Lawyers for Denis O'Brien have begun an application for an injunction to stop RTÉ broadcasting details of his banking arrangements with IBRC.

High Court judge Mr Justice Donald Binchy has agreed to put in place reporting restrictions for the duration of the hearing.

The High Court has heard the report by RTÉ's business editor David Murphy was supposed to go out on the Six One news on May 1 but it is on hold.

Businessman Denis O'Brien contends the story breaches his privacy rights by giving details of his loan facilities with state owned bank IBRC.

Opening the case his barrister Michael Cush asked why Mr O'Brien was named in the report when RTÉ says the focus of the piece is on the governance of IBRC rather than the personal finances of his client

IBRC has joined Mr O'Brien in making this injunction application. The case resumes tomorrow.

Reporting restrictions are in place – as one of the affidavits contains the script of the RTÉ report at the centre of the row.
