Obergefell v. Hodges (U.S. Supreme Court, 2015) Tanco v. Haslam (U.S. Supreme Court, 2015) Deboer v. Snyder (U.S. Supreme Court, 2015) Bourke v. Beshear (U.S. Supreme Court, 2015)

These cases challenge Ohio's, Tennessee’s, Michigan’s, and Kentucky’s Marriage Bans, state constitutional amendments that define marriage as exclusively between one man and one woman. ADL filed a brief on behalf of a coalition of 25 organizations that recounts how discriminatory laws targeting disadvantaged groups have long been justified by religious and moral disapproval, an argument that has been rejected by the U.S. Supreme Court. The brief also argued that overturning the marriage ban would not only ensure that religious considerations do not improperly influence which marriages the state can recognize, but would also allow religious groups to decide the definition of marriage for themselves.
