Seven individuals have filed a federal lawsuit against President Donald Trump’s executive order, which mandates that the U.S. government only recognize a person’s sex assigned at birth on government-issued documents.

The complaint, filed Friday in U.S. District Court in Massachusetts, accuses the State Department of rejecting passport applications from transgender citizens or issuing documents that do not reflect their gender identity.

One of the plaintiffs, Massachusetts resident Reid Solomon-Lane, described the real-world consequences of the policy in a statement provided by the American Civil Liberties Union (ACLU), which is representing the plaintiffs.

“I’ve lived virtually my entire adult life as a man. Everyone in my personal and professional life knows me as a man, and any stranger on the street who encountered me would view me as a man,” Solomon-Lane said.

He added that the policy has upended his life and jeopardized his safety:

“Now, as a married father of three, Trump’s executive order and the ensuing passport policy have threatened that life of safety and ease. If my passport were to reflect a sex designation inconsistent with who I am, I would be forcibly outed every time I used it, putting me and my family at risk.”

The lawsuit includes seven plaintiffs, but the ACLU reports that over 1,500 transgender individuals and their families have contacted them with concerns about being unable to obtain passports that align with their gender identity.

The case is expected to be a major legal challenge to Trump’s restrictive gender policies, raising questions about civil rights, privacy, and federal recognition of gender identity.
