A man allegedly tried to steal a bicycle from a six-year-old boy who was out riding it with his father.
Stephen Klitz (55) is alleged to have pushed the child to the ground, where he hit his head.
Judge Anne Watkin refused jurisdiction to deal with the case in the district court and adjourned the matter to a date next month for the preparation of the book of evidence.
The accused, of Sarsfield Park, Lucan, appeared before Dun Laoghaire District Court charged with assault and att- empted theft.
The incident allegedly took place at Albert Road Lower, Glenageary, last April 18.
The court heard that the Director of Public Prosecutions had directed summary disposal of the matter in the district court.
Outlining the allegation for jurisdiction purposes, Gda Daniel Cuffe alleged that Mr Klitz tried to take a bicycle from a six-year-old boy.
Gda Cuffe alleged that Mr Klitz pushed the boy to the ground, where he hit his head, but he did not suffer any injuries.
The garda said the boy's father tried to intervene and stop Mr Klitz, who allegedly had a small knife in his bag at the time.
Judge Watkin was asked by defence lawyer Kim Moloney to consider Mr Klitz's state of mind at the time, but she said she could not do so.
The judge said she did not consider it to be a minor matter, when the allegation was that an adult tried to take something by force from a child.
She refused jurisdiction to deal with the case in the district court.
Sgt Peadar McCann asked for an eight-week adjournment for the preparation of the book of evidence.
Ms Moloney said there was consent to the adjournment.
Mr Klitz has not yet indicated a plea to the charges.
