In a statement Monday, BART management said, "BART accommodates expressive activities that are constitutionally protected by the First Amendment to the United States Constitution and the Liberty of Speech Clause of the California Constitution (expressive activity), and has made available certain areas of its property for expressive activity." But it said there are limits.
"Paid areas of BART stations are reserved for ticketed passengers who are boarding, exiting or waiting for BART cars and trains, or for authorized BART personnel. No person shall conduct or participate in assemblies or demonstrations or engage in other expressive activities in the paid areas of BART stations, including BART cars and trains and BART station platforms."
