[3][4][5][6][7] In 2002, Gilligan was tried and acquitted of the murder of the investigative journalist Veronica Guerin, who was reportedly working on a tip-off from an Irish politician who was also prominent in equestrian circles.
On 30 January 2006, the High Court cleared the way for the CAB to proceed with an application to have the equestrian centre and other property that belonged to the Gilligan family handed over to the state.
In January 2008, making a court appearance in an attempt to stop the state from selling off his assets, Gilligan accused John Traynor of having ordered the murder of Veronica Guerin.
In November 2012, the courts cleared the final barriers allowing the CAB to sell off the equestrian centre and Gilligan's house at Weston Green, Lucan.
[8] In July 2014, after a lengthy challenge, a Supreme Court ruling brought the CAB one step closer to selling off the house adjoining the equestrian centre, retained by Gilligan's wife, as well as additional properties in Blanchardstown and Lucan.
[citation needed] On 23 August 2018, Gilligan was arrested as he tried to board a flight from Belfast International Airport to Spain with more than €22,000 in a suitcase.
