SACRAMENTO, Calif. (AP) — An anti-tax group filed a lawsuit Thursday against California State University, Monterey Bay over an email sent by a professor urging students to support Proposition 30, the governor’s tax initiative on the November ballot.

The lawsuit by the Howard Jarvis Taxpayers Association, filed in Monterey County Superior Court, said the email was sent from a university Internet address to more than 360 CSU-issued email addresses.
