"I confirm, as I outlined to you over the weekend, that one - his contract with the Cowboys has been terminated, and two - his registration in the game is no longer and I can't see a time, at any time, in the future that he will be welcomed back".
The NRL CEO delivered the damning condemnation at a press conference on Tuesday morning where he doubled down on his earlier comments about acting in the "strongest terms" when it comes to violence against women.
Shocking details have emerged into the alleged incident inside of Townsville's Ville Resort and Casino that was caught on CCTV, which was enough evidence to convince the Cowboys to sack Barba immediately.
"There was a physical altercation between the player and his partner", Greenberg said today.
Super League has slammed the door shut on reigning Man of Steel Ben Barba, who has been deregistered by Australia's National Rugby League.
"I don't think we have much choice ben, I think community expectations are clear and I think that onus and responsibility on our players is clear".
"I can't see a time, or any time in the future that he'd be welcome back".
In 2017, the RFL rejected an appeal by St Helens against a 12-match ban imposed by the NRL on Barba for cocaine use in the aftermath of Cronulla's 2016 NRL Grand Final triumph.
"This is an enormous outcome because this is a guy that now loses his livelihood and career in the game".
The Super League said it would uphold any penalty imposed by the NRL, meaning returning to England to play is not an option for Barba and while Greenberg said he won't call for a worldwide ban, he said the former Bulldogs and Sharks star should start looking for another job.
"I would expect anything in relation to a situation like that, that would stand, because when you're talking about issues at that level, we need to make sure the codes are supporting each other on that".
