Fingal County Council has said that it is not responsible for the more than 50 Roma adults and children who have been encamped at the M50 roundabout in Ballymun for almost two months.
A spokesperson said that the council 'has no role in removing these people [the extended Rostas family] from the roundabout at Sillogue'.
'They are not considered to be Travellers under the legislation which we have responsibility for enforcing,' she said.
The spokesperson added that the council was satisfied that the issue was one of immigration and not social housing, and was therefore the responsibility of the Department of Justice.
She said that the local authority is in regular contact with the Department of Justice, the HSE and gardaí on this issue.
It emerged earlier that three of the Roma children are now being cared for by the Health Service Executive.
Yesterday, campaigners for social justice said the Roma people were living in horrific conditions and that they feared an outbreak of disease at the camp.
Concern was also raised about reports that the families had been subjected to racist abuse and that eggs had been thrown at them.
