Despite a considerable requests and subsequent reminders, the Mexican Athletic Federation had repeatedly failed to provide the IAAF with the name and doping control form for an adverse analytical finding related to a doping control test on one of its athletes.This is strike one. Strike two is a fine, strike three is suspension of the federation (and therefore all its athletes).
I have no details on this story yet; your guess is as good as mine. Somebody flunked a dope test and there's a tug of war going on. The T&FN message board may eventually give us more info.
