The role of a Commission of Investigation

A commission of investigation provides a less expensive and speedier method of investigating matters of urgent public concern than a tribunal.

The Government can set up a commission of investigation based on a proposal by a minister, with the approval of the Minister for Finance.  The Houses of the Oireachtas must approve a draft of the order establishing the commission, and a statement of the reasons for establishing the commission must be laid before each House.



The Commissions of Investigation Act 2004 gives the commission the power to conduct its investigation in any manner it considers appropriate, as long as it adheres to the Act and the commission’s rules and procedures.  It must seek and facilitate the voluntary co-operation of people whose evidence it requires, and it must conduct its proceedings in private, except in exceptional circumstances.

A commission is entitled to compel witnesses to give evidence.  It can also direct a person to provide it with any documents in the person’s possession or power relating to the matter under investigation.  If the person fails to comply, the commission can apply to the court to compel compliance; or it may impose a costs order against the individual for the costs incurred by all other parties arising from the delay.

A commission of investigation reports to a specified minister.  The minister is obliged to publish the commission’s final report unless the minister considers that such publication might prejudice any criminal proceedings that are in progress.  In such a case, the minister may apply to the High Court for directions.
