Campus sexual assault victims and women's advocacy groups delivered petitions to Brown's office on Sept. 16 urging him to sign the bill. De Leon has said the legislation will begin a paradigm shift in how college campuses in California prevent and investigate sexual assaults. Rather than using the refrain "no means no," the definition of consent under the bill requires "an affirmative, conscious and voluntary agreement to engage in sexual activity." SB967 applies to all California post-secondary schools, public and private, that receive state money for student financial aid. UC President Janet Napolitano recently announced that the system will voluntarily establish an independent advocate to support sexual assault victims on every campus.
