Michigan, Idaho, Montana, North Dakota, and South Dakota have all urged the US Supreme Court to overturn Obergefell v. Hodges, the 2015 decision that federally legalized same-sex marriage. But this move isn’t as straightforward as many activists on both sides would have you believe. Even if Obergefell is ultimately overturned, other laws and rulings complicate things. The Respect for Marriage Act requires states to acknowledge the legal marriages of other states, and United States v. Windsor struck down key parts of the anti-LGBT Defense of Marriage Act. Should Obergefell fall while Windsor stands, same-sex marriages would still be recognized at the federal level, even if individual states banned them. Yet, the implications are deeply troubling. We could return to a system where some states honor same-sex marriages, while others don’t — a legal patchwork that could severely constrain LGBT rights and upend the decades of work leading up to Obergefell. As a 29-year-old lesbian engaged to be married, this turn of events is personal for me. And it may be one I helped contribute to.
