Red Light: A “red light” institution has at least one policy that both clearly and substantially restricts freedom of speech. A “clear” restriction is one that unambiguously infringes on what is or should be protected expression. In other words, the threat to free speech at a red light institution is obvious on the face of the policy and does not depend on how the policy is applied. A “substantial” restriction on free speech is one that is broadly applicable to important categories of campus expression. For example, a ban on “offensive speech” would be a clear violation (in that it is unambiguous) as well as a substantial violation (in that it covers a great deal of what would be protected expression in the larger society). Such a policy would earn a university a red light.

While a ban on “posters promoting alcohol consumption” would be a clear violation because it unambiguously restricts speech on the basis of content and viewpoint, it would not be a substantial violation because of its very limited scope. Alternatively, a policy banning “verbal abuse” would have broad applicability and would pose a substantial threat to free speech, but it would not be a clear violation because “abuse” might refer to unprotected speech, such as threats of violence or harassment as defined in the common law. In other words, the extent of the threat to free speech depends on how such a policy is applied.

Texas is the reason.
