A federal judge issued a temporary injunction Monday to prevent the state of Idaho from enacting a law that would keep biological males out of girls' and women's sports.
Gov. Brad Little signed the Fairness in Women's Sports Act in March after it passed the Idaho Senate earlier that month. The American Civil Liberties Union has since challenged the law in court.
In his ruling in the case, Chief of the U.S. District Court of Idaho Judge David C. Nye wrote that the law "stands in stark contrast to the policies of elite athletic bodies that regulate sports both nationally and globally." He also said that the law would likely be overturned in court and that it discriminates based on a person's transgender status.
Presidents Barack Obama and Donald Trump both nominated Nye.
In June, the Department of Justice filed a statement of interest in the case, defending the Idaho law's constitutionality.
