The SDLP will today demand Taoiseach Bertie Ahern puts pressure on the British government to drop plans for legislation which could see on-the-run suspects avoid prosecution.
SDLP leader Mark Durkan has insisted that the Bill would let paramilitaries and rogue army members off the hook.
He is due to meet Mr Ahern along with a party delegation at Government Buildings in Dublin.
"We will be raising our demand for the withdrawal of the NI Offences Bill which lets state killers off the hook," a party spokesman said last night.
"We want to see it replaced by a process which serves truth and victims.
"We will also be raising the need for full protection of human rights in community restorative justice schemes; pushing our North South agenda; and looking at strategies to get the Good Friday Agreement up and running in its entirety."
Under the Bill, those suspected of unsolved crimes during the Troubles can avoid going to jail by applying to a certification commissioner. Following the application on-the-run paramilitaries, rogue members of the police and army and other people suspected of crimes before 1998 may be granted a licence guaranteeing they will not be prosecuted for involvement in certain crimes.
But if they offend again their licence may be revoked and they could be sent to jail.
