A 43-year-old man has been sent forward for trial at the Central Criminal Court, charged with the murders of his sons, Eoghan and Ruairi Chada.
Sanjeev Chada, with an address at Ballinkillen, Bagenalstown in Co Carlow, was before Castlebar District Court in Co Mayo.
Detective Sergeant Gary Walsh gave evidence that he presented the book of evidence to the accused this morning.
Mr Chada is charged with the murders at Skehanagh Lower, Ballintubber, Co Mayo on 29 July this year.
He did not speak during the brief court hearing. He nodded when asked by Judge Mary Devins if he understood the charges outlined to him.
Mr Chada has been remanded in custody.
An application for one junior counsel and one senior counsel to be provided for the accused through free legal aid was granted.
No date has yet been fixed for his trial.
Mr Chada was late arriving for court, after the Prison Service van transporting him took a wrong turn.
When the case was first called, Judge Devins was informed the accused was not in court.
She expressed concern that somebody charged with murder was not in attendance at the appointed time.
Mr Chada arrived into the courtroom at 11.15am. The Prison Service driver explained that he had taken a wrong turn between Roscommon and Castlebar, which took him off-course.
Judge Devins inquired as to whether the Prison Service had access to satellite navigation technology and said she was not impressed with the late arrival.
