Microsoft, Amazon, Expedia, and other tech giants have joined a coalition of more than 200 companies pushing the U.S. Supreme Court to protect LGBTQ people from discrimination.

Next term, the court will rule on three cases concerning whether federal anti-discrimination laws apply to sexual orientation and gender identity.

Nearly every big tech company in America signed a friend-of-the-court brief arguing that laws prohibiting discrimination on the basis of sex should apply to sexual and gender identity. The brief claims that extending those protections would be good for the economy and beneficial to employers and employees.

A group of civil rights organizations, including the Human Rights Campaign, Lambda Legal, and Out Leadership, organized the brief. On October 8, the Supreme Court will hear the trio of cases.

The full list of signatories is available on the Human Rights Campaign website.
