A 23-year-old man was allegedly found by gardai with a knuckleduster in a southside car park.
Ian Brophy (23) is facing trial in the Circuit Court after the matter was deemed to be too serious for the District Court.
The defendant, of Rathminton Close in Tallaght, appeared before Tallaght District Court accused of possession of a silver-coloured knuckleduster.
The alleged incident took place at the Old Mill car park in Tallaght on April 12 last year.
The State solicitor said the book of evidence was ready and had been served on the defendant, who goes forward to the next sittings of Dublin Circuit Criminal Court.
Judge Bridget Reilly gave Brophy the alibi caution, warning him he had 14 days to provide to the State details of anyone he proposed calling as a witness in his defence. Judge Reilly remanded the defendant on bail in his own bond of €400.
The judge assigned defence solicitor Lorraine Stephens and one junior counsel on legal aid.
