Rugby: The fatal admission that sank Israel Folau's career

Israel Folau made a fatal acknowledgement on the first day of his code of conduct hearing, in what may have been the moment that sunk his rugby career.

According to the Daily Telegraph, Folau finally admitted he understood that his social media posts could offend people, after an intense cross examination from top lawyer Justin Gleeson SC.

After expertly avoiding the admission by repeatedly pointing back to the words from his social media posts being from the Bible, Folau's lawyers stunned Rugby Australia by admitting to a low-level breach of the player's code of conduct, reports the Telegraph.

Over the next few days of the hearing, Gleeson continued to grill Folau as to whether he could take his controversial post down and guarantee not to make a similar post in the future.

However, Folau could not guarantee either as he believed he would go to hell if he deleted the post.

"Izzy was getting told he'd go to hell if he took down the post," a source told the Telegraph.

"But if he had removed that image and re-posted word for word what the [Bible] verse says, they couldn't have sacked him."

At that moment, the case was essentially done: Folau had admitted to an offence, didn't want to rectify that offence, and couldn't offer any promises that he wouldn't repeat the offence.

The 30-year-old rugby star and his team are still considering their next steps, and one of them could include challenging Rugby Australia in the Supreme Court over his high-level breach of contract.

Another option could be taking up the case with the Fair Work Commission by lodging a complaint for unlawful dismissal on religious grounds. He will have until June 10 to begin that process.

Folau decided not to appeal through Rugby Australia's internal channels, saying that he feared he would receive unfair treatment during the process.

"My decision not to commence Rugby Australia's appeal process is in no way an acceptance of the judicial panel's findings," Folau said in a statement on last month.

"I simply do not have confidence in Rugby Australia's ability to treat me fairly or lawfully throughout this process."
