The act empowered the Lord Lieutenant of Ireland by proclamation to name a district within which the act would have force. The other provisions applied only with such "proclaimed areas".
The act allowed actions connected to agrarian violence to be tried as summary offences by a magistrate without a jury.[1] The "Mitchelstown Massacre" occurred on 9 September 1887, when Royal Irish Constabulary (RIC) members fired at a crowd protesting against the conviction under the act of two men, including MP William O'Brien.[1] Three were killed; when Balfour defended the RIC in the Commons, O'Brien dubbed him "Bloody Balfour".[6] On 6 May 1920, as the Irish War of Independence was escalating, it was reported to the Commons that "Between 1st November, 1918, and 30th April, 1920, 305 cases were dealt with under the Criminal Law and Procedure (Ireland) Act. 1,109 persons were prosecuted in these cases, 454 were convicted, 109 were discharged, 352 were ordered to find bail, 194 are awaiting trial."[7]
The act empowered the Lord Lieutenant to proclaim associations to be "dangerous" and to prohibit them. Under this power, the Irish National League was banned on 19 August 1887;[8] likewise the First Dáil on 10 September 1919;[9]Sinn Féin, the Irish Volunteers, Cumann na mBan, and the Gaelic League were proclaimed dangerous on 3 July 1918,[10] and banned in various counties between June and October 1919.[11][12]
Repeal
Bills to repeal the act were introduced regularly by Irish nationalist MPs.[13] In 1907, Michael Hogan proposed a motion in the Commons that, "in the opinion of this House, the presence of the Criminal Law and Procedure (Ireland) Act on the Statute Book is a gross violation of the Constitution, without parallel in any other portion of His Majesty's dominions, and that the Act should be immediately repealed."[14] It was supported on behalf of the government by Augustine Birrell, the newly appointed Chief Secretary for Ireland, and passed by 252 votes to 83.[14] A 1908 repeal bill passed second reading[15] and committee stage[16] in the Commons.
