SOUTHFIELD, Mich. (AP) — Two Detroit-area nurses whose lawsuit erased Michigan’s ban on gay marriage and played a role in making it legal across the country have exchanged vows.

April DeBoer and Jayne Rowse wed Saturday in Southfield. Federal Judge Bernard Friedman, who struck down the state’s ban, performed the ceremony.

Between 250 and 300 family members and friends attended the wedding at a banquet hall. DeBoer wore a cream-colored wedding dress and Rowse a black tuxedo.

The couple sued the state after they couldn’t jointly adopt each other’s children. That case grew into a challenge to a Michigan constitutional amendment that recognized marriage only between a man and a woman.

Friedman overturned the state’s gay marriage ban in 2014. In June, the U.S. Supreme Court said same-sex couples have a right to marry.
