Where national policy requirements and imperatives lead a National Anti -Doping Organization to prioritize certain sports or discipline s over others in its test distribution planning (as contemplated by Article 4.4.1 of the International Standard for Testing and Investigations), the National Anti -Doping Organization may decline to consider advance applications for TUEs from Athletes in some or all of the non- priority sports  or disciplines , but in that case it must permit any such Athlete from whom a Sample is subsequently collected to apply for a retroactive TUE.
