The state constitution prohibits marriage between same-sex couples. Amended in 2002 to read: “Only a marriage between a male and female person shall be recognized and given effect in This state.” See Nevada Constitution, Article 1 § 21.
All government employees are protected by the U.S. Constitution against irrational discrimination based on sexual orientation or gender identity. In addition, some measure of protection already exists under Title VII based on gender, which has been held to include gender identity and expression.
The U.S. Equal Employment Opportunity Commission (EEOC) and several courts have interpreted Title VII to protect transgender employees, and the EEOC has interpreted Title VII to cover sexual orientation discrimination. The Supreme Court has held that the EEOC's interpretations of Title VII are entitled to "great deference."
