Dublin City Council is to appeal the High Court order directing it to assume responsibility for accommodating the residents of the Priory Hall apartment complex.
The residents were ordered to vacate the development last month following an application by the City Council's fire authority to the High Court.
The fire authority said there were serious fire-safety concerns about the development and there was a risk that if a fire broke out in one apartment it could spread within minutes to the entire building.
Residents, including many with young children, were accommodated in hotels and those who own apartments have now been provided with accommodation sourced by the council from NAMA and a housing trust.
The court directed that the city council meet the cost of the accommodation.
It also ordered that if residents who were on rent supplement had to pay more rent as a result of having to move from Priory Hall, the city council would make up the difference.
This evening, the City Council issued notification that it intends to appeal Mr Justice Nicholas Kearns's order directing it to provide accommodation for the evacuated residents.
The City Council will claim that the High Court President erred in ordering the City Council to assume responsibility for accommodating them.
And it will claim that he did not have jurisdiction to do this under the Fire Services Act.
The case is due back before the High Court tomorrow afternoon.
New Beginning, a group who represent more than 80 residents of Priory Hall, described this evening's development as very unwelcome.
In a statement, the group said the residents' only hope was the judge.
New Beginning described Dublin City Council's attitude as inhumane, and it said it further compounded the suffering of residents at a most uncertain time in their lives.
Last week developer Thomas McFeely and his company Coalport were ordered off the site after the court found he had breached the order directing him to carry out works to fix problems at Priory Hall within a certain timeframe.
Mr Justice Kearns said last week that he hoped the city council would evaluate the situation as a matter of urgency and that a solution could be found as quickly as possible.
