State Senator Bowdler convinced the legislature of State Z to pass a law requiring all professors to submit their class notes and transparencies to a board of censors to be sure that no "lewd" materials were presented to students at state universities. Professor Rabelais would like to challenge this law as being violative of his First Amendment rights under the U.S. Constitution.

a. May Professor Rabelais challenge this law in State Z courts?

b. May Professor Rabelais challenge this law in a federal district court?
