The Commission on the Future of Policing in Ireland is holding its first meeting today.
The 12-member body was set up to conduct a root and branch review of Garda operations, following a series of scandals.
The controversies included the recording of nearly a million fake breath tests by Gardaí.
The commission is chaired by Kathleen O'Toole, the chief of the Seattle Police Department.
It is due to issue a report by September next year.
