At the tribunal on 22 October 2009, the prosecution did not ask for a ban, but rather for a "principal restraint" of the facts that they were being accused of, and as such it was expected that this would not cause any problems for either athlete. However, on 5 November 2009, the decision of the tribunal was announced: an effective one-year ban for both players.
