Joe Biden signed an XO allowing trans people to serve openly in the Armed Forces. On Day 1, Donald Trump revoked that XO. Several trans soldiers sued. Lower courts have repeatedly ruled that Trump has failed to show that trans soldiers are not as good as other soldiers and so that ban is unconstitutional under the equal protection provision of the 14th Amendment. Yesterday, the Supreme Court ruled that he can ban trans soldiers for the time being, while the legal process plays out. Yesterday's unsigned decision (with dissents from the three liberal women) vindicates Trump's position for the moment. The case will now go to the U.S. Court of Appeals for the Ninth Circuit for a full hearing.
The Pentagon, pursuant to Trump's XO, issued an order to each branch to identify all service members with gender dysphoria within 30 days and remove them. That process was stopped by the lower courts. It can now continue until the Supreme Court eventually rules on the merits of the case. Given that the Tuesday ruling was apparently 6-3 along partisan lines, there is a pretty good chance that the final ruling will go the same way. (V)
