In the unlikely event that the vote is a tie three ways, then South Africa will automatically go to the second round, and World Rugby president Bill Beaumont will have to eliminate either Ireland or France.
"There's a fine line between whinging and having justifiable concerns round the accuracy of what is contained in a report that World Rugby has placed so much store and weight‚" Browne told The Irish Examiner at the weekend. That invention involved William Web Ellis catching a ball during a game of football and running with it.
The second round saw France claim 24 votes to South Africa's 15 to be named hosts for a second time, after 2007.
Ireland dropped out in the first round of voting after only securing eight votes with France taking 18 and SA 13.
"They have a fiduciary responsibility at that meeting to act accordingly", Roux said.
As was to be expected, South African rugby lovers on Twitter exploded.
