It has a remit to investigate child abuse which occurred in residential institutions in Northern Ireland over a 73-year period up to 1995.A total of 13 institutions in Northern Ireland are currently under investigation by the Inquiry in relation to allegations of historical institutional abuse and/or neglect.In total, the inquiry is expected to hear from more than 300 witnesses during the course of the public evidence sessions.
