The inquiry into the murder of solicitor Rosemary Nelson is scheduled to set a date for full hearings this week.
The panel hearing the inquiry say they intend to begin early next year, but want to consult all parties at a preliminary hearing today before setting a firm date.
Today's case management hearing - which could continue tomorrow - will consider any procedural issues so the inquiry can be "taken forward as rapidly and efficiently as possible", according to a statement.
The inquiry into Mrs Nelson's murder was set up in 2004 after a recommendation by retired Canadian Supreme Court Justice Peter Cory, who reviewed a number of alleged collusion cases.
The solicitor was killed by a loyalist bomb in her car on March 15, 1999, as she drove from her home in Lurgan.
