A man, 32, has been charged with causing the deaths of a father and son in a crash two days after Christmas.
Ivan Petrov of Newry Road, Armagh appeared at Newry Magistrates Court.
His left arm was in a cast and he was wearing a brace around his waist.
Mr Petrov faces two charges of causing death by dangerous driving.
He is accused of causing the deaths of 63-year-old Peter Devlin and his 28-year-old son Loughlin at Killylea Road near Armagh on Friday 27 December.
They were part of a family group on a day out when their Mercedes car was involved in a collision with an Audi jeep shortly before 1pm.

Police were alerted to the collision by an automatic crash notification linked to a mobile phone app.
A woman remains in a critical condition in hospital.
Another woman and a baby who were in the car were also treated for their injuries but have since been released from hospital.
As well as the charge of causing death by dangerous driving, Mr Petrov is also charged with causing grievous bodily injury by dangerous driving.
The court was told that police believed the Audi jeep he was driving had crossed the road and hit the Mercedes the Devlins were travelling in on a left-hand bend.
A PSNI constable said she believed she could connect Mr Petrov to the charges.
She said he had told investigating officers that he was a diabetic and that prior to the crash he had felt his blood sugars were low.
Mr Petrov had stopped in Armagh to eat a chocolate bar and believed he had been OK to then continue driving.
The court heard he had no recollection of the crash.
Police objected to bail on the basis that Mr Petrov was a potential flight risk.
The court was told he had links to the Republic of Ireland.
Bail was refused and the defendant was remanded in custody to appear again on 21 January.
