All three candidates (France, Ireland and South Africa) have to by July 31st submit the signed host agreement and the signed guarantee letters, in person to the World Rugby head office in Dublin.
The candidates will on September 25 each make a presentation to the World Rugby Council.
The Board of Rugby World Cup Ltd, based on the evaluation process, will in mid-October issue a recommendation to World Rugby Council as to who should be the 2023 hosts.
The World Rugby Council will vote to determine the host on November 15.
How the vote works:
It is a straight majority vote. If no country gets a majority in the first round of voting then the country with the least number of votes at that point is eliminated. In the event of a split decision, the chairperson, has the casting vote.
There are 37 votes and 19 votes will ensure a winner. None of the three bidding countries can vote.
