The Dáil unanimously approved an all-party motion calling on the British government to establish a full, independent and public judicial inquiry into the murder in 1989 of Belfast solicitor Pat Finucane.
Minister for Foreign Affairs Dermot Ahern said that the inquiry planned under the 2005 UK Inquiries Act was "not acceptable to the family, to this Government, to the committee of ministers in Strasbourg, nor to the many international human rights groups who support the Finucane case".
Fine Gael leader Enda Kenny said it was "vital that the elected representatives of the Irish people send a clear message to the British government and wider audiences on the issue of a murder which rocked Northern Ireland when it took place".
Labour's foreign affairs spokesman Michael D. Higgins said it was a "necessary function" of our Government to ensure that its British counterpart complied with its international commitments.
