The Ireland 2023 bid committee has rebutted any suggestion that it should step aside ahead of the vote on Nov. 15, saying such a move would undermine the process.
"There is in place a democratic process, whereby the council members of World Rugby, through their vote, are the ultimate arbitrators of who will host the 2023 Rugby World Cup," Spring said in a statement.
"To undermine this process in any way does a disservice to the entire structure.
"Ireland is now in dialogue with its many friends throughout world rugby and their initial response to us has been one of surprise at the evaluation report and its findings.
"As we have previously stated Ireland's team will compete to the final whistle as we bid to turn our historic bid plans into reality."
Ireland, who have never been the main host of the tournament before, were the bookmakers' favourites ahead of South Africa and France before this week.
