On June 26, 2015, in its 5-4 Obergefell v. Hodges decision, the U.S. Supreme Court legalized same-sex marriage across the country, ruling that state-level bans on same-sex marriage violated the due process and equal protection clauses of the Fourteenth Amendment.

The Supreme Court seemed likely Tuesday to uphold a Biden administration regulation on ghost guns, the difficult-to-trace weapons found at crime scenes in increasing numbers. Key conservative justices seemed open to the government's argument that kits for quickly making nearly untraceable guns at home can be regulated like other firearms, with background checks and serial numbers. The court previously allowed the rule to go into effect, and ghost gun numbers have since dropped in several cities. But manufacturers and gun rights groups argue the Biden administration overstepped by trying to regulate gun parts that had long been legal with hobbyists.

The Supreme Court has upheld a federal gun control law that's intended to protect domestic violence victims. President Joe Biden praised the decision, saying that "no one who has been abused should have to worry about their abuser getting a gun," The justices ruled 8-1 Friday in favor of a 1994 ban on firearms for people under restraining orders to stay away from their spouses or partners. The justices reversed a ruling from the federal appeals court in New Orleans that had struck down the law. It's the justices' first Second Amendment case since they expanded gun rights in 2022. The case involved a Texas man accused of hitting his girlfriend and threatening to shoot her.
