The family of two children who were left orphaned by a fire at a halting site in Carrickmines are suing Dun Laoghaire Rathdown County Council.
The blaze, on Glenamuck Road in October 2015, which claimed the lives of 10 people, was described as the worst to happen in Ireland since the Stardust tragedy in 1981.
Michael and Tom Connors, who are nine and seven years old respectively, lost their parents Tom (28) and Sylvia (30) in the blaze, along with their siblings Jim (5), Christy (3) and six-month-old Mary Connors.
The boys are being raised by their grandparents Josie and Jim.
According to the Irish Times, Josie Connors is suing the council on behalf of her grandchildren Michael and Tom.
The paper reports that she confirmed that her solicitor had lodged papers in the High Court against the council, indicating her intention to take action against the council.
A spokesperson for Dun Laoghaire Rathdown County Council told Dublin Gazette: “We cannot comment on ongoing legal proceedings.”
