question.

Moreover she suggested that the substance entered her system through ingestion from some form of unknown environmental contamination. Also she speculated that, during competition in Italy, one of cups used at the chaotic free-for-all feeding station contained Vadadustat. 

The Sole Arbitrator assessed and addressed the Parties' evidence and determines that:

• The presence of a prohibited substance has been established in the Athlete's samples.
• She committed an anti-doping rule violation.
• She failed to establish how Valdadustat entered her system.
• Unknown environmental contamination and alleged ingestion at the feeding station in Italy is mere speculation.
• The polygraph evidence gives little weight and the hair analysis has no relevance in this case.
• The Athlete is not a cheat, nor is there evidence that she acted intentionally or recklessly.
• She failed to demonstrate with corroborating evidence that the violation was not intentional.

Therefore the Arbitration Tribunal decides on 31 May 2024 to impose a 4 year period of ineligibility on the Athlete, starting on the date of the provisional suspension, i.e. on 7 July 2023.

In August 2023 the Canadian Centre for Ethics in Sport (CCES) reported an anti-doping rule violation against the Brazilian football player Joao Morellin after his sample tested positive for the prohibited substance Clomifene. Following notification the Athlete filed a statement in his defence.

The Athlete's provided an explanation for the presence of Clomifene in his sample. Hereafter in April 2024 he failed to provide additional explanations to the CCES.

In view of the Athlete's explanation and based on his degree of fault CCES proposed a reduced sanction. Thereupon in May 2024 the Athlete failed to dispute the violation within the timelines specified in the CADP and the Notice of Charge.

Therefore the CCES decides on 11 June 2024 to impose an 18 month period of ineligibility on the Athlete, starting on 8 May 2024.

In October 2023 the Anti-Doping Agency of Kenya (ADAK) reported an anti-doping rule violation against the Athlete Rosemary Chelangat after her sample tested positive for the prohibited substance Erythropoietin (EPO).

In view of the evidence the Panel finds that the presence of a prohibited substance has been established in the Athlete's sample and accordingly that she committed an anti-doping rule violation. 

Without the Athlete's response the Panel deems that she failed to demonstrate that the violation was not intentional, nor how the substance had entered her system. Furthermore the Panel finds that there are no grounds for a reduced sanction.
