Here’s who to expect from the Plaintiffs on Friday.

- Gregory M. Herek, Ph.D. a Professor of Psychology at the University of California at Davis. He will testify about the nature of sexual orientation, how mainstream mental health professionals and behavioral scientists regard homosexuality, benefits conferred by marriage, stereotypes relating to lesbians and gay men, stigma and prejudice directed at lesbians and gay men, the harm to lesbians and gay men and their families as a consequence of being denied the right to marry, and how the institution of domestic partnerships differs from that of marriage and is linked with antigay stigma.
