Tuesday’s vote in the House is part political strategy setting up an election-year roll call that will force all lawmakers, Republicans and Democrats, to go on the record with their views on the high-profile social issue. It’s also part of the legislative branch asserting its authority, pushing back against an aggressive court that appears intent on revisiting many settled U.S. laws.

“As this Court may take aim at other fundamental rights, we cannot sit idly by,” Rep. Jerrold Nadler, D-N.Y., the chairman of the House Judiciary Committee, said in a statement.

While the Respect for Marriage Act is expected to pass the House, it is almost certain to stall in the Senate, where most Republicans would surely block it. It’s one of several bills, including those enshrining abortion access, that Democrats are pushing to confront the court’s conservative majority. Another bill, guaranteeing access to contraceptive services, is set for a vote later this week.

The Respect for Marriage Act would repeal a leftover law still on the books from the Clinton era that defines marriage as a heterogeneous relationship between man and woman. It would also provide legal protections for interracial marriages by prohibiting any state from denying out-of-state marriage licenses and benefits on the basis of sex, race, ethnicity or national origin.

The 1996 law, the Defense of Marriage Act, had basically been sidelined by Obama-era court rulings, including Obergefell v. Hodges, which established the rights of same-sex couples to marry nationwide, a landmark case for gay rights.

But last month, in doing away with the Roe v. Wade constitutional right to an abortion, the conservative court majority put in place during the Trump era left critics concerned there may be more to come.

In writing for the majority overturning Roe, Justice Samuel Alito argued for a more narrow interpretation of the rights guaranteed to Americans, saying the right to an abortion is not spelled out in the Constitution.

“We therefore hold that the Constitution does not confer a right to abortion,” Alito wrote.

In a concurring opinion, conservative Justice Clarence Thomas went further, saying other rulings similar to Roe, including those around same-sex marriage and the right for couples to use contraception, should be reconsidered.

While Alito insisted in the majority opinion that “this decision concerns the constitutional right to abortion and no other right,” others have taken notice.

Jim Obergefell, the plaintiff in the landmark ruling legalizing same-sex marriage and now running as a Democrat for the Ohio House, said after the court’s ruling on abortion, “When we lose one right that we have relied on and enjoyed, other rights are at risk.”
