“In a 50-page, 4–3 ruling on November 18, 2003,[3] the Massachusetts Supreme Judicial Court found that the state may not “deny the protections, benefits and obligations conferred by civil marriage to two individuals of the same sex who wish to marry.”
The court gave the State Legislature 180 days to “take such action as it may deem appropriate” before issuing marriage licenses to same-sex couples.[1]”
