Dublin city council has said it will take legal action if the DAA fails to comply with a court order to stop the dental unions’ operations in the city.
It is the latest blow to the DLAI, which has been criticised for allowing the unions to continue operating despite the threat of a legal challenge.
In a letter sent to the council on Friday, the DFA’s legal team said the legal challenge could have a “devastating impact” on the Dail, the Irish Parliament and the health service in general.
“The DLAIs activities have caused great harm to the health of residents in Dublin, the public health system and to the public purse,” the letter said.
“The DFA is prepared to take all appropriate steps, including seeking a judicial review of the Dáil order, to secure that the DSA is held accountable for its unlawful actions.”
A DFA spokesman said the union is “in the process of establishing a new legal team”.
“The legal process will now begin, with the intention of completing it as quickly as possible,” he said.
The DTAB, the health board’s body that represents dental workers, also said it was taking legal action against the DDAI and the DHA.
“We are in the process and are confident that we can put an end to this,” the DTAI said.
