Anti-discrimination law
The Civil Rights Act of 1964 was the first major development in anti-discrimination law in the US, though prior civil rights legislation (such as the Civil Rights Act of 1957) addressed some forms of discrimination, the Civil Rights Act of 1964 was much broader, providing protections for race, color, religion, sex, or national origin in the areas of voting, education, employment, and public accommodations. This landmark legislation led the way for other federal legislation, which expanded upon the protected classes and forms of discrimination prohibited under federal legislation, such as the Fair Housing Act or the Americans with Disabilities Act. These protections have also been expanded through the courts interpretation of these pieces of legislation. For example, the 7th and 2nd circuit courts have both ruled that employment discrimination based on sexual orientation is a violation of Title VII of the Civil Rights Act. In addition to federal legislation, there are numerous state and local laws that address discrimination that is not covered by these laws.
Transgender legal history in the United States
In 2012 the Equal Employment Opportunity Commission expanded upon these individual court cases by ruling that Title VII (of the Civil Rights Act of 1964) does prohibit gender identity-based employment discrimination as sex discrimination. The Equal Employment Opportunity Commission declared, "intentional discrimination against a transgender individual because that person is transgender is, by definition, discrimination 'based on ... sex' and such discrimination ... violates Title VII". This ruling was for a discrimination complaint filed by the Transgender Law Center on behalf of transgender woman Mia Macy, who had been denied a job due to her gender identity. The ruling opens the door for any transgender employees or potential employees who have been discriminated against by a business hiring 15 or more people in the US based on their gender identity to file a claim with the EEOC for sex discrimination.
