Northern Ireland Human Rights Chief Commissioner Monica McWilliams is to face new pressure to back demands for a full cross-border inquiry into the Omagh bomb atrocity.
Victims relatives are to meet her in Belfast for the first time next month, a day after they hold talks in Dublin with the Garda Commissioner Noel Conroy.
Families of the dead and wounded have already been told by Prime Minister Tony Blair that any public investigation must wait until all criminal prosecutions are out of the way.
They believe the backing of Ms McWilliams who replaced Professor Brice Dickson three months ago is crucial in their campaign for a full hearing which will involve evidence being taken in the Republic as well.
The relatives met with Prof Dickson seeking the Commission's backing in August 2004, but they are still waiting for a decision.
Michael Gallagher whose son Aidan ( 21) was among the 29 people killed in the August 1998 attack - they included a mother pregnant with twins - said he was disappointed there had been no pledge of support.
They are also pressing the Republic's Human Rights Commission to give its backing as well.
Mr Gallagher said: "The human rights of the people of Omagh who were affected by the bomb must be protected. They need to learn the truth of what happened.
"Given the amount of work the Commission is involved in, I'm angry there has been no positive response. We've waited for well over a year and still we have no decision. It's a shame."
A date for the meeting had been agreed for earlier this month, but had to be cancelled as the families' request. It will now go ahead on January 20th.
A spokesman for Ms McWilliams said: "We look forward to consulting with the group on how best we can address their concerns."
Meanwhile it could be the second half of next year before the man accused of the 29 murders stands trial.
Sean Hoey (36) of Molly Road, Jonesborough denies all the charges and others connected with the Real IRA attack. No date or venue has been fixed.
The hearing is expected to last several weeks.
A separate High Court civil action with the families claiming £14 million sterling compensation from the five men they believe responsible for the bombing is also going ahead. But it too may have to be delayed until after the Hoey verdict is delivered.
