A measure prohibiting homicide defendants from claiming a defense that panic brought on by a victim’s sexual orientation or gender identity has been passed by lawmakers in Washington state.

Nine states — California, Connecticut, Hawaii, Illinois, Maine, Nevada, New Jersey New York and Rhode Island — have legislatively banned the use of gay or transgender panic as a legal defense.

The Washington measure, passed by the Senate on a bipartisan 46-3 vote Wednesday, is named after Nikki Kuhnhausen, a transgender teen who was killed last year. The legislation now goes to Gov. Jay Inslee for his signature.
