The Supreme Court stalled the Biden administration’s updated Title IX rules in 26 states, creating an uneven patchwork of application of the controversial regulatory overhaul in schools as students across the country return from summer break.

The impact of the Supreme Court’s decision on Friday is already being felt in schools nationwide. In the 26 states where the new rules are blocked, schools are operating under the old Title IX guidelines, meaning 24 Democratic-led states, including Illinois, Pennsylvania, and New York, are operating under the new rules.
