Michael Seme says he does not have details but learned from Semenya's lawyers that she can compete. Her lawyer, Greg Nott, was not immediately available to comment.
However, IAAF spokesman Nick Davies says "we are still in the same position as before - no official IAAF comment until we have finished the inquiry."
Davies said he couldn't say how long the inquiry will take.
Hours before the 800 final, the IAAF said it had ordered gender tests to be conducted because of Semenya's muscular build and rapid improvement in times. Her future as a runner has been in doubt since.
