Decision Details

A decision in the mater of UK Anti-Doping (UKAD) v Marc Shackley has been published by the National Anti-Doping Panel (NADP).

On 14 September 2021, Mr Marc Shackley, a Professional rugby football league player, provided a urine Sample Out-of-Competition. The Sample returned an Adverse Analytical Finding (AAF) for clenbuterol.

Mr Shackley was subsequently charged on 19 November 2021, with a breach of ADR Articles 2.1 and 2.2 for the Presence of a Prohibited Substance or its Metabolites or Markers in his Sample, and ​2.2 for Use or Attempted Use by an Athlete of a Prohibited Substance or a Prohibited Method. Mr Shackley admitted the Anti-Doping Rule Violations (ADRVs) but contested UKAD’s jurisdiction due to retiring from the sport. The NADP Tribunal, consisting of Mark Hovell ​(Chair), Dr Neil Townshend and Professor Gordon McInnes found Mr Shackley had committed the ADRVs pursuant to ADR Articles 2.1 and 2.2, and that he had not discharged the burden on him under ADR Article 10.2.1(a) to establish the ADRVs were not intentional. A period of Ineligibility of four years was imposed which will commence from 08 October 2021 and ends 11:59 on 07 October 2025.
