Denis O'Brien and IBRC have won High Court orders against RTE stopping the businessman's confidential arrangments with the bank being published or broadcast.
The details of Mr Justice Donald Binchy's decision cannot be reported until his written judgment is redacted of sensitive information next week.
Mr Justice Donald Binchy's orders stops any publication or broadcasting of Denis O'Brien's confidential banking arrangments with IBRC
Anymore than that cannot be said at this point until his judgment is redacted of sensitive information.
RTE's business editor had planned a report for the Six One News, focusing on governance at the State-owned bank.
It related to IBRC's handling of large debtors, one of whom was Denis O'Brien, and a letter the businessman sent in 2013 to the bank's special liquidator Kieran Wallace about the terms of his loan facilities.
While there was no allegation of wrongdoing against Mr O'Brien, he claimed revelations about his private banking would damage his commercial and banking interests.
In a statement this evening RTE said they are disappointed by today's ruling and will give further consideration to it.
He has secured the injunctions he was looking for, but the case still has to go to a full hearing.
Mr O'Brien issued a statement that said: "I am delighted with today's High Court decision which has refused permission to RTE to broadcast material which was illegally obtained about my private financial affairs.
"RTE came into possession of highly selective illegally obtained documents and took a decision to attempt to broadcast the details.
"I took this case to protect my rights as a citizen. I believe that every citizen is entitled to privacy in their financial affairs.
"I have been particularly encouraged by the number of people who have contacted me to communicate their belief that confidentiality in a customer-banking relationship is of absolute importance.
"I believe that the circumstances of today's decision should be a matter of the gravest concern for the RTE Authority as the national broadcaster."
