Justice Minister Alan Shatter will be given the details today of 16 individuals who allege that they have been seriously mistreated by the Gardaí, the Garda Ombudsman and the judicial system.

Justice4All say many of these cases concern serious injustices, ranging from boundary disputes to murder.

The group, which includes TDs Luke Ming Flanagan, Mick Wallace, Clare Daly and Joan Collins, is calling on the Garda Ombudsman Commission to be reformed, as they believe it is not independent.

Deputy Flanagan said that there needs to be a proper mechanism in place to remove those who abuse their powers.

"People have to have faith in the justice system, and the vast, vast majority of guards are decent people, the vast majority of solicitors and judges are decent people," he said.

"But the problem is we don't have a mechanism in this country to weed out the ones who are not as good as the vast majority."
