The state's "Subversive Activities Registration Act," passed last year and now officially on the books, states that "every member of a subversive organization, or an organization subject to foreign control, every foreign agent and every person who advocates, teaches, advises or practices the duty, necessity or propriety of controlling, conducting, seizing or overthrowing the government of the United States ... shall register with the Secretary of State."

There's even a $5 filing fee.
Yeah it's a little too old, but gwahir can suck it
