The ABA overwhelmingly adopted a resolution urging state (as well as territorial and tribal) governments to permit same-sex marriage:
RESOLVED, That the American Bar Association urges state, territorial, and tribal governments to eliminate all of their legal barriers to civil marriage between two persons of the same sex who are otherwise eligible to marry.
The Resolution was supported by the ABA Commission on Women in the Profession, as well as by the ABA Young Lawyers Division, the Hispanic National Bar Association, the National Asian Pacific American Bar Association, and the ABA Commission on Racial and Ethnic Diversity in the Profession.
