Robert Fogarty, aged 44, from Cardy Rock Court, Balbriggan, Co Dublin, had been charged earlier with possessing a meat cleaver as a weapon.
Yesterday, Judge Cormac Dunne ordered Mr Fogarty to appear next week when CCTV evidence will be viewed at Dublin District Court.
The judge has to rule on whether the case is to stay in the jurisdiction of the district court or instead go forward to the circuit court which has wider sentencing powers.
The court has already heard that it is alleged the man had the knife while travelling on a bus at Atrium Road, Dublin Airport, on the night of January 27 last.
A garda sergeant has told Judge Dunne that it would be claimed Mr Fogarty was highly intoxicated when he got on the bus. It was alleged that he asked the driver to pull up at a “non stop” but when the driver did not, Mr Fogarty “produced a meat cleaver from his backpack and swung it at the driver who was behind protective glass”.
Mr Fogarty, who has not yet entered a plea, was remanded on continuing bail.
