The Taoiseach has told the Dáil that allegations that a former judge abused his power with a woman who was before his court "is a very serious issue".
Speaking during Questions on Promised Legislation, Micheál Martin said he will consult with others on "how we deal with this".
He was replying to Solidarity-PBP TD Paul Murphy, who raised the issue under Dáil privilege.
Mr Murphy had said to the Taoiseach: "On the 14th of July, I raised with you the gross abuse of power by retired Kerry judge James O'Connor.
"I explained how he had abused his position to persistently and completely inappropriately pursue a woman - a vulnerable woman - who was before his court on a family law matter for a sexual relationship.
"Over the summer I was contacted by another woman who told me a very similar story relating to the same judge.
"She was again before him on a family law matter. He approached her repeatedly, he got her number, and then he persistently pursued her.
"There were multiple incidents. I won't go through all of them. I'll just quote one incident she told me about.
"She said: 'He rang me another day and said he had stuff for my case. He told me to meet him at the back door of the courthouse. I went to the back door. He was waiting. He said he didn't have the paperwork with him. He brought me in there to get the paperwork. Then he lunged at me. I pushed him and left. He obviously felt he could have done anything he wanted to'."
Mr Murphy said: "There is clearly a repeated pattern of abusive behaviour by James O'Connor, the question is what is the Government going to do to stop this sort of thing happening again."
In response, the Taoiseach said the "first case" involving the judge "went to GSOC".
However, they had been unable "to bring this to the conclusion that one would anticipate it should be", Mr Martin told the Dáil.
"I am very concerned", he said, adding that he will "give further consideration to this".
