On February 11, 2026, Defending Education (DE) and its co-plaintiffs filed a brief in Defending Education v. Sullivan asking the court for a preliminary injunction, which would stop a Colorado law while the case challenging goes forward, and opposing the state’s motion to dismiss the case.
The lawsuit challenges HB 25-1312, which punishes Coloradans for their speech and forces them to use language endorsing the state’s views on the highly contested political questions of sex and gender. DE argues that the challenged parts of the law violate the First and Fourteenth Amendments, should be declared unconstitutional, and should be blocked.
DE looks forward to a quick ruling that protects its members and everyone in Colorado who does not want to be punished for sharing sincere beliefs about sex and gender.
