In Ireland, there are several kinds of public inquiry. A Tribunal of Inquiry, often simply called a tribunal, is a powerful type of statutory inquiry whose procedures are governed by the Tribunals of Inquiry (Evidence) Act 1921 as amended. An Oireachtas inquiry is a less powerful non-statutory inquiry controlled directly by the Oireachtas (parliament). A 2013 proposal to strengthen the power of Oireachtas inquiries was defeated at a referendum. The Law Reform Commission published a report in 2005 examining the operation of public inquiries and recommending changes. A commission of investigation is a different form of inquiry, with evidence generally given in private; provided by the Commissions of Investigation Act 2004 to address scandals relating to medical care and child abuse.
