The Private Members' Bill on abortion has been defeated in the Dáil by 109 votes to 20.
The Technical Group had put forward the Bill to legislate for the 1992 ruling of the Supreme Court in the X-case and make abortion legal for pregnant women whose lives are at risk.
Patrick Nulty - who has already lost the party whip - was the only Labour TD to support it.
Fianna Fáil voted against and Sinn Féin in favour.
During the debate, Sinn Féin's Mary Lou McDonald said her party supported the Bill but was not in favour of what is termed "abortion on demand".
