The Supreme Court has decided that it’s so vital to let President Trump keep transgender people out of the military that it has allowed his ban on their service or enlistment to go forward before even hearing arguments on the validity of his discriminatory decision.

The president announced the ban on Twitter in July 2017, surprising even the Joint Chiefs of Staff and his own defense secretary. The Pentagon later tried to get around injunctions that prevented the ban’s implementation by reverse-engineering the policy to suit Mr. Trump’s demands. In a pair of orders on Tuesday, the court lifted two of those injunctions.

One American Civil Liberties Union lawyer called the new and ostensibly improved transgender ban “transphobia masquerading as policy.” And a former naval aviator, reacting to the Supreme Court’s latest move, wrote in a Times op-ed that her career in the armed forces was just dealt a punishing blow.

The justices provided no explanation for their decision, which puts on hold rulings that have been in place for well over a year and that have allowed transgender troops to continue to serve openly under a directive by the Obama administration that was years in the making.
