The policy was challenged in court by groups representing transgender individuals, leading courts across the country to issue nationwide injunctions barring the administration from implementing it. The Supreme Court on Tuesday lifted those preliminary injunctions.
The Trump administration announced in March 2018 that it would bar transgender people from serving in the military but that, after further study, transgender people who serve “in their biological sex” without seeking to undergo gender reassignment surgery would be allowed to serve. The policy also has an exception for troops who began the process of changing their genders under Obama-era rules. The military said last year that over 900 men and women have done so.
