CONCORD, N.H. (AP) — A New Hampshire bill that would ban transgender athletes in grades 5-12 from teams that align with their gender identity is headed to the governor’s desk.

The Republican-led Senate voted 13-10 along party lines Thursday in favor of a bill that would require schools to designate all teams as either girls, boys or coed, with eligibility determined based on students’ birth certificates.

Supporters of the legislation said they wanted to protect girls from being injured by larger and stronger transgender athletes.

“When we talk about fairness and rights, we can’t cover every circumstance. And so in a very narrow way that I think to most of us is very clear, biological boys have an advantage over biological girls,” said Senate President Jeb Bradley, a Republican from Wolfeboro. “We’ll never be able to legislate total fairness. But what we can’t do is create rights for one at the expense of another.”
