Minister for Justice Frances Fitzgerald said: "This is a day to thank the people of Ireland for their vote on May 22nd."
She said: "I am very privileged to be here today. This is an important step towards the enactment of the bill and I look forward to bringing this bill to the Seanad very soon and enacting this bill in the next few weeks."
Fine Gael TD Jerry Buttimer said it was a historic day.
Sinn Féin's Mary Lou McDonald congratulated Minister Fitzgerald and said: "This is a moment of joy in this chamber."
