The Titans immediatley launched an appeal against the punishment but on consideration, the judiciary’s ruling was upheld.
Titans managing director Michael Searle said the club was “disappointed” in the decision.
“While we are disappointed we were unsuccessful in convincing the chairman of the need to grant an appeal, we acknowledge that the process has allowed the club the chance to do so,” Searle told AAP.
“We stand firm in our support of William and his continued protest of innocence.
“However, we now consider the matter closed.”
