Once the date has been set, Rugby Australia and the New South Wales Rugby Union will not comment on the matter until the proceedings have wrapped up.
Folau had past year assured both Cheika and RA chief executive Raelene Castle that he would not make his views public again, which Genia said had now likely led to a total breach of trust.
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.
"If you've gone and said those things (walk away from the game) to (Wallabies coach Michael) Cheika and Raelene, there's a breach of trust and I guess there's an element of selfishness about it".
He wrote next to the Instagram picture, "Those that are living in Sin will end up in Hell unless you repent".
He signed an undisclosed new deal previous year, and made at least one list as the highest-paid rugby player in the world.
Woman 'Infatuated' with Columbine High School Massacre Found Dead
Saturday, April 20 marks the 20th anniversary of the Columbine tragedy, in which two students opened fire and killed 13 people. Police there said the parents aided in the investigation and provided valuable information that led investigators to Colorado.
The controversy started April 10 when Folau - who is known for his Christian faith - posted an image on Instagram that referenced Scripture and read, "Warning".
Folau has been stood down by the Waratahs, replaced at fullback by Kurtley Beale.
The 30-year-old's sporting career hangs in the balance following his latest homophobic social media post last week.
Hooper said in rugby it was traditional to accept your team-mates "warts and all" but he found it hard to ignore Folau's anti-gay views.
Following a service at the Truth Of Jesus Christ Church, he told the Sydney Morning Herald newspaper: "I share it with love".
She said Folau's comments have been misunderstood. "So it's tough but I am fairly confident we have got the depth in our squad to be able to cover him".
Folau signed a contract in 2015 that paid him almost $1.5 million USA per year. I certainly think it makes it a bit uncomfortable for people within both those teams and environments to sort of relate to him and, moving forward, maybe even play with him.
