LGBTQ+ Panic Defense Prohibition Act of 2023

This bill prohibits defendants in federal criminal cases from using a victim's LGBTQ+ identity (sexual orientation, gender identity, or expression) as a legal excuse for violence or to reduce sentences - a practice known as the "LGBTQ+ panic defense." It specifically bans arguments that a "nonviolent sexual advance or perception" of the victim's identity justified the crime, while allowing evidence of the defendant's past trauma under standard evidence rules. The law directly affects federal criminal trials where defendants attempt to justify violence against LGBTQ+ victims using prejudice-based excuses. It also requires the Attorney General to report annually on federal prosecutions involving bias-motivated crimes against LGBTQ+ individuals.
