The court could hear appeals by a defendant against conviction, sentence or both. Leave to appeal was only given where there was a disagreement on a point of law, although an exception can be made when new evidence becomes available which could not have been presented before the original court.
A further appeal to the Supreme Court only lay when the Court of Criminal Appeal itself or the Attorney General certified that a point of law of exceptional public importance needed to be resolved.
The Courts of Justice Act 1924 established a new court system under the terms of the 1922 Constitution of the Irish Free State. These included a new Supreme Court and High Court, and a Court of Criminal Appeal comprising judges of those two courts.[9] The courts were re-established in 1961 under the terms of the current (1937) Constitution.[10] The Court of Criminal Appeal was replaced on 5 November 2014 by the Court of Appeal, as mandated by the 33rd Amendment of the Constitution passed in 2013.[11][12][13][14] The Court of Appeal has taken on all hearings of the Court of Criminal Appeals and the Courts-Martial Appeal Court, as well as many backlogged Supreme Court cases.
