8.4 Where the request is for review of a TUE decision of an International Federation that   WADA is obliged to review, WADA may nevertheless refer the decision back to the International Federation (a) for clarification (for example, if the reasons are not clearly set out in the decision); and/or (b) for re- consideration by the International Federation (for example, if the TUE was only denied because medical tests or other information required to demonstrate satisfaction of the Article 4.2 conditions were  missing).
