Residents have objected to a liquor licence to serve alcohol at next month's rock concerts at Malahide Castle.
Depeche Mode, Paolo Nutini, Blur, Sam Fender, Florence and The Machine, Sting and Hozier will headline over seven nights from June 14– 30.
The concerts are expected to attract up to 20,000 people a night.
Promoters MCD had to apply to Judge Marie Quirke at Dublin District Court for an occasional licence to serve alcohol at the venue.
However, neighbours Mary Lynch and Nicola Byrne from Old Street and Majella Dunne, New Street, Malahide, jointly lodged objections.
Last year Ms Byrne and Ms Dunne took a similar course. However, Judge Quirke ruled that the event could get a liquor licence but four extra gardai had to patrol New Street and Old Street from 10.30 pm until 2 am for the seven concert nights.
Ms Dunne had claimed pedestrianisation of New Street and outdoor serving laws introduced in response to Covid-19 led to year-round street drinking and public order incidents.
"I feel now I am living in a beer garden", she had said. They cited fears it would cause problems in the area and that thousands of extra people would come into the village to drink before, during or after the concerts.
In the objectors' latest challenge, the residents contend there was one night of effective policing of street drinking last year.
Coolock Garda Inspector Oliver Woods outlined the policing strategy and said gardai would enforce public drinking by-laws. He had no objection to the licence and said there had been no problems in the running of the events.
About arrests in Malahide during the concerts last year, he said Swords and Howth experienced the same amount; gardai were doing their best, but when questioned by Ms Byrne, he conceded that a "zero tolerance approach" was unrealistic.
Most attendees would leave by Dart trains and various bus services. The court heard promoters engaged in a public consultation process advertised in the Irish Independent and the Northside People newspapers.
A Fingal County Council planner said the council allowed the concerts with 28 conditions and drinks not be served in the venue after 10 pm.
The case resumes next week when three residents are to give evidence supporting their objection.
The pedestrianisation of streets in Malahide is already the subject of a High Court challenge.
The three residents also have a licence objection pending before the district court concerning outdoor serving at three local pubs.
