When Jack Baker proposed to Michael McConnell that they join their lives together as a couple, in March 1967, McConnell accepted with a condition that was utterly radical for its time: that someday they would legally marry. Just a few years later, the U.S. Supreme Court slammed the door on the men’s Minnesota lawsuit to be the first same-sex couple to legally marry in the U.S. It took another 40 years for the nation’s highest court to revisit gay marriage rights, and Baker and McConnell — still together, still living in Minneapolis — are alive to see it. On Friday, the justices decided to take a potentially historic look at gay marriage by agreeing to hear two cases that challenge official discrimination against gay Americans either by forbidding them from marrying or denying those who can marry legally the right to obtain federal benefits that are available to heterosexual married couples. “The outcome was never in doubt because the conclusion was intuitively obvious to a first-year law student,” Baker wrote in an email to The Associated Press. The couple, who have kept a low profile in the years since they made national headlines with their marriage pursuit, declined an interview request but responded to a few questions via email.
