Victims of the Waterford sports coach will attend the motion on the terms of reference for the commission on Thursday afternoon.
Retired Circuit Court Judge Barry Hickson will examine the handling of allegations of child sexual abuse made against Bill Kenneally.
Jason Clancy says they will be sitting in the gallery on Thursday.
He told WLR News that this is the final part of the jigsaw and it’s very important that it’s passed through the Seanad.
It will then go into the Dail the following week to be passed there and then it goes back to the cabinet the following week
to be rubberstamped for the commission to commence it’s work.
He says all the hard work that they have done and all the campaigning over the last couple of years has come down to this.
