World Cup 2023: 'Dialogue is now closed'
Last week, the World Cup board said South Africa should be chosen after they gave it an overall rating of 78.97, compared with 75.88 for France and 72.25 for Ireland, across a range of criteria.
Friday's announcement from World Rugby's Dublin headquarters said the complaints "do not impact on the detail or outcomes of the evaluation report nor on the subsequent recommendation".
World Rugby chairman Bill Beaumont added "the window for dialogue is now closed".
The World Rugby Council will make the final decision when it votes in London on November 15.
In a letter seen by AFP this week, Irish Rugby Football Union Chief Executive Philip Browne complained to World Rugby Chief Executive Brett Gosper saying Ireland's scoring has "suffered unreasonably relative to the scoring for other bidders".
"There are very clear examples in recent times of starkly empty stadia in South Africa for significant fixtures," Browne said in his letter.
"The evaluation report does not appear to address this in any meaningful way," he added.
He also raised the issue of security.
"Was an independently recognised, world-class security organisation used to review the underlying security situation within each bidding country… if not, why not?" he asked.
The evaluation report also prompted a furious response from Bernard Laporte, president of the French Rugby Federation (FFR), who said the body would be writing to Beaumont seeking corrections over a series of inaccuracies, including the quality of stadiums and hotels ahead of the final vote.
"We are not rated as well over doping because they tell us that we are too strict," Laporte told AFP last week.
"On security, we have the same number of points even though there are 52 murders a day in South Africa.
Having repeatedly insisted, in the face of the criticisms, that its processes had been transparent and fair, global rugby chiefs said in its statement on Friday that they had addressed the "clarification" requests.
"World Rugby can confirm that it has addressed in full, clarification requests by the Rugby World Cup 2023 host candidates and Council members," the statement said.
"The ability to submit clarification requests following the publication of the recommendation and comprehensive report on 31 October was agreed and permitted within the host selection process operated by World Rugby.
"These clarifications have been addressed with significant supporting detail, and have been shared with the host candidates and World Rugby Council," added the statement, saying they reflected "transparent principles" and "do not impact on the detail or outcomes of the evaluation report nor on the subsequent recommendation".
Meanwhile former England captain Beaumont thanked the host candidates for their "feedback", adding "in order for Council to have appropriate time to consider all the materials, the window for dialogue is now closed".
"We now look forward to Council making its decision in London on November 15."
Both South Africa, in 1995, and France, in 2007, have previously staged the World Cup outright, while Ireland are bidding to be the main hosts for the first time.
The increasingly fractious atmosphere between the Ireland and South Africa bid teams adds an extra edge to their Test match in Dublin on Saturday.
Ireland coach Joe Schmidt will hope his players lay into their Springboks opponents as robustly as the Irish Rugby Football Union's CEO Philip Browne did in a letter this week to his World Rugby counterpart Brett Gosper about South Africa's topping the technical review that puts them in pole position to carry the day in the vote next Wednesday.
Schmidt, though, says he is not going to tell the players of the significance of beating the South Africans on the pitch with regards to the vote although he appeared to relish the thought of landing a blow days ahead of the vote.
"I hadn't thought about it and I don't want to put any more pressure on us," said the New Zealander.
"Gee, though, wouldn't it be great to put a really good performance in and put Irish rugby in the shop window ahead of the vote?"
