"Case No. S147999 in the Supreme Court of the State of California, In re Marriage Cases Judicial Council Coordination Proceeding No. 4365, Application for leave to file brief amici curiae in support of the parties challenging the marriage exclusion, and brief amici curiae of the American Psychological Association, California Psychological Association, American Psychiatric Association, National Association of Social Workers, and National Association of Social Workers, California Chapter in support of the parties challenging the marriage exclusion": "The scientific research that has directly compared outcomes for children with gay and lesbian parents with outcomes for children with heterosexual parents has been remarkably consistent in showing that lesbian and gay parents are every bit as fit and capable as heterosexual parents, and their children are as psychologically healthy and well-adjusted as children reared by heterosexual parents. Amici emphasize that the abilities of gay and lesbian persons as parents and the positive outcomes for their children are not areas where credible scientific researchers disagree. Statements by the leading associations of experts in this area reflect professional consensus that children raised by lesbian or gay parents do not differ in any important respects from those raised by heterosexual parents. No credible empirical research suggests otherwise."
