California is on the brink of becoming the first state to define when "yes means yes" while investigating sexual assaults on college campuses.

SB967 passed the Assembly on Monday on a 52 to 16 vote. It now returns to the Senate for a final vote on amendments.

The legislation by Democratic Sen. Kevin de Leon of Los Angeles requires investigations of sexual assaults to seek whether "affirmative consent" was granted.

Silence or lack of resistance is not consent under the standard, nor is consent while a victim is drunk.

It applies to all colleges and universities accepting state money for financial aid. Some Republican lawmakers say the bill overreaches by regulating bedroom activity.

The bill also requires schools to have "victim-centered" sexual assault response protocols and comprehensive prevention programs.
