"Israel has responded formally today to request a code of conduct hearing which, under the circumstances, was not an unexpected outcome", said RA CEO Raelene Castle.
Folau, who signed a new four-year contract back in February, was given 48 hours to accept the sanction or have the matter referred to a Code of Conduct hearing.
Castle said Folau was warned formally and repeatedly past year about the expectation of him as a Wallabies and Waratahs player in regards to his social media use, following similar controversial posts.
The hearing, before representatives of Rugby Australia, the professional players association and an independent figure, is likely to be delayed by a series of public holidays over the next two weeks, extending the headache for the sport's leaders in Australia.
"Israel has failed to understand that the expectation of him as a Rugby Australia and NSW Waratahs employee is that he can not share material on social media that condemns, vilifies or discriminates against people on the basis of their sexuality".
Hopoate made it clear which corner he was in with a crude and homophobic social media post of his own. "We appreciate that this particular matter will attract significant interest, but due process must be followed".
The fundamentalist Christian posted similar comments a year ago but escaped sanction and signed a new deal with RA through 2022 in February.
"Folau was on the front of the best known gay magazine in Australia promoting the cup", Owen said.
'But getting it out in that disrespectful manner publicly is not what our team is about. Everyone that is out there supporting us, we don't pick and choose'.
Speaking to the Guardian, chair of International Gay Rugby Ben Owen has praised the action taken to remove Folau's attitude from the game.
The devout Christian had shared similar sentiments in the past and was previously warned not to do so by Ms Castle.
Rugby Australia responded last week by announcing its intention to terminate Folau's multi-year, multi-million-dollar contract to play for the Wallabies and Super Rugby's NSW Waratahs.
Folau sparked outrage last week after posting to his Instagram account that "hell awaits drunks, homosexuals, adulterers, liars, fornicators, thieves, atheists and idolators" - adding they should "repent". "Jesus Christ loves you and is giving you time to turn away from your sin and come to him", the player wrote on Instagram on April 10, along with a series of biblical scriptures.
The star fullback also retweeted a story about Tasmania allowing gender to be optional on birth certificates.
