Media organisation are going to the High Court this morning to clarify if they can report comments made in the Dail about Denis O'Brien's banking arrangments with IBRC.

In the normal course, media reports of comments made by Catherine Murphy last week about his dealings would be covered by Dail privilege.

But in this instance there is uncertainty because of an existing High Court order prohibiting RTE and any media outlet on notice of the order, reporting details on the same subject.

Media organisations are going to court to clarify whether the terms of the order extend to the comments made in the Dail.
