“(d) This section does not prohibit the imposition of discipline for harassment, threats, or intimidation, unless constitutionally protected. . . .
“(f) The Legislature finds and declares that free speech rights are subject to reasonable time, place, and manner regulations.”
The “time, place, and manner regulations” restriction doesn’t apply here, because the restriction here was justified with reference to the content of the expression (and the supposed harm that it might cause). Time, place and manner regulations must be unrelated to content, and focused instead on matters such as noise, blockage of hallways and other effects of speech that don’t stem from the message that the speech communicates. But apparently § 48950 wasn’t brought up in the litigation.
