This award-winning documentary tells the poignant story of Filipino-American Richard Adams and his Australian husband, Tony Sullivan, who in 1975, became one of the first same-sex couples to be legally married in the world. Limited Partnership recounts their 40-year struggle to stay together, and parallels the history of the LGBT marriage and immigration equality movements. In 1975, thanks to a courageous county clerk in Boulder, CO, Richard and Tony were one of the first same-sex couples in the world to be legally married. Richard immediately filed for a green card for Tony based on their marriage. Richard received a denial letter from the Immigration and Naturalization Service stating, "You have failed to establish that a bona fide marital relationship can exist between two faggots." Outraged at the tone, tenor and politics of this letter and to prevent Tony's impending deportation, the couple sued the U.S. government. This became the first federal lawsuit seeking equal treatment for a same-sex marriage in U.S. history. Limited Partnership celebrates Richard and Tony's long path towards justice and citizenship as they challenge the traditional definitions of "spouse" and "family." This tenacious story of love, marriage and immigration equality provide both historical context and deeply moving and personal story that shows how social progress is achieved.
