Three men have been found guilty of falsely imprisoning and intentionally causing serious harm to Kevin Lunney, a director of Quinn industrial Holdings.
A fourth man who stood trial before the Special Criminal Court - 68-year-old Luke O'Reilly, with an address at Mullahoran Lower, Kilcogy, Co Cavan - was acquitted.
It took Mr Justice Tony Hunt over five hours to sum up the relevant evidence heard during the 40-day trial and to outline the reasoning behind the court's verdicts.
In the end, three of the accused were found guilty for their roles in what happened to Mr Lunney after he returned home from work on September 17th 2019.
Early in the trial, Mr Lunney described how he was bundled into the boot of a car and taken to a horse trailer - where he was tortured and repeatedly told to resign.
After returning to his home in Co Fermanagh, Mr Lunney claimed he was dragged out of his car and forced into the boot of an Audi vehicle.
From the stand last June, he said he was then transported to what he believed to be a horse box - where he claims he was stripped to his boxer shorts and doused in bleach before being beaten with a stick and attacked with a knife.
His leg was broken and he said the letters 'Q-I-H' were carved into his chest.
Throughout his ordeal, he claimed he was repeatedly told to step down from his role at Quinn Industrial Holdings.
A man, who cannot be named by court order, was found to have inflicted most of the injuries.
Two others - Alan O'Brien (40) and Darren Redmond (27) - both from East Wall in Dublin, were also convicted for their roles.
A fourth man was acquitted.
In a statement Mr Lunney thanked everyone who worked on the case and also expressed his "sincere gratitude" to the wider community for their assistance.
A sentence hearing for the three convicted today will take place later this month.
