Sir Declan Morgan, chief commissioner of the Independent Commission for Reconciliation and Reconciliation in Northern Ireland, has informed members of Parliament that the body might process up to 650 cases once new legislation is enacted.
The commission's head appeared before the Northern Ireland Affairs Committee to outline potential operational requirements ahead of parliamentary consideration.
Since commencing operations in 2024, the organisation has already incurred expenditure amounting to £65m.
Morgan cautioned that the financial scale of future investigations could reach approximately £630m depending on the scope of cases accepted under proposed reforms.
The committee is currently examining how the legacy body will function within its statutory framework before finalising any regulatory adjustments.
No confirmation has been given regarding whether the current reform proposals will be adopted or if alternative legislative pathways will be pursued.
Further details on the specific nature of these cases remain under review by the relevant authorities.
The Northern Ireland Affairs Committee will continue its scrutiny of the matter in light of the evidence provided.
