The Supreme Court has ruled that the Mahon Tribunal must the pay the legal costs incurred by the wife of former Fianna Fáil TD, Liam Lawlor.
Hazel Lawlor successfully prevented the Tribunal from pursuing €430,000 in lands and property belonging to her late husband.
The Mahon Tribunal had been chasing legal costs against Liam Lawlor, who died in a car crash in Moscow six years ago.
Following a Supreme Court ruling last November, lawyers for the Tribunal said they could not oppose Mrs Lawlor's application for her costs.
