A transgender woman has won a landmark discrimination case against the Bureau of Alcohol, Tobacco and Firearms (ATF).

Mia Macy, who claimed to have been rejected from a potential job opportunity with the ATF after she revealed she was transgender, will now be receiving a renewed job offer and additional compensation.

The Department of Justice ruled that ATF broke anti-discrimination laws when it refused to hire the police detective after she told them she was transgender.

Macy is highly-qualified in ballistics tracking work and managing ATF’s computer systems, reportedly one of 40 people in the entire US certified to use the agency software. During the hiring process, she informed the agency that she had gender identity disorder and had undergone feminine facial reconstruction surgery.

According to the Huffington Post, Macy was told she was rejected because of budgets cuts, but was ‘stunned’ to learn later the agency had hired someone else for the role.

Macy’s case resulted in a ruling that the federal sex discrimination law protects individuals from termination or discrimination in the workplace for being transgender or gender non-conforming.

According to the Transgender Law Center based in northern California, The Department of Justice ruled that the Bureau of Alcohol, Tobacco and Firearms (ATF) has been ordered to re-offer Macy the role, in addition to paying out damages. The ATF is also charged with ensuring future employees and job applications are not discriminated against based on their gender identity.

‘This is truly historic,’ said Ilona Turner, legal director of the Transgender Law Center.

‘Employers everywhere need to understand that they will be held accountable if they discriminate against transgender people.’

‘We’re thrilled for Mia that justice has been served, and we are incredibly proud to have worked with her to change the legal landscape for transgender Americans moving forward.’

Macy said in a statement: ‘It’s a victory for all transgender people to know that we have a voice, that we have recourse, and that when it comes to workplace protections we deserve to make a living. I couldn’t be happier.’
