Former Justice Minister Alan Shatter will have to wait to find out the result of his 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 TD Mick Wallace during a row about the quashing of penalty points on RTÉ's Prime Time.

The former minister claims his reputation suffered as a result of the finding.

Judge Jacqueline Linnane reserved judgment after she finished hearing the appeal at Dublin Circuit Civil Court this afternoon.
