The introduction of The California Domestic Partner Rights and Responsibilities Act of 2003 (or Assembly Bill 205 of 2003) marked a major shift in the legislature's approach to domestic partnerships. Earlier efforts afforded domestic partners only certain enumerated rights, which the legislature expanded in piecemeal fashion. This bill, introduced by Assemblymembers Jackie Goldberg, Christine Kehoe, Paul Koretz, John Laird, and Mark Leno, created the presumption that domestic partners were to have all of the rights and responsibilities afforded spouses under state law.
