It means that RA could have sacked him immediately without any hearing.
It means Castle has cost RA a shitload of money with this hearing (and no doubt a future challenge/appeal by Folau), and left themselves wide open to an appeal based on what constitutes a breach of "code of conduct". That would mean back to another hearing (or courts if he takes it that far), to argue that a social media post based on fact and his faith, is not a breach of their code of conduct.
Rugby AU Code of Conduct:
https://www.rugbyau.com/about/codes and policies/integrity/code of conduct
28 pages of vague information.
Only problems he might have are: Part 2 (Code of Conduct) Section 1 (Code of Conduct - Players).
Subsection 1.3:
Treat everyone equally, fairly and with dignity regardless of gender or gender identity, sexual orientation, ethnicity, cultural or religious background, age or disability. Any form of bullying, harassment or discrimination has no place in Rugby.
Subsection 1.7:
Use Social Media appropriately. By all means share your positive experiences of Rugby but do not use Social Media as a means to breach any of the expectations and requirements of you as a player contained in this Code or in any Union, club or competition rules and regulations.
So he could challenge on those grounds that his message was not bullying, harassment, nor discrimination, and therefore did not breach the expectations and requirements of him as a player, therefore not breaching the player Code of Conduct.
I sense this is about to get real messy (and expensive)
