People before Profit TD Bríd Smith has described the reaction of Fine Gael and members of the legal profession to comments she made in relation to the ruling of a high court judge as "hysterical".
Ms Smith said what she had said in the Dáil and on social media was a matter of public record and information that was "readily out there".
She said she was criticising a judgment that had huge and threatening implications for many thousands of workers.
Deputy Smith said she believed the ruling was seriously flawed and she said it was an example of judgments that prioritise property and employer rights over worker's rights.
She said these originated from the class bias of a judiciary that was composed of a particular section of our society and she stood over this.
Yesterday evening, Minister for Justice Charlie Flanagan wrote to the Ceann Comhairle of the Dáil to ask him to take appropriate steps in relation to comments made in the house by Ms Smith about the judge.
He is also understood to have written to the Chief Justice, Mr Justice Frank Clarke.
Ms Smith made comments in the Dáil and posted a meme on Facebook criticising high court judge, Mr Justice Garrett Simons, following a judgment given by him on Tuesday in which he found that legislation allowing for legally enforceable pay and conditions to be set for thousands of workers, particularly in lower paid roles, was unconstitutional.
The judge found against the State parties in the case - they have 21 days to decide whether or not to appeal.
In his letter to Ceann Comhairle Seán Ó Fearghail, Minister Flanagan said he was gravely concerned by what he described as a highly personalised, inappropriate and inflammatory attack on a high court judge.
He said it trespassed on the separation of powers and represented an attack on democracy itself.
Ms Smith's comments were also strongly criticised by the Council of the Bar of Ireland and the Law Society of Ireland.
