World Rugby was “unfair” to referee Craig Joubert by saying he was wrong to award Australia a late, match-winning penalty against Scotland, according to Wallabies coach Michael Cheika.
The governing body issued a statement on Monday saying the South African had not made the “appropriate decision”.
Cheika, whose side won Sunday’s match 35-34, said: “No other referee has had this stuff put out there like that.
“I would have liked my mates to back me up a little more.”
Former top referee Jonathan Kaplan, who has mentored Joubert during his career, questioned whether World Rugby should be “criticising one if its own assets”.
Scotland were leading by a point when Jon Welsh was ruled deliberately offside in the 78th minute for playing the ball after a knock-on by a team-mate.
Joubert awarded the penalty, which outside-half Bernard Foley kicked to win the game, but World Rugby said the Wallabies should have been awarded a scrum instead because their scrum-half Nick Phipps had touched the ball.
“I genuinely feel for Craig Joubert,” added Cheika, whose team will play Argentina in the semi-finals on Sunday. “It’s so unfair.
“I have never seen that before. I am not sure why the decision had to be publicly reviewed and put out there.
“I really hope his fellow referees stand by him because, well, the fact I’m not allowed to say much about it says it all.”
After the match, Scotland coach Vern Cotter said the television match official (TMO) “would have taken away any doubt”.
But World Rugby said Joubert was not allowed to refer the decision as regulations only permit the use of the TMO on foul play or to determine the legitimacy of tries and kicks.
