Terrorism and Speech
In The State (Lynch) v Cooney [1982] IR 337, the Supreme Court upheld the validity of a statutory provision [section 31(1) of the Broadcasting (Authority) Act, 1960 (also here) as amended by section 16 of the Broadcasting Authority (Amendment) Act, 1976 (also here) – thankfully repealed in 2001] which allowed the Minister to preclude from broadcast any matter which “would be likely to promote, or incite to, crime or would tend to undermine the authority of the State”. O’Higgins CJ for the Court held that the free speech guarantee [Article 40.6.1(i)] of the Constitution
…enables the State, in certain instances, to control these rights and freedoms. The basis for any attempt at control must be, according to the Constitution, the overriding considerations of public order and morality. The constitutional provision in question refers to organs of public opinion and these must be held to include television as well as radio. It places upon the State the obligation to ensure that these organs of public opinion shall not be used to undermine public order or public morality or the authority of the State. It follows that the use of such organs of opinion for the purpose of securing or advocating support for organisations which seek by violence to overthrow the State or its institutions is a use which is prohibited by the Constitution.
