On May 1, 2014, Judge Yu was appointed by Washington Governor
Jay Inslee to the
Washington Supreme Court, making her the first openly
LGBTQ member of the court, in addition to the first Latina-American and
Asian-American. She is the 11th woman to serve on the Washington Supreme Court (and one of six currently serving), the first person of Asian descent, the third person of Hispanic descent, and the first Hispanic woman. Yu, who is openly gay, is also the first
LGBT person to hold this position. Yu is one of ten
LGBT state supreme court justices currently serving in the United States. She was sworn in on May 20, 2014 as an associate justice of the
Washington Supreme Court. Justice Yu ran unopposed in 2015 to complete the term and was the highest vote getter in the State. Justice Yu was subsequently elected to the Supreme Court for a six-year term in 2016. In October 2018, Yu joined the majority when the court abolished the
state's death penalty because they found its racist imposition violated the
Constitution of Washington. Yu retired from the court on December 31, 2025. ==Personal life==
