Mick Wallace says he's waiting to see if Alan Shatter will go to the High Court before deciding on whether he'll take a civil case against the former Minister for damages.

Wallace was speaking after Mr Shatter lost an appeal against a finding that he breached data protection law.

Last May, the Data Protection Commissioner ruled that Mr Shatter unlawfully divulged personal information about Mick Wallace, when he revealed on RTE's Prime Time that the Independent TD had been cautioned for using his mobile phone while driving.

Today in the Circuit Court, Judge Jacqueline Linnane upheld the ruling - saying it was her view that the Data Protection Commissioner had considered the matter fully.

Mr Wallace says he's considering his options as to whether he'll take a case against Mr Shatter.
