Paul Brady, A farmer from county Tyrone, appeared in Dungannon Crown Court last week, accused of contributing to the death of his father.
Brady is accused of driving a tractor dangerously, which resulted in the death of his father.
His father, Phelim, died following a road collision between the tractor his son was driving and a Truck back in June 2014.
Phelim was standing on the draw bar of his son's tractor when the collision occurred, leading to the dangerous driving charges against Paul.
The accident occured on the A4 dual-carriageway near Dungannon.
The accused, Brady, also faced charges of driving without insurance AND driving while being disqualified.
The driver of the turck, William Murphy, of county Down also appeared in court on the day.
He told the court how he had slowed down upon approaching the tractor from behind on the road, and sped up to overtake only for a car from behind to overtake him, causing the accident.
The prosecution told the court that the truck had been travelling at 90 km per hour upon impact, and said the truck driver had failed to safely accomodate his speed to avoid impact upon being overtaken by another car.
Paul Brady said that he had warned his father against standing on the drawbar whilst the tractor was driving, but he insisted.
Both men, Brady and Murphy, were accused of dangerous driving on the day, a charge denied by both men.
The case is set to be continued through the week.
