The second measure, the Offences against the State Act, made it possible for citizens to be interned without trial, and conferred elaborate powers of search, arrest and detention upon the Gardaí. It declared seditious any published suggestion that the elected Government of Ireland was not the lawful government. de Valera spoke about the IRA and its S-Plan in the Dáil for two hours, saying that that the IRA had no right to assume the title "Irish Republican Government" and that the Minister for Justice, P.
