During the board meeting of the FEI on the 24th of June, it was agreed that the current doping rules will be adjusted. That is written in the summary of the meeting. The current rules we be evaluated an the definitive version will be send to the several National Federations on July 13th who can give their feedback.
Suspected is that the so called 'contamination' will be a point on the agenda. Federations get seven weeks to send their notes on the new rules and in October a final decision will be taken.
