Transgender recruits will be able to join the U.S. military as of Jan. 1, a federal judge ruled on Monday, denying a request by President Donald Trump's administration to enforce his ban on transgender troops while the government appeals an order blocking it.

U.S. District Judge Colleen Kollar-Kotelly in Washington refused to lift part of her Oct. 30 order stopping the ban from taking effect until the case is resolved, because it likely violates the U.S. Constitution's guarantees of due process and equal protection under the law.

The administration had argued that the Jan. 1 deadline was problematic because tens of thousands of personnel would have to be trained on the medical standards needed to process transgender applicants, and the military was not ready for that. Kollar-Kotelly rejected the concerns, saying that preparations for accepting transgender troops were underway during the administration of Trump's predecessor, Barack Obama.
