At Gort District Court on Thursday, Judge Mary Larkin convicted the ex-horse trainer of the assault causing harm of farmer, John Hughes on a County Galway boreen in October 2020.
Judge Larkin also convicted Mr Mahon of producing a horse whip in the course of a dispute which was capable of inflicting serious injury and likely to intimidate another on October 13th 2020 at the same location at Newtown, Kilcolgan, Co Galway.
That charge is contrary to Section 11 of the Firearms and Offensive Weapons Act.
The court was told that there was “bad blood’ between 53 year old father of two Mr Mahon and Mr Hughes arising from a 2014 incident involving the two.
In June of last year, Mr Mahon formerly of The Ranch, Kilcolgan, County Galway but now living in Co Meath was given the longest ban at four years ever handed out to a trainer in Ireland for breach of animal welfare rules.
The Irish Horseracing Regulatory Board (IHRB) ban imposed was reduced by six months on appeal in September of last year.
In the case before Gort District Court, Mr Hughes told the court that on October 13th 2020 on his way back from herding cattle, Mr Mahon passed him on a horse on a boreen on Mr Mahon’s way to the way to the gallops
Mr Hughes said: “Mr Mahon went on six or seven yards and said what the f**k are you laughing at. He got down off his horse and asked what are you smiling at.
“He then left fly and hit me with the whip on the left hand side of the face just under my eye.”
Mr Hughes stated that the whip was 18 inches long and Mr Mahon hit him with the ball end of the whip. The whip with the red ball top was produced as a Garda exhibit in court.
Mr Hughes stated that Mr Mahon “then swung a second time. I put my hand up to protect myself and he got me on the knuckle and the left hand side of the face.
He added: “I then rushed him. My eye was weeping like hell at this stage. I pushed him against the gate and in doing so knocked a couple of stones off a pillar.”
Mr Hughes said that “there was a bit of a struggle” and Mr Mahon got free and kicked out at him twice.
Mr Hughes said that he has been left with a scar from a whip blow and pointed out the scar on his face to Judge Larkin.
Mr Hughes said that he has not spoken to Mr Mahon since 2014 and agreed that there was 'bad blood' between himself and Mr Mahon.
Mr Mahon denied that he assaulted Mr Hughes and in evidence alleged that Mr Hughes threw two rocks at him at the location.
In finding Mr Mahon guilty of the two offences, Judge Larkin said that it is not a case of one man’s word against another.
Judge Larkin said: “There is also the evidence of the injuries to Mr Hughes. They were viewed by Garda Phil O Donoghue on the day and they are consistent with Mr Hughes’s evidence.
Judge Larkin said: “I am satisfied that the incident did take place as described by Mr Hughes. I found him to be a credible witness and I found Mr Mahon to be vague and possibly inventive in relation to what he said about the incident.”
Counsel for Mr Mahon, Ernest White BL told Judge Larkin said that Mr Mahon “is an ex horse trainer as you may well know. He has lost his licence and he tells me his life has been turned upside down over the past year with the loss of his licence and his livelihood".
Mr White said that Mr Mahon has two children aged 7 and 11 and has moved back to Meath and is trying to get some work in the horse business.
Insp Brian Boland of Loughrea Garda Station told the court that Mr Mahon has 14 previous convictions but none relate to assault or public order. Insp Boland said that six relate to the Control of Dogs Act with the remainder relating to road traffic matters.
Mr White said that there has been no further incidents between the two men since October 2020.
Judge Larkin said that she would adjourn sentencing to allow Mr Hughes provide a victim impact statement to court.
Judge Larkin said: “I would be interested to know what the views of the injured party are and does he believe that this is all water under the bridge.”
Judge Larkin adjourned the case to October 27th for sentence.
