1. The CAS has jurisdiction pursuant to Rule 21 of the IAAF Rules which provides that all the appeals to the CAS be made within sixty days of the date of communication to the prospective appellant of the decision that is to be referred. When a national federation issues several decisions related to the same case, any activity or decision which goes beyond stating that the previous decision is final and therefore untouchable constitutes a new decision. The last decision considered as final by the national federation starts a new time period for appeal under the IAAF Rules.
