The World Anti-Doping Agency says the Olympic drug cheat Nadzeya Ostapchuk will not receive a life ban.
The Belarussian shot-putter has received a four-year ban for failed drugs Test from the 2012 Olympic Games and a re-test of a 2005 sample.
Valerie Adams expressed her frustration that the IAAF didn't impose a lifetime ban.
Wada director general David Howman says the two tests were treated as one and therefore under International Athletics Federation rules a four-year ban is correct.
Howman says the rules didn't allow the IAAF to treat the 2005 failed test separately.
Howman says a new code coming into force next year will hand out heavier penalties and would hopefully overcome this issue.
