 D'Arcy has been a prominent supporter of Seán Quinn (once Ireland's richest billionaire) and his family in their court battles with the Irish state.D'Arcy controversially spoke at a rally in July 2012 in protest against the High Court finding Sean Quinn Jnr and his cousin Peter Darragh Quinn were found in contempt of court for not complying with its order to produce the €451 million they had moved out of the state while owing it to the state.While Seán Jnr served his prison time, Peter Quinn (who was found in contempt on the basis of evidence including a video-tape of him in the Ukraine detailing the crime) became a fugitive and is currently at large in D'Arcy's pastoral area of Enniskillen
