US Attorney General Jeff Sessions has reversed a federal government policy that said transgender workers were protected from discrimination under a 1964 civil rights law, according to a memo on Wednesday sent to agency heads and US attorneys.

Sessions’ directive, obtained by BuzzFeed News, says, “Title VII’s prohibition on sex discrimination encompasses discrimination between men and women but does not encompass discrimination based on gender identity per se, including transgender status.”

It adds that the government will take this position in pending and future matters, which could have far-reaching implications across the federal government and may result in the Justice Department fighting against transgender workers in court.

“Although federal law, including Title VII, provides various protections to transgender individuals, Title VII does not prohibit discrimination based on gender identity per se,” Sessions writes. “This is a conclusion of law, not policy. As a law enforcement agency, the Department of Justice must interpret Title VII as written by Congress."

But Sharon McGowan, a former lawyer in the Justice Department's Civil Rights Division and now an attorney for the LGBT group Lambda Legal, countered that Sessions is ignoring a widespread trend in federal courts.

"It's ironic for them to say this is law, and not policy," McGowan told BuzzFeed News. "The memo is devoid of discussion of the way case law has been developing in this area for the last few years. It demonstrates that this memo is not actually a reflection of the law as it is — it's a reflection of what the DOJ wishes the law were."

"The sessions DOJ is trying to roll back the clock and pretend that the progress of the last decade hasnt' happened," she added. "The Justice Department is actually getting back in the business of making anti-transgender law in court."
