The IMC's remit included: • monitoring any continuing activity by paramilitary groups. • monitoring the commitment by the British Government to a package of security normalisation measures. • handling claims by parties in the
Northern Ireland Assembly that a Minister, or another party in the Northern Ireland Assembly, is not committed to non-violence and exclusively peaceful and democratic means, or that a Minister has failed to observe any other terms of the pledge of office, or that a party is not committed to such of its members as are or might become Ministers observing the other terms of the pledge of office. The IMC submitted formal reports to both the
British Government and
Irish Government. The body faced criticism from
Sinn Féin due to the manner in which it was set up as an apparent sop to Unionists. In a debate in
Dáil Éireann Aengus Ó Snodaigh referred to it as "three
spooks and a lord".
Sinn Féin issued legal proceedings against the IMC, through their solicitors in London,
Howe & Co, alleging that the IMC Commissioners are "apparently biased" and challenging the IMC's application (or non-application) of a standard of proof in its assessments and reports presented to the two Governments. The IMC issued 22 reports, including 3 ad hoc reports. Two ad hoc reports were issued on the initiative of the IMC, while one (the 19th) was requested by both state governments. ==Commissioners==
