Belfast's High Court has granted permission for a judicial review into over 100 murders, including the Dublin and Monaghan bombings linked to loyalists in the 1970s.
Families of the victims have always argued there was an evidence of state collusion in the murders by a group known as the Glenanne Gang.
The judicial review is listed to commence on 7 May.
This morning's hearing before Mr Justice Tracy lasted less than two minutes.
It involved an application made by Edward Barnard; whose 13-year-old brother, Patrick, was one of four people killed by a bomb planted at the Hillcrest Bar in Dungannon in 1976.
