The Supreme Court has indicated that it will hear a case relating to a series of police raids throughout the country in 2007.
Some of those arrested in the raids face a variety of charges under the Arms Act. Five others are charged with participating in a criminal group.
In a judgment issued on Wednesday the Supreme Court says it will hear an appeal relating to evidence that the Crown wishes to produce at the trial.
That hearing will take place on 3 and 4 May.
On Tuesday the Court of Appeal upheld an earlier High Court ruling that the trial of those arrested during the raids should be heard before a judge sitting alone, rather than before a judge and jury.
The trial is scheduled to begin in late May.
