In a letter to Reddy last week, Cheikh Thiare, director of the executive office of the IAAF president, said Sascoc had failed to inform the international athletics body that all 11 ASA board members had been suspended. He called on Sascoc to explain the suspensions.
"I spoke to him about two weeks ago when he wanted clarity on the whole process," Reddy said.
"The letter basically asks for an update of the process after my last conversation with him.
"I've put that together with the input of Zola Majavu in terms of what is uncovered, what is paid for up to now, and the hosting of the African Junior Championships, which was also a concern when I spoke to him."
Majavu was appointed as the interim ASA administrator last month, with Sascoc giving him 120 days to assist the embattled federation in clearing up its mounting debt.
Thiare said the IAAF wanted copies of the Sascoc board resolution on April 12 and the minutes of the Sascoc general assembly on April 13.
"We would also ask you to provide us with a clear statement of the grounds that Sascoc considered it had to take the action that it did, together with all supporting documents and evidence," Thiare told Reddy in the letter.
Reddy said the reply with all the supporting documents would be sent to the IAAF on Wednesday.
"We are engaging with the IAAF as we have done previously and all they are looking for is an update of the process," Reddy said.
Reddy said Evans remained suspended and was not allowed to represent himself as ASA president.
"As much as he writes on an ASA letterhead, it is now illegal in terms of what he is doing," he said.
"He is misrepresenting himself and the country, and the IAAF is fully aware that he and his board members are suspended in terms of leading ASA."
The IAAF said it would not reveal its position on the suspensions of the board members until Sascoc had responded to the letter.
"We nonetheless draw to your attention at this stage the provisions of article 4.1 of the IAAF constitution that make it clear that the IAAF only recognises national governing bodies that have been democratically elected in accordance with their constitutions," Thiare told Reddy.
According to article 4.1 of the constitution: "A national governing body (including its executive body) which has not been so elected, even on an interim basis, shall not be recognised by the IAAF."
However, Reddy said he was taken aback by the inclusion of the clause in the letter.
"I was surprised by the clause because I had spoken to him two weeks before that, except it was a telephone conversation and I think now they are looking for some kind of update in writing."
