Sanity prevails… for now.

AUSTIN, Texas (AP) — A federal judge in Texas is blocking for now the Obama administration’s directive to U.S. public schools that transgender students must be allowed to use the bathrooms and locker rooms consistent with their chosen gender identity.

On Monday — the first day of class for most public schools in Texas — hundreds of school districts awoke to news of the order by U.S. District Judge Reed O’Connor.

His decision dated Sunday comes after Texas and 12 other states challenged the Obama directive as unconstitutional. O’Connor ruled that the federal education law, Title IX, “is not ambiguous” about sex being defined as “the biological and anatomical differences between male and female students as determined at their birth.”

He also sided with Republican state leaders who argued that schools should have been allowed to weigh in before the directive was announced in May.
